After a ligament injury, there often is bleeding at the site of the injury, which can lead to swelling, pain, and other issues. From a Western medicine perspective, there are no special dietary requirements; generally, one can follow their usual diet prior to the injury. However, if you had a preference for very salty or spicy foods before the injury, it is recommended to avoid overly spicy and salty foods afterwards. It may be beneficial to eat foods rich in vitamin C and high-quality proteins to potentially aid in wound healing.
