How many grams of carbohydrates can be found in a single serving of beans?

In the context of beans and their carbohydrate content, the correct answer reflects that there is a range of carbohydrate amounts depending on various factors such as the type of bean and serving size. Beans are known for their complex carbohydrates, which provide a good source of energy, dietary fiber, and nutrients.

The variability in carbohydrate content is why the answer includes all the previously mentioned choices. While some types of beans, like black beans or kidney beans, may fall within the 10-15 gram range for a smaller serving size, others may have higher carbohydrate content, reaching 30-45 grams in larger servings.

Furthermore, specific varieties of beans can have different nutritional profiles. For example, lentils or chickpeas might also fit within these categories, demonstrating that beans as a food group can yield a carbohydrate content within the specified ranges, thereby validating the answer encompassing all options listed. This nuanced understanding is key to recognizing the versatility of beans within a balanced diet.
