Document Summary

Fructose has a low glycemic index: doesn"t vary blood sugar as much. Small amounts is okay, but today diet can include ~10% fructose. Processed in the liver too much = fats, glucose = glycogen which is regulated by insulin. Inc fat in blood, too much fat in blood = heart disease. Cohort study: high fructose drinks = inc risk of gout uric aid crystallizes and accumulates in joints (usually linked to too much meat eating) 1 serving per day had a 74% higher risk, 2+ servings 240%, though diet drinks were not associated at all, out of 100 people having soda 2 will get gout. Mechanism: fructose uric acid, glucose doesn"t follow this path. Sucrose issue: splits to fructose and glucose = glycation. Proteins amine end of amino acid + sugar"s aldehyde (reducing sugar) = maillard reaction amadori product which can reduce further = protein-sugar- protein.
