Question

Quizplus · Accepted Answer

Meat, particularly liver and muscle meats, have the highest availability of niacin for absorption. Plant-based sources of niacin, such as cereal grains and enriched bread products, have lower bioavailability due to the presence of compounds that inhibit absorption. Ready-to-eat cereals can vary in their bioavailability depending on fortification levels and other factors.
