Antioxidants
in Organic Foods |

Eating organic foods: The higher level of antioxidants in the organically grown food is enough to have a significant impact on health and nutrition. More information about organic foods:

The Journal of Agricultural and Food
Chemistry, a peer-reviewed journal of the American Chemical Society
published a study led by Alyson Mitchell, Ph.D., a food scientist at the
University of California, Davis. The investigation compared the total
antioxidants found in foods grown organically (using no herbicides,
pesticides or fertilizers) to foods grown sustainably (in this study
fertilizers but no herbicides or pesticides were used) and conventionally
(using synthetic chemicals to protect the plants and increase yield).
Flavonoid polyphenolics (also known as bioflavonoids) are present in many dark berries such as pomegranate,seabuckthorn, noni, blueberries, and blackberries, as well as in certain types of tea and coffee, especially green tea. Coffee, however, is often depleted of antioxidants due to the high-temperature roasting process. Flavonoids are phenolic compounds that have potent antioxidant
activity. They are produced in plants in response to environmental
stressors, such as insects or competing plants. The need for these natural
safeguards decreases with the use of herbicides and pesticides in
conventional agriculture. This decrease is reflected in the total amount
of antioxidants the plants produce. "This helps explain why the level of antioxidants is so much higher in organically grown food," Mitchell says. "By synthetically protecting the produce from these pests, we decrease their need to produce antioxidants." |
