The difference between low-fat milk and pure milk is mainly the difference in fat content. Low-fat milk has a lower fat content and pure milk has a higher fat content. If you are overweight and have high blood lipids, it is better to drink some low-fat milk as much as possible. However, if the weight is normal and there is no abnormality in blood lipids, you can usually drink some pure milk normally, which can also play a role in supplementing nutrition. The nutritional value of milk is relatively high, so it is recommended to apply it every day, which can increase immunity and enhance resistance.
