Question: What is the Best Nut?
Answer: While many nuts contain healthful qualities, the walnut may be the most healthy. Walnuts contain high levels of omega-3 fatty acids that help your brain and skin age well. Walnuts also have high levels of antioxidants. In addition walnuts contain l-arginine. This amino acid helps the body produce nitric oxide, which is essential for healthy veins and arteries. Walnuts may also help to erase some of the damage of a high fat meal if you eat a handful as dessert.
