Vitamin C is water-soluble, and hence, excess ascorbic acid is excreted in urine, as opposed to being stored in the fat tissue
Fresh fruits, such as lemons, kiwi, and oranges, are rich in vitamin C. Vitamin C is sensitive to heat. Consequently, cooking foods destroys much of their vitamin C content
