Cucumber contains vitamin C, vitamin B and many trace minerals. Rich in nutrition and crisp and refreshing when eaten raw. From the point of view of nutrition, cucumber skin is rich in nutrition and should be eaten raw. However, in order to prevent the harm of pesticide residues to human body, cucumber should be soaked in salt water 15-20 minutes before being washed and eaten raw. When soaking cucumbers in salt water, don't pinch your head and remove the roots. Keep the cucumber intact and avoid the loss of nutrients in the cut surface during soaking. In addition, cold salad should be cooked and eaten now, and it should not be put for a long time after it is done, which will also lead to the loss of vitamins.
