This myth started to be debunked as the result of a research work carried out by PhD. Verónica Di Loreto from Universidad Nacional de Rosario-
“ Thanks but the mate gives me stomach acidity”. “ Which yerba mate should I consume so as not to have gastritis?” Maybe you have heard these quotations as you were having a mate in a group.
However, this myth started to be debunked as the result of a research work carried out by Dr. Verónica Di Loreto from Universidad Nacional de Rosario, who found that the administration of Yerba Mate infusions to healthy laboratory rats does not cause lesions compatible with gastritis.
“We used Yerba Mate infusions via oral in different concentrations and for a period of 90 days. We did not find alterations in the gastric mucosa of the rats", the professional summarized, and then remarked that this experiment was carried out on healthy specimens.
“Gastritis - he recalled - is a multifactorial condition, in which stress, alcohol consumption, smoking and even genetic predisposition play a key role. "We can conclude that yerba mate infusions consumption per se would not produce alterations in the gastric mucosa in the absence of concomitant harmful factors".
Put it into simple terms: Yerba Mate does not harm healthy stomachs.
This research work was presented last August 16th in the “V Jornadas sobre Yerba Mate y Salud”, organized by the Instituto Nacional de la Yerba Mate ( INYM) and held at the Universidad Juan Agustín Maza (UMaza) from Mendoza, Argentina.
“The research project is divided into three parts. In the second stage, we aim at creating gastritis in lab rats while giving them yerba mate infusions and study whether the lesions are created in the presence of yerba mate or if the infusion improves or worsens the mucosal injury degree.”
In the third stage, once gastritis has been installed, we aim at studying if yerba mate influences injured mucose recovery. Therefore, learning if the quote “ I do not take mate, I suffer from gastritis” is true or not.
We also aim at studying the effect of the antioxidant properties of yerba mate on oxidative stress, one of the most important causes of gastric inflammation," said the researcher.
