The Study
Intake of Refined Carbohydrates and Whole Grain Foods in Relation to Risk of Type 2 Diabetes Mellitus and Coronary Heart Disease
This study doesn’t do any new experiments — it just talks about what other studies might have found. So we can’t say whole grains definitely prevent disease, only that some people think they might be linked to being healthier.
Analysis score

Where the score came from
Eating whole grains like brown rice or whole wheat bread may help keep your heart and blood sugar healthy, but eating white bread or sugary cereals doesn't give you the same help.
