Nutrition profile

100 g of rolled oats (dry) contains roughly 380 kcal, 13 g of protein and 10 g of fibre. The values are approximate averages. What sets oats apart from other grains is that they contain a type of soluble fibre called beta-glucan; on contact with water it forms a gel-like consistency, and that gives porridge its familiar texture.

Practical uses

The classic use is porridge cooked with milk or water. Overnight oats, prepared the evening before, are a practical alternative for anyone short of time in the morning: the oats are mixed with yoghurt or milk and left in the fridge. Topping them with fruit, walnuts or almonds makes the meal fuller. Ground into flour, oats can also be used in baking.

A note on gluten, and storage

Oats themselves contain no gluten, but because most facilities also handle wheat on shared lines, products can be contaminated with it. People with coeliac disease should choose certified products labelled "gluten free" and discuss the matter with their doctor. Dry rolled oats keep for months in a sealed container in a cool, dry place, while cooked porridge is best eaten from the fridge within a few days.
