In Argentina and other South American countries, consumption of yerba mate (Ilex paraguariensis) tea exceeds that of coffee or tea (Camellia sinensis). The prevalence of osteoporosis and the incidence of osteoporotic fractures in Latin America are lower than in Northern Europe and the United States, but they are increasing....Woo-woo.
Intake of caffeine, which is present in high concentration in yerba mate, may negatively affect bone mineral density (BMD) and fracture risk. Previous studies have not examined the effects of yerba mate on bone health. The objective of this study by Conforti and colleagues was to assess the effects of yerba mate consumption on BMD...
The authors conclude that chronic consumption of yerba mate tea was associated with greater BMD at the lumbar spine and femoral neck, "suggesting a protective effect of this tea on bone mass of postmenopausal women." They also note that their earlier hypothesis that yerba mate consumption, based on other investigators' reports of a deleterious effect of caffeine on BMD, "should be rejected."
Limitations of the study are its retrospective nature, participants' self-reports of yerba mate consumption, and that the study participants were a selected population of postmenopausal women in a program for the prevention, diagnosis, and treatment of osteoporosis. Results may not be generalizable to younger women, men, or children.
Meaninglessly impractical k-rap.
