Grains Protect Against Heart Disease

October 21, 2016

Consumption of both refined and whole grains helped reduce weight, blood pressure, and total and LDL cholesterol among overweight and obese patients, according to a study published in the Journal of Nutrition. Researchers compared heart disease risk factors in 40 participants on either a whole-grain diet, including rice, wheat, and oats, or a refined-grain diet. While both groups saw health improvements, decreased diastolic blood pressure was three times greater in the whole-grain group, compared to the refined-grain group. Researchers suspect similar dietary interventions may prove effective for hypertension prevention and lower mortality risks for heart disease.
