"Is Organic More Nutritious?"
|
Surveys show that most people who buy organic produce think it is more nutritious. Is it? That question is impossible to answer on the basis of recent research. Many factors affect nutrition levels in fresh produce—soil type, climate, season, plant varieties, shipping, and handling. Such variables make it hard to devise studies comparing nutrients in organic and conventionally grown produce. One study in 2003 found that vitamin C was higher in organic potatoes and leafy greens, but other nutrients were the same. In another study, researchers found higher levels of vitamin C and various phytochemicals in one type of organic tomato, but no difference between organic or conventional bell peppers. Overall the findings have been inconclusive or inconsistent.
