Government Sugar Quotas Increase Demand for Harder-to-Metabolize Corn Syrup, Making Americans Fatter

For decades on the last day of every micro principles class I discussed the causes and effects of U.S. government sugar quotas. Government sugar quotas reduce the quantity of sugar that can be imported into the U.S., increasing the price of sugar. If the price of one substitute (sugar) rises, the demand for the other substitute (corn syrup) increases. As a result Americans consume more corn syrup which is harder to metabolize and easier to overconsume. Government sugar quota regulation thus increases obesity, and obesity-related diseases such as diabetes, heart disease, and cancer.

(p. D5) To clarify the effects of our high-sugar diet, I consulted an expert, Kimber L. Stanhope, a researcher in nutritional biology at the University of California, Davis, whose work is free of industry support and funded primarily by the National Institutes of Health. In a comprehensive 34-page review of research published in Critical Reviews in Clinical Laboratory Sciences in 2016, she linked consumption of added sugar to metabolic disease — cardiovascular disease, Type 2 diabetes and nonalcoholic fatty liver disease — as well as high blood levels of uric acid, a risk factor for kidney stones and gout.

In studies done in her lab among young adults consuming their normal diets, the risk for developing heart disease and kidney stones rose in direct proportion to the amount of high-fructose corn syrup they consumed.

. . .

“Fructose and glucose are not metabolized the same way in the human body,” which can account for the adverse effects of fructose, Dr. Stanhope said. Glucose is metabolized in cells throughout the body and used for energy. Fructose is metabolized in the liver, resulting in fat production and raising the risk of heart and fatty-liver disease. In addition, she explained, “fructose doesn’t stimulate the satiety-promoting substance leptin,” prompting some people to overconsume it, especially in soft drinks containing high-fructose corn syrup, and other tempting foods as well.
