As of June 2015, some popular superfoods that promote good health are tomatoes, blueberries, kale and black beans, states Health Magazine. Other superfood options include broccoli, salmon and oats.
Tomatoes are superfoods due to their large amounts of potassium, fiber and vitamin C, Health Magazine explains They also contain lycopene, an antioxidant that can lower cholesterol and possibly prevent cancer.
Blueberries contain many phytonutrients, which neutralize free radicals. They may help fight Alzheimer's disease and dementia as well as prevent cancer, reports Health Magazine. Blueberries can also improve short-term memory, balance, coordination and eyesight, explains Healthline.
Kale is a popular superfood because of its high nutrient content. It contains 45 different flavanoids as well as lutein and beta-carotene, Healthline states. The high fiber content in kale helps reduce cholesterol, while omega-3 fatty acids may also reduce inflammation. Due to the anti-inflammatory properties and glucosinolates it contains, kale may be useful in fighting cancer.
Similar to kale, broccoli is a cruciferous vegetable that may reduce the risk of cancer, reports the National Cancer Institute. More specifically, the isothiocyanate sulforaphane found in broccoli is believed to fight cancer, Healthline states.
Black beans and lentils are two more widely praised superfoods because of their high protein content and lack of saturated fat. They are also good sources of fiber, antioxidants and iron, states Health Magazine.
