Leafy greens, olive oil, lemons, flaxseed, salmon, broccoli and oatmeal are some of the healthiest foods in the world. Different foods have varying health benefits, so it is important to get vitamins, minerals and nutrients from a variety of sources, advises WebMD.
Kale has the highest amount of antioxidants of all of the leafy greens. Other exceptionally healthy greens include mustard greens, Swiss chard, broccoli rabe and spinach. Greens are excellent fiber sources. Olive oil pairs well with leafy greens, and it contains powerful antioxidants. Studies also suggest that olive oil reduces the chances of getting colon and breast cancer, according to WebMD.
Lemons contain a substantial amount of vitamin C, which increases positive HDL cholesterol levels and also strengthens bones, states Fitness magazine. Lemons act as an anti-inflammatory agent. Lemon pairs well with another healthy food, salmon, which contains important omega-3 fatty acids. The omega-3 fatty acids may reduce the risk of heart disease, depression and cancer. Broccoli, an excellent accompaniment to salmon, is an powerful source of vitamin K.
Flaxseeds are healthy because they have a significant amount of fiber, which is important for maintaining healthy cholesterol levels and reducing constipation, WebMD states. Like salmon, flaxseeds contain omega-3 fatty acids. Oatmeal is another healthy food, because it helps to clear the system of cholesterol.
