More on mate tea: lower cholesterol and an international agreement

Public release date: 23-Oct-2007

When a study in her lab showed that mate (mah’ tā) tea drinkers had experienced a significant increase in the activity of an enzyme that promotes HDL (good) cholesterol while lowering LDL (bad) cholesterol, University of Illinois scientist Elvira de Mejia headed for Argentina where mate tea has been grown and taken medicinally for centuries.

In the cholesterol study, blood levels of the cardio-protective enzyme paraoxonase-1 were measured before and after healthy volunteers consumed either 0.5 liters of mate tea, milk, or coffee. Activity of the enzyme increased an average of 10 percent for mate tea drinkers compared to the other drinks.

Heck characterized the tea consumed in the cholesterol study in de Mejia’s U of I labs and is now working with the tea brought back from Argentina. He said that mate is high in xanthines (mainly caffeine), and he has found 12 polyphenolic compounds at different concentrations, depending on where the tea was grown. Polyphenols are thought to have a protective effect against cancer and cardiovascular disease
