Genetically modified organisms (GMOs) can be defined as organisms (i.e. plants, animals or microorganisms) in which the genetic material (DNA) has been altered in a way that does not occur naturally during mating or natural recombination.
The technology is often called “modern biotechnology” or “genetic engineering”.
It allows selected individual genes to be transferred from one organism and into another, as well as between nonrelated species.
For example, a GM tomato, containing the fish gene that is invisible to the eye, can provoke an allergic reaction
GM foods are developed and marketed because there is some perceived advantage either to the producer or consumer of these foods.
The GM products are usually the products with the comparative lower price and or greater benefit (in terms of durability or nutritional value).
Are GM foods safe?
Different GM organisms include different genes inserted in different ways. This means that individual GM foods and their safety should be assessed on a case-by-case basis;
it is not possible to make general statements on the safety of all GM foods.
The GM foods currently available on the international market have passed safety assessments and are not likely to present risks to human health.
In addition, no effects on human health have been shown as a result of the consumption of such foods by the general population in the countries where they have been approved.
Genetically modified organisms do not only grow, like their predecessors, but also survive where older varieties were killed due to varying weather conditions.
Many of them are not affected by unexpected frost, flood or drought.
Some plants have begun to have such a developed root system, which allows them to retain the maximum amount of moisture.
And those varieties that were previously sensitive to lower temperatures became more resistant to them.
Also, new fast-growing varieties of grain crops were created.
Genetic changes are carried out in order to give the plant useful properties:
• resistance to pests, frost, extreme environmental changes, etc;
• the ability to meet the demands of the continuous population increase. Genetically modified products are designed to save the world's growing population from hunger;
• the ability to protect themselves from insects and weeds, thereby reducing the cost of production;
• the ability of such vegetables and fruits to resist viruses, bacteria and other infectious organisms;
• Some tree species are bred specifically for the destruction of pollution.
Well, the other side of the coin ... Why do many oppose GM products?
• Most countries do not have laws regulating the production and consumption of GM foods. Therefore, knowledge of the process is very limited. No one really knows what exactly they are consuming.
• Consumers do not know what they are buying, and do not know how it affects their health. For example, a gene from a snowdrop, embedded in potatoes for resistance to the Colorado beetle, causes an increased content of plant lectins, which is unfavorable for mammals.
From such a product, the immune system and the intestines suffer, and kidney, liver and brain diseases occur.
• On the goods, there is no information about the substances contained in the products, or their quantity.
• In addition, there is also food risk as some foods can cause an allergic reaction. For example, a GM tomato, containing the fish gene that is invisible to the eye, can provoke an allergic reaction in a person to whom the fish is contraindicated.
This statistic shows the biggest producers of genetically modified (GM) crops in 2015, based on planted acreage. In Brazil, GM crops were cultivated on an area of about 44.2 million hectares in that year.
The fears behind genetically modified crops seem to be more about control over the food chain more than anything else.
People want to know how their foods are made. They desire knowledge about the engineering process so they can know what is being processed by their digestive tracts.
Maybe, if we all had more readily available information about what was really in these foods and what exactly is being eaten, their acceptance would be more common.
