Many fruits and vegetables have a product code label (called a PLU) stuck to them, which can give you information about what to buy and what to avoid. Unfortunately, most of the foods you purchase do not carry such labels, but when they do, here is how you can interpret them.
Most labels will have four digit codes. This denotes that they are conventionally grown (grown with chemical fertilizers and sprayed with pesticides); these foods should be avoided or at least minimized in your diet. A five digit code denotes that the product is not conventionally grown. A five digit code starting with a 9 has been organically grown; include as much of these in your diet as possible. A five digit code beginning with an 8 has been genetically modified; foods carrying this PLU should be completely avoided.
Genetically modified contamination is one reason why no one should purchase food in a supermarket. More than 70 percent of the processed foods in a supermarket now contain genetically modified ingredients and they are not labeled. Do not shop for food in supermarkets, and if you do, purchase only fresh foods with four digit codes or five digit organic codes; avoid processed and prepared foods.
