Whole grains provide a rich source of nutrients, including fiber, vitamins, and minerals, compared to refined grains, which have been stripped of most of their beneficial elements. The primary benefit of consuming whole grains is their positive impact on digestive health, as the high fiber content promotes regularity and aids in preventing constipation. Additionally, whole grains have a lower glycemic index, leading to more stable blood sugar levels, which enhances sustained energy and supports weight management.
