Corn Sugar


As I was scanning an ingredient label recently (unfortunately, I can't recall the product), I noticed something that I'd never seen before - corn sugar. I did some googling, and it seems that it is merely a new name for high fructose corn syrup (HFCS). I've covered HFCS (here), and I'm not convinced of the extreme evils for which it is blamed. However, I would recommend limiting all simple carbohydrates and getting plenty of excercise. This is easier said than done, of course.

Here are two sources that explain more about corn sugar:

First is an NPR article, from 2010:
Would "high fructose corn syrup" sound so sweet by any other name? The Corn Refiners Association sure hopes so. Last week, the industry group applied to the federal government for permission to use a new name for the ingredient on food labels: "corn sugar."

Whether it's called high fructose corn syrup or corn sugar, the ingredient makes up a significant part of Americans' diets. According to the Agriculture Department, the average American ate 35.7 pounds of high fructose corn syrup last year. That's not such a surprise considering it's used as a sweetener in everything from fruit-flavored drinks and energy bars to jams, yogurts and breads.

The second, www.cornsugar.com, is put on by the Corn Refiners of America, who say:

Health and nutrition experts—including doctors, dietitians, researchers and professional organizations — are in agreement that whether it’s corn sugar or cane sugar, your body can’t tell the difference. Sugar is sugar.

One issue I have concerns this statement, as it conveniently omits the large amounts of government subsidies to produce corn and tariffs that keep cane sugar less competitive:

If high fructose corn syrup is the same as sugar, then why don’t we just use sugar?
The introduction of high fructose corn syrup into the food supply was intended to overcome periodic shortages in sugar availability and resulting price increases (as is the case now). High fructose corn syrup also avoided the problems posed by sugar’s instability in acidic soft drinks and fruit preparations, bagged sugar’s handling difficulties, and sugar’s functional limitations in certain foods and beverages.

Much of the debate over the overuse of HFCS could be alleviated by allowing free market forces to determine the true prices of food.

It also appears that corn sugar is used in home beer brewing:

Where to Buy Evaporated Cane Juice


Many visitors arrive to this blog asking "Where can I buy Evaporated Cane Juice?". One easy answer: Amazon. While Amazon has always been known for new books, many people are unaware of the extensive selection of other goods. From electronics to food, cosmetics to toys, one can find just about anything. Along the left margin of my blog, one can find my list of recommended products. I also recommend checking out their selection of used books for out of print volumes and a more economical way to build a library.

Big Baby



He’s a bouncing baby boy who could break a knee — a mother in Jakarta, Indonesia, delivered a 19.2-pound, 2-foot-long child on Monday via Caesarean section.


The big baby, a weight record for a newborn in Indonesia, although a bit short of the world record of 23 pounds set in 1879, was likely caused by his mother having gestational diabetes. And even though mom Ani was saved the grueling task of pushing the child out herself, the surgery to bring him into the world was still touch and go.

A Look at Agave Nectar


This article, from Radish Magazine, takes a critical look at a natural sweetener that has recently gained popularity - agave nectar.

For those who are not familiar with agave nectar, it is a syrupy sweetener produced from the juices of a succulent plant resembling a cactus. Numerous species of agave plants are native to Mexico and the Southwestern U.S.--one of which is used to make tequila. A mature agave plant may be up to 8 feet tall with leaves spreading out to a diameter of 12 feet!

The agave nectar is sold in many health food stores (in light, amber, dark and raw varieties) for general sweetening purposes and also incorporated as a sweetening agent in many so-called organic, raw and/or diabetic-friendly health foods. It is portrayed as an unrefined and healthful sweetener, but the truth is a much more complex story.
...

The chemical and genetically-modified enzymatic processes used to manufacture the juices into agave nectar end up giving it a profile of 70 percent or more as fructose, compared to only 55 percent fructose found in HFCS. (Raw honey contains only about 38 percent fructose.) Concentrated levels of fructose in the diet may lead to mineral depletion, inflammation of the liver, hardening of the arteries, insulin resistance, high blood pressure, cardiovascular disease and obesity.

While it is true that high levels of dietary fructose will not necessarily cause spikes in blood glucose, agave nectar certainly still falls short of being a healthful alternative. It is for this reason that noted low-carb advocate, Dr. Michael Eades, M.D., has said of agave nectar: "Avoid it like death."

A less-than-ideal sugar profile may be offset somewhat by the presence of abundant minerals, which agave nectar reportedly has, including iron, calcium, potassium and magnesium. However, it is more correct to say that the juices of the agave plant contain an abundance of such minerals (as well as valuable amino acids) rather than the resultant agave nectar. While "miel de agave" retains these factors, modern processing removes many of them in order to make the taste of the agave nectar lighter and more palatable.

Alternative Sugar Names


Here's a list of various sweeteners that you may not recognize as sugar on an ingredient list. Some were quite surprising. (link)

Barley malt. A sweetener produced from sprouted barley that is mostly maltose. It is used in combination with other sweeteners and for cooking and baking.

