Nuts and heart disease risk
Including nuts as part of your diet has been linked with a lower risk of heart disease.
Although high in fats, nuts are good sources of healthy fats (such as monounsaturated and polyunsaturated fats), and are low in (unhealthy) saturated fats.
LDL cholesterol can add to the build-up of plaque (fatty deposits) in your arteries, which can increase your risk of coronary heart disease.
Nuts also help to maintain healthy blood vessels and blood pressure (through their arginine content), and reduce inflammation in the body as they are high in antioxidants.
