Because cucumber contains a vitamin C decomposing enzyme, it will destroy vitamin C in other vegetables. The more vitamin C content in food, the more serious it is destroyed by decomposing enzymes in cucumber. Tomatoes are typical vegetables rich in vitamin C. If we eat them together, the vitamin C we take from tomatoes will be destroyed by the decomposing enzymes in cucumbers, and the nutritional supplement effect will not be achieved at all. In addition, peppers, cauliflower, bitter gourd and other vegetables also contain more vitamin C. It is best not to eat them with cucumbers.

However, from the cucumber itself, it is a delicious and nutritious vegetable. Cucumber contains protein, fat, sugar, vitamins, cellulose, calcium, phosphorus, iron, potassium, sodium and magnesium. In particular, the micro-cellulose contained in cucumber can reduce the contents of cholesterol and triglyceride in blood, promote intestinal peristalsis, accelerate waste excretion and improve human metabolism. Propionic acid contained in fresh cucumber can also effectively inhibit the conversion of sugar into fat. Therefore, eating cucumber often can reduce weight and prevent coronary heart disease.
