Burning more calories and fighting cancer are all because of the ingredients contained in tea: polyphenols and theobromine.

Tea polyphenols (especially those in green tea) can be used for antioxidation, pathological changes and pathogenicity. Scientists extract tea polyphenols from green tea.

However, an Australian study (which surveyed 65,438+0,500 women aged 70-85) concluded that drinking tea can really protect the hip health of elderly women, in other words, it can protect postmenopausal women from osteopetrosis. Similar studies in Turkey, New Zealand, the United States, Iran, Japan and China have confirmed the benefits of tea in protecting bone health. Therefore, the hypothesis that tea and coffee can cause calcium deficiency in bones is not established. Moreover, catechins and quercetin in tea can bring more benefits than caffeine.
