New research shows that eating a handful of walnuts a day provides immediately protection against heart disease. Eating them regularly will greatly decrease the risk and provide permanent protection from heart disease. The research also shows a significant improvement in cholesterol levels and flexibility of blood vessels, which is vital for healthful blood flow, just 4 hours after people ate nuts or nut oil.

We should all be including walnuts in our diets because regular consumption protects against many types of cardiovascular disease due to their effect on serum cardiovascular risk factors.

“And only by consuming a handful of walnuts or walnut oil for four days in a week you can significantly reduce the risk of heart disease,” said Dr. Penny Kris Eterton, professor of nutrition at Penn State University in Pennsylvania.

In this study, they specifically identified the portion you need to eat daily in order to achieve better health. Eating only three tablespoons (51 g) of walnut oil you can improve the condition of your blood vessels in 4 hours.

Walnuts oil is especially good for the integrity of endothelial cells. These cells are in line with the blood veins and play a significant role in their elasticity.
