O consumo de chá-verde (Camellia sinensis) como fator adjuvante no controle do diabetes mellitus: Evidências Baseadas em Metanálise.

Abstract

Diabetes mellitus and other categories of impaired glucose tolerance are frequent in the adult population and are associated with an increased risk for cardiovascular disease and microvascular complications. Tea is the most consumed beverage in the world after water. Green tea contains catechins, potent in vitro and in vivo antioxidants. Recent human studies suggest that green tea can help reduce the risk of cardiovascular disease and some forms of cancer, as well as promote other health benefits such as hypoglycemic effect, body weight control, protection against ultraviolet rays and maintenance of bone mineral density. The growing interest in their benefits led of green tea to be used as a functional food for diabetic patients. A literature search was performed in PubMed. Of the 172 studies initially identified, 12 studies were included in this meta-analysis after applying the inclusion and exclusion criteria. In total, 824 patients (females 57.2%, males 42.8%) were included. Results shows a slightly effect of green-tea consumption on glycemic index of diabetic’s patients. Despite all the promising evidence about functional properties of green tea on non-transmissible chronic diseases, further investigations are necessary to fully understand its real contribution to human health.
