Fructose Linked to Obesity, Diabetes

Engineer-Poet writes "Eurekalert announces that researchers at the University of Florida have demonstrated a link between fructose consumption and metabolic syndrome (a precursor of adult-onset diabetes). In part, it makes you feel hungrier than you should be. This is particularly bad for Americans, because sugar price supports have created a market for fructose as a substitute in almost everything. Dr. Richard J. Johnson says, "If you feed fructose to animals they rapidly become obese, with all features of the metabolic syndrome, so there is this strong causal link. And a high-fructose intake has been shown to induce certain features of the metabolic syndrome pretty rapidly in people." Eating fructose causes a rise in uric acid in the bloodstream. Uric acid in turn blocks the action of insulin, which regulates metabolism (including uptake by fat cells). Elevated uric acid levels can eventually cause features of metabolic syndrome, including high blood pressure, obesity and high cholesterol. The good news is that the action of uric acid can be blocked with drugs, and we can change what we eat. If enough of us boycott fructose and corn-syrup products, the market will respond."

      I believe you are writing about the tarrifs from an American perspective. I believe most of your carbonated beverages (Pespi, Coke) use corn syrup. I live in Canada and our pop is made with Cane sugar.

      I think the larger problem is the amount of sugar in food today. Pepsi and Coke have 40 grams of sugar per can. If people want to drink Pepsi or Coke I have no problem (I do on occasion), but this is way too much sugar. (This says nothing of the health risks of artificial sweetened version of popular soft drinks. I know plenty of people who react to Aspartame, I know I do).

      Some processed foods also have corn syrup added: Salami, other cold-cut meats. Some packaged chicken also has some I believe (at least in Canada, depends on the 'brand' of chicken purchased).

      When you combine the effects of the high-sugar North American diet and lack of activity with a high fructose intake you have a problem. If you eat within the food 'pyramid' and eat 3 or 4 fruit servings a day there is no harm.

      We make cane sugar here. Using corn for sugar is a waste.
      You need fertile fields to make corn, and it's a good crop to feed people.
      Sugar cane grows in the worts fields, needs much less care, doesn't need you to use your fertile lands that could be used for actual food, and so is much less expensive to produce.

      Here in Uruguay, Pepsi is sweetened with sugar cane, and Coca-Cola, with corn syrup, and most people prefer the taste of Coca-Cola. Corn syrup is mre expensive here than cane sugar, so maybe people like expensive stuff, no matter what it is.

      Based on what I've seen and heard, the price you pay for pop in the store has little to do with the manufacturing cost and much more to do with market forces: they *can* charge you $X, so they do. As such, if the sugar-based pop is more expensive, it's much more likely to be either a scale issue, a transportation issue, or just another market issue.

      If I remember correctly, a pound of sugar is a couple bucks. (I might not be remembering right, though.) That's about 2,200 grams of sugar for around two dollars, or about 10 grams for 1 cent. The cost of the roughly 40 grams of sugar in a can of pop would be about 4 cents. That's probably right to within a factor of two, anyway. And it's probably nearer an overly expensive estimate: buying sugar in bulk would probably decrease the unit price *and* I haven't subtracted out the cost of the corn syrup. Given this, it seems improbable that doubling the price (say from 25 cents a can to 50 cents a can) would be purely due to the cost of the sugar used.

      Yeah, damn politicians, always mucking with the free market. They should leave it alone and it would work just like Adam Smith describes here:

      Classical free market economic theory originated with Adam Smith and David Ricardo in the early days of the Industrial Revolution (late 1700s, early 1800s). It was intended to apply under certain conditions and certain conditions only, namely:

      (1) All business was small-to-medium sized and entrepreneurial (not corporate). -- http://www.gwb.com.au/gwb/news/economic/280198.htm l

      Wait a minute. Did Adam Smith's free market only work for non-corporate business? So what happens when society is infested with corporations, some of them being multi-national corporations? I wonder what else Adam Smith had to say:

      (2) The free market was defined as a market of potentially unlimited numbers of these small/medium sized businesses, competing on a more or less equal footing, in a market which newcomers could freely enter, and in which none could control prices.

      Hrm, but how could you stop a corporation with monopoly power from controlling prices? You'd almost need to have a larger and more powerful organisation that represented the will of the people. An organisation that had the power to punish corporations for attempting to control prices. I wonder what you might call a large powerful organisation that represented the will of the people? What other fascinating insights did Adam Smith have with regards to the free market:

      (3) The economy was national; capital must not flow freely across national borders or the theory did not hold (Ricardo)(5).

      Wow, that's a mighty big limitation on the allegedly "free" market. It's almost as if the free market doesn't work when considered in a global scale. I suppose you'd say that Adam Smith's theory didn't work in the event of globalization of the free market. Fortunately that large powerful organisation that represented the will of the people would surely stop capital from flowing freely across national borders. What more can Adam Smith teach us about the free market!

      (4) The market had to be supervised by a sovereign government which (a) protected the public interest (b) made sure all businesses played by the rules (c) provided a stable currency, and (d) ran public utilities, which were regarded as not profitable for private enterprise.

      Well fuck me dead with a barbed wire back scratcher. It seems Adam Smith supported the idea of a sovereign government - that was the word I was searching for to describe that large powerful organisation that represented the will of the people - to ensure that the free market ran smoothly.

      But what the hell would Adam Smith know about a free market. I am intrigued by your ideas that politicians should stop "mucking" with the free market and I would like to subscribe to your (non-union child labour produced) newsletter.

The goal of labels is not to inform consumers, it is to sell products, and the only agency responsible for regulating this, the FDA, is in the pocket of the food companies and rarely even enforces its own policies.

      Since the actual content of food here is so non-obvious, it takes a huge amount of awareness, ingredient reading, and careful research about the contents of each common ingredient, just to monitor what toxins go into ones diet here. It's nowhere near as easy as just not going to McDonalds, when the vast majority of foods in the grocery stores are of identical content.
