Barry M. Popkin, Ph.D., Professor, Department of Nutrition, University of North Carolina at Chapel Hill, has published widely on the dangers of sugar-sweetened drinks and their contribution to the obesity epidemic. In a review of HFCS in the American Journal of Clinical Nutrition,(ii)he explains the mechanism by which the free fructose may contribute to obesity.He states that: “The digestion, absorption, and metabolism of fructose differ from those of glucose. Hepatic metabolism of fructose favors de novo lipogenesis (production of fat in the liver). In addition, unlike glucose, fructose does not stimulate insulin secretion or enhance leptin production. Because insulin and leptin act as key afferent signals in the regulation of food intake and body weight (to control appetite), this suggests that dietary fructose may contribute to increased energy intake and weight gain. Furthermore, calorically sweetened beverages may enhance caloric over-consumption.”He states that HFCS is absorbed more rapidly than regular sugar and that it doesn’t stimulate insulin or leptin production. This prevents you from triggering the body’s signals for being full and may lead to over-consumption of total calories. He concludes by saying that:“… the increase in consumption of HFCS has a temporal relation to the epidemic of obesity, and the overconsumption of HFCS in calorically sweetened beverages may play a role in the epidemic of obesity.”The corn industry takes his comments out of context to support their position. “All sugar you eat is the same.”

True pharmacologic doses of any kind of sugar are harmful, but the biochemistry of different kinds of sugar and their respective effects on absorption, appetite, and metabolism are different, and Dr. Popkin knows that.

David S. Ludwig, M.D., Ph.D., Associate Professor of Pediatrics, Harvard Medical School, and a personal friend, has published extensively on the dangers and the obesogenic properties of sugar-sweetened beverages.

He was quoted as saying that “high fructose corn syrup is one of the most misunderstood products in the food industry.” When I asked him why he supported the corn industry, he told me he didn’t and that his comments were taken totally out of context.

Misrepresenting science is one thing, misrepresenting scientists who have been at the forefront of the fight against obesity and high fructose sugar sweetened beverages is quite another.

HFCS is almost always a marker of poor-quality, nutrient-poor disease-creating industrial food products or “food-like substances”. The last reason to avoid products that contain HFCS is that they are a marker for poor-quality, nutritionally-depleted, processed industrial food full of empty calories and artificial ingredients. If you find “high fructose corn syrup” on the label you can be sure it is not a whole, real, fresh food full of fiber, vitamins, minerals, phytonutrients, and antioxidants. Stay away if you want to stay healthy. We still must reduce our overall consumption of sugar, but with this one simple dietary change you can radically reduce your health risks and improve your health.While debate may rage about the biochemistry and physiology of cane sugar versus corn sugar, this is in fact beside the point (despite the finer points of my scientific analysis above). The conversation has been diverted to a simple assertion that cane sugar and corn sugar are not different.

The real issues are only two.

1. We are consuming HFCS and sugar in pharmacologic quantities never before experienced in human history–140 pounds a year versus 20 teaspoons a year 10,000 years ago.
