Which of the following is considered a good source of complex carbohydrates?

Beans are considered a good source of complex carbohydrates due to their high fiber content and low glycemic index. Complex carbohydrates consist of longer chains of sugar molecules, which means they take more time for the body to break down and digest. This results in a more gradual release of energy, helping to maintain stable blood sugar levels.

Beans not only provide essential energy but also come packed with protein, vitamins, and minerals. Their high fiber content is particularly beneficial for digestive health, as it aids in maintaining bowel regularity and can help lower cholesterol levels. Furthermore, beans are nutrient-dense, meaning they offer more vitamins and minerals relative to their caloric content, making them an excellent choice for a balanced diet.

In contrast, while rice and potatoes can be good sources of carbohydrates, they may not offer the same level of fiber and diverse nutrients as beans. White bread, on the other hand, typically contains refined carbohydrates that lack the fiber and nutrients found in more whole food sources like beans. This makes beans a superior option for complex carbohydrates, contributing not only to energy needs but also to overall health.
