Good news for overweight adults who are prone to getting cardiovascular diseases and diabetes. Eat walnuts or walnut-enriched diet.
A study at Yale University separated 46 adults between 30 and 75 years old with BMI (Body Mass Index) more than 25 and waist circumference more than 102 cm for men and 89cm for women into 2 groups. All has risk factors for metabolic syndrome, a precursor of diabetes and heart diseases with none of them being smokers. The study was led by Dr. David Katz.
The first group were assigned to a walnut-enriched ad libitum diet while the second group were assigned to an ad libitum diet without walnuts.
It was found that none of the first group on walnut rich diet gained weight and had improved endothelial function and improved BMI plus a smaller waist. Endothelial cells line the blood vessels, help with blood clotting and new blood cells creation plus control blood pressure. The group also has a 45% lower mortality risk.
