What would you like to do?
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.

Yes. Research with genetically modified foods approved by the FDA have been found to be safe and otherwise normally tolerated. Perhaps the biggest concern in creating ne…w genetically modified foods is the potential for allergies- a plant containing a peanut gene might cause a reaction in those allergic to peanuts.
They can be herbicide resistant have a longer shelf life but some ethical concerns are nobody really knows the long-term effects and is it right to interfere with nature in th…is way? Sources: EDEXCEL GCSE Science - revision and classroom companion.
This is an area that has not been studied enough to provide an easy-to-understand answer or even something that could be encapuslated into a few sentences. No peer-revie…wed publications of clinical studies on the human health effects of genetically modified food exist. Even animal studies are few and far between. Most studies undertaken to assess whether Genetically Modified foods have been sponsored by companies DOING the modifications with the goal of making a specific crop insect or disease resistant, or increasing the output. Thus stated, they have a vested interest in seeing the study produce positive results that affirm the safety of the product. Such studies cannot be relied upon as accurate. Scientists have identified some of the significant risks of introducing modifications to the genetic structure of crops and livestock, and they include: * GM foods may cause allergies. Introduction of genetic elements into the existing system which has been refined by millions of years of natural selection, can have unpredictable results. Toxins and allergens may be produced. * DNA does not always breakdown completely in the digestive tract, and bacterial flora present there may actually take up components of those genes and incorporate them into their own structure. This can lead to antibiotic resistance. Few genetically modified foods are brought to market with the intent of improvement of the health of the person consuming them. The reasons most often have to do with the economics of producing the product, or making the product hardier to prevent monetary loss from insect damage or spoilage. Other reasons may include changing the flavor or texture of a food, to make it more palatable to a larger segment of the population, which would naturally increase sales.
Genetically modified food, sometimes called Round-Up Ready, has been genetically modified to accept certain pesticides better (Monsanto's Round Up, for example). It is not of… greater nutritional value, it does not grow better, it does not grow faster, and it does not resist bugs better. It merely accepts pesticides better meaning you can use less. If your neighbor grows GMF and it spreads to your fields (by wind or bug or whatever), you will be charged a fee for having it in your field. Also whether or not the food is safe in humans has not been determined by any long-term studies. Who does it effect? Potentially everyone because once that genie is out of the bottle, there is no telling what long-term effects it will have on us or the environment.
Long term effects of GMO food on humans is not known. There is some anecdotal evidence that it may have adverse health effects on humans. That evidence includes patients of do…ctors having improved health when they stop eating GMO foods.
Though many say GMO foods have been proven to be safe for human consumption, there are some issues that may be connected to humans eating GMO foods that make the safety of… GMO foods questionable.
There are no known bad effects to growing genetically modified foods to date according to scientific studies, though there are those who believe anecdotal evidence suggests th…ere are some harmful effects to health.
There have been countries that have refused to import grains that contain GMOs, so it has resulted in negative effects on the GDP.
there are no known harmful effects of GMO's
Production costs are reduced with GM-crops due factors such as preservation of crops from insects and other pests, shorter growth periods, larger yields per acre and decreased… use of natural resources.
none, not human
There are no scientifically proven effects of any kind. However, as with any new technology, there is much rumor and conjecture, from simple allergies to the notion that it co…uld somehow change the human genome.
Some argue that genetically modified food has no effects on human or animal genes. They also argue that GMO foods are the same as any other foods and have no negative heal…th effects at all. Others argue that they might cause changes to our genes, and that they do cause changes to the flora in our intestines, possible sterilization, and other health issues. The FDA has declared then to be "substantially equivalent" to non GMO foods. In reality, we just do not know what effects genetically modified food have on our health or our genes.
The FDA classified genetically modified foods as "substantially equivalent" to non-GMO foods. They do not have to pass human testing prior to being produced and sold to co…nsumers or at any other time.
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.
Long lasting, or long term, effects of GMO food are not known. There were no long-term human studies done before genetically engineered foods were commercially sold. There is …some evidence, such as patients of doctors switching to non GMO diets and their health improving, that suggests GMO foods may have negative health effects.
The harmful effects of the genetically modified food to health is that they contain cancerous cells.
