POLYUNSATURATED FATS

Polyunsaturated fats are generally oils at room temperature. They are found in nuts and grains and are extracted from seeds, such as sunflower, soya bean, cottonseed, maize (corn),sesame and grape seed.
Oily fish (herring, salmon, tuna, mackerel and sardines) and seafood contain highly polyunsaturated fats, known as omega-3 fatty acids.
Polyunsaturated fats lessen the fatty build-up on artery walls and reduce cholesterol in the blood. But we need a little, not huge quantities.
