Todd is 13 and lives in an urban apartment. He spends most of his time watching TV and eating "junk" food. One afternoon, during recess, he falls on the playground and breaks his leg. Although he appears to be healthy, his leg takes longer to heal than expected. What might be the cause of the longer healing time?
Assuming that there is no other disease process involved, Todd's problem is probably related to his poor diet. Good nutrition is important for promoting the healing process. Insufficient quantities of protein, vitamin C, vitamin A, and vitamin D would cause the normal healing process to occur at a much slower rate. Todd's inactivity may also contribute to his slower rate of healing.
