DNA from other organisms, whether genetically modified or not. The acquisition of DNA by the human body from a genetically modified plant is also impossible due to the fact that it is broken down by enzymes upon contact with the skin or the inside of the stomach. DNA broken down into individual nitrogenous bases that make up genes becomes an ordinary food ingredient . Therefore, it cannot continue to perform its previous functions. Foods and cosmetics containing GMOs can cause allergies By law, each new genetic modification of plants is tested in terms of causing allergies before being introduced into regular cultivation. For example, a food allergy is an exaggerated reaction of the human body to certain ingredients found in food. Most of the time, allergy symptoms and sensitization are caused by proteins that the allergic person's body 'thinks' are pathogens and tries to fight off. This results in an allergic reaction that can take the form of gastrointestinal discomfort, breathing problems, or skin lesions. Therefore, allergies can be caused by both GMOs and conventionally grown plants, since both contain proteins. Foods and cosmetics containing GMOs pose cancer risk In 2012, a study was published according to which feeding rats genetically modified corn grown with a pesticide called glyphosate caused tumors in these animals . The author of that study was Gilles-Éric Séralini, a French molecular biologist who is one of the staunchest opponents of GMOs. The professor was quickly proven wrong in his research, even with respect to methodology.
The scientist conducted tests on breeds that are susceptible to cancer . Furthermore, he did not use a control group . The scientific community considered this a cardinal mistake because the lack of a control group does not provide a reference point. This, of course, entails the impossibility of reliably assessing an increase or decrease in the frequency of any specific consequence. Another mistake of the teacher CZ Leads was insufficiently large test groups . In other words, his calculations did not have a reliable statistical effect . The scientist's publication was eventually retracted as an unreliable scientific source. Unfortunately, Séralini's findings remain to this day the main argument of fierce opponents of GMOs. Proponents, on the other hand, have on their side the many years of reliable studies proving the absence of carcinogenic potential in genetically modified plants and therefore in raw materials derived from them, including cosmetic raw materials. Additionally, some genetic modifications have the ability to reduce human exposure to carcinogens . Examples include modified corn varieties resistant to mold fungi and harmful aflatoxins. GMOs kill beneficial insects that pollinate plants New generation plant metabolites have the ability to act selectively . As a result, they control pests without showing the slightest harmful effect on the bees.
Some substances produced from genetically modified plants do not reach pollen or nectar. Other GMO derivatives, despite being found in pollen, are completely harmless to bees and other animal species, with the exception of pests that attack agricultural plants. GMOs lead to increased use of pesticides The very idea of GMOs involves reducing, not increasing, the use of pesticides in plant cultivation. GM crops are intended to be more resistant to weeds, pests and diseases, compared to conventional plants. Creating genetically modified plants actually protects crops from various pathogens without harming any beneficial organisms. Most modified plant lines demonstrate high resistance to herbicides , i.e. herbicides. In practice, this means that herbicide treatments are not harmful to crops, while selectively destroying weeds. However, the excessive use of pesticides in plant cultivation means that, over time, weeds become resistant to chemicals, becoming extremely difficult species to control. This is a dangerous phenomenon, especially since in some regions of the world (e.g., USA) herbicide use is increasing year after year. Therefore, the emergence of 'superweeds' is wrongly attributed to GMO varieties, while the continued increase in the use of certain pesticides can have a negative impact on plants, soil and water quality/purity.
