After a foot sprain, dietary adjustment is also very crucial. Eat more easily digestible foods with high protein content, such as soy products, milk, onions, eggs, fish and shrimp. Eat more fresh fruits and vegetables, and forbid spicy and irritating foods, because after eating spicy and irritating foods, it is easy to cause swelling and pain in the ankle area, which is not conducive to recovery. Eat less oily, sweet and indigestible food to avoid increasing the burden on the gastrointestinal tract, causing abdominal pain, bloating and constipation, and also affecting nutrient absorption. Therefore, we must pay attention to the adjustment of the diet structure, pay attention to the warmth, avoid getting cold, elevate the affected limb when resting to facilitate the venous return, and promote the early recovery of the disease through comprehensive conditioning.
