A “Polyphenol-rich diet decreases cardiovascular risk. LDL oxidation is the primary event in atherosclerosis plaque formation and antioxidants such as polyphenols were shown to inhibit LDL oxidation and atherosclerosis development.” Incorporating more Polyphenols into your diet would be wise. No surprise, Yerba Mate is loaded with Polyphenols (Kawakami, A. Kabayashi 1991).
“Given the growing importance of flavonoids such as quercetin, rutin, and catechins as putative modulators of LDL oxidation, and in some systems as inhibitors of genotoxicity, herbs with a high concentration of these compounds and widespread ethnopharmacological use are of special interest. One of them is Ilex paraguariensis [Yerba Mate].” (Gugliucci*, N. Bracesco, et al., 2002)
Bixby, et. al. confirmed yerba mate tea as the most effective source of flavonoids. Their laboratory tests confirmed that “flavonoid rich beverages could represent an alternative coadjuvant in treatment. In this regard, our studies suggest that Ilex paraguariensis extracts [Yerba Mate via the Traditional Method] are more effective than either green tea or red wines.” (Life Sciences, 2005, #77 pgs 345-358)
Yerba Mate tea drunk with the gourd and bomilla is loaded with antioxidants. WebMD notes: “The detoxifying effect of these antioxidants protects cells from free radicals, the damage that can lead to blood clot formation, atherosclerosis, and cancer," says Weisburger. The bulk of research shows that regular tea drinkers, people who drink two cups or more a day, have less heart disease and stroke, lower total and LDL (often called “bad”) cholesterol, and that they recover from heart attacks faster.”
