Sugar
Reducing sugar can have a significant impact on your health because eating foods high in sugar is linked to increased fibromyalgia pain. Sugar is a well-known ingredient in candy and soft drinks but is also in foods considered being healthy—such as yogurt. When checking nutrition labels, it is helpful to know that glucose, fructose, and sucrose are other names for sugar.
Carbohydrates
Refined carbohydrates such as cookies, many breads, pastries, and white rice are digested quickly, causing blood sugar levels to spike. The effect does not last, however, and blood sugar soon drops, making the individual hungry again. These fluctuations can make the fatigue and pain of fibromyalgia worse and contribute to overeating.
