Even after you wash certain fruits and vegetables, they still contain much higher levels of pesticide residue than others.
Organic produce is not contaminated with synthetic chemicals used as pesticides. (Pesticides derived from a natural source are allowed to be used in organic foods).
Buying organic provides assurance that your food hasn't been genetically modified or treated with ionizing radiation.
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.
Organic meat, poultry, eggs, and dairy products come from animals that eat organically grown feed, and they are not given antibiotics or growth hormones— which have been linked to increased antibacterial resistance in humans. Organically raised animals also have access to the outdoors.
