Why did the vikings drinked buttermilk?

Answer 1

Vikings drank buttermilk primarily for its nutritional benefits and to aid digestion. It was a rich source of probiotics, helping to promote gut health, which was particularly important in their time when food preservation methods were limited. Additionally, buttermilk was a practical choice in their diet, as it was often made from leftover milk after churning butter, reducing waste. It also provided hydration and energy during long voyages and harsh winters.
