What food should i eat or what food should i avoid after injury? i have wounds all over my body and stitches too.

High protein diet: A high protein diet will help in healing the injuries. This may be a combination of fish, chicken and other meats; beans and you may even wish to use protein supplements. Go easy on carbohydrates and saturated fats.

Balance + protein: Eat a balanced diet and make sure you get plenty of protein to help rebuild all the damaged tissues.
