olive, canola, and sesame oils
avocado
nuts, such as almonds, cashews, and pistachios; peanuts and peanut butter
Polyunsaturated fat is prevalent in:
corn, cottonseed, and safflower oils
sunflower seeds and sunflower oil
flaxseed and flaxseed oil
soybeans and soybean oil

The Facts on Omega-3 Fats
When it comes to good-for-you fat, seafood stands out. Seafood harbors omega-3 fats called DHA (docosahexanoic acid) and EPA (eicosapentanoic acid), unsaturated fats considered central to a child's brain development and eyesight, and for heart health.
Omega-3 fats are linked to lower levels of blood triglycerides (fats), reduced risk of clots that block the flow of blood to the heart and brain, and a normal heart beat, among other benefits.
Seafood contains preformed omega-3 fats, the type the body prefers. Adults and children can make DHA and EPA from the essential fat alpha-linolenic acid, found in foods such as walnuts and flax, but experts say less than 10% is actually converted. Fatty, cold-water fish, such as salmon, sardines, and tuna are rich in preformed omega-3s.
