You shouldn’t buy your tortillas at the supermarket


The vast majority of tortillas in the supermarket are made with this type of flours

Corn is part of our life, our worldview, ritual life, tradition, and culture. Therefore, the tortilla is a fundamental part of our diet. As Mexicans, we use it for everything: in tacos, quesadillas, tortilla chips, tostadas, and sometimes even as a cover. We were born and raised with it, whatever our social class.

But from a couple of decades to date, the presence of genetically modified corn companies such as Gruma / Maseca has taken great strength. Therefore, the tortilla and its derivatives underwent severe changes. These large companies offered “better corn,” advanced technology, facilities, and even job opportunities. What we didn’t know is that we were signing a pact with the devil.

But what does this have to do with tortillas at the supermarket? Well, currently 70% of the tortillas produced in Mexico are made with Maseca “corn flour” (Gruma’s main brand) which is present not only in supermarkets but also in tortilla shops on every corner.

Corn sowing

According to a report by the Association of Organic Consumers, in three out of eight samples of Maseca modified cornflour. ”The Association of Organic Consumers (ACO) announced today that samples of white and yellow corn flour of the Maseca brand tested positive in glyphosate residues and its main metabolite, AMPA. Glyphosate is the active ingredient in Monsanto’s herbicide, Roundup. ” This results in poor quality corn that is harmful to health. Basically GMO-packed corn.

The vast majority of tortillas in the supermarket are made with this type of flours. But this is not about a single company, it is about many corn flour companies that use additives, colorants, flavorings, and countless chemicals to make tortillas “last longer.”


Cornmeal is not corn. The best effort we can do to take care of our health is to buy nixtamalized tortillas from a mill that does not use corn that was genetically modified.
