Prevention and treatment of common diseases in the elderly and their diet: calcium supplementation strategies, dietary principles for specific diseases, and physical therapy for frozen shoulder.

Elderly men experience a decline in various physiological functions, leading to reduced calcium absorption. If they don't supplement their diet with calcium, a negative calcium balance can occur, potentially resulting in bone decalcification and osteoporosis. Therefore, elderly men should include plenty of calcium-rich foods in their diet. Foods high in calcium and easily absorbed include dairy products, dried shrimp, eggs, pork bones, soybeans and soy products. Additionally, green vegetables such as cabbage, celery, rapeseed, and garlic sprouts are also good sources of calcium.

Acidic foods aid calcium absorption; therefore, adding acidic seasonings to dishes is beneficial, such as adding vinegar to bone broth. Men with arteriosclerosis, hypertension, cerebrovascular disease, or coronary heart disease should minimize their intake of animal organs, brains, and bone marrow, and increase their consumption of foods lower in cholesterol. Limit high-sugar foods. Strictly limit salt intake. Men who frequently experience constipation should eat more fruits, vegetables, whole grains, honey, tomatoes, and bananas. Avoid spicy and stimulating foods.

Men suffering from chronic bronchitis and asthma should: 1. Strictly avoid excessively cold, hot, or highly stimulating foods. 2. Limit or avoid fatty meats, fish, and shrimp. 3. Increase their intake of foods that help clear phlegm, relieve asthma, stop coughing, and moisturize the lungs, such as black fungus, peanuts, lotus seeds, honey, and citrus fruits. 4. Eat plenty of green vegetables and fruits, which are rich in vitamin C. In addition, they should consume more high-quality protein, such as soybeans, tofu, milk, soy milk, eggs, and lean meat.

"Fifty-year-old shoulder" is actually periarthritis of the shoulder, a disease caused by chronic degenerative changes in the shoulder joint capsule and surrounding soft tissues. Its main characteristics are: early stage is primarily shoulder pain, while later stage is primarily shoulder joint dysfunction. The pain is milder during the day and more severe at night. After developing the condition, even eating, writing, dressing, stretching sleeves, washing the face and hair become difficult. "Fifty-year-old shoulder" is often related to a long-term lack of exercise. Due to insufficient exercise, local blood circulation is poor, making the bursa of the shoulder joint and surrounding tendons prone to inflammation.

Shoulder strain caused by exposure to cold or wind, or excessive fatigue of soft tissues, can lead to atrophy of tendons and adhesions of ligaments and joint capsules around the shoulder joint. Later, functional impairment may occur. Strengthening physical exercise is essential to promote functional recovery. Exercises that significantly impact the shoulder joint and upper limb muscles, such as swimming, rowing, gymnastics, and Tai Chi, are recommended. You can also create your own simple gymnastic exercises focusing on joint movement, such as arm circles, double-arm cloud hands, and the "wild goose spreading its wings" exercise. The range of motion and intensity of exercise must gradually increase.
