Oats have long been considered a very healthy grain. Oat grain is rich in fiber and has a large amount of vitamins and microelements. Oatmeal dishes lower cholesterol levels and give you energy. Oats also contain thiamine, a substance that is converted into the happiness hormone. Most often, oatmeal is prepared with milk, but porridge with water is more suitable for dieters. If you supplement oatmeal with vegetables, you can serve it not only for breakfast, but also as a side dish for lunch.
