These days witness scientific approach to many aspects of our environment, and this situation makes people less careful about their choices. We got used to purchasing various objects (no matter if they are eatable or non-eatable) that are not fully natural and often converted by manufactures into something incomprehensible, but entirely accepted for consumption by modern society. This is exactly what food producers do with genetically modified products, and though some of their excuses might be justified, you will be better off if you totally avoid this kind of food.
If you follow this advice, your genes will not be prone to genetic transformation caused by intake of modified mess. Try to be wiser in your food choices, and you will soon feel the benefits of your new approach.
