Niacin (Vitamin B3) is found in which foods?

• A. Meats, fish, poultry, beans, peanuts, grains
• B. Dairy
• C. Leafy greens
• D. Fruits

Answer: (A)

Niacin (B3) is found in a broad range of foods, with the most reliable sources coming from both animal products and certain plant foods. It’s used by the body in energy metabolism, in the form of NAD and NADP. Foods like meats, fish, and poultry supply niacin in a form the body can readily use. Plant sources such as beans and peanuts also provide substantial amounts, and grains—especially when fortified—contribute a significant amount as well. Dairy, leafy greens, and fruits contain only small amounts in comparison, so they are not primary sources of niacin. Fortified cereals and grain products further boost intake. So the best answer includes meats, fish, poultry, beans, peanuts, and grains.
