Which food is particularly rich in vitamin B?

Wheat germ flour is particularly rich in vitamin B because it contains various B vitamins that play crucial roles in energy metabolism and the function of the nervous system. Specifically, it is a good source of thiamine (B1), riboflavin (B2), niacin (B3), and folate (B9). These vitamins are essential for converting carbohydrates into glucose, supporting brain function, and promoting healthy cell metabolism.

In contrast, while carrots, chicken breast, and apples provide certain nutrients, they do not have the same concentration or variety of B vitamins as wheat germ flour. Carrots are known for their high vitamin A content, chicken breast is a good source of protein and B3 (niacin), and apples primarily provide fiber and vitamin C but are not significant sources of the B vitamin group. Thus, wheat germ flour stands out as the superior source of vitamin B among the options given.
