Whole grain refers to grains that contain all three parts of the grain kernel: the bran, germ, and endosperm. This means that whole grains retain their natural nutrients, including fiber, vitamins, and minerals, making them a healthier choice compared to refined grains, which have been processed to remove the bran and germ. Common examples of whole grains include brown rice, quinoa, oats, and whole wheat. Incorporating whole grains into your diet can support digestive health, help maintain a healthy weight, and reduce the risk of chronic diseases such as heart disease and diabetes.