Brown rice. A sweetener produced commercially by cooking brown rice flour or syrup brown rice starch with enzymes. It can be used for cooking and baking and is sometimes combined with fruit concentrates to be used in food products.

Brown sugar. A refined sugar coated with molasses.

Cane syrup. A very sweet syrup made from sugarcane.

Corn syrup. A manufactured syrup of cornstarch that contains varying proportions of glucose, maltose, and dextrose. It is used in salad dressings, tomato sauces, powdered drink mixes, fruit drinks and juices, and desserts like pudding and ice milk.

Crystalline. A sweetener that is made from cornstarch and comes in granules fructose like table sugar. It is used in dry mix beverages, low-calorie products, enhanced or flavored water, still and carbonated beverages, sports and energy drinks, chocolate milk, breakfast cereals, baked goods, yogurt, fruit packs, and confections.

Dextrose. Another name for glucose. A simple sugar that is less sweet than fructose or sucrose. It is used in many baking products like cake mixes and frostings, snack foods like cookies, crackers, and pretzels, and desserts like custards and sherbets.

Fructose. A sugar found naturally in fruit; also a simple sugar refined from fruit.

High fructose. A highly concentrated syrup of mostly fructose and some corn syrup glucose that is prevalent in soft drinks and other processed foods.

Honey. A concentrated solution of fructose and glucose, plus some sucrose. It is produced by bees from the nectar of flowers.

Invert sugar. A sugar created by heating sugar syrup with a small amount of acid such as cream of tartar or lemon juice in order to reduce the size of the sugar crystals. The resulting product is smoother and suitable for use in candies and some syrups.

Lactose. A simple sugar in milk.

Maltodextrin. A sugar made from maltose and dextrose in corn. It is used in a wide array of foods, from canned fruits to snacks.

Maltose. A simple sugar made from starch.

Mannitol, sorbitol, xylitol. Sugar alcohols derived from fruit or produced from dextrose. These sweeteners are used in many dietetic products. Sugar alcohols do not promote tooth decay, unlike sugar.

Maple syrup. A concentrated sap from maple trees, predominantly fructose. Molasses The thick syrup by-product from the processing of sugarcane or sugar beet into sugar. Blackstrap molasses, a popular health food, is a good source of calcium, iron, and potassium.

Muscovado or Barbados sugar. A British specialty brown sugar that is very dark brown and has a particularly strong molasses flavor. The crystals are slightly coarser and stickier in texture than “regular” brown sugar.

Sucanat. Nonrefined cane sugar that retains all of its molasses content.

Sucrose. Refined, crystallized sap of the sugarcane or sugar beet; a combination of glucose and fructose.

Turbinado. A less refined sugar that still has some natural molasses coating.

White grape juice. A highly purified fructose solution. Virtually no other nutrients are present. It is often used in juice concentrate blends.

News Flash!


Hey folks, a new study shows cutting down on sugary drinks is a way to lose weight!

Consumption of liquid calories from beverages has increased in parallel with the obesity epidemic. Earlier studies by Bloomberg School researchers project that 75 percent of U.S. adults could be overweight or obese by 2015 and have linked the consumption of sugar-sweetened beverages to the obesity epidemic, which affects two-thirds of adults and increases the risk for adverse health conditions such as type 2 diabetes. Researchers recommend limited liquid calorie intake among adults and to reduce sugar-sweetened beverage consumption as a means to accomplish weight loss or avoid excess weight gain.
I've also heard that expending more calories than you consume will do the same thing.

New Ag Secretary Tom Vilsack


Obama's new Agriculture secretary has already made some steps to promote local food. First, is a stricter interpretation of a labeling directive in the last farm bill. Mexico and Canada both oppose such "country of origin" labels, since meat packers can now mix US and foreign meat without notifying consumers. I fully support free trade - and have large reservations about 'Buy American' laws. This, however, only gives the consumer information. The consumer can make the choice to support the producer he wishes, rather than being left in the dark.

The labeling requirements, which would apply to fresh meats and some perishable fruits and vegetables, have long been debated in Congress. While the meat industry and retailers responsible for the labels have protested the changes — saying they are burdensome and could lead to higher prices — consumer groups and northern state ranchers who compete with the Canadian beef industry favor them.
Another interesting step is to create community garden projects at all USDA facilities worldwide.
During today's ceremony, Secretary Vilsack announced the goal of creating a community garden at each USDA facility worldwide. The USDA community garden project will include a wide variety of garden activities including Embassy window boxes, tree planting, and field office plots. The gardens will be designed to promote "going green" concepts, including landscaping and building design to retain water and reduce runoff; roof gardens for energy efficiency; utilizing native plantings and using sound conservation practices.
...
The garden will showcase conservation practices that all Americans can implement in their own backyards and green spaces. As a component of the garden, pollinator-friendly plantings will not only provide important habitat for bees and butterflies, but can serve as an educational opportunity to help people understand the vital role pollinators play in our food, forage and all agriculture. The garden plot is adjacent to the site of the USDA Farmer's Market.

