Carpal tunnel syndrome is a painful condition caused by swelling and inflammation in the wrist and tendons of the fingers that surround the median nerve.
When the swollen tendons squeeze or compress the median nerve, it causes pain, tingling, and numbness. Carpal tunnel syndrome is sometimes referred to as a repetitive motion syndrome.
Foods and supplements that alleviate inflammation may benefit this condition. In some instances, the right type of diet may alleviate symptoms enough so that other medical treatments are not needed. In other instances, it may be a beneficial addition to medical treatment.
Certain foods may also exacerbate this condition, by furthering inflammation in the body.

Avoid foods that are high in salt, including processed, packaged foods. Also avoid adding table salt to meals.
A too-heavy intake of alcoholic beverages can raise inflammation levels in the body.
