Wheat, oats, rye and barley - grain-based foods are very nutritious with many health benefits. What's more, they are a very reasonably priced choice in food stores.
For hundreds of years, grain has played an important role for human life in the Nordic countries. For example, in the 18th Century when food was scarce, grain, in the form of gruel, porridge and bread, made up around 80 percent of diets. We used to eat a lot of rye and barley, but little wheat. Today, however, wheat is the most common cereal in the Nordic countries.
Even today, grain is a very important staple food that is grown in almost half the total cultivated land in the world.
