Switching to Whole Grains Can Improve Cholesterol, Blood Sugar Control, and Inflammation

Randomized controlled trials are the “gold standard” of nutrition research as they can be used to establish cause and effect. In this article, researchers analyzed more than 20 randomized controlled trials to see how replacing refined grains with whole grains can impact health. They found that for adults both with and without risk factors of heart disease, substituting whole grains for refined can improve total cholesterol, LDL (“bad”) cholesterol, hemoglobin A1c (a measure of blood sugar control), and C-reactive protein (a measure of inflammation).
