Meat and fish lead this ranking because animal tissue concentrates niacin from the protein it contains. Your body converts some amino acids directly into niacin during digestion, so foods high in protein tend toward high niacin density. This mechanism explains why the table below reads as it does.
Niacin also occurs naturally in grains, legumes, and nuts, though often in a form your body cannot access without processing. The ranking captures what your small intestine can actually use. Bear in mind that the position of a food here reflects its niacin per 100 g, not how much you would typically eat at one time.