Peanut Butter Recall Update


As the peanut butter recall expands, it is beginning to appear that the Salmonella outbreak was more than an accident. It had been reported that the Peanut Corporation of America had shipped products that had previously been positive for Salmonella but then had retested negative. This is bad enough, but now this article claims that they even sent out product without retesting...thus they knowingly and intentionally sent out tainted peanut products.

"In some situations the firm received a positive salmonella test result, followed by a later negative result, and then shipped the products," said the FDA report, which was included in an e-mail to CNN. "In some other situations, the firm shipped the products [which had already tested positive] before it had received the [second] positive test results."

In some cases, it said, "no additional testing appears to have been done."

No one from the company returned a call seeking comment.

Federal authorities have initiated a criminal investigation into the company.

The Farms Race


While the world's nations vie for control of affordable energy, another equally important commodity may cause conflict in the future - food. And perhaps more importantly, the fertile land on which food is produced. This article highlights cash rich/arable land poor countries that are purchasing large swaths of such land.

The Saudis are not alone in the global land grab. Any country that worries about long-term food security because of a shortage of fertile land, and has the wealth to do something about it, is on the hunt: United Arab Emirates, Jordan, Libya, India, China, Japan, plus a number of investment and private-equity funds. A report published in the autumn by the United Nations International Fund for Agricultural Development said that "public and private corporations and industrial groups are buying millions of hectares of land in Africa, Asia and Latin America to produce food or agrofuels."
This could end up affecting Western nations as well. I have previously highlighted how American farmland is decreasing rapidly. This fact, juxtaposed with the parable of Squanderville vs. Thriftsville, should be cause for alarm.

How to Dry Foods


How to Dry Foods. Deanna DeLong. Recommended.

A food dehydrator was on my Christmas list this year, and as luck would have it, one appeared under the tree. A fairly comprehensive instruction manual accompanied the dehydrator, but I thought I would look for more guidance. This book seems to be a complete guide for home food drying. All major foods are covered: fruits, vegetables, meats, herbs, spices, nuts, and seeds. Not only does the text list foods that are great for drying, but it cautions against others that are only marginal. This will save countless hours of fruitless trial and error.

The recipe section has many jerky marinade formulations and fruit leather mixtures. Also included are many recipes that use the dried products, so you know what to do with all the things you have preserved.

I would highly recommend this if you are interested in food dehydration. Thus far I have made some pretty decent beef jerky and dried pineapple. Perhaps as I gain more skill I will post some of my favorite recipes.

Peanut Butter Recall


For the past week, the FDA has been investigating a Salmonella outbreak in peanut butter. See their website for up to date information and specific product recalls.

January 18, 2009: The Food and Drug Administration (FDA) is conducting a very active and dynamic investigation into the source of the Salmonella Typhimurium outbreak. At this time, the FDA has traced a source of Salmonella Typhimurium contamination to a plant owned by Peanut Corporation of America (PCA), which manufactures both peanut butter that is institutionally served in such settings as long-term care facilities and cafeterias, and peanut paste—a concentrated product consisting of ground, roasted peanuts—that is distributed to food manufacturers to be used as an ingredient in many commercially produced products including cakes, cookies, crackers, candies, cereal and ice cream.
...
At this time, there is no indication that any national name brand jars of peanut butter sold in retail stores are linked to the PCA recall. As the investigation continues over the weekend, and into next week, the FDA will be able to update the advice based on new sampling and distribution information.
Similar to the tomato outbreak last summer, this highlights one of the drawbacks of an industrial food chain. Pathogens can spread rapidly to millions of people, and attempting to find the ultimate source can be a nearly impossible task. This makes the case for local food even more compelling. While a local food chain is certainly not immune to food-borne illness outbreaks, the impacts are localized, which makes them smaller as well as easier to find and remedy.

Local Harvest


I found a great site for locating "local" food in your area. Localharvest.org lists farms and CSAs from around the country, just enter your zip code and they'll point you in the right direction. Also don't forget to check out Eatwild.com, as well, for grass fed meats.

I believe that eating local food is a choice that can positively affect many of the problems that we currently are facing. Here are some of the benefits that I see:

Ideally, local food takes less fossil fuel energy to produce. Since the food is produced close to you, it will not have to take cross-continent trips in a semi-truck.

The food should arrive quicker and fresher than that which is shipped long distances. Many industrial food chain produce varieties are chosen for their durability, not flavor. Those huge strawberries at the grocery store are pretty, but many times are rather hard and tasteless. Local producers can grow varieties that are tastier and healthier, and can pick them at peak freshness.

Local, unprocessed food is more likely to be "real" food. As described in In Defense of Food, highly processed food - dense in calories yet light in nutrients - is a major cause of the obesity epidemic in Western culture. Real, whole foods are the true "part of a complete, nutritious breakfast".

Since the food chain is dramatically shortened, much of the obscuration is removed, allowing the consumer to make truly informed decisions. You might actually be able to go to the source and even meet the person who is ultimately responsible for how your food is produced. With all the curtains pulled back, you now can tell how "natural", "sustainable" or "organic" your produce and meat really are, and not rely on a mere label in the grocery store.

