The Vitamin C Contents of Various Apple Varities
Vitamin 'C', or ascorbic acid, is essential for human health. The Nutrition Board, National Research Council, recommends a daily intake of 75 milligrams (mg) by the average adult. Children's doses range from 30 mg for the infant to 100 mg for the active boy between 16 and 20. An oversupply of vitamin 'C' to the body is considered harmless, even in multiples of the recommended values.
When an apple tree is growing normally the vitamin content of its fruit will primarily depend on the variety and on the weather. Specifically it depends on the sunlight striking the fruits during the period immediately before picking time. Shaded fruits will contain less vitamin 'C' than more exposed fruits. Within the apple, vitamin 'C' is concentrated in the flesh right under the skin, and decreases towards the core. These variables may explain why research findings are occasionally confusing and incongruent.
The listing below is based on a number of sources and gives average and interrelated values. It is evident that many apple varieties are "good", some even "excellent" sources of this health preserving vitamin.
