The Top 5 Healthiest Foods on the Planet

1) Lemons:
— Just one lemon has more than 100 percent of your daily intake of vitamin C, which may help increase "good" HDL cholesterol levels and strengthen bones.
— Citrus flavonoids found in lemons may help inhibit the growth of cancer cells and act as an anti-inflammatory.

2) Broccoli:
— One medium stalk of broccoli contains more than 100 percent of your daily vitamin K requirement and almost 200 percent of your recommended daily dose of vitamin C — two essential bone-building nutrients.
— The same serving also helps stave off numerous cancers.

3) Dark Chocolate:
— Just one-fourth of an ounce daily can reduce blood pressure in otherwise healthy individuals.
— Cocoa powder is rich in flavonoids, antioxidants were shown to reduce "bad" LDL cholesterol and increase "good" HDL levels.


4) Sweet Potatoes:
— One red potato contains 66 micrograms of cell-building folate — about the same amount found in one cup of spinach or broccoli.
— One sweet potato has almost eight times the amount of cancer-fighting and immune-boosting vitamin A you need daily.

5) Salmon:
— A great source of omega-3 fatty acids, which have been linked to a reduced risk of depression, heart disease, and cancer.
— A 3-ounce serving contains almost 50 percent of your daily dose of niacin, which may protect against Alzheimer's disease and memory loss.
