What is organic food, anyway?

Though organic food can be produced with certain synthetic ingredients, it must adhere to specific standards regulated by the United States Department of Agriculture (USDA). Crops are generally grown without synthetic pesticides, artificial fertilizers, irradiation (a form of radiation used to kill bacteria), or biotechnology. Animals on organic farms eat organically grown feed, aren't confined 100 percent of the time (as they sometimes are on conventional farms), and are raised without antibiotics  or synthetic growth hormones.

Is organic food better for me?

Organic foods may have higher nutritional value than conventional food, according to some research. The reason: In the absence of pesticides and fertilizers, plants boost their production of the phytochemicals (vitamins and antioxidants) that strengthen their resistance to bugs and weeds. Some studies have linked pesticides in our food to everything from headaches to cancer to birth defects — but many experts maintain that the levels in conventional food are safe for most healthy adults. Even low-level pesticide exposure, however, can be significantly more toxic for fetuses and children (due to their less-developed immune systems) and for  pregnant women  (it puts added strain on their already taxed organs), according to a report by the National Academy of Sciences.

Pesticide contamination isn't as much of a concern in meats and dairy products (animals may consume some pesticides, depending on their diet), but many scientists are concerned about the antibiotics being given to most farm animals.
