Our preoccupation with all things health holds huge opportunity, believes Danone, as demand grows for high-protein products and probiotics. Having unveiled its low-calorie, zero-sugar Light & Free brand in 2016, Danone jumped on the skyr bandwagon last month with the launch of the Icelandic-style yoghurt under the same range, with no added sugar but 14g of protein. And its Activia range now includes spelt, oats and quinoa, as well as rhubarb, prune and fig flavours.
