Jiang Shoushan (a famous doctor in nephrology) knows that I have been a medicine jar since I was a child. When I was four years old, I couldn't walk for nearly two years because of ischemic necrosis of the femoral head of my left foot. I can only lie in bed and envy my brothers and sisters going out to play. At the age of twelve, I got hyperthyroidism again and needed to take medicine for a long time. At the age of thirty-eight, the foot disease recurred and there has been no surgical treatment. Because of congenital deficiency, it is more necessary to recuperate. As a doctor, I fully understand that prevention is more important than treatment. The human body has its own recovery mechanism. As long as we can provide it with enough energy (nutrition), the body will naturally be healthy. In fact, after the foot disease recurs, I rely on the nutritional power of health food to prevent the disease from getting worse (of course, the part that died of ischemia when I was young is irreversible), so the patients in the outpatient clinic often ask me curiously what "maintenance" I have taken, and I want to share it with you here. In addition, as long as I go abroad, I will definitely go to the supermarket to buy a bottle of local yogurt when I arrive at my destination, because the strain is adapted to local conditions, and many people often feel uncomfortable when traveling, not necessarily because they eat broken things or food infected with bacteria and viruses, but because different countries have different eating habits and the distribution of human intestinal flora is different. When our original intestinal environment is affected by different external environment, intestinal flora will be affected, so intestinal problems are prone to occur. As long as you make good use of beneficial bacteria, you are not afraid of going abroad to spoil your fun.
