The cross breeding of Plants and Animals dates back as far as Kemet in fact there are early references to it in the Bible ie: Genesis 30:35-43 

The baby boom generation remembers that tomatoes were not meaty like they are now but they had big holes inside them and had a million seeds. They also grew on long running vines and not stalks. They were scientifically bred to stalks so that tractors could cultivate around the plants for faster and greater yields. Beans were all vines (poll beans) bred out into stalks (bush beans) around 1954 started the change over. Of course when this is done some of the nutrient value is lost but still edible. Cross breeding is mostly done for commercial appeal (to look more appetizing at the market place. Most of the foods on our tables now are actually hybrid. Even so this method relies on certain tenancies within nature to influence the spices alteration.

On the other hand GMO (Genetically Modified Organism) Is done by manipulating the atomic and molecular structure of the RNA and DNA of the Plant or Animal to be altered Strictly for commercial purposes. These methods include use of Atomic Radiation, Chemical modification or introduction of a self perpetuating virus that causes all the cells to develop differently than their natural structure. Therefore the nutrient inclusions that we expect from whatever spices it is will be way different than what is was originally. Our bodies don't recognize it. Most of the time after eating it you are still hungry. Ultimately it will genetically modify your body (You are what you eat) And it will be hard to stay well.
