20 WWI and II James Neel, Anthropologist, with Yanomamö Indian, 1978 Am J Hum Genetics 1962; 14: Fructose is in added sugars, including sucrose and high fructose corn syrup Fructose induces metabolic syndrome in animals. These effects can even be observed with caloric restriction Fructose causes metabolic syndrome due to its ability to cause ATP depletion, uric acid generation, and mitochondrial dysfunction A mutation in uricase led to higher uric acid levels that increase our sensitivity to fructose and sugar The marked increase in sugar and HFCS was the perfect storm for making us obese and diabetic IN CONCLUSION: EXCESSIVE INTAKE OF FRUCTOSE HAS A MAJOR ROLE IN THE OBESITY EPIDEMIC
