Document Summary
You absorb it better when you eat it with fat. It"s absorbed in the intestines with fat in micelles. Your body stores vitamin e in fat cells (adipose tissue) Alpha-tocopherol: the form of vitamin e absorbed by the human body. A fat soluble antioxidant: works in lipid environments. Some fatty acids are oxidized more easily than others. The more unsaturated that fat is, the easier the oxidation reaction (pufas are trouble!) Saturated fats/trans fats have a longer shelf life. Frying in oil with high heat can smell bad. The more antioxidants you need to protect those fats from oxidation. Luckily the foods that contain pufa also contain vitamin e. Food sources of unsaturated fats have tons of vitamin e! Uncooked oils contain the most vitamin e (salad dressings, margarine) Frying in oil kills almost all the vitamin e. Uncommon and only happens with supplements, not with food. Doses would have to be huge (over 50x the rda: nausea, upset stomach.
