My child does not eat fruits and vegetables. Will he get vitamin C deficiency?
Vitamin C deficiency may result from a diet deficient in fresh fruits and vegetables. Deficiency of vitamin C causes "scurvy" in humans.
Scurvy is characterized by bleeding gums (gums become swollen, purple, and spongy and the teeth eventually loosen), bleeding under the skin and even bleeding around the bones. This is because synthesized collagen is too unstable to perform its function and thus bleeding in tissues can occur. The hair becomes dry and brittle, and the skin becomes dry, rough, and scaly. Anemia may develop. Infections may develop, and wounds do not heal. The symptoms of scurvy develop after a few months of deficiency.
What is the
treatment of scurvy?
Treatment of scurvy consists of vitamin C supplementation in dose of 100-300mg/day for 10 days. Improvement in diet and intake of citrus fruits is recommended to maintain normal intake of vitamin C.
What happens if

Vitamin C toxicity is very rare, because the body cannot store the vitamin. However, high doses are not recommended because such high doses can lead to stomach upset and diarrhea.
