Help to Improve Heart Health

Romaine lettuce is high in folate, a B vitamin that converts homocysteine to methionine. Unconverted homocysteine can cause blood vessel damage and plaque formation, endangering the heart. Lettuce also contains a lot of vitamin C, which aids in the treatment of cardiovascular disease by lowering arterial stiffness. It may aid in the prevention of heart attacks by strengthening arteries. Two servings of romaine lettuce each day can help your heart stay healthy.

Lettuce also contains potassium, which aids in the prevention of heart disease by reducing blood pressure. Eating lettuce can also increase HDL (good cholesterol) levels while decreasing LDL levels. Another study found that eating lettuce helps with cholesterol metabolism. It also boosts the body's antioxidant capacity. Regular consumption of lettuce can aid in the prevention of cardiovascular disease.
