Is Sugar a Toxin?
A lengthy article posted in The New York Times April 13, 2011 gives compelling evidence that sugar, specifically fructose (high fructose corn syrup) increases the likelihood of obesity, diabetes, metabolic syndrome and cancers in humans. In a viral YouTube Video Robert Lustig presents his case for chronic diseases and their link to overt sugar consumption in the United States and elsewhere. Dr. Lustig is a pediatric specialist and makes a persuasive case that sugar, specifically high-fructose corn syrup found in soda and fruit juice is a "toxin" or "poison".
The number of American diabetic or obese --termed "diabesity"--has skyrocketed in the last 30 years and, if Lustig is right, it would mean under-exercising, overeating of all foods, and overt consumption of sugar is the likely dietary cause of several chronic ailments namely: heart disease, hypertension and many common cancers.
100 calories of glucose (from potato or bread or other starch) is metabolized differently than 100 calories of sugar (half glucose half fructose). The fructose component of sugar and high fructose corn syrup are metabolized primarily by the liver and glucose from sugar and starches is metabolized by every cell in the body. Consuming sugar (glucose and fructose) means more work for the liver than if you consumed the same number of calories of starch (glucose). In laboratory studies, it's clear that if fructose hits the liver at sufficient speed and quantity, the liver will convert much of it to fat, inducing a condition known as insulin resistance, considered to be a fundamental problem in diabetes, and may also be the underlying defect in many cancers.
The Department of Agriculture analysts and the USDA estimates that consumption of these 'added sugars' has increased from 40 pounds per person per year (that's a can and a half of coca-cola per day of sugar) to 90 pounds per person per year. That's a lot of sugar! The consumption happens to coincide with current epidemics of obesity and diabetes. Maybe this is circumstantial evidence, but it's compelling nonetheless.
