Dietary fat: Know which to choose

Fats and health

Fat is a healthy part of the diet when it's balanced with carbohydrates, protein and the needs of your body. Your age, sex, activity level, and if you're pregnant or breastfeeding can change the amount of fat and other nutrients you need.

Two fatty acids, the omega-6 linoleic acid and the omega-3 alpha-linolenic acid (ALA), are needed for the body but must come from the diet. You can find ALA and linoleic acid in walnuts, flaxseed, chia seed and soybean products.

Some experts suggest that in a healthy diet, no more than about 30% of calories should come from fat.
