How to Avoid Genetically Modified Foods

• Become familiar with the most common applications of genetic modification. These are the products (and their derivatives) that are most likely to be genetically modified: (See list)
  
• Buy food labeled 100% organic. The US and Canadian governments do not allow manufacturers to label something 100% organic if that food has been genetically modified or been fed genetically modified feed. However, you may find that organic food is more expensive and different in appearance from conventional products. Also, just because something says "organic" on it does not mean that it does not contain GMs. In fact, it can still contain up to 30% GMs, so be sure the labels say 100% organic.
  
  This applies to eggs, as well. Eggs labeled "free-range", "natural", or "cage-free" are not necessarily GE-free; look for eggs to be 100% organic.
• Recognize fruit and vegetable label numbers. If it is a 4-digit number, the food is conventionally produced. If it is a 5-digit number beginning with an 8, it is GM. However, do not trust that GE foods will have a PLU identifying it as such, because PLU labeling is optional. If it is a 5-digit number beginning with a 9, it is organic.
• Purchase beef that is 100% grass-fed.
• Seek products that are specifically labeled as non-GM or GMO-free.
• Shop locally. 
• Buy whole foods. Favor foods that you can cook and prepare yourself, rather than foods that are processed or prepared (e.g. anything that comes in a box or a bag, including fast food). What you lose in convenience, you may recover in money saved and satisfaction gained, as well as increased peace of mind. Try cooking a meal from scratch once or twice a week--you may enjoy it and decide to do it more often.
