Polyunsaturated fatty acids (PUFAs) are a type of fat found in various foods that are essential for human health. They contain multiple double bonds in their chemical structure, which distinguishes them from saturated and monounsaturated fats. PUFAs are important for brain function, cell growth, and overall health. Common sources include fish, nuts, seeds, and vegetable oils. There are two main types of PUFAs: omega-3 and omega-6 fatty acids. Omega-3 fatty acids are known for their anti-inflammatory properties and are found in fatty fish like salmon and in flaxseeds. Omega-6 fatty acids are more prevalent in many cooking oils, such as corn and soybean oil, and play a role in various bodily functions.
