Which is the best source of complex carbohydrates?

Whole-grain bread is considered the best source of complex carbohydrates because it is made from grains that contain all parts of the grain kernel, including the bran, germ, and endosperm. This means it retains the natural fiber and nutrients that are beneficial for health. Complex carbohydrates are digested more slowly than simple carbohydrates, providing a steady release of energy and helping to maintain stable blood sugar levels. Whole grains also promote digestive health and can contribute to a reduced risk of various chronic diseases.

In contrast, fish and red meat primarily provide protein and fats rather than carbohydrates. While vegetables do contain carbohydrates, they tend to be lower in complex carbohydrates compared to whole grains and often do not provide as much energy. This makes whole-grain bread the most suitable option for those seeking complex carbohydrates in their diet.
