Yes, they do. The trouble is, no one knows how much, how fast, or how bad the effects are exactly, and the people pushing for more use of such foods are aggressively opposed to doing any research that might show any negative results because they would lose money.

Any food can be genetically modified through genetic engineering. Three foods that have been genetically engineered are corn, soy, and canola.
We have genetically modified foods for centuries by selective cross breeding plants. With out this and other modern methods of farming perhaps a billion people now existing on a substance diet would starve to death.
Genetically modified foods will go bad. The only thing that is different is the size and nutritional value of it.
In general, non-genetically modified foods of any type (including whole soybeans) are preferred to the their genetically modified counterparts because the long-term health effects of consuming genetically modified foods have not been properly documented yet. There may be unanticipated health risks with consuming certain genetically modified foods.
Genetically modified
Genetically enhanced. Pretty much the same as genetically modified.
Any food that comes from a plant, animal, or other living thing can be genetically modified.
One of the disadvantages of the genetically modified foods is that it allows animal products in plants which could raise issues for those with dietary restrictions like the vegans. The advantage of the genetically modified foods is that they can increase the crop yield in a very small acreage.
Organically grown foods are not (trans)genetically modified, meaning they are not what is considered GMOs.
The first genetically modified food began in 1994. Scientist genetically modified a tomato which didn't ripen so quickly after it was picked.
Sadly, almost all the food out there is genetically modified(gm). You can find more natural foods by purchasing organic or all natural products, but they are not guaranteed to be gm free.
