Polyunsaturated fatty acids
Polyunsaturated fatty acids (PUFAs) are a type of healthy fat found in foods like fish, walnuts, and plant oils. They contain multiple double bonds in their chemical structure, which makes them liquid at room temperature. PUFAs are essential for your body because they support brain function, reduce inflammation, and help maintain healthy cell membranes. Since your body can't produce them, you need to get PUFAs through your diet. The most common types are omega-3 and omega-6 fatty acids, both important for overall health when consumed in balanced amounts.
