Which foods are good sources of B vitamins?

• A. Dairy, poultry, fish, nuts, eggs, lean meat, cereals, and leafy greens
• B. Apples, oranges, grapes, bananas
• C. Meatless diets like vegetables only
• D. Rice, corn, wheat, barley

Answer: (A)

B vitamins come from a wide range of foods, especially animal products, fortified grains, leafy greens, nuts, and eggs. They are water-soluble vitamins that support energy metabolism, red blood cell formation, and nervous system function, and they need regular intake because the body doesn’t store them in large amounts.

The foods listed cover multiple B vitamins across different categories: dairy and eggs provide riboflavin (B2) and B12; poultry, fish, and lean meat supply B12 and niacin (B3), with some B6 present in animal foods as well; cereals are often fortified with several B vitamins (including thiamin B1, riboflavin B2, niacin B3, folic acid B9, and sometimes B12); leafy greens are rich in folate (B9); nuts contribute various B vitamins like niacin and B6. This broad mix ensures coverage of the common B vitamins.

Fruits shown in the other options don’t offer reliable amounts of B vitamins. A meatless diet of vegetables lacks B12 unless fortified or supplemented, and grains by themselves (especially if not fortified) don’t reliably supply the full spectrum of B vitamins. That makes the combination including dairy, poultry, fish, nuts, eggs, lean meat, cereals, and leafy greens the best source set for B vitamins.
