What’s in nuts that’s thought to be heart healthy?
Although it varies by nut, most nuts contain at least some of these heart-healthy substances:
- Unsaturated fats. It’s not entirely clear why, but it’s thought that the “good” fats in nuts — both monounsaturated and polyunsaturated fats — 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, among other things, preventing dangerous heart rhythms that can lead to heart attacks. Omega-3 fatty acids are also found in many kinds of fish, but nuts are one of the best plant-based sources of omega-3 fatty acids.
- Fiber. All nuts contain fiber, which helps lower your cholesterol. Fiber also makes you feel full, so you eat less. Fiber is also thought to play a role in preventing diabetes.
- Vitamin E. Vitamin E may help stop the development of plaques in your arteries, which can narrow them. Plaque development in your arteries can lead to chest pain, coronary artery disease or a heart attack.
- Plant sterols. Some nuts contain plant sterols, a substance that can help lower your cholesterol. Plant sterols are often added to products like margarine and orange juice for additional health benefits, but sterols occur naturally in nuts.
- 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.
