A new study by the University of Newcastle has said that
organically reared cows that eat fresh grass are more likely to provide
healthier milk. Researchers at the Danish Institute for Agricultural Science
also collaborated on this study.
The study says that omega-3 and conjugated linoleic acid
known as CLA9 , which are essential fatty acids, are present in higher levels

"Our work has not looked at the impact on human health,
but I would say organic milk should be better for health from what we know of

Group. "They are effective in combating cancer, coronary heart disease and type
