Where Product Change ?

Food products are different types. They differ not only by the fact that they are limone or tomato or apple spinach. They change and within their type. This change comes given the way they are produced.
So differentiate products, which are:
BIO (natural)
GMO (genetically modified organisms)
BIO products are all those products derived from organic products. They are not genetically modified and are not used pesticides for growth. There are products that grow in a natural manner, but not modified as conditions example field tomato production is natural, whereas greenhouse tomato is cultivated.
Chickens reared in poultry, chickens reared vary by family.
GMO products, are products that are produced genetically interfered by of man. The use of chemicals, pesticides are large quantities. The use of needles (hormones) that promote:
1) Increase the amount of production;
