**5. Palindromic rheumatism and diet**

It has been observed that certain types of food can trigger a periodic attack of Palindromic rheumatism and elimination of that type of food from the diet has resulted in a reduction of attacks. According to a clinical trial conducted for evaluation of the role that certain type of food can play in PR, patients show that patients who were offended to eat eggs, cheese, fish, and canned vegetables resulted in the complete cessation of attack, and those patients who were presented with these food show more reoccurrence of attack. Therefore, offending food should be avoided to reduce the occurrence of PR although this needs more research that which type of specific food should be avoided [4, 42].
