Study Notes
Alternative Health Trends
- Growing skepticism towards traditional medical and pharmaceutical industries has led individuals to rely on nutritional supplements.
- The supplement industry has seen significant growth, with worldwide sales reaching $187 billion in 2008.
- Approximately 68% of American adults use dietary supplements, with 52% identifying as regular users.
Apples and Vitamin C Research
- Professor Liu's team investigated the antioxidant effects of vitamin C in apples.
- A 100-gram serving of fresh apples (around half a cup) demonstrated an antioxidant activity equivalent to 1,500 mg of vitamin C.
- Chemically analyzed, the same 100 grams contained only 5.7 mg of actual vitamin C, indicating a significant discrepancy.
- The vitamin C-like activity in apples was found to be 263 times more potent than isolated vitamin C in the same weight.
- This suggests that more than 99% of the antioxidant activity is attributed to other active compounds in apples rather than isolated vitamin C.
Implications on Nutritional Understanding
- The complexity of apples contains hundreds to thousands of different chemicals, each potentially influencing various biological processes.
- Measurement of vitamin C in apples does not accurately reflect their overall health benefits; the presence of isolated nutrients can be misleading.
- Antioxidant power cannot be determined solely by the amount of vitamin C present in the fruit.
