Eating nuts can be beneficial for the health of one's heart, Mayo Clinic advises. Nuts often lower a person's level of low-density lipoprotein cholesterol, which is a major factor in heart disease.
Nuts also reduce blood clotting, which helps prevent heart attacks, Mayo Clinic notes. In addition, nuts are beneficial for the lining of the arteries.
Nuts have the added benefit of being high in omega-3 fatty acids, Mayo Clinic writes. These acids are known for helping prevent dangerous heart rhythms that are sometimes precursors of heart attacks. In addition, nuts are high in fiber, which helps prevent diabetes. Finally, nuts contain vitamin E, which prevents plaque accumulation in arteries.
