The French public research institute, Institut Nationale de la Recherche Agronomique (INRA) has produced some interesting findings on healthy fats in milk.

Researchers in the INRA-INSERM-University Aix-Marseilles Joint Research Unit for Human Nutrition and Lipids: Bioavailability, Metabolism and Regulation, wished to compare the effects on the cardiovascular risk of two types of dairy fats: those produced by silage-fed cows (winter type) and those produced by grazing cows (summer type).

The fatty acid profile of milk from cows was shown to vary significantly between the two feed groups, with “summer milk” resulting in 25% less fatty deposits found in the aorta of hamsters used in the trial. The results from the study provide essential data to determine whether in man, as in the hamster, the fatty acid composition of milk fat can be optimised in the context of efforts to prevent cardiovascular disease.
