You can use cold milk or hot milk to brew oatmeal in normal times. If it is hot milk, the temperature should not exceed 60 degrees, because the milk temperature is too high, the nutrients will be lost. If you have a bad stomach, it is not recommended to use cold milk directly to brew cereal, which is easy to bring gastric stimulation. The oatmeal itself is hard and a little rough, if soaked in hot milk, the expansion time will be shortened, but if soaked in cold milk, the time may be longer, because if it is not sufficiently soaked, the oatmeal will not taste good and it will be a little bit hard, so if it is soaked for a long time, it will be softer, and it will help the oatmeal to fully absorb the yogurt. Soaking oatmeal in milk is nutritious and provides energy for the body, and if you add some mixed nuts, the flavor and nutrition will be better.
In addition, it is best to use pure milk to soak oatmeal with milk, pure milk without too many additives. Oatmeal is low in calories and satiating, suitable for people who are losing weight. If you add milk to oatmeal, you can give your body protein, which is exactly what dieters need.
