Document Summary
Amdr for omega-6: 5%-10% of energy: about 11-22 grams/day, we meet amdr (salad dressings, vegetable oils, margarine, mayonnaise) Amdr for omega-3: 0. 6%-1. 2: about 1. 3-2. 6 grams/day, we do not meet amdr, fish, shrimp, canola oil, walnuts, flaxseed, novel sources (omega-3 eggs, omega-3 milk, etc) Ideal breakdown: saturated fat: <7, trans fat: absolute minimum , polyunsaturated: What about monounsaturated fat: about 10% of energy. They have low ldl-cholesterol: because they displace saturated fat from diet. Are hdl-cholesterol neutral (vs. trans fats which decrease hdl) A reminder of food sources: olive oil, canola oil, cashews. Butter and margarine contain same amount of energy and fat. How they differ is in the type of fat: butter contains primarily saturated fat, non-hydrated margarine contains polyunsaturated fat. Result of this difference: different effects of ldl-cholesterol. She said to take a look at it** Little effect on blood cholesterol: a high intake means we decrease our own internal production (saturated and trans fats increase blood cholesterol)
