High Fructose Corn Syrup Makes You Fat

Maybe you've seen television ads saying that HFCS (high fructose corn syrup) is healthy, good for you, and not any different than eating sugar? I haven't seen them because I don't watch TV, but I have been hearing about these ads. All you have to do to know if the ad is factual is look at who paid for it. The corn industry paid for it? Well then, of course, it is biased. What they don't tell you is this: fructose is metabolized in the liver where it is turned directly into lipids and triglycerides. Sucrose and glucose are processed in the intestine and transported into the blood, where they can be used to fuel muscles and nerves. Furthermore, fructose doesn't give your body what it needs to feel satisfied or full, so no matter how many calories you take in that way, you will still want to eat more. So eating fructose makes you fatter faster. Here's Mercola's version:

High Fructose Corn Syrup Does NOT Metabolize in the Same Way as Sugar

HFCS is a highly processed product that contains similar amounts of unbound fructose and glucose. Sucrose, on the other hand, is a larger sugar molecule that is metabolized into glucose and fructose in your intestine.

Part of what makes HFCS such an unhealthy product is that it is metabolized to fat in your body far more rapidly than any other sugar, and, because most fructose is consumed in liquid form, its negative metabolic effects are significantly magnified.

Whereas the glucose in other sugars is used by your body, and is converted to blood glucose, fructose is a relatively unregulated source of fuel that your liver converts to fat and cholesterol.

There are over 35 years of hard empirical evidence that refined man-made fructose like high fructose corn syrup metabolizes to triglycerides and adipose tissue, not blood glucose. The downside of this is that fructose does not stimulate your insulin secretion, nor enhance leptin production. (Leptin is a hormone thought to be involved in appetite regulation.)

Because insulin and leptin act as key signals in regulating how much food you eat, as well as your body weight, this suggests that dietary fructose may contribute to increased food intake and weight gain.

Additionally, fructose is also known to significantly raise your triglycerides and LDL (bad cholesterol).

Triglycerides, the chemical form of fat found in foods and in your body, are not something you want in excess amounts. Intense research over the past 40 years has confirmed that elevated blood levels of triglycerides, known as hypertriglyceridemia, puts you at an increased risk of heart disease.

I wish it did that for me! I'm 6'3 and 130 lbs. I don't take HFCS any more (or even much sugar) but I did have a lot of it when younger and never weighed more than I am now.

Do you know why you are so lean? How is your GI function? Are you absorbing your food?

I think it's just that I don't eat as much as I should -- my impression is that most people my height eat 3000+ calories a day, whereas I eat 1500-2500 calories a day last time I counted for a week or so. I'll count again this week to see if it has changed, since last I counted was a few years ago.

I don't know what a GI function is, how do I measure it? How do I measure whether I'm absorbing food?

There's not a direct way to measure, but you can check some aspects nutrition status with blood panels, and you can do imaging and scoping to get a look at the surface of your intestine, to see if it looks functional. The scoping is invasive, and the imaging is expensive, so you probably don't need to do it unless you think your leanness is a problem. If you're just a light eater, have good energy levels and show no signs of nutritional deficiencies, that could be all the explanation you need. There are those who say that a calorie restricted diet is THE MOST healthy way to go, and the way to live the longest.
