Choosing Organic Milk Over Normal Milk Can Offset Climatic Change
Choosing organic milk over conventional milk is the right choice. Yes, according to research at the Newcastle University, changes in the weather conditions can have a harmful affect on the conventional milk consumed. The study published in the January issue of the Journal of Dairy Science highlighted the beneficial facts of organic milk.
The samples to study organic milk for climate change were collected during a poor summer and winter seasons. The organic milk contained higher levels of saturated fatty content and very low levels of good fatty acids. These levels when compared to the year that had normal weather conditions showed much variation in good fatty acids.
Researchers considered organic supermarket milk samples and found that they had higher levels of good fatty acids. These levels when compared with conventional milk were far too high, and they remained the same regardless of the changing weather conditions. Choosing organic milk proved to be beneficial through the year.
Importantly, the levels of fatty acids were consistent among various suppliers of organic milk. This was not the same with ordinary milk brands. Gillian Butler, the lead researcher, said benefits of organic milk at farms were more in summer season that in other seasons. Also, supermarket organic brands maintained a significant consistence levels in organic milk benefits.
The study said popular brands failed to maintain a consistent level in milk benefits. The samples revealed that cattle grazed on low fresh grass diet. This resulted in milk having low polyunsaturated fatty acids and Omega-3 levels. Moreover, the cows were given a saturated fatty acid obtained from palm oil.
In conventional farms, the grass is raised using fertilizers. In all organic farms, the grass is never treated with artificial fertilizers. Absence of nitrogen fertilizer helps in growth of red and white clover, which can alter fatty acids and milk composition.
Gillian Butler said there is a constant move to cut down consumption of saturated fatty acids. Therefore, choosing organic milk is right because they are high in antioxidants and other nutrients. Organic milk improves beneficial fatty acids in the body. The samples to study organic milk for climate change showed that saturated fats or bad fats in organic milk are reduced to almost 30-50 per cent. She believed that adverse weather conditions lead to changes in grazing periods and milk output. This may compel farmers to give cows’ higher concentrated feed supplements.
The research revealed a link between quality of milk and changing weather conditions. Farmers may have to change their dairy practices if cool and wet summers continue in future too.
The research conducted over a period of two years concluded that organic milk brands at supermarkets were high in beneficial fatty acids in summer and winter. The study is an offshoot of a previous research on differences between organic and ordinary milk on farms. Emma Hockridge of Soil Association said the study is a big boost to people who are choosing organic milk over ordinary milk.
