Neurasthenia is a neurological disorder that occurs when patients are under long-term tension and stress, and is often accompanied by emotional worries, irritability, sleep disorders, muscle tension pain and other neurological disorders. The diet of neurasthenia patients has many of the same basic principles as those of other diseases, such as balanced nutrition, reasonable matching, no overeating, etc., but also has its own special characteristics. Patients with neurasthenia mostly have decreased mental vitality and emotional disorders, so patients should try to avoid the intake of stimulating foods, such as tobacco, alcohol, coffee, tea, etc., to reduce the stimulating effect on the brain nerves and avoid aggravating the symptoms of discomfort. Patients with neurasthenia may have symptoms of gastrointestinal discomfort such as abdominal distension, indigestion and constipation. Patients should try to avoid spicy, cold, fried, greasy and other foods with digestive tract irritation to avoid aggravating the burden on the digestive tract. In addition, neurasthenia patients can appropriately supplement foods rich in vitamins, high quality protein and trace elements, such as fresh fruits and vegetables, fish, dairy products, lean meat, grains and other foods, to provide the material basis for brain metabolism and help the recovery of physiological functions. To sum up, the diet of neurasthenia patients should pay attention to balanced nutrition, easy digestion and absorption, avoid the above-mentioned stimulating foods and raw, cold, spicy and other foods, and supplement vitamin-rich, high-quality protein and trace element foods in appropriate amounts to promote physical recovery.
