May lower cholesterol

Observational studies have linked elevated cholesterol levels to an increased risk of heart disease. According to one study, persons who ate an average of 25 grams of soy protein per day experienced a 3-4 percent drop in low-density lipoprotein cholesterol. It is unknown if these little improvements in cholesterol levels translate into a decreased risk of heart disease. Despite these concerns, the Food and Drug Administration (FDA) permits soy protein health claims for heart disease prevention.

Edamame is high in fiber, antioxidants, and vitamin K, in addition to being a good source of soy protein. These plant chemicals may lower the risk of heart disease and enhance the blood lipid profile, which is a measurement of lipids that includes cholesterol and triglycerides.
