Theses fats are also good for you and do not have an effect on cholesterol levels. Polyunsaturated fats are high in omega-3 fatty acids which cannot be produced naturally by the body. They instead are essential and must be taken by the body through diet or supplementation. They help your body prevent fat storage and speed up muscle recovery. Also, polyunsaturated fats have Omega-6 in them. This is another essential fatty acid which is good for muscle recovery and a good anti-inflammatory for after a workout.
How to Obtain these Fats:
These fats are found in fish oils, flaxseed oils and vegetable oils; such as corn, cottonseed, safflower, soybean and sunflower oil. Taking Omega-3 fatty acids either through an oil, pill or as a salad dressing are typically ways in which these fatty acids can be consumed. Omega-6 is found in eggs, poultry, margarine and vegetable oil so there is no real need to take it as a supplement unless you do not consume those foods regularly.
