10 Feb 2020 --- Dairy that has been naturally modified to be lower in saturated fat can benefit blood cholesterol and heart health. This is according to a new study from the University of Reading in the UK, which compared ultra-high temperature processing (UHT) milk, cheese and butter from cows fed vegetable oil with dairy products from cows on a standard diet. By consuming a diet containing fatty acids similar to olive oil, the cows produced milk that replaced 25 percent of saturated fat with monounsaturated fat. The study was supplied with products from Arla Foods UK and AAK UK.
