You Ache What You Eat
It is important to remember that only the one who eats is the one who will know whether a given diet improves chronic pain.
There is some hard science available for those seeking help in what they eat: foods that may help control chronic pain in conditions such as fibromyalgia and rheumatoid arthritis include soy, cherries, peaches, oranges, cranberries, kiwi, asparagus, and cauliflower.
In the case of an inflammatory illness such as rheumatoid arthritis, dairy products, chocolate, eggs, meat, wheat, corn, and nuts can actually worsen inflammation and should probably be avoided, at least in large doses.
If a patient is overweight, losing weight can have many beneficial health effects, including improvement of cardiovascular health, pain due to arthritis, fatigue, and blood glucose levels, and lowering of incidence of type 2 diabetes.
Eating a diet that is low in sodium can help lower blood pressure and improve cardiovascular health.
