We have observed benefits for total nuts, peanuts, tree nuts, and walnuts. They were all associated with lower risk of cardiovascular disease and coronary heart disease. And the intake of peanuts and walnuts was additionally associated with lower risk of stroke.
Almonds, macadamia nuts, hazelnuts and pecans also appear to be quite heart healthy. So are peanuts — though they are technically not a nut, but a legume, like beans. It's best to choose unsalted or unsweetened nuts. Adding salt or sugar to nuts may cancel out their heart-healthy benefits.
Walnuts Help Keep Arteries Clear
Alpha-linoleic acid acts as an anti-inflammatory agent and has actually been shown to help reduce plaque buildup in coronary arteries. Eating walnuts has been shown to improve cholesterol levels and the function of the small arteries and vessels within our bodies.
Eat more vegetables and fruits
Vegetables and fruits are good sources of vitamins and minerals. Vegetables and fruits are also low in calories and rich in dietary fiber. Vegetables and fruits, like other plants or plant-based foods, contain substances that may help prevent cardiovascular disease.
Almonds have been shown to reduce LDL-C, which is a known risk factor for coronary heart disease in several well conducted clinical trials. Studies have also looked at the effect of almonds on HDL-C and it has been found that consumption of almonds have helped maintain or even increase HDL-C levels.
Eating a lot of it, though, promotes artery-clogging atherosclerosis, the process that underlies most cardiovascular disease. In contrast, unsaturated fats, which make up the majority of the fat content in peanut butter, help reduce LDL cholesterol and lower the risk of heart disease.
A healthy diet rich in nutrient-dense foods may help reduce your risk of developing clogged arteries. Research has shown that adding foods like cruciferous vegetables, fish, berries, olive oil, oats, onions, greens, and beans to your diet may be an effective way to prevent atherosclerosis.
Present at higher levels in the pistachio than other nuts, lutein helps prevent cholesterol from clogging up arteries. Experts say it is best to eat unsalted rather than salted pistachios as too much salt can raise blood pressure. However, both types should have the same effect on cholesterol.
Apple & Banana are best fruits for heart blockage that helps in reducing the risk of heart disease and stroke. It contains antioxidants that can help prevent blood clots from forming and causing a heart attack or stroke. Bananas are also a great fruit to eat if you have heart blockage.
Walnuts are a rich source of omega-3 fatty acids (alpha-linolenic acid), which have been shown to have a beneficial effect on cardiovascular health. “Prior studies have shown that nuts in general, and walnuts in particular, are associated with lower rates of heart disease and stroke.
Drinking teas, such as green or black tea, rooibos tea, or ginger tea may be good heart-healthy substitutes for other beverages. A study from 2011 found that drinking 6 cups of rooibos tea per day for 6 weeks helped to lower the amount of LDL cholesterol in the blood in adults who were at risk for heart diseases.
The key is lowering LDL and making lifestyle changes.
"Making plaque disappear is not possible, but we can shrink and stabilize it," says cardiologist Dr. Christopher Cannon, a Harvard Medical School professor. Plaque forms when cholesterol (above, in yellow) lodges in the wall of the artery.
In coronary artery disease, where there is cholesterol plaque buildup in the heart's arteries, healthy lifestyle changes, and medications (such as statins) can stabilize the condition, prevent additional plaque deposits and, in some cases, help reverse the severity of the disease.
Almonds and other tree nuts can improve blood cholesterol. A recent study concluded that a diet supplemented with walnuts can lower the risk of heart complications in people with history of a heart attack.
Can eating too many nuts raise cholesterol? Yes, it is possible that eating nuts in excess may increase LDL cholesterol levels due to their saturated fat content. Eating nuts in excess may also exceed a person's daily calorie needs, leading to increased LDL cholesterol levels.
In addition to its use as a natural sweetener, honey is used as an anti-inflammatory, antioxidant and antibacterial agent. People commonly use honey orally to treat coughs and topically to treat burns and promote wound healing.
Worst nuts for your diet
Ounce for ounce, macadamia nuts (10 to 12 nuts; 2 grams protein, 21 grams fat) and pecans (18 to 20 halves; 3 grams protein, 20 grams fat) have the most calories - 200 each - along with the lowest amounts of protein and the highest amounts of fats.
Nuts like almonds, pistachios, walnuts, peanuts, and hazelnuts are a great source of nutrients, such as protein, fat, fiber, vitamins, and minerals. When eaten as part of a nutrient-dense diet, nuts may reduce your risk of heart disease and support immune health, among other benefits.
