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:

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.

Health Care Reform Ideas


Here are some common sense ideas for the health care reform debate, from the CEO of Whole Foods. Let's hope some of them make it in any bill that's finally cobbled together and attempted to be rammed through Congress.

Some highlights:
- Medicare/Medicaid reform
- Make individual health insurance tax deductible just like employer-provided insurance
- Tort reform
- Cost transparency so consumers can make informed decision about their own health

Health care reform is important - the costs really are skyrocketing. However, the government should take a real long hard look in the mirror and actually address the sources of the increases. Shifting the costs around only makes the problem worse.

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.

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.

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.

The Self-Sufficiency Handbook - and a Few "Deep Thoughts"


The Self-Sufficiency Handbook: A Complete Guide to Greener Living. Alan and Gill Bridgewater.

As I have said many times before, I truly doubt the existence of a complete self-sufficiency book. While this text boldly proclaims as such in the title, I have not yet been proved wrong. This handbook has a lot of great information, but it is rather thin...and would serve best as only a light introduction to self-sufficiency. It would not be undesirable in a library, but hardly necessary. For those so inclined, I have two superior recommendations here and here. I would not have even written a review, however the opening paragraph struck me, and I want to share it - and my thoughts - with you.

When Gill and I graduated from art school in the 1960s, the whole place was buzzing with a new kind of freedom. Somehow we all felt that we could do it - meaning life - better than previous generations. I remember one evening sitting in a college common room listening to two young, hippy, American lecturers animatedly talking about how very soon we would all be forced by the failure of oil supplies to return to some sort of Amish type self-sufficiency - log cabins maybe, horses rather than cars, communes where groups of like-minded people pulled together to create a better society - and it was very exciting.

As they saw it, and as whole swathes of people saw it, our consumer society was living off the fast shrinking capital resources of the earth. Their thinking was that ever since the start of the industrial revolution we had been taking and dumping: taking the coal and dumping the waste, taking the oil and dumping pollution, taking the goodness from the soil and leaving it barren, cutting down trees, and so on.
The authors continue on, explaining how this shaped their desire to live in a self-sufficient and less ecologically impacting manner. They then spent the next 30-40 years of their lives scrounging around, trying to make ends meet. As I also have stated before, the romanticism of self-sufficiency does not fool me. I don't find it that exciting and I do not think it would be an ideal way to live. Anyway, the introduction instantly struck me in two ways:

1. Maybe there really is no urgent problem
2. Crying wolf...and its ramifications

First off, my gut reaction was, "Man, people really have been screaming, 'The end is nigh!' for a long time." Maybe all the people screaming about it now really are full of it, too. Maybe peak oil and global warming are not that big of a deal...and if they are, maybe they are decades or centuries away from affecting us.

Then, that little seed of doubt creeps back in. Perhaps the hippies back then were right all along, just off in the time frame. My mind continues to file through all the evidence that I have complied during the short amount of time that I have concerned myself with such matters. Yes, peak oil must be real, and the while the time frame is up for debate, the one that I have settled on is definitely within my lifetime, or at least the next generation's.

Global warming is a challenge that I have yet to tackle, and I am not a climatologist. I will have to default to the consensus of current scientific opinion and Al Gore. I fear that it is real, it is man-made, and due to the Tragedy of the Commons, it may be inevitable. The time frame on climate change is very much up for debate as well, due to its extremely complex and variable nature; but if you watch the Discovery Channel, you know it is coming pretty soon - and will not be pretty.

So, the long standing cries from environmentalist and other scientists may have been 'spot on' the entire time. Perhaps it was the relevance time between the earth's geologic clock and the 24-hr news cycle that has caused the disconnect. And ultimately, the fable of the "Boy Who Cried Wolf" seems rather fitting; and rather disturbing, considering the end result.

These are the two extremes I continue to wrestle with. And as I have argued in the past, few things in life are black and white. For my own benefit, (and hopefully yours) I will continue to attempt to search through the gray area. Depending on the source, you can get pretty good (and bad) arguments from both sides. There are folks with full time jobs that research these issues, as well as those that literally devote their entire lives to finding the truth. How can the layman be expected to sort through it all? I suppose all we can do is just continue to plug along; hoping for the best and preparing for some version of the worst.

Nike+ Sport Band


I have been testing the Nike+ Sport Band with varied success.

Pros:
The trendy wristband with clock and digital read out is very user friendly and barely noticeable while running.

Just unplug your wristband piece and pop it into a USB port on your computer and your workout is uploaded to the Nike+ homepage that tracks your mileage.

The cost ($60) is very reasonable.

Cons:
I have had varying success with the accuracy of the band. My first run was horrendous, partly because proper directions were practically nonexistent (think IKEA, only 10 times worse). But, I calibrated it after the first run and it has been almost perfect since. I double check my mileage with mapmyrun.com

Overall, I've been rather pleased with the Nike+ Sport Band. Has anyone else used this or higher end devices such as Garmin?

