5. Omega-3 Fatty Acid
Omega-3 fatty acids that are found in oily fish, such as salmon, scomber, tuna, herring, are known to be good at regulating metabolic processes. This acid is not naturally produced by the human body, that’s why we should eat some certain products to provide our organism with omega-3. If you allergic to fish and cannot eat it, take special omega-3 supplement instead.
