I think I'm understanding this question? That, are genetically engineered foods healthy? That's how I shall answer the question.
In some ways most human food has been altered. Often by genetics, through deliberate selection, for whatever traits we wish from the plant. The deliberate introduction of genetic material for other reasons. e.g. DNA from fish; or for resistance from pesticides. I see as insidious.
One of the prime motivators for products resistant to pesticides, is Monsanto. From their labs we are given "roundup ready" products like canola; or what was once known as "rapeseed", for oil. Round-up in an earlier life was known as "Agent Orange". Used in that part of Asia that held the Viet-Nam conflict in 60's and 70's.
The draconian measures adopted by this company, under the pretext of "copyright protection". Has driven a number of small farms under financially; especially in places like India. These small farms are then gobbled up by large agro-businesses. Even if the organic farmer next door, who is not using their products. Then pollination by natural means, has seen Monsanto successfully sue these farmers. For robbing them of their patents? BTW. Studies have already shown that the insects and plants not wanted in among the intended crop. Change their DNA structure within a few generations, so they are able to return to those pastures. Where they are deemed "undesirable".
Now with an enlarging population, it is claimed that humanity needs these products for better efficiency of crop yield to cope, with keeping us all fed?
Health? Well there is information out there. Yet little is known on the long or short-term effects on health, since most of the studies done were paid for by Monsanto, etc.
Personally, I try to avoid any foods suspected of being GMO. However, the labelling laws make it almost impossible for the consumer to know what is, or is not, GMO foods.
For me, genetic splicing. Seems like an un-natural and by extension un-healthy. Way of providing the necessity of life; food. I suspect that most people feel that way too?
