What is the primary source of starch in the diet?

The primary source of starch in the diet is grains. Grains, such as rice, wheat, corn, and oats, are rich in carbohydrates and serve as a staple food for many cultures around the world. They are composed mainly of starch, which is a complex carbohydrate that the body breaks down into glucose for energy.

In addition to providing energy, grains also offer various nutrients, including fiber, B vitamins, and minerals, making them an essential part of a balanced diet. While vegetables and some fruits do contain starch, they typically have lower concentrations compared to grains. Dairy products, on the other hand, primarily provide proteins and fats rather than starch. Therefore, grains are recognized as the most significant source of dietary starch.