More of your food dollar goes to the person who produces the food, rather than the industrial conglomerate that processes and ships it. Every layer of middle men you cut out is more money flowing to the actual producer. Bad for ADM and General Mills, good for the farmer and you.

So, check out these sites, look for farmer's markets in your area and become an active consumer.

Eat Safe


Eat Safe. Bill Statham. Recommended.

I found this book while perusing the new arrivals at the library, and it seems to be quite a good reference. As suggested by In Defense of Food, we should probably only eat foods that have a minimal amount of processing, and we should be able to pronounce and understand all the ingredients. If you've spent much time looking at labels, this can be a daunting task. Certain additives may sound horrible, yet be perfectly safe...and vice versa.

The book lists hundreds of ingredients and gives each a ranking - beneficial ones get two smiley faces, down the scale to two sad faces for dangerous substances. The entire list is also color coded (red, yellow and green) for quick reference. In addition to the rankings, there is a column for function, potential effects, food uses, and other uses.

I would recommend this guidebook for a quick reference, but with some caveats. Food science and medical advice changes over time, so the recommendations may not hold up as research advances. Also, certain substances affect people in different ways, so some "safe" ingredients may be dangerous for a small minority of the population. Overall, however, the book seems well researched and very comprehensive.

Global Economic Prospects 2009: Commodities at a Crossroad


The World Bank released its latest Global Economic Prospects report for 2009. Since it deals nearly exclusively with commodities, I thought it might have some interesting nuggets to explore. Today I'll post the link to the pdf, the introduction, as well as some of its key findings - and hopefully break down some commentary in the coming days.

The release of this year’s Global Economic Prospects finds the world economy at a crossroads. Markets all over the world are engulfed in a global economic crisis, with stock markets sharply down and volatile, almost all currencies having depreciated substantially against the dollar, and risk premiums on a wide range of debt having increased by 600 or more basis points. Commodity markets too have turned a corner. Following several years of increase, prices have plummeted, and although well above their 1990s levels, they have given up most of the increases of the past 24 months.

Chapter 1 of this report examines the medium-term implications of this crisis for
developing-country growth, inflation, and world trade. Chapter 2 looks at longer-term supply and demand prospects in commodity markets. It takes into account the long-term growth prospects of developing countries and their rising share in world GDP (gross domestic product), the declining quality of new pools of resources, and the influence of technology on both demand and supply. Finally, chapter 3 reports on the poverty impacts of high commodity prices and examines
the effectiveness of policies in both producing and consuming countries in dealing with the challenges posed by periodic bouts of high commodity prices.

This report does not deal with water, fish, or timber, all commodities of critical importance to developing countries and the globe but which fall outside the scope of this report either because of their public-goods character or, in the case of timber, because of its treatment in a recent report (World Bank 2007).
Key Findings:
  1. The global financial crisis threatens short term prospects in developing countries
  2. Uncertainty continues to cloud the outlook
  3. The commodity market boom has come to an end
  4. Commodity prices are declining in response to slower GDP growth
  5. In the longer term, growth in the demand for commodities should ease
  6. Moderating demand for metals depends critically on increased efficiency in China
  7. Future energy demand depends onimproving automobile efficiency
  8. Over the next 20 years, supplies of extracted commodities are likely to remain ample
  9. Food demand will slow with lower population growth, but biofuels could expand crop demand very rapidly
  10. Strong productivity growth and unused crop land should ensure adequate food supply at the global level
  11. Commodity-producing countries are managing the revenue windfall better than they have in the past
  12. High commodity prices pose challenges for the poor, especially in consuming nations
Lots of interesting topics to cover...

Global Trends 2025: Scarcity in the Midst of Plenty


As highlighted in the previous two posts, Chapter Four deals with resources - and the possibility of conflict that could arise when these resources become scarce. Three main resources - the basics of life - have the highest potential for tension: food, water, and energy. While energy tends to dominate the headlines, food and water may loom just as large for certain populations.

Experts currently consider 21 countries with a combined population of about 600 million to be either cropland or freshwater scarce. Owing to continuing population growth, 36 countries, home to about 1.4 billion people, are projected to fall into this category by 2025.
...

The World Bank estimates that demand for food will rise by 50 percent by 2030, as a
result of growing world population, rising affluence, and shifts to Western dietary
preferences by a larger middle class. The global food sector has been highly responsive to market forces, but farm production probably will continue to be hampered by misguided agriculture policies that limit investment and distort critical price signals. Keeping food prices down to placate the urban poor and spur savings for industrial investment has distorted agricultural prices in the past. If political elites are more worried about urban instability than rural incomes—a safe bet in many countries—these policies are likely to persist, increasing the risk of tight supplies in the future. The demographic trend for increased urbanization—particularly in developing states—underscores the likelihood that failed policies will continue.
...

