What are negatives about gm foods?

Answer 1

Since genetically modified foods have been available to consumption for a short period of time, only short-term studies have been conducted. And so far there has not been any side-effects to GM foods reported.

Regarding long term effect, there is not enough data available to even speculate or theorize on it's affect.

Answer 2

Genetically modified (GM) foods are foods derived from genetically modified organisms, either plant or animal. In the context of GM, "genetically modified" refers to organisms that have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise than mutagenesis (mutation breeding) where an organism is exposed to radiation or chemicals to create a non-specific but stable change. Other techniques by which humans modify food organisms which are technically ALSO type of "genetic modification" include selective breeding (both for plants and animals) and somaclonal variation.

No GM animal products are currently on the market although there is ongoing work on modifying animal genetics (selective breeding, the earliest method of genetic modification, has been going on since prehistoric times). In 2006 a pig was produced that had been genetically modified to produce omega-3 fatty acids by inclusion of some roundworm genes that were spliced into the pig genes. Other animals have been modified to have more efficient conversion of their feed into meet or to produce manure with less phosphorous.

Common food staples that have been improved by GM include soybeans, corn, canola (rapeseed), cotton seed oil, alfalfa, tomatoes, sugar cane, sugar beets, rice, squash, and sweet peppers. Improvements include higher nutritional values, disease resistance, herbicide resistance, pest resistance, and resistance to softening and rotting after harvest.

Foods derived from these staples may contain some of the genetically modified versions of the staple. Foods containing GM plant content are more common in the US than in the rest of the world. In Europe and Australia, this is primarily due to political opposition based on competition with non-GM foods produced in European countries and fears of possible unknown side effects of the genetic modification of the plants. In the rest of the world it is more a factor of the unavailability of these foods due to the initial costs of licensing the patented varieties and the comparative poverty of the "3rd world" nations.

Answer 3

The short answer is that the effects of GMO foods on human genes is not known. While some claim there are none, others claim that there are effects on human health brought about by eating GMO foods, though that may or may not be in actual changes in human genes.

Answer 4

The major disadvantage is that farmers in LDCs will have no other choice but to buy GM crops, which are oftn sterile. This means that they cannot keep the seeds and will have to keep on buying the produce, which is expensive.

Answer 5

well,some of the negatives of gm foods are that there are serious health concerns which have led to some animals being sick etc. it has also been known that the spread of the GM foods will be uncontrolable

Answer 6

Genitcailly modified foods will kill us and be the cause of a zombie apocalypse

Answer 7

Effects on human health from eating GMO foods is not known.
