Which vitamin is linked to lowering LDL and raising HDL cholesterol and is commonly consumed in meats, poultry, fish, and whole grains?

Explanation:
Niacin, a B vitamin, is known for its favorable effect on cholesterol: it can lower LDL (bad) cholesterol and raise HDL (good) cholesterol. This lipid-changing action comes from its influence on liver production and processing of lipoproteins. Dietary sources include meats, poultry, fish, and whole grains, which is why this vitamin is commonly consumed in those foods. The other vitamins listed have different primary roles—pantothenic acid is involved in CoA-dependent energy metabolism, biotin supports carboxylation reactions, and folate is key for DNA synthesis and homocysteine metabolism—so they aren’t linked to lowering LDL and raising HDL in the same way.
