What does gmo mean with food

Since the beginning of agriculture, farmers have used selective breeding to grow the best crops. When selectively breeding, farmers replant only the seeds from the best crops with the desired traits.

Selective breeding is the reason we have many of the nutritious crops we know today. Modern genetic engineering allows farmers to choose the best traits faster and safer than ever before.

DNA is the blueprint for how organisms will grow and function. Genes carry out the blueprint. Some plants express beneficial genes, like drought resistance or insect resistance. Genetic engineering safely and accurately activates those beneficial genes or turns off the bad ones.

For example, many apples turn brown within minutes when cut into or opened, and this leads to food waste. Recent advances in genetic engineered have turned off that trait, creating an apple that doesn't brown as fast. All of this takes careful consideration of human and environmental health. GMOs are created to achieve a desired trait, such as resistance to a pest or tolerance to drought conditions.

For the most part, non-GMO on a product means that a product contains ingredients that suppliers claim are mostly GMO-free. Non-GMO labels , definitions, and verifications vary country by country. Some companies may use their own labels, calling an item non-GMO, without verification from an independent organization. A product could include as much as. The most widely grown genetically engineered crop varieties have been engineered to withstand the application of the herbicide glyphosate.

Glyphosate is a broad-spectrum herbicide which effectively kills or suppresses all plants, including grasses, perennials, vines, shrubs and trees. With genetically engineered glyphosate-tolerant crops, farmers can spray glyphosate directly on the crops, which would otherwise have been damaged or killed by the herbicide. The widespread use of glyphosate has led to the emergence of weeds that are resistant to it.

As of , roughly half of farms contain at least one glyphosate-tolerant species of weed, with more than a quarter having two or more glyphosate-tolerant weed species. This has led farmers to spray more glyphosate, and spray other herbicides as well, such as 2,4-D and dicamba. To address the continued development of glyphosate-tolerant weeds, chemical companies have developed a new wave of genetically engineered crops that tolerate the herbicide 2,4-D in addition to glyphosate.

Since glyphosate-tolerant crops were introduced commercially in , glyphosate use has risen almost fold globally. Glyphosate may also be harmful to human health. The decision, which has come under fire from the chemical industry, is based on limited evidence of carcinogenicity in humans for non-Hodgkin lymphoma, and convincing evidence that glyphosate also can cause cancer in laboratory animals.
