Additionally, the FDA decided that we do not need to know whether we consume natural or modified species with frog genes in order to resist low temperatures. That is why we are going to tell you an easy way in which you can distinguish natural and GMO foods and know what you really consume.
If you are worried that you may be consuming genetically modified fruits or vegetables you can tell them apart by their code. Namely, the genetically modified products (the ones that are injected with chemicals in order to grow) are labeled with a code of 4 digits in their price tag, while the natural ones are labeled with a 5 digit code stating with the number 9.
Some genetically modified products may also have 5 digits but start with 8.
This is actually very important because 80% of the food in the United Stated is genetically modified. That is why it is important to tell them apart and this advice is very useful for that purpose.
In some European countries (Germany, France, Austria, Hungary, Luxemburg and Greece) the production and sale of genetically modifies products is forbidden.