In addition to the currently projected scarcities of freshwater and cropland, the UK
Treasury-commissioned Stern Report estimates that by the middle of the century
200 million people may be permanently displaced “climate migrants”—representing a ten-fold increase over today’s entire documented refugee and internally displaced
populations. Although this is considered high by many experts, broad agreement exists about the risks of large scale migration and the need for better preparation. Most displaced persons traditionally relocate within their home countries, but in the future many are likely to find their home countries have diminishing capabilities to accommodate them. Thus the number of migrants seeking to move from disadvantaged into relatively privileged countries is likely to increase. The largest inflows will mirror many current migratory patterns—from North Africa and Western Asia into Europe, Latin America into the US, and Southeast Asia into Australia.
We in the U.S. may not think these resources are ever in danger, but in recent years there have been disputes over water rights in several Southern states. Not just in traditional desert states - in 2007 Georgia and the Carolinas had major water shortages. And water shortages could spell trouble for those who rely on irrigation to produce crops as well. The Ogallala Aquifer in the midwest is being rapidly depleted, per wikipedia:

The Ogallala Aquifer is being depleted at a rate of 12 cubic km (420,000 million ft3 or 9.7 million acre feet) per year, amounting to a total depletion to date of a volume equal to the annual flow of 18 Colorado Rivers. Some estimates say it will dry up in as little as 25 years. Many farmers in the Texas High Plains, which rely particularly on the underground source, are now turning away from irrigated agriculture as they become aware of the hazards of overpumping.
A comparable replacement for this water may simply not exist, and a large portion of the folks that rely on this water for drinking and employment may be forced to make very difficult choices. And the millions of people who rely on the food grown in these states will be competing for reduced global reserves.

Sugar and the Environment


High Fructose Corn Syrup has a bad reputation for many reasons; both its health and environmental effects have been derided quite a bit in the last few years. As I examined in this post, some of these have more merit than others. Before one decides to switch from HFCS to sugar for environmental reasons, however, the ecological effects of sugar cane should be examined. My inspiration for this post was a segment of Bill Nye's "Stuff Happens" on Planet Green. He pointed out that sugar production is killing the Great Barrier reef and the Everglades, so I thought I'd dig around a bit to see what others had to say.

Digression: Am I the only one who finds a lot of Planet Green's programming to be really annoying? I can only take so much of Hollywood-types telling me how much money they "save" by installing PV solar cells on their roofs of their 10,000 sq.ft. palatial estates. Sure you have a smaller power bill...but how much did you spend upfront to install them? Have your accountant run the real numbers and get back to me. Don't go patting yourself on the back to hard, you might strain something. Anyway, back on track...

According to this report, Sugar and the Environment, produced by the World Wildlife Fund, cane sugar has some major effects on the environment. The report is very detailed, but I will include some highlights here.

The cultivation and processing of sugar produce environmental impacts through the
loss of natural habitats, intensive use of water, heavy use of agro-chemicals, discharge and runoff of polluted effluent and air pollution. This leads to the degradation of wildlife, soil, air and water where sugar is produced and of downstream ecosystems.

Although many of the environmental impacts of cane and beet cultivation are generic to agriculture, some impacts are distinct, particularly in their severity. Impacts relating to irrigation of sugar cane and pollution runoff are of particular concern.
Environmental Impacts
Sugar cultivation and processing impacts on biodiversity and ecosystem services at the field, farm and wider landscape levels.
Field Level: Soil erosion, compaction, salinisation and acidification

Farm Level:
The suite of micro-organisms associated with a crop is often overlooked, although it
plays such a critical role in ecosystem function, for example in the turnover of soil
organic matter. Most intensively cultivated agro-ecosystems are relatively lacking in
biodiversity.
Landscape Level:
Impacts of sugar cultivation on downstream ecosystems: Agriculture is arguably the
predominant influence on the Earth’s land surface and undoubtedly represents the
main cause of wetland habitat loss. This occurs through the runoff of polluted effluent
into water courses, due to the heavy abstraction of freshwater resources upstream
of wetlands habitats, or by altering the natural flow regime.

The impacts felt downstream are the cumulative result of a complex set of land
and water use decisions in a river basin. Within this context, cane or beet can play
an important role in some sugar producing countries.

The sugar industry in Australia has been a significant player in major infrastructural projects, including damming of the Burdekin, Tully and Barron Rivers, which has altered the pattern of freshwater flow into the Great Barrier Reef lagoon.
Cane growing has shown to increase sediment and nutrient loads, particularly following heavy rainfall, which can carry these materials into the sea, reducing water quality and impacting on inshore reefs. The sediment export rate in the lower South Johnstone River has been estimated at 180,000 tonnes of fine sediment/year, with sugar cane farming contributing to these sediment loads.

