You're in a bit of a dilemma standing in front of the produce section of your local supermarket. In one hand, you're holding a conventionally grown Granny Smith apple.In your other hand, you have one that's been organically grown. Both apples are firm,shiny and green. Both provide vitamins and fiber, and both are free of fat, sodium and cholesterol.
The conventionally grown apple costs less and is a proven family favorite. But the organic apple has a label that says "USDA Organic". Does that mean it's better? Safer? More nutritious? Several differences between organic and non-organic foods exist. Become a better informed consumer for your next trip to the supermarket.
The word "organic" refers to the way farmers grow and process agricultural products, such as fruits, vegetables, grains, dairy products and meat. Organic farming practices are designed to encourage soil and water conservation and reduce pollution.Farmers who grow organic produce and meat don't use conventional methods to fertilize, control weeds or prevent livestock disease.

These standards regulate how such foods are grown, handled and processed.Any farmer or food manufacturer who labels and sells a product as organic must be USDA certified as meeting these standards. Only producers who sell less than $5,000 a year in organic foods are exempt (免除) from this certification.
