Several large studies have linked nuts to lower heart disease risk and longer life. In the landmark Nurses' Health Study, for instance,women who ate the most nuts (about 5 oz per week) had half the risk of heart attack as those who rarely ate them. Although the power sources in nuts is unclear, researchers suggest that their unsaturated fats, magnesium, copper, folic acid, protein, potassium, fiber, and vitamin E may all play a part.
The type of nut you eat isn't that important. Walnuts, almonds, hazelnuts, you name it, almost every type of nut has a lot of nutrition packed into a small package. If you have heart disease, eating nuts instead of a less healthy snack can help you more easily follow a heart-healthy diet. Most studies on public who consume nuts as part of a heart-healthy diet have found that nuts lower the LDL, low-density lipoprotein or "bad" cholesterol level in the blood. High LDL is the main causes of heart disease, so nuts' aptitude to lower LDL cholesterol looks to be beneficial.
Consumption of nuts lessens your possibility of developing blood clots that capable of cause a fatal heart attack. Nuts also improve the health of the lining of your arteries. The facts for the heart-health benefits of nuts aren't rock-solid yet the Food and Drug Administration only allows food companies to say proof "suggests but does not prove" that eating nuts lessen heart disease risk. Still, the obtainable evidence looks promising. It's entirely unclear, but it's thought that the unsaturated fats in nuts both monounsaturated and polyunsaturated fats lower bad cholesterol levels. Many nuts are also rich in omega-3 fatty acids.
Omega-3s are a healthy form of fatty acids that appear to help your heart by, among other things, preventing unsafe heart rhythms that can lead to heart attacks. Omega-3 fatty acids are also found in fish, but nuts are one of the premium plant-based sources of omega-3 fatty acids. Nuts also have lots of argentine, which is a molecule that amplify the production of nitric oxide in your body, which may in turn help improve the health of your artery walls and make them more flexible and less prone to blood clots. Other substances in nuts that could improve your heart health include Vitamin E and fiber. Generally nuts become the most visible good food for your health. Walnuts are one of the best-studied nuts, and it's been exposed they contain high amount of omega-3 fatty acids.
Almonds, macadamia nuts, hazelnuts and pecans are other nuts that show to be heart healthy. Even peanuts which are technically not a nut, but a legume seem to be relatively healthy. Keep in mind; you might end up canceling out the heart-healthy benefits of nuts if they're covered with chocolate, sugar or salt. Nuts contain a lot of fat; as much as 80 percent of a nut is fat. Even though the majority of this fat is healthy fat, it's still a lot of calories.
That's why you should eat nuts in moderation. Preferably, you should use nuts as a alternate for saturated fat. Instead of eating unhealthy saturated fats, try substituting a handful of nuts. Present dietary guidelines recommend eating 1 to 2 ounces (a small handful) of nuts each day. But again, do this as part of a heart-healthy diet. Just consumption of nuts and not cutting back on saturated fats establishes in many dairy and meat products won't do your heart any good.
Nuts contain Vitamin E, which, in addition to possibly being good for your heart, is consideration by some researchers to help protect your cells against some forms of cancer. However, the proof for Vitamin E's benefits in heart disease or cancer prevention is rather slim at the moment. One more theory is that Vitamin E might help prevent cataracts.
Nuts also contain fiber, and a high-fiber diet is thought to help prevent heart disease and diabetes. A diet too much in foods that contain fiber also might help prevent colon cancer. Nut oils are outstanding sources of omega-3 fatty acids and vitamin E.
Walnut oil is highest in omega-3s. Nut oils consist of saturated and unsaturated fats. Using nut oils in homemade salad dressing or in cooking is an option. When using nut oils in cooking, keep in mind that they respond in a different way to heat than do vegetable oils. Nut oil, if overheated, can become bitter.
Just like with nuts, use nut oil in moderation to restrict overall calorie and fat intake. On every continent and for thousands of years, nuts have been an important food for humans, and for good reason. Nuts are good for you they are cholesterol-free and contain healthy, unsaturated fats, which can help lower the risk of heart disease. Nuts also provide magnesium, which helps maintain bone structure; and chromium, which helps to ensure proper insulin function.
They contain zinc for growth and wound healing, and manganese, which protects against free radicals.
