Blueberries, a popular example of a superfood, are not especially nutritious, having high content of only three essential nutrients: vitamin C, vitamin K and manganese.
Cape gooseberry (inca berry)
Low in calories and contains modest levels of vitamin A, vitamin C, vitamin B1 and vitamin B3, while other nutrients are at low levels. Basic research on the cape gooseberry has provided preliminary evidence that its constituents, possibly polyphenols and/or carotenoids, may have anti-inflammatory and antioxidant properties.
Goji berry (wolfberry)
Goji berries are small red berries, smaller than an average sultana, that are generally dried and then rehydrated to be traditionally consumed in teas, soups, sauces and alcohols of China and Japan. They are known to be exceptionally high in antioxidants, and studies have shown consumption “increases plasma zeaxanthin and antioxidant levels” which suggests a general health benefit with particular respect to reducing vision degradation due to aging.
Kakadu Plum is the latest “super fruit” to emerge on the world market. A traditional “bush food” native to Australia’s Northern Territories, the kakadu plum is said to have nature’s highest concentration of vitamin C as well as unique phytonutrients not found in other fruits.
A small tropical fruit (Myrciaria dubia) shaped like a cherry that contains high vitamin C content, flavonoids and anthocyanins. A 2008 study suggested that it may have powerful anti-oxidative and anti-inflammatory properties.
Citrus (including oranges,grapefruits and lemons)
Citrus fruits are considered to be a superfood for skin care because they contain phytonutrients that function as antioxidants, protecting you from free radicals that damage skin cells and lead to signs of aging. Plus, just one orange provides more than the daily requirement of vitamin C needed to fortify muscles, blood vessels, bones and teeth.
Coconuts may help benign prostatic hyperplasia. The hexane fraction of coconut peel may contain novel anticancer compounds. Young coconut juice has estrogen-like characteristics.
The coconut water has been marketed as a natural energy or sports drink due to its high potassium and mineral content. Low levels of fat, carbohydrates, and calories.
Pouteria lucuma (one of two species sometimes known as “eggfruit”) is a subtropical fruit native to the Andean valleys of Peru. It has high levels of carotene, vitamin B3, and other B vitamins.