Phosphorus-rich runoff from sugar cane fields in Florida is held largely responsible for the decline of the Everglades. The Everglades is a naturally nutrient-poor wetland where sawgrass thrived because naturally low levels of phosphorous inhibited the growth of more aggressive species, such as cattails. However, the common practice of spreading phosphorus on the cane fields in the Everglades first caused the sawgrass to grow abnormally large before dying back to give way to cattails, which have now spread across more than 50,000ha of conservation areas, crowding out willow and bay and excluding fish.
Causes of Impacts

Habitat Clearance
Half of the world’s wetlands have been lost to drainage and conversion to agriculture
(70-90 percent in Europe and USA), and even protected wetland areas are subject
to agricultural impacts. Low-lying and alluvial areas in particular have typically been
reclaimed and drained for sugar cane cultivation, as they often support the richest
soils and enjoy a good natural water supply.
Overuse of Water
Although sugar cane is an efficient converter of biomass from water, it still needs about 1500-2000mm/ha/year and ranks among a group of crops noted for their significant water consumption (along with rice and cotton). It is a deep-rooted crop, which remains in the soil all year round and is able to extract soil water to depths well below one metre. In areas where sugar cane growth relies on rainfall, the crop can influence river flows as it intercepts run-off from the catchment into rivers and taps into ground water resources.
Intensive Use of Chemicals
Intensive agricultural food production in general uses high levels of pesticides
(herbicides, insecticides, fungicides, nematicides, rodenticides, plant regulators,
defoliants or desiccants), with herbicides representing about 50 percent of pesticides
used in many countries. A wide variety of pesticides are used in the cultivation of sugar crops. Herbicide use in sugar beet is among the highest compared to other crops.
Discharge of Processing Mill Effluents
Perhaps the most significant impact from cane and beet processing is related to
polluted effluent. In some countries with weak environmental laws, when sugar mills
are annually cleaned, a tremendous amount of matter is released, which is usually
discharged straight into streams. Cane mill effluents tend to be relatively rich in organic matter compared to other sources, and the decomposition of this matter reduces the oxygen levels in the water, affecting natural biochemical processes and the species inhabiting those freshwater systems. Potential pollutants in these effluents include heavy metals, oil, grease and cleaning agents.
Pre-Harvest Cane Burning
In many sugar producing countries, the cane fields are burnt immediately before harvesting
for easier cutting, post harvest cultivation and pest control.
While it has benefits, it also causes air pollution, soil degradation and a reduction in sugar yield.

Another thing to keep in mind is the distance sugar takes to get to your plate. Since it is primarly grown in tropical climates, it may have been shipped thousands of miles. This would no doubt increase the "carbon footprint". Luckily, we produce a lot domestically in Florida, but this is not without environmental consequences.

As this report (and Bill Nye) points out, even the most unassuming and ubiquitous products can have large, and perhaps unrealized, environmental impacts.

Farmer in Chief


Here is the counterpoint to yesterday's post, Nutrients for Life. "Farmer in Chief" is an open letter to our next President, written by Michael Pollan, the author of In Defense of Food. He outlines his vision for modifying American agricultural policy to positively influence three of our most pressing issues. No doubt you have heard the presidential candidates debate over how to solve our dependence on foreign energy, our health care system and the specter of global climate change. Since agriculture is such a cornerstone of our society, the author asserts that changes could provide positive results in all three of these issues.

Whenever farmers clear land for crops and till the soil, large quantities of carbon are released into the air. But the 20th-century industrialization of agriculture has increased the amount of greenhouse gases emitted by the food system by an order of magnitude; chemical fertilizers (made from natural gas), pesticides (made from petroleum), farm machinery, modern food processing and packaging and transportation have together transformed a system that in 1940 produced 2.3 calories of food energy for every calorie of fossil-fuel energy it used into one that now takes 10 calories of fossil-fuel energy to produce a single calorie of modern supermarket food. Put another way, when we eat from the industrial-food system, we are eating oil and spewing greenhouse gases. This state of affairs appears all the more absurd when you recall that every calorie we eat is ultimately the product of photosynthesis — a process based on making food energy from sunshine. There is hope and possibility in that simple fact.
The author outlines his ideas for improvement, which all involve major shifts in agriculture policy. I've included excerpts here, but please read the entire article.

Step 1, Resolarizing the American Farm:
What happens in the field influences every other link of the food chain on up to our meals — if we grow monocultures of corn and soy, we will find the products of processed corn and soy on our plates. Fortunately for your initiative, the federal government has enormous leverage in determining exactly what happens on the 830 million acres of American crop and pasture land.

Your challenge is to take control of this vast federal machinery and use it to drive a transition to a new solar-food economy, starting on the farm. Right now, the government actively discourages the farmers it subsidizes from growing healthful, fresh food: farmers receiving crop subsidies are prohibited from growing “specialty crops” — farm-bill speak for fruits and vegetables. (This rule was the price exacted by California and Florida produce growers in exchange for going along with subsidies for commodity crops.) Commodity farmers should instead be encouraged to grow as many different crops — including animals — as possible. Why? Because the greater the diversity of crops on a farm, the less the need for both fertilizers and pesticides.

It will be argued that sun-food agriculture will generally yield less food than fossil-fuel agriculture. This is debatable. The key question you must be prepared to answer is simply this: Can the sort of sustainable agriculture you’re proposing feed the world?

