Contrary to popular belief, Whey Protein Isolate (WPI) is not going to make you ‘bulk up’ and athleticism is not a prerequisite for its consumption. Having said this, not all protein powders are created equal. Firstly, let’s understand what it is….
The curd in dairy is used for making cheese, while the liquid component, known as whey, is separated from the curd and is put through a micro-filter to remove the lactose and casein – two things many of us don’t digest well – and you’re left with the valuable amino acids and calcium. Whey Protein is possesses the highest biological value of all known Foods (the biological value of well-manufactured Whey Protein is 110-159 on a scale of 1-100). It has many immune-boosting properties, it can slow the process of sarcopenia (muscle loss as we age – see the chart below), lower triglycerides (fats in our blood), boost glutathione levels (powerful antioxidant), boost calcium intake, help to control our weight and keep us feeling fuller for longer.
