Fruits High In Ascorbic Acid

Ascorbic acid, more commonly referred to as vitamin C, is water-soluble vitamin required for repairing and growing tissues, particularly collagen -- the protein responsible for producing skin, ligaments, tendons, cartilage and blood vessels, according to the University of Maryland Medical Center. Ascorbic acid is also a powerful antioxidant that requires daily replenishing, as your body does not store it. Consuming fruits high in ascorbic acid can deliver adequate amounts each day.

Kakadu Plum

Kakadu plum is well-known for its high amounts of ascorbic acid and is native to northwestern Australia, according to Susanna Lyle in the book "Fruits and Nuts." Said to be similar to the gooseberry, the Kakadu plum has the highest known amount of vitamin C per volume of any fruit in the world, Lyle says. Just 100 g of Kakadu plum contains between 3,2000 mg to 5,000 mg of vitamin C. Usually eaten raw, Kakadu plums are light green in appearance and usually made into jam.

Acerola

Acerola is an exceptionally rich source of vitamin C with origins in Yutacan culture, according to the California Rare Fruit Growers website. This fruit is distributed from South Texas and through Central and South America, as well as the Caribbean. It has a distinct cherry-like appearance with delicate bright red skin, although they may also come in yellow-orange. Every 100 g of acerola contains between 1,400 to 4,000 mg of vitamin C, the site notes.

Citrus Fruits

Citrus fruits are the more commonly thought of fruits when looking to increase vitamin C intake, as they are relatively high in vitamin C when compared to other fruits. The citrus family includes oranges, grapefruits, lemons, limes and others, according to Milind Ladaniya in the book "Citrus Fruit." Citrus fruits contain between 34 to 55 mg of ascorbic acid per 100 g of a fruit. Oranges contain the most vitamin C out of this fruit family. The author warns that diabetics should watch their intake of citrus fruits as they can cause a spike in blood sugar and should consider other means of procuring vitamin C, such as supplements.
