Which food group is considered the best source of carbohydrates?

Grains are considered the best source of carbohydrates due to their composition and abundance of complex carbohydrates. Grains such as rice, wheat, oats, and barley are rich in starches, which provide a sustained energy source for the body. They also contain dietary fiber, B vitamins, and essential minerals like iron and magnesium.

While other food groups, such as fruits and vegetables, do contain carbohydrates, they primarily provide simple sugars and fiber rather than the complex carbohydrates present in grains. Dairy also contains carbohydrates, mainly in the form of lactose, but it is not as concentrated in carbohydrates as grains. Thus, when looking for a food group that is particularly high in carbohydrates, grains are the most prominent and beneficial option.
