Which type of food is known to be high in omega-3 fatty acids?

The type of food known to be high in omega-3 fatty acids is fish. Omega-3 fatty acids are essential fats that the body cannot produce on its own, meaning they must be obtained through diet. Fish, particularly fatty species like salmon, mackerel, sardines, and trout, are well-known sources of omega-3 fatty acids, specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fatty acids are beneficial for heart health, brain function, and reducing inflammation in the body.

Other food types listed in the options do not provide significant amounts of omega-3 fatty acids. While red meat may contain some omega-3, the levels are comparatively lower than those found in fish. Leafy greens contain a different type of omega-3 called alpha-linolenic acid (ALA), but they do not match the concentrations found in fish. Cereal grains typically lack omega-3 fatty acids entirely or provide negligible amounts. Thus, fish stands out as the most rich source for these important nutrients.
