I have been a full cream milk lover all my Iife but decided recently to try lite milk to see if there was a difference in flavour. I have to admit I can't tell the difference. The fat content of lite milk is almost half that of full cream so that is an added bonus.
I always buy low fat . I am very good at reading labels and I know the recommended levels of fat and sugar. There are foods that have low fat AND low sugar. You just have to read the labels per 100g serve. There is a website called calorieking and it helps to compare different brands.
