Whole Grain Rye May Improve Cholesterol

Rye, the principal grain consumed in traditional Scandinavian diets, is a fiber-rich food associated with satiety, weight management, and blood sugar control. In a European study, 158 people were assigned to either a standard Nordic diet (with lots of refined grains) or a healthy Nordic diet (rich in whole grains, fruits, vegetables, and low fat dairy) consuming their usual calorie level. Whole grain wheat and rye intake was verified using blood biomarkers. Researchers found that a high intake of whole grain rye (as measured using a plasma biomarker) was associated with decreased LDL (“bad” cholesterol), and an improved LDL to HDL ratio, while the biomarker for whole wheat consumption was not associated with any change in cholesterol.
