We have an "epidemic" of obesity. It can't be that our genetics have changed in three decades to account for it. It can't be that we're suddenly lazy, for there is now an epidemic of obese six-month olds. We exercise more, and yet we're fat. We eat in moderation, and yet we're fat. Why? It's what we eat. The food industry has changed it, and the government has gone along. For instance, they have filled soda with salt. But we do not taste that salt. They cover it with sugar (14 teaspoons worth). The average American is now secretly being fed 141 pounds of sugar, which has been denatured and made into a toxin on purpose. Our leptin (the satiety hormone) systems have been disrupted. We have been deprived of good fats (unadulterated, raw, and unprocessed) and been stuffed with carbohydrates, in liquid form and as fluffy starch. It all adds up to a compelling talk: "Sugar: The Bitter Truth."
(UC Television) Robert H. Lustig, MD, University of California San Francisco Professor of Pediatrics in the Division of Endocrinology explores the damage caused by sugary foods. He argues that fructose (too much) and fiber (not enough) appear to be cornerstones of the obesity epidemic through their effects on insulin.
