There are lots of reasons to buy organic. First, it's better for the environment. No pesticides means healthier soil, water, and wildlife. Buying organic supports small farmers. Organic farmers can earn a fairer price for organic produce compared to factory farming. Organic farming is good for biodiversity. Organic farmers are growing a wide variety of non-genetically modified (non-GMO) fruits and vegetables. Where factory farming has shrinked our choices in the supermarket to one or two types of any produce variety, organic farmers are resurrecting many heirloom varieties.

Finally, organic foods are healthier for you. The research on whether consuming organic food is healthier for people remains inconclusive. However, the USDA's own tests show that most non-organic produce contain residual pesticides even after washing. The long term effects of consuming these pesticides has not been sufficiently studied, but they can't be good for you.

In a perfect world, we would buy all of our groceries organic. Unfortunately, organic food is still more expensive (although the price is continually dropping) or even unavailable. To make wiser consumer choices here is a list of produce with the highest level of pesticide contamination. The following list is based on information and studies by the United States Department of Agriculture (USDA), Consumer Reports, and the Environmental Working Group.

Here is a list of fruits and vegetables found to contain the least amount of pesticides. Notice that many of these have thick, inedible skins which protect the fruit.

The closer a food is to its natural state, the better it is for you. Fresh fruits and berries are great and will satisfy a craving for sweets. Whole vegetables have lots of vitamins and minerals, so eat more green, orange and yellow vegetables. Steam them to retain the most nutritional value and be careful with sauces, they may be high in calories and fats that aren't good for you. Any pasta or baked goods should be made from whole grains. Avoid sugary snacks and pastries as well. An apple is good for you, an apple pie really isn't.

Shop for lean meats and don't forget the fish. The omega-3 polyunsaturated fatty acids in ocean fish are often deficient in our diets, so serve seafood two or three times per week. Remember to eat a variety of foods to get all of the vitamins and minerals you need to be healthy.

Stick to water, milk and 100% fruit and vegetable juices as your main beverages and limit sugary soft drinks. If you get tired of plain water, add a slice of lemon or lime to add a touch of flavor. For kids, try some fruit juice jazzed up with carbonated water.
