Determine some Dietary Sources of Vitamin C?

Fruits (particularly citrus fruits), vegetables are the best sources of ascorbic acid. Amla is the richest source of ascorbic acid. The amount of ascorbic acid in plants varies greatly, depending on such factors as the variety, weather and maturity. Organ meats (e.g., liver and kidney) generally are also good sources of vitamin C. However, muscle meats and most seeds do not contain significant amounts of ascorbic acid.

Remember, the most significant determinant of vitamin C content in foods is how the food is stored and prepared.
