What are Oats?
Oats are edible cereal grains harvested from the oat plant (Avena sativa). They belong to the grass family and are cultivated primarily for human consumption and animal feed.
Unlike many refined grains, oats are usually consumed as whole grains, meaning they retain their bran, germ, and endosperm. This helps preserve their nutritional value and fiber content.
Oats are commonly processed into different forms such as steel-cut oats, rolled oats, quick oats, and oat flour. Despite processing differences, they remain one of the most nutrient-dense grains available.
