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).
