Readers who remember the days of compulsory milk at school were probably getting an unforeseen benefit.
Scientists at the University of Otago have found that regular consumption of school milk significantly reduced the risk of bowel cancer in adulthood. The national study, published in the American Journal of Epidemiology, found that the risk of bowel cancer was 30 per cent lower in people who drank school milk daily during the period 1937-1967. Researchers believe this is due to the calcium in the milk.