There are a couple of ways to answer this question. The simplest and most honest answer is that we don’t know, because we haven’t tried. But in the same way we now need to learn how to run an industrial economy without cheap fossil fuel, we have no choice but to find out whether sustainable agriculture can produce enough food.

The second point to bear in mind is that yield isn’t everything — and growing high-yield commodities is not quite the same thing as growing food. Much of what we’re growing today is not directly eaten as food but processed into low-quality calories of fat and sugar. As the world epidemic of diet-related chronic disease has demonstrated, the sheer quantity of calories that a food system produces improves health only up to a point, but after that, quality and diversity are probably more important. We can expect that a food system that produces somewhat less food but of a higher quality will produce healthier populations.
Step 2, Regionalizing the Food System:

For your sun-food agenda to succeed, it will have to do a lot more than alter what happens on the farm. The government could help seed a thousand new polyculture farmers in every county in Iowa, but they would promptly fail if the grain elevator remained the only buyer in town and corn and beans were the only crops it would take. Resolarizing the food system means building the infrastructure for a regional food economy — one that can support diversified farming and, by shortening the food chain, reduce the amount of fossil fuel in the American diet.

A decentralized food system offers a great many other benefits as well. Food eaten closer to where it is grown will be fresher and require less processing, making it more nutritious. Whatever may be lost in efficiency by localizing food production is gained in resilience: regional food systems can better withstand all kinds of shocks. When a single factory is grinding 20 million hamburger patties in a week or washing 25 million servings of salad, a single terrorist armed with a canister of toxins can, at a stroke, poison millions. Such a system is equally susceptible to accidental contamination: the bigger and more global the trade in food, the more vulnerable the system is to catastrophe. The best way to protect our food system against such threats is obvious: decentralize it.
Step 3, Rebuilding America's Food Culture:
In the end, shifting the American diet from a foundation of imported fossil fuel to local sunshine will require changes in our daily lives, which by now are deeply implicated in the economy and culture of fast, cheap and easy food. Making available more healthful and more sustainable food does not guarantee it will be eaten, much less appreciated or enjoyed. We need to use all the tools at our disposal — not just federal policy and public education but the president’s bully pulpit and the example of the first family’s own dinner table — to promote a new culture of food that can undergird your sun-food agenda.

Changing the food culture must begin with our children, and it must begin in the schools. Nearly a half-century ago, President Kennedy announced a national initiative to improve the physical fitness of American children. He did it by elevating the importance of physical education, pressing states to make it a requirement in public schools. We need to bring the same commitment to “edible education” — in Alice Waters’s phrase — by making lunch, in all its dimensions, a mandatory part of the curriculum. On the premise that eating well is a critically important life skill, we need to teach all primary-school students the basics of growing and cooking food and then enjoying it at shared meals.

The president should throw his support behind a new Victory Garden movement, this one seeking “victory” over three critical challenges we face today: high food prices, poor diets and a sedentary population. Eating from this, the shortest food chain of all, offers anyone with a patch of land a way to reduce their fossil-fuel consumption and help fight climate change. (We should offer grants to cities to build allotment gardens for people without access to land.) Just as important, Victory Gardens offer a way to enlist Americans, in body as well as mind, in the work of feeding themselves and changing the food system — something more ennobling, surely, than merely asking them to shop a little differently.

I don’t need to tell you that ripping out even a section of the White House lawn will be controversial: Americans love their lawns, and the South Lawn is one of the most beautiful in the country. But imagine all the energy, water and petrochemicals it takes to make it that way. (Even for the purposes of this memo, the White House would not disclose its lawn-care regimen.) Yet as deeply as Americans feel about their lawns, the agrarian ideal runs deeper still, and making this particular plot of American land productive, especially if the First Family gets out there and pulls weeds now and again, will provide an image even more stirring than that of a pretty lawn: the image of stewardship of the land, of self-reliance and of making the most of local sunlight to feed one’s family and community. The fact that surplus produce from the South Lawn Victory Garden (and there will be literally tons of it) will be offered to regional food banks will make its own eloquent statement.
Pollan is a good author, and makes his views seem quite easy to implement. I can see some major hurdles to these policy changes, however, and some minor quibbles with several of his points.

1. Economic troubles.

As money gets tight, food price increases will be hard to politically justify. It does not matter that food prices are at historic lows...perhaps the cheapest of any civilization, ever. People already started bitching about food increases this past year...it is an American right, cheap food and fuel.

Large scale unemployment, however, may provide a large base of manpower for more labor-intensive agriculture. Perhaps many people get a first-hand look at what jobs migrant workers are currently "stealing" from the American public.

2. Farmers as "drivers".
Farming without fossil fuels — performing complex rotations of plants and animals and managing pests without petrochemicals — is labor intensive and takes more skill than merely “driving and spraying,” which is how corn-belt farmers describe what they do for a living.
I find this to be quite patronizing. I know no farmer who would honestly describe himself in such a way. I suspect the author did not pick up on the humility and self-deprication of his subject. Organic farming is more labor intensive, that point is well recieved. Adding more human capital to the agricultural system will be a challenge of its own. But to say it takes no skill to run a modern farm is ludicrous. It takes a decidedly different set of skills, and new organic skills will need to be learned and disemminated. As the average age of the American farmer increases, this will be more and more difficult. It will take a youth movement, and few people (young or old) today are interested in the arduous and capricious way of life found in agriculture.

