"Healthy fats" like omega-3 fatty acids may help your heart. Lowering your triglycerides is one of the main advantages. Particular forms of omega-3s include ALA (found in plants) and DHA and EPA (found in seafood). You may increase the amount of omega-3s in your diet by consuming foods like flaxseed, chia seeds, and fatty seafood (such as salmon and mackerel).