High Fructose Corn Syrup


As I have examined Evaporated Cane Juice and Sugar in these posts, I thought I might start a discussion about High Fructose Corn Syrup (HCFS). HCFS has recently become a bad word in nutrition circles, and many folks are starting to avoid it at all costs. Here are two commercials that are intended to start a bit of a dialog, and perhaps question that conventional wisdom:






What do you think? Do these videos and the accompanying website spin the truth? Is High Fructose Corn Syrup that much worse than regular sugar? Perhaps we should not take a commercial enterprise at its word...I did some preliminary searches for medical studies:

http://www.ncbi.nlm.nih.gov/pubmed/18469239
CONCLUSIONS: Sucrose and HFCS do not have substantially different short-term endocrine/metabolic effects.
http://www.ncbi.nlm.nih.gov/pubmed/17616770
CONCLUSION: There was no evidence that commercial cola beverages sweetened with either sucrose or HFCS have significantly different effects on hunger, satiety, or short-term energy intakes.

In addition, animal studies have shown a link between increased consumption of high-fructose corn syrup and adverse health effects, such as diabetes and high cholesterol. However, the evidence is not as clear in human studies.

Despite the lack of clarity in research, the fact remains that Americans consume large quantities of high-fructose corn syrup in the form of soft drinks, fruit-flavored beverages and other processed foods. These types of foods are often high in calories and low in nutritional value. This fact alone is reason to be cautious about foods containing high-fructose corn syrup.

Do you avoid HCFS? Perhaps avoid all simple carbohydrates? Maybe you eschew carbs altogether? I'd love to hear your thoughts.

Eating on $100 a Week?


Here is an interesting article chronicling a family of four's attempt to eat for a week, spending only $100. With increasing energy and food costs, this may be harder than ever. I know our family has been attempting to lower our overall costs, and food is one area that is up for examination. One must balance thrift with health, however, and eating only mac and cheese and mayo sandwiches is not advised.

Some interesting facts and ideas from the article:

- A food stamp allowance for a family of four is $117
- A $100 budget gave us $1.19 a meal per person (wow)
- "Americans are obsessed with protein, but it's the one nutrient we actually get too much of"
- Planning is key: if you do not buy enough, you'll have to go back and end up spending more (impulse items)
- "The most inexpensive snacks are also some of the healthiest"

It should be noted that as Americans, we recently have spent less of food as a percentage of household income than ever in history (less than 10%). Even with recent increases due to higher energy prices; we still spend relatively little on food. Compared to the rest of the world, this number is high on absolute terms, though. A main reason for this is the large amounts of processed and convenience foods that we eat. Pound for pound, prepared and processed foods cost much more than 'real' food.

If one factors the time involved in preparation, some packaged foods may come out ahead economically, depending on your salary. This says nothing about the nutritional value, however, and the increase in quick food has a strong correlation to our expanding waistlines.

As the article notes, some fresh vegetables did not fit in the super-econo budget. (Organics are even pricier) But as it also noted, this was a budget that was under a poverty level. By substituting many name-brand, convenience, and packaged foods with whole, healthy ones, American's could cut our food budgets by large amounts and our middle sections as well.

Another idea: adding a prolific back yard garden could help your wallet and waistline, also.

Lemond Poprad Review



Lemond Poprad 2008

I purchased the Poprad after riding several different Cyclocross bicycles. I preferred the Poprad over the Specialized Tricross and Surly Crosscheck.

Some highlights quotes from the Lemond website:
Poprad is a city in Slovakia where Matt Kelly won the first American World Championship in Cyclocross—on a LeMond.


Pros:
The front and rear derailleurs are the Shimano 105 and Ultegra; so smooth you can not even tell you have shifted. The feel of the ride is smooth but it also seems to handle more like a road bike than the Specialized.

The steel frame is made in the USA, which was a selling point for me. The seat post and front fork are carbon.

Aesthetically, the Poprad is a hands down winner. The white frame with white handlebars is SICK!!


Cons:
It set me back about $1500, whereas the Surly, my second choice, was a couple hundred less.

Specialized Langster 2007 Update: Part 3



a full two months(see original post) - here's what I think...

On an overall scale, I would say the Langster ranks 8.5 out of 10.

Pros - The Langster is light-weight and fun to ride, a good work out on hills, and a great conversation starter with the ladies. Not to dwell too much on that point, but the chicks dig the Langster. I use the bike 4-5 times per week and at least 5-6 miles per day. I know, not a heavy workout routine by any means, but for someone with a busy schedule and is not in the best shape in the world, I think the mileage and frequency is adequate enough. I feel my leg muscles tightening up and toning by the day.

Cons - While I liked the single-gear aspect initially, it can be a bit of a pain from time to time, especially when going downhill. Not uphill? No no, that's what I enjoy the most. If there is any type of downhill slope, pedaling becomes virtually impossible and you're at the mercy of the bike to "bottom-out", so to speak. The one long ride I did take, roughly 25-30 miles, I wished to have several gears just to switch things up, but in the end, it was not a huge deal.

