Grain-based foods are products made primarily from grains like wheat, rice, corn, and oats. These grains are often ground into flour or processed into other forms, such as cereal or pasta. Grain-based foods are a staple in many diets around the world, providing essential carbohydrates, fiber, and nutrients. Many popular dishes are grain-based, including bread, pizza, and porridge. Whole grains, which include the entire grain kernel, are especially nutritious and can help with digestion and heart health. Incorporating a variety of grain-based foods into your meals can contribute to a balanced and healthy diet.
