Argentine's daily diet is mainly meat, and vegetables are rarely eaten. However, the prevalence of hypertension in Argentina is very low in the world, because yerba mate contains a lot of alkaloids and vitamin C.

It helps protein to be converted into sugar, which is easily absorbed by human body, helps blood circulation, lowers blood pressure, and promotes digestion and metabolism.
