When it comes to fat, there’s one type you don’t want to cut back on, omega-3 fatty acids. Two crucial ones — EPA and DHA — are primarily found in certain fish. ALA (alpha-linolenic acid), another omega-3 fatty acid, is found in plant sources such as nuts and seeds. Not only our body needs these fatty acids to function, but also they deliver some big health benefits. Omega-3 fatty acids are considered essential fatty acids: They are necessary for human health but the body can’t make them, we have to get them through food. Omega-3 fatty acids can be found in fish like, salmon, tuna, and halibut, other seafood including algae and krill, some plants, and nut oils. Also known as polyunsaturated fatty acids (PUFAs), omega-3 fatty acids play a crucial role in brain function, as well as normal growth and development. They have also become popular because they may reduce the risk of heart disease.
