* No, any that is, you will know about it before you buy it. The labels on gm foods are clear to make sure there is no confusion. Also, it would be illegal for them not to state whether a food is gm or not because as a consumer, we would not know what we are buying and what it contains. Just as organic food are clearly labelled gm foods must be too. I hope this helps you. while correct the above answer is relevant in Europe. in the US most corn and soybeans are GM and have been for years
panel discusion
Probably. Because genetically modified foods (GMO) are not required to be labeled as such, it is difficult to know for certain. But it is very likely that food staples produced by huge corporations such as Monsanto or Cargil are genetically modified. I suspect most of the corn, soybeans and wheat produced in the U.S. are GMO.
Assuming that you mean the first crop with non-natural genetic material inserted artificially by humans, the first genetically modified crop was tobacco, with the first plants having been created in 1982.
Every life form is probably the product of accidental mutations! Nowadays mutations are not necessarily accidental--they are called genetically modified organisms (GMOs).
First you must specify whether you mean GM foods that are modified by gene replacement in the lab or by selection and hybridization. Because of the stigma given GMO's by pseudo scientists there are very few directly grown, non processed GM foods. Almost all soybeans grown in the US are GMO and most of the corn and canola. Sweet corn, however, is not GM, but it's a hybrid. Growers must use herbicides to control weeds because there is no GM seed to do it.
Genetically modified food is so cheap because the processes used in growing it is supposedly "faster, better, and cheaper." Most soybeans, which are in most of the foods we consume, are genetically modified and nobody really knows. Companies just want to grow more for cheap then sell more at a cheap price.
There is no genetically modified, or altered, wheat on the market as of March 2013. That is not to say that it won't happen in the future. Oats are also not genetically modified. Most baking ingredients are not genetically modified. Look for 100% wheat products to be sure. There are also lists of products and companies that do, and do not, use GMOs in their food.
Genetically modified food can also be achieved by altering their DNA (or genes) by genetic engineering techniques. This usually involves inserting a gene into the organisms' DNA to create a certain trait. For example, some corn crops have been genetically modified so that they become more resistant to herbicides and insect pests. In most countries Genetically Modified foods (GM) as well as foods containing GM source foods have to be labelled by law, giving consumers the choice to use them or not. Agriculturally speaking the opposite of GM foods are "Organic" crops.
By GM, you probably mean genetically modified. That means the chicken's DNA has been modified to make it "better". A typical improvement is faster than average growth rate. The normal chicken has not been genetically modified. Organic chickens are not only not genetically modified themselves, but are fed food that has not been genetically modified either. These are considered the healthiest, but are also the most expensive. The GM has nothing to do with General Motors.
GMO: genetically modified organisms. Genetically Modified Organisms are created by taking Genetic Material from 2 different sources and combining them into one molecule. They're created by taking certain traits from the organism they came from and supposedly make something else better. The first patented GMO was created to help clean up oil spills.
One of the most known documentary on genetically modified food is Panacea or Poison. Another film that is more of an "internet sensation" than an actual film is "Controlling Our Food".
Corn is a prime example. It has been genetically modified, and then processed into high fructose corn syrups, which are then used as sweeteners in multiple products, including soft drinks, cereals, candy and candy bars, and many other sweets and sweetened foods.
