Benefits of Nuts
Nuts contain unsaturated fatty acids and other nutrients. Eating nuts as part of a healthy diet can be good for your heart as most nuts contain at least some of these heart-healthy substances:
- Unsaturated fats: Both monounsaturated and polyunsaturated fats in nuts lower bad cholesterol levels.
- Omega-3 fatty acids: Many nuts are also rich in omega-3 fatty acids. Omega-3s are a healthy form of fatty acids that seem to help your heart by preventing dangerous heart rhythms that can lead to heart attacks.
- Fibre: All nuts contain fibre, which helps lower cholesterol. Fibre also makes you feel full, so you eat less. Fibre could possibly also play a role in preventing diabetes.
- Vitamin E: Vitamin E may help stop the development of plaques in the arteries, which can narrow them. Plaque development in the arteries can lead to chest pain, coronary artery disease or a heart attack.
- Plant sterols: Some nuts naturally contain plant sterols, a substance that can help lower your cholesterol.
- L-arginine: Nuts are also a source of l-arginine, which is a substance that may help improve the health of your artery walls by making them more flexible and less prone to blood clots that can block blood flow.
