‘Scientists have bred cows that produce skimmed milk and hope to establish herds of the cattle to meet the demands of health-conscious consumers.
The milk is also high in omega3 oils, claimed to improve brain power, and contains polyunsaturated fat. The saturated fats found in normal milk are linked to increased risk of heart disease. The cows, which have a particular genetic mutation, were bred from a single female discovered by researchers when they screened milk from millions of cattle in New Zealand.
Butter from these cows has the extra advantage of being spreadable straight from the fridge, like margarine.’
