Mexico City – What we eat is the leading cause of cancer risk, above tobacco consumption and infections, warned Magda Carvajal Moreno, a researcher at the Institute of Biology (IB) of National Autonomous University of Mexico (UNAM), which for several years studied the aflatoxins carcinogenic substances that we ingest daily in food.
The specialist explained that aflatoxins are secondary metabolites of the fungus Aspergillus flavus, found in various foods such as corn, rice, peanuts, nuts, pistachios, peppers, chicken, egg, milk , sausages and also in beer.
Aflatoxins are produced and consume with contaminated food, accumulate for years in deoxyribonucleic acid (DNA) and generate various harmful effects, such as cancer and mutations.
At a conference on In the Permanent Seminar on Agriculture, Food and Nutrition (SPAAN) of the University Food Program (Pual), Carvajal Moreno said that what we eat is the leading cause of cancer risk, with 36% chance, including ] of tobacco use, which accounts for 31% and has been warned of its adverse health effects on many occasions, while infections occupy only third place, with 11%.
In a previous study, the researcher found that among the cases of liver tumors, 65% had aflatoxins; colon, 54%; rectum, 57%; pancreas, 46%; 60%: "In the latter case, there is a higher risk of suffering of 6.1% [cáncer] if the adducts to aflatoxin-DNA are present," he said.
Mexican and carcinogenic. According to what the researcher mentioned, some of the main ingredients of Mexican food are among the foods that are contaminated with aflatoxins: corn
Alerted that, for example, tortillas and their derivatives They are highly contaminated According to a recent study that she developed in Mexico City, 95% white corn and 60% corn, such as tortilla chips, sopes and tamales, quesadillas, among other typical Mexican dishes.
He noticed that the aflatoxins generated by the mold of the asp rgillus flavus, which reproduces easily in poorly stored grains, "are not seen, have neither taste nor smell , are heat resistant [soportan entre 260 y 320 grados sin descomponerse] and processes such as cooking, ultra pasteurization, nixtamalization and fermentation. "In addition, they are insoluble in water and in organic solvents such as methanol, ethanol, benzene and chloroform.
Carvajal Moreno explains that these metabolites are associated with cancer of the liver, pancreas, lung, colorectal and cervix of the uterus: "Although they act in one millionth of milligrams, they are the most potent known biological carcinogens.We are all born with latent proto-oncogenes, and aflatoxins, by a chemical mechanism of oxidation, turn them into oncogenes [cancerígenos] which accumulate during years in the DNA and mutate, mainly in individuals with a genetic predisposition. "In the first phase, aflatoxins are still eliminated by the body through the urine, but the danger increases when & # 39; 39, they are ingested daily.For example, if a person consumes food contaminated for 40 years, the substance gradually attaches to DNA and damage.
The specialist reported a in repair, replication and integration. so that once the gene is mutated, the process is irreversible and the cancer process begins after which the cell is transformed and the primary malignant tumor arrives, where the doctors must already intervene to counter it with treatment [19659004] There is a way to counter their damage to the fungus, and for this, it is recommended to eat probiotic foods such as blackberries, green and red peppers, spinach, broccoli, beets, cherries, green beans, tomatoes and the carrot.
Concluded that it is difficult to change dietary habits, but that it is possible to provide healthy products with adequate storage, dry and cold. [196590] 04]
