MODEL RELEASED. Collecting milk sample. Researcher collecting a milk sample in a milking parlour. It will be used to test the health benefits of conjugated linoleic acid (CLA), a fat found naturally in milk. Scientists at the Universities of Southampton and Reading, England, are testing whether increasing dietary CLA intake can enhance the human immune system. CLA may help the body to fight bacterial and viral infections. It could also act as an anti-cancer agent, by stimulating the immune system to destroy tumours. If its health benefits are proven, CLA levels in milk could be enriched, by adding CLA to cattle feeds. (KEYSTONE/SCIENCE PHOTO LIBRARY/JAMES KING-HOLMES)
