Should every cow carry a health warning?

25 Ebrill 2007

Two eminent Cardiff University professors go head to head this week (Thursday April 26) debating the risks and benefits of drinking milk.

Professor Tony Campbell and Professor Peter Elwood, both from the University’s School of Medicine, have deeply different views about cow’s milk.

Professor Campbell, a medical biochemist, has claimed that a wide range of previously unexplained health conditions can be attributed to a common intolerance to milk.

Among the symptoms he says can be triggered are: migraine, irritable bowel, chronic fatigue, loss of concentration, severe tiredness, eczema, hay fever, muscle, joint and gut pains.

Professor Campbell said: "Certainly milk contains good things for healthy living — protein, vitamins, calcium and so on. But milk also contains lactose, a unique ingredient that can be harmful".

Meanwhile, Professor Elwood has found that people who drink the most milk have a lower risk of heart disease, stroke and diabetes than those who drink little or no milk. His study tracked more than 400,000 adults worldwide for up to 28 years.

Professor Elwood said: "The general perception of milk is that it raises cholesterol and therefore increases the risk of heart disease. Evidence on the actual incidence of heart and other life-threatening diseases in large-scale, long-term studies shows this is a totally misleading view. In fact, the consumption of milk and dairy foods appears to confer a considerable survival advantage."

The debate, Should every cow carry a health warning? will take place on Thursday 26 April as part of Cardiff University’s series of Science in Health public lectures in the School of Medicine, Heath Park, Cardiff, at 7.30pm.

All Cardiff University Science in Health lectures are free and open to the public, with no booking necessary. Everyone is welcome, particularly senior school pupils interested in healthcare.
