Wetter, cooler summers can have a detrimental effect on the milk we drink, according to new research published by Newcastle University in England, Science Daily reports. Researchers found milk collected during a wet, cold UK summer and winter, had significantly higher saturated fat content and less beneficial fatty acids than in a more 'normal' year. But the scientists discovered organic supermarket milk showed higher levels of nutritionally beneficial fatty acids compared with 'ordinary' milk regardless of the time of year or weather conditions. "The study, which is published in this month's Journal of Dairy Science (January 2011), leads on from previous research undertaken nearly three years ago which looked at the difference between organic and conventional milk at its source -- on the farms," says Science Daily.
