Top 10 Vitamin C-Rich Fruits

Vitamin C is essential for the growth and development of the body. While it is recommended to consume foods rich in fruits high in vitamin C, many people prefer to take dietary supplements for their ascorbic acid intake.

Ascorbic acid is necessary for the biosynthesis of collagen, L-carnitine, as well as in protein metabolism. Collagen is an essential component of connective tissue, playing a vital role in wound healing. Vitamin C is also an important physiological antioxidant.

Benefits of Vitamin C

Vitamin C is water-soluble and found naturally in fruits and vegetables. It has the following roles:

• It contributes to the formation of an important protein used to make skin, tendons, ligaments, and blood vessels;
• It repairs and maintains cartilage, bones, and teeth;
• It may reduce the risk of chronic diseases;
• It may decrease the risk of uric acid in the blood and help prevent gout attacks;
• It improves immunity;
• It protects memory and thinking ability.

Recommended Dietary Intake from Vitamin C-Rich Fruits

For adults, the recommended daily amount of vitamin C is 65-90 mg/day, with an upper limit of 2,000 mg/day. Smokers require 35 mg/day more Vitamin C than non-smokers.

Vitamin C Deficiency

Acute vitamin C deficiency leads to scurvy. Symptoms vary depending on the body’s vitamin C stores, but signs can appear within a month following reduced vitamin C intake (below 10 mg/day).

Initial symptoms include fatigue, malaise, and gum inflammation.

As the deficiency progresses, collagen synthesis deteriorates and connective tissues become weakened, causing petechiae, ecchymoses, purpura, joint pain, poor wound healing, and hair abnormalities.

Other symptoms may also occur, such as depression, swollen and bleeding gums, loosening or loss of teeth due to tissue and capillary fragility, and anemia due to increased bleeding and decreased non-heme iron absorption.

If left untreated, scurvy is fatal. Today, vitamin C deficiency and scurvy are rare in developed countries. Symptoms of excessive deficiency only occur if vitamin C intake drops below approximately 10 mg/day for several weeks.

Natural Sources of Vitamin C

Fruits and vegetables are the best sources of Vitamin C. The Vitamin C content in food can be reduced by prolonged storage and cooking, as the vitamin is water-soluble and destroyed by heat.

Fortunately, many of the best dietary sources of Vitamin C are usually consumed raw. Eating 5 varied portions of fruits and vegetables a day can provide over 200 mg of Vitamin C.
