Study: Black tea helps keep bones healthy

Researchers in Japan said black tea could help treat osteoporosis, a bone condition affecting older people, but admit you need to drink an awful lot of it.

Scientists said the humble brew contains an antioxidant that can prevent the loss of bone density commonly seen in old age that makes the elderly more vulnerable to fractures.

The news is the latest claim for a drink that is a staple of countries around the world, and one over which never-ending arguments rage about how to brew the perfect cup.
