Legumes
Because they come from plants, legumes such as beans, lentils, and peas are an excellent source of protein without a lot of unhealthy fat. One study found that people who ate legumes at least four times a week had a 22% lower risk of heart disease compared with those who consumed them less than once a week. And legumes may help control blood sugar in people with diabetes. Lowering blood sugar levels is key in helping people avoid diabetes complications, one of which is heart disease.
olive oil
In a landmark study, people at high risk for heart disease who followed the Mediterranean diet (high in grains, fruits, vegetables) supplemented by nuts and at least four tablespoons a day of olive oil reduced their risk of heart attacks, strokes, and dying by 30%. Olive oil is a good source of monounsaturated fats, which can help reduce both cholesterol and blood sugar levels. Olives themselves—both green and black—are another source of “good” fat
Red wine
Red wine, or small amounts of any type of alcohol, are thought to lower heart disease risk. (Higher amounts, more than a drink or two a day, can actually increase risk.) While some say a polyphenol found in red wine, resveratrol, gives that beverage an added benefit, research suggests that any type of alcohol in moderation works. As with coffee, though, none of these properties are a reason to start drinking alcohol
Broccoli, spinach and kale
When it comes to your health, you really can’t go wrong with vegetables. But green vegetables may give an extra boost to your heart. These are high in carotenoids, which act as antioxidants and free your body of potentially harmful compounds. They’re also high in fiber and contain tons of vitamins and minerals. Kale also has some omega-3 fatty acids. “Green vegetables are super health-promoting foods
Avocado
These soft, tasty fruits have a well-established reputation for providing the body and heart with healthy fats. Like olive oil, they’re rich in the monounsaturated fats that may lower heart disease risk factors, such as cholesterol. They’re also high in antioxidants and in potassium
Pomegranate
Pomegranates contain numerous antioxidants, including heart-promoting polyphenols and anthocyanins which may help stave off hardening of the arteries. One study of heart disease patients found that a daily dose of pomegranate juice over three months showed improvements in blood flow to the heart. Ultimately, though, it’s important to have variety in your diet. If you don’t like pomegranates or can’t afford them, reach for apples, which also contain plenty of health-promoting compounds
Nuts
This includes almonds, walnuts, pistachios, peanuts and macadamia nuts, all of which contain good-for-your-heart fiber. They also contain vitamin E, which helps lower bad cholesterol. And some, like walnuts, are high in omega-3 fatty acids. “Some people in the past have avoided nuts because they’re higher in fat, but most of the studies show that people who consume nuts daily are leaner than people who don’t
Soy
Soy products, including tofu and soy milk, are a good way to add protein to your diet without unhealthy fats and cholesterol. Soy products contain high levels of polyunsaturated fats (good for your health), fiber, vitamins, and minerals. What’s more, soy may reduce blood pressure in people who eat a diet high in refined carbohydrates. And compared with milk or other proteins, soy protein can actually decrease LDL or “bad” cholesterol.
