Processed milk is better
Speaking of healthy food, the milk that most people consume in their daily lives does not come directly from dairy farms. While being transported to retailers, hawkers and processing plants, it gathers all kinds of bacteria making it harmful for direct consumption. To get rid of these organisms and disease vectors, the milk needs to be heated at high temperatures.
A traditional way of doing so is by boiling the milk at home, a common practice followed by most households in Pakistan. What we do not realize is that boiling milk on our kitchen stoves takes time, and while we do manage to get rid of some of the bacteria, the prolonged heating makes the milk less nutritious by destroying most proteins and vitamins at the same time. On the contrary, factory-processed milk goes through UHT (Ultra High Temperature) treatment, where milk is heated at around 135°C for just over 2-4 seconds. The high temperature kills 99% of all bacteria while retaining the nutrients. Thus processed milk is far healthier and more nutritious as compared to loose milk.
