Here is interesting material on some of the problems vegans face, this time the likelihood of bones breaking.

“A study by academics at the University of Oxford found that vegans have more than double the risk of suffering a broken hip than meat eaters, with the affliction common in older people, especially women

A study of more than 50,000 British people tracked over two decades found giving up animal flesh weakens bones - and can trigger osteoporosis.

Compared with people who ate meat and fish, scientists found that those with lower calcium and protein intake were especially prone to hip, leg and spine fractures.

Vegans were also 43 per cent more likely to suffer a fracture anywhere. In particular this applied to the leg, vertebrae and collarbone.

The latest research by the Vegan Society says there are now 600,000 vegans in Britain.

Study lead author Dr Tammy Tong, an Oxford University nutritional epidemiologist, said: "The biggest differences were for hip fractures, where the risk in vegans was 2.3 times higher than in people who ate meat - equivalent to 15 more cases per 1,000 people over 10 years."

So, the answer is to not be a vegan if you want to have strength, and if red meat is not your thing, then at a minimum open up some tins of cheap tuna or salmon, and down it with your veges.