3. Energy Calorie per Food Calorie.
...a system that in 1940 produced 2.3 calories of food energy for every calorie of fossil-fuel energy it used into one that now takes 10 calories of fossil-fuel energy to produce a single calorie of modern supermarket food...
Much of this certainly can be explained by the long distances that food now travels. The other factor is that millions of farmers have left the business and there are simply much less human calories at work. This has been supplanted by fossil fuels.

4. Supermarket for the World

Some opponents of organic agriculture point to the fact that we might not be able to maintain the huge outputs of food that we once did. I tend to subscribe to the notion that it is not our duty to feed the entire world. Many of his suggested policies may lower the amount of available food. For years, our subsidized grain has driven world prices down, not allowing indigenous people to economically farm. Now will be their chance. I also feel grain prices are a great geopolitical lever that we control. China has become quite reliant on us, importing more and more in the last few years. We must not neglect this as a bargaining tool.

5. A Matter of Taste

The rise of the industrial food system was helped along by policies, but it rests on the simple fact that all people like to eat cheap, tasty, sweet, fatty and salty foods. This small, sticky fact will not go away, it is hard-wired in our DNA. It will be very hard to convince people to pay more for food that they do not prefer. However, the author brings up the pertinent point - this cheap, unhealthy food is being subsidized. Not only by farm subsidies for grain, but by our increasing health insurance premiums. If we remove these incentives and force people to pay the true cost, the decision calculus may begin to swing in a more healthy direction. The huge amount of political capital and will to do this may be simply unattainable, however.


All in all, there are some very interesting ideas contained in his letter. I believe that less reliance on huge agribusiness and heavier reliance on local small agriculture has many benefits. Whether we can make such a transition remains to be seen. The individual consumer now has more of a choice than ever; buy fresh, organic, local food and provide a market for these products. Don't eat fast food and prepackaged meals. Grow a garden. Small steps by large amounts of people can have huge impacts.

Prebiotics vs. Probiotics


I recently noticed the terms "probiotic" and "prebiotic" on yogurt packaging and advertisements. I had heard of probiotics before, and assumed them to be the "live and active cultures" that give yogurt its supposed health benefits. I was not 100% sure of this, however, and "prebiotic" was certainly a new one to me, so I decided to look them up. Here's what I found:

Probiotics

As I originally suspected, probiotics refer to a group of microorganisms - bacteria and yeasts - that have potential health benefits. They generally must be live organisms to be truly considered probiotic. A precise definition (and health benefits) are actually in debate in the medical and health community.

These cultures are thought to help out the naturally occurring microbes in your stomach and intestinally tract. They can be implemented after a round of antibiotics to restore the natural "gut flora" of one's body. Some use probiotic products to prevent and treat certain illnesses and support general wellness. One thing to keep in mind - there are a wide number of microorganisms that are considered probiotic; and effects found from one species or strain of probiotics do not necessarily hold true for others, or even for different preparations of the same species or strain.

Yes, El Guapo, I would say there are a plethora of sources for probiotics. The two main ways to introduce them into a diet are through supplements and food. Since I view supplements with a high sense of skepticism, I would most likely recommend sticking with real food. Also, the probiotics must be alive to work, so supplements must be refrigerated like food anyhow. Probiotic foods include the aforementioned yogurt, as well as fermented and unfermented milk, miso, tempeh, kiefer, and some juices and soy drinks. Some may find these selections rather unappealing; but given the wide range of choices, there should be something for everyone's palate.

Prebiotics

And now for the question of the day - What are prebiotics? Quite simply, they are food for probiotics. Prebiotics are indigestible (to humans) substances that can stimulate the growth and vitality of the microorganisms in one's digestive tract. Prebiotics are normally classified as carbohydrates, and quite often a type of fiber.

Prebiotics can be found in grains - such as soybeans, oats, wheat, and barley. Inulin - group of naturally occurring polysaccharides - is another source, and it can be derived from jerusalem artichoke, jicima, chicory root, and yacon (yeah, I've never heard of that either). Inulin is becoming widespread as a food additive for its wide range of characteristics and applications. Not only does it have probiotic properties, it contains much less caloric energy than sugar, it ranges from bland to subtly sweet, and it can be used to replace sugar, fat, and flour.

Much like probiotics, prebiotics are not completely understood. Experts agree that adding them to one's diet is beneficial, but specific advice varies widely. Certain benefits include: intestinal regularity, increased mineral absorption, increased immune system response, and bowel pH adjustment. Be aware, however - a sudden increase in substaintial quantities of prebiotics have been shown to cause a temporary increase in gas, bloating and/or bowel movements. So take it easy - yikes.
