Some people say that spinach is rich in oxalic acid, which will affect the body's absorption of calcium, so it is easy to lead to calcium deficiency, which will lead to cramps. In fact, there is a lot of oxalic acid in water spinach, but most vegetables and fruits in our daily diet contain oxalic acid, which is a self-protection mechanism of plants. Oxalic acid tastes sour and is high in wild plants to prevent it from being eaten by other animals.
Vegetables with high oxalic acid content in life, such as spinach, amaranth, leek and bamboo shoots. If water spinach is called a narrow vegetable because of its high oxalic acid content, then the above vegetables should all belong to narrow vegetables.
Secondly, when we eat these vegetables, we will heat and cook them before eating them. In this process, oxalic acid will lose a large part, so we don't have to worry about it, and we can't eat it in pounds.
So excluding this statement, are other factors easy to cause cramps? From the point of view of traditional Chinese medicine, water spinach is cold. If eaten in large quantities, it is really not suitable for people with weak constitution, which may also be the reason why some people eat too much and are prone to cramps. But people who may cramp may also be calcium deficient, but there are still many people who have eaten spinach for decades without cramping.
Therefore, for people who will cramp after eating spinach, don't eat too much at a time, and pay attention to proper calcium supplementation and sun exposure to relieve cramps.
