Organic milk lowers heart disease and cancer risk

London, May 28 (ANI): Organic milk may cut the risk of developing heart disease and cancer as compared to the normal milk from dairy farms, according to a new study.

The new study from Newcastle University has found cows grazing outside on grass and clover have rich quality milk because it has higher levels of beneficial fatty acids, antioxidants and vitamins.

The researchers also found that conjugated linoleic acid, which is thought to ward off cancer, was 60 per cent higher in organic milk during the summer than normal milk.

It had more omega-3 fatty acid and vitamin E, which are believed to reduce heart disease and cancer risk.

We have known for some time that what cows are fed has a big influence on milk quality, Daily Express quoted Gillian Butler, livestock production manager at Newcastle Universitys Nafferton Ecological Farming Group and lead researcher, as saying.

What is different about this research is it clearly shows that on organic farms, letting cows graze naturally, using a forage-based diet is the most important reason for the differences in organic and conventional milk.

As a result, our future research is focusing on how to improve the nutritional composition of milk during the winter, when cows are kept indoors and fed mainly on conserved forage.

I drink organic milk. It is still better, although the difference is not as great in the winter, she added.

The study conducted on 25 farms in South Wales and the North-east between August and October 2004 and January and March 2005 also revealed that natural grazing provided about 84 per cent of food for cows on organic farms in the summer, while conventionally farmed animals provided 37 per cent.
