Sugar: The Bitter Truth
Fructose is a toxin like alcohol, but you don't even get a buzz from the high. This is a 1.5 hour long lecture and it has quite a bit of biochemistry. The take home lesson is
1. There's so much sugar in soft drinks to cover up the taste of the salt. The elevated salt is to make the drinker thirstier.
2. Fructose stimulates lipid biosynthesis in the liver.
3. Fructose turns off hepatic insulin signal recognition which leads to Type II diabetes.
4. These fructose effects lead to more hypertension and cardiovascular disease from increased fat.
The solution is drink more water, eat more fiber, and exercise more to change your liver metabolism. Exercise will not burn enough fat, but it prevents the fat from being made from the fructose.
