Grains and cereals are the foundation of diets worldwide, providing essential nutrients, energy, and a versatile base for countless dishes. As a staple food group, they are celebrated for their ability to nourish populations, adapt to diverse cuisines, and offer significant health benefits.
Grains include whole varieties like wheat, rice, barley, oats, millet, and quinoa, as well as refined options like white rice and all-purpose flour. Whole grains are particularly valued for their high fiber content, which aids digestion and supports heart health. They are also rich in vitamins, minerals, and antioxidants that promote overall well-being. Refined grains, while less nutrient-dense, are often fortified to replace some of the lost nutrients.
Cereals, derived from grains, play an integral role in meals around the world, from breakfast favorites like oatmeal and cornflakes to side dishes like pilafs and risottos. Many cereals are gluten-free, making them accessible to those with dietary restrictions, such as rice, quinoa, and millet.
