Walnut against heart diseases

Danish researchers are far-reaching in conclusions, saying the whole walnut kernel, rather than its individual nutrients have resulted in vascular protection effects.

People at an increased risk of heart disease, such as regular smokers, those with high blood cholesterol, diabetes, cases of high blood pressure or with obesity, suffer from the fact that arteries do not expand enough when necessary, e.g. during exercise, mental stress, etc. Decreased elasticity of the arteries is due to impaired endothelial function.

U.S. scientists from Harvard reported in the Journal of the American Medical Association found that regular consumption of walnuts (or almonds) reduces the risk of type 2 diabetes.

Studying a large group of women, researchers found that those who consumed about 150 g walnuts per week (about 20 grams or four walnuts a day) had a 27 percent lower risk of diabetes.

Health effect of walnuts is probably due to the overall composition. They improve the regulation of blood glucose and increase insulin secretion, but it has not yet been fully understood how this effect is achieved.. Walnuts protect against cardiovascular disease and type 2 diabetes due to cholesterol lowering capability.

Meanwhile scientists warn that, like all nuts, walnuts are also high in calories (energy). Therefore, it should not be added to food, but should replace in the daily menu some of sources of saturated (mostly animal) fats and calories, such as meat, butter, high fat cheese, white bread, white rice, corn flakes, ready confectionery products with high technological content of hydrogenated (saturated) fat.
