If you could have a gigantic billboard anywhere with anything on it, what would it say and why?
My message would be: “Sugar is toxic.” Sugar and other
natural or artificial sweeteners are among the most addictive agents in our
environment. When consumed in quantities that exceed the rate of metabolism in
muscle or the brain, sugar is converted to fat, resulting in insulin
resistance, obesity, and an increased risk of many other diseases, including
cancers. While consuming fats and proteins evokes a feeling of satiety,
consuming sugars induces a desire for more sugar within an hour or so. We
evolved this addiction because, in the not-so-distant past, adding fat to our
bodies at the end of a growing season when fruits were ripe was essential for
surviving until the next growing season. But today, sugar is available all year
round and is one of the cheapest foods available. So we continually add fat to
our bodies. We may be approaching a time when sugar is responsible for more
early deaths in America than cigarette smoking. I have written and lectured
extensively on this subject over the past ten years as our understanding
of the biochemical basis for the toxicity of sugar, especially the link to
cancer, has become more clear.
