Dr Friedlander discusses the best forms of protein, fats, carbohydrates, exercise and nutrients that support positive epigenetic factors and longevity. Proteins high in the amino acids proline, lysine, glycine and alanine have shown in studies to extend life span, support repair, wound healing, immune function, thyroid, bone density, skin and arteries. Reducing intake of inflammatory proteins such as tryptophan, methionine and cysteine (typically found in lean meats, chicken and whey protein) extends life span as well. Fat laden grass fed meats are better Reducing polyunsaturated fats such as corn oil, safl ower, sun ower, and canola is important, as these oils lead to aging, via the mechanisms of glycation (bonding of a protein or lipid molecule to sugar molecule). Glycation results in a loss of artery elasticity, aging skin and damage to DNA and mitochondria. Dr. Friedlander discusses methylene blue and collagen as and life style choices that promote longevity.
