How drinking tea can keep bones strong

Drinking three cups of tea a day could slash the risk of hip fractures by almost a third, the Daily Mail reports, citing a new study.

Scientists have said that the humble brew could become a powerful weapon against osteoporosis - a condition where the bones become brittle and fragile.

The study suggests healthy plant chemicals called flavonoids in black tea could help an ageing population ward off the bone-weakening illness.

For years, scientists have suspected these antioxidant chemicals help to reduce the risk of major illnesses like cancer and heart disease.

But the latest breakthrough points to drinking tea as a potent new way to protect the body's bones during the ageing process.

One in three women and one in 12 men in the UK develops osteoporosis at some point in their
lives - and it already affects around three million people.

Women who use steroid drugs, smoke, drink heavily and have a family history of the disease are most at risk.

But diet is also crucial and poor eating habits during youth are thought to increase the dangers of the disease later in life.

It progresses when osteoclasts, cells that break down old bone by removing the calcium and phosphorous that gives it strength, start to outnumber osteoblasts, rival cells responsible for making healthy new bone.

Right the way through life old bone is being destroyed by osteoclasts and new bone is formed by osteoblasts.

But after the ages of 30 to 35, there are fewer osteoblasts than osteoclasts.

Osteoporosis develops when the balance tips too far in favour of the osteoclasts.

This dramatically increases the risk of fractures to major joints like the hip.

Experts from the Sir Charles Gairdner Hospital in Perth, the Royal Perth Hospital and the Flinders University of South Australia in Adelaide, had read reports that tea might improve bone density.

But they wanted to see if drinking more of it lead to fewer fractures in elderly women.

They studied almost 1,200 women in their seventies over a ten-year period.
 

Each one was quizzed on their tea drinking habits and then closely monitored to see if they suffered a major fracture due to osteoporosis over the next decade.

During that period 288 of the women fell and broke a bone and nearly half involved a hip fracture.

The results showed that those women who drank three or more cups of tea every day were 30 per cent less likely to have suffered a break than those who drank less than one cup of tea a week.

In a report on their findings the researchers aid that every cup of tea the women drank each day appeared to cut the risk of a fracture by around nine per cent.
