The following is a list of foods and that wreck havoc on the fibromyalgia patient:
Aspartame: Better known as NutraSweet. One study published in Annals of Pharmacotherapy in 2001 showed that eliminating aspartame from the diet of fibromyalgia patients resulted in improved symptoms. Aspartame is an excitotoxin, which his known to stimulate pain receptors.
BHA and BHT: These preservatives are often added to a wide variety of foods. Both are known to form potentially cancer-causing reactive compounds in the body. Other side effects include immune disorders, liver and kidney damage, infertility, and elevated cholesterol.
Monosodium Glutamate: This additive and flavor enhancer is found in a number of processed and frozen foods. Like aspartame, it is an excitotoxin had has the same ability to stimulate NMDA receptors. MSG often hides in foods under names such as: glutamate, sodium caseinate, hydrolyzed vegetable protein, texturized protein, natural flavoring, yeast extract, among others. Glutamate in muscles may contribute to pain sensitivity.
Nitrates: Used primarily in processed meats like bologna, bacon, and deli meats, nitrates have been shown to cause fibromyalgia patients issues such as: difficulty breathing, dizziness, headaches, nausea, and vomiting. Patients also experienced intensified symptoms of pain when ingesting this preservative.
Phosphates/Phosphoric Acid: This preservative prevents chemical changes of food that influence texture, flavor, color, and appearance. They also attract trace minerals from your body which can result in dietary deficiencies. Anything that promotes nutritional deficiency in people who have fibromyalgia should be avoided.
