Polyunsaturated fats

Fat is a major source of energy and helps your body absorb vitamins. It is also important for proper growth, and for keeping you healthy. The main types of “healthy” fats are monounsaturated and polyunsaturated.

Chemically, polyunsaturated fats belong to the class of simple lipids, as they are fatty acids with two or more double bonds in cis configuration.

Linoleic acid (n-6) (LA) and alpha-linolenic acid (n-3) (LNA) are two of the main representative compounds, known as dietary essential fatty acids (EFA) because they prevent deficiency symptoms and cannot be synthesized by humans.

Essential fats play a role in many body processes, including immune and nervous system function, blood clotting, and blood pressure regulation.

Polyunsaturated fats – found mainly in vegetable oils like corn, sunflower, safflower and soybean. They also can be found in fish (such as herring, mackerel, salmon, trout, and tuna), mayonnaise and oil-based salad dressings