So why did I rate the Specialized Langster at 8.5 out of 10? For the price range, I would rate it 9.5 out of 10, but I tried out other bikes during the interim since my previous post and more expensive bikes are obviously better. With that being said, I felt my bike at roughly a third of the price of the other bikes I rode is a steal to say the least.

Five Financial Costs of Obesity


Here is a Newsweek article that lists five major costs of American obesity. The results are compiled from several recent studies and other sources.

1. Lower Wages
2. Less Hours Worked
3. Higher Medical Costs
4. Higher Airfare
5. Less Fuel Economy

The last one seems to be a bit of a stretch. Even several hundred pounds will only slightly affect fuel economy. Over the entire country I suppose this would add up, but any small effect will add up if multiplied by 300 million.

There is another angle, however: larger individuals will no doubt opt for larger vehicles, which in turn does have a significant effect. Also, as the average American increases in size, automakers must continually readjust auto size, thus building larger and larger vehicles to keep up with demand.

Can you think of any other areas where obesity would have added, perhaps hidden, costs?

Evaporated Cane Juice vs. Sugar, Part II


As I noted in this post, I was skeptical about the differences between Evaporated Cane Juice and regular table sugar. As I found, the difference is negligible, and the price would not seem to justify the small amount of nutrients that might be found in Cane Juice. I found an article that examines the issue a bit more, this time examining the health ramifications of simple carbohydrates.

First, the author lists the plethora of alternate names that "sugar" has picked up in the health food aisle:

Perhaps because it sounds like it fits in with a New Age mentality, a lot of manufacturers are using the word "crystals" in describing their sweetening agents nowadays. But sugar they are. To list just a few, there are: cane juice crystals, dehydrated cane juice crystals, unrefined cane juice crystals, raw cane crystals, washed cane juice crystals, Florida crystals (a trademarked name), unbleached evaporated sugar cane juice crystals, crystallized cane juice, and unbleached crystallized evaporated cane juice. There are also products with such names as organic dehydrated cane juice, unbleached sugar cane, evaporated cane juice, and evaporated cane juice sugar.
There are many supposed benefits to these products that have been processed less; and organic products are most likely better for the environment. But since these products are chemically equivalent to sugar, how will they affect your health? The first expert to weigh in, a nutritionist, laments that folks should not think these products are a healthy substitute for sugar:

VanDien's assessment of sweeteners is pretty rigorous. She thinks virtually every commonly used sweetener is as bad as sugar when it makes up a significant part of the diet, as it does for too many Americans.

"Whether you're talking about cane sugar, honey, barley malt or Sucanat (a tradenamed product), they're all primarily simple sugars, simple carbohydrates," VanDien explains. "People should be concerned that, if they're eating 150 pounds of sugar a year and you change that to 150 pounds of barley malt, you'll have the same problems with your immune system and blood sugar levels you would have if you are eating the sugar."

The second expert, with a PhD in nutrition, agrees:
"It's a question of economics," says Fuchs. "Health food stores and manufacturers are capturing dollars from products that are not necessarily the best quality or the healthiest. Some of the companies that use things such as evaporated cane juice say they've studied it and find that people metabolize their sugars more slowly than refined sugar. But I find people who have the same problems with evaporated cane juice as they do with regular sugar. And I deal with people all over the country. I find that people who react to sucrose, or refined sugar, are reacting in the same way to evaporated cane juice," says Fuchs.
She does feel that some sweeteners are superior to sugar, however:
Fuchs does feel that some alternative sweeteners are clearly better than sugar, or the so-called lesser refined sugars. "Sugar is 93 percent sucrose. That's different than barley malt, which is maltose and glucose, and different than maple syrup, or fruit juice concentrate. You can't say those are the same things as sugar when their chemical compositions are different."
The main point I gleaned from the article, is that while there is no really 'healthy' substitute for simple sweeteners, a little will not kill you.
But while VanDien faults sugar for not being "nutrient dense," she also says that "almost anything, in moderation, is not bad. I think balance and moderation are the key words.
However, since most Americans eat very large quantities, they could kill you. In the words of St. Augustine, "To many, total abstinence is easier than perfect moderation."

Fat Future?


According to a new study, if current trends persist, 100% of American adults will be overweight in 40 years :

The figure might sound alarming, or impossible, but researchers say that even if the actual rate never reaches the 100-percent mark, any upward movement is worrying; two-thirds of the population is already overweight.

"Genetically and physiologically, it should be impossible" for all U.S. adults to become overweight, said Dr. Lan Liang of the federal government's Agency for Healthcare Research and Quality, one of the researchers on the study.
I tend to think that extrapolating data out for many years like this is not very accurate, and I would hope there will be a few holdouts from the ranks of the heavy. The overwhelming size of the problem cannot be ignored, however. Our healthcare system and other entitlement benefits are already extremely strained. If everyone is fat...what hope do we have?
