There is always an ingredient of the moment, a nutrition newcomer set to transform our health and our bodies for the better. And there’s no doubt that this year, protein reigns supreme. A Mintel report said that nearly one third of all food and drink launches in the last two years carry ‘high protein” claims on their labels, and one in five gym users told another survey that they take a protein supplement or snack of some sort in the belief it enhances their exercise. It’s hardly surprising it is cropping up in everything, from bread to ice cream and chocolate biscuits to cereals and crisps.
