Eating walnuts is one of the very best ways to keep your heart and cardiovascular system healthy. The nut raises levels of the HDL ‘good’ cholesterol, and its oil helps maintain strong blood vessels.
People with cardiovascular disease should take a sip of walnut oil after meals, say researchers from Penn State University, and everyone should eat a few walnuts every day.
They reckon that people who start eating the nuts and drinking the oil will dramatically reduce their chances of heart attack and cardiovascular disease, the number one killer in the West.
Although it’s known that whole walnuts reduce cholesterol levels, the Penn State researchers discovered why it’s so beneficial, and the importance that the walnut oil also plays.
They gave 85 grams of nuts and 51 grams of walnut oil to 15 people with raised cholesterol levels. Within 30 minutes—and for up to six hours afterwards—the nuts and oils raised HDL ‘good’ cholesterol levels, and the oil was especially good for the health of blood vessels after a meal.
