Which of the following is likely to be the best source of fiber?

Legumes are an excellent source of fiber, making them the best choice among the options provided. They contain both soluble and insoluble fiber, which contributes to digestive health, helps regulate blood sugar levels, and supports cardiovascular health. Additionally, legumes are rich in protein and various essential nutrients, making them a nutritious option for anyone looking to increase their fiber intake.

While green vegetables, oatmeal, and wheat-containing cereals also provide fiber, legumes typically have a higher fiber content per serving. Green veggies offer many health benefits and are high in various vitamins and minerals, but their fiber content is generally lower compared to legumes. Oatmeal is a good source of soluble fiber, especially beta-glucans, which can help lower cholesterol levels, while wheat-containing cereals can provide both types of fiber but often contain added sugars and other fillers.

Thus, for a concentrated source of dietary fiber, legumes stand out as a particularly beneficial option.
