Farmer's markets are a great place to find lots of fresh real food.The food is usually grown locally so it has not been transported over long distances before you buy it. Many farmer's markets offer organically grown produce. You can often speak to the person who planted and harvested the crop to ask questions about the use of pesticides and GMO (genetically modified organism) seeds. Organic farmers are great advocates for eating real food and are frequently willing to discuss their growing methods with you.
