What of diffrerence in nutrinional between organic food and non-organic food?

For the myths, there is no nutritional difference between organic food and non-organic food.

For the reality : Chemical farming damages the natural fertility of soil because it kills or suppresses the beneficial soil organisms that help ensure the nutrient richness of soil. The soil on an organic farm is loaded with these beneficial organisms and is chock-full of micro-nutrients. The result is that organically grown plants are healthier and more resistant to disease, and the food from them is more nutrient-rich. Research done at the University of California at Davis found that organically grown berries, corn and vegetables have over 50% more antioxidants than the same conventional crops. (Antioxidants are nutrients important to avoiding cancer and maintaining good overall health.) Studies also suggest that organic foods are higher in a variety of minerals.

Organic farming also does not cause the many problems associated with modern conventional farming, such as groundwater and streams that become polluted with pesticides or rivers and bays that are dying from oxygen deprivation due to fertilizer runoff.

So, that should dispel some of the common misperceptions about organic agriculture and organic food. The really good news is the taste of organic food—most people think it has much more flavor than conventionally produced food. And just think about it: Do you really want your kids sticking non-organic french fries up their noses?
