You could do a three hour lecture on this topic but it all depends on the type of damage you're talking about.
For simplicity, Proteins are the primary building blocks of your body, they are made from chains of amino acids, but again this is a VERY simplified answer.

Not all "worn out" and "damaged parts can be repaired. But the building blocks to do so, if it is possible, come from good diet. What helps you grow can help you re-grow so protein, fats, minerals, vitamins, carbohydrate and water that you intake every day. Good rest helps greatly as does a positive frame of mind (poor mental health has been shown to increase recovery times from illness).
