Common Traits of Traditional Diets
- Traditional diets universally contain rich sources of fat-soluble vitamins like K2, A, and D from animal-derived foods.
- They avoid processed sugars and flours, de-emphasize muscle meats, and combine both plant and animal foods.
Genetics Influence Starch Digestion
- AMY1 gene copy number varies and influences how well individuals digest starch through salivary amylase.
- Populations with starch-rich ancestors tend to have more AMY1 copies, allowing better starch metabolism.
APOE Gene and Fat Metabolism
- APOE gene variants affect lipid metabolism and response to saturated fat.
- APOE4 carriers may experience LDL cholesterol spikes on high saturated fat diets and have increased Alzheimer's risk.
