14 Jan 2019 --- Higher intake levels of dietary fiber and whole grains are being linked with a lower risk of non-communicable diseases, body weight and cholesterol levels, according to an extensive analysis published in The Lancet. The research highlights the importance of carbohydrate quality in our diets, which may be particularly salient as low carb diets continue to trend. “We understood fiber to be good for us, but we didn't realize just how good it is,” study author, Andrew Reynolds of the University of Otago, New Zealand, tells NutritionInsight.
