Studies confirm the benefits of “yerba mate” tea on cholesterol

October 24th, 2007 by admin

University of Illinois scientist Elvira de Mejia conducted a study that showed that mate tea drinkers increased the activity of enzymes that improve HDL (good) cholesterol and lower LDL (bad) cholesterol. “Yerba mate” is a traditional infusion drunk in Argentina, Uruguay, Paraguay and regions of Chile and Brazil. “Ilex paraguayensis, the mate plant has been grown and consumed for centuries. Dr Mejia has signed a five-year agreement with La Universidad Nacional de Misiones (UNaM, national University of Misiones) to carry out a collaborative study to assess 84 genotypes of mate tea for their ability to provide benefits on cholesterol and other health factors. Both cultivated and wild varieties will be included in the study.

In the September issue of the specialized journal Planta Medica, Dr mejia said that their studies show that some of the most important antioxidant enzymes in the body experience induction by this mate herbal tea, and since Argentina has so many different mate varieties, they’ll perform more comparisons between the various genotypes. They’ll be also able to explore the benefits of cultivating under different conditions.

The aim is not only identifying the most beneficial genotypes of the herbal tea in terms of nutrition value, but also help Argentine producers to improve drying and processing of mate tea to achieve better extraction of the tea’s bioactive compounds.

“Food companies are very interested in adding tea extracts to juices, soda, and even beer to increase the nutritional value of their products,” she said.
