In recent years, studies have found that calcium ions have a role in brain injury. Low blood calcium can cause muscle spasms and twitching of hands and feet due to increased neuromuscular excitability. At the same time, low blood calcium or a large number of calcium ions enter the cells, seriously interfering with the normal function of nerve cells, so that their excitability is increased and they are prone to discharge under weak stimuli, resulting in epileptic seizures. Calcium deficiency is one of the triggering factors for epilepsy, this is because in the blood of the human body, calcium ions have a very important physiological role, it can stabilize the nerve cell membrane, preventing the abnormal discharge activity of the membrane potential, and can reduce neuromuscular excitability, participate in muscle contraction, reduce the permeability of capillaries and cell membranes, and participate in the synthesis of transmitters within the cell. Experts summarize the classification of food containing high calcium: 1, dairy and dairy products: cow’s milk, goat’s milk and its milk powder, cheese, yogurt, condensed milk. 2, beans and soy products: soybeans, beans, lentils, fava beans, tofu, dried tofu, tofu skin, tofu milk and so on. 3, fish, shrimp, crab and seafood: carp, carp, silver carp, loach, shrimp, shrimp, shrimp, shrimp, crab, kelp, seaweed, clams, sea cucumbers, snails and so on. 4, meat and eggs: lamb, pork brains, chicken, eggs, duck eggs, quail eggs, loose eggs, pork floss, etc.. 5, vegetables: celery, rape, carrots, radish tassels, sesame seeds, parsley, potherb mustard, black fungus, mushrooms and so on. 6, fruits and dried fruits: lemon, loquat, apple, black dates, dried apricots, orange cake, dried peaches, almonds, hawthorn, raisins, walnuts, watermelon seeds, pumpkin seeds, dried mulberries, peanuts, lotus seeds and so on.
