Viking settlers are believed to have brought the knowledge of how to make skyr with them from Norway to Iceland. But, the art of skyr—making has been lost in Scandinavia. Skyr is still a very popular product in Iceland, a country with the world’s second longest life expectancy.Skyr looks and tastes like Greek yogurt. It’s made with skim milk, so it’s naturally very low in sugar and is fat-free. It’s also an excellent source of protein and calcium. Much of the lactose is consumed by the bacteria, so it can be consumed by people who are lactose sensitive.The special bacteria culture also gives skyr its taste and makes it full of healthy probiotics.
