Abstract:

Abnormalities of Essential Fatty Acid (EFA) incorporation into phospholipid are found in chronic diseases. More recently changes in circulating EFA metabolites (EFAM) together with EFAM hypo-responsiveness of immune cells and EFAM production from cells have been found associated with disease.

We hypothesize that changes in ratio of EFAMs are the normal physiological responses to stressors, but when stressors are excessive or prolonged, EFAM systems may become unpredictably hypo-responsive owing to factors such as receptor down regulation and substrate depletion. In time, many homeostatic system become deranged and held in that state by minor stressors.

Literature review of chronic fatigue syndrome (CFS) shows hyper and hypo-responsiveness in immune function, several Hypothalamo-Pituitary (HP) axes and sympathetic nervous system, all relatable to dysfunctional changes in EFA metabolism.

For the first time, we explain chronic immune system activation and hypo-responsive immune function in CFS; through EFAMs. Dietary EFA modulation (DEFA) can alter ratios of both membrane EFAs and produced EFAMs, and if maintained can restore hypo-responsive function.

We discuss dietary strategies and relevance in CFS, and a case series of CFS patients applying DEFA with other titrated published managements which saw 90% gaining improvement within 3 months and more than 2/3 fit for full time duties. This hypothesis and DEFA may have relevance in other chronic conditions.

Abstract:

This report is a review of the unproven diet therapies recommended for individuals with chronic fatigue syndrome (CFS). Diet therapies promoted for the relief of CFS symptoms by the authors of five CSF self-help books were evaluated on the basis of nutritional adequacy and scientific rationale.

Unproven diet therapies for patients with CFS include megavitamin/mineral supplements; royal jelly and other dietary supplements; and elimination, avoidance, and rotation diets. Claims that these therapies relieve CFS symptoms and promote recovery are anecdotal and have not been substantiated by clinical research.

The yeast-avoidance and sugar-free diets, both promoted to combat Candida albicans overgrowth, are of questionable value in treating patients with CFS. The rotation diet is not balanced and does not meet the current recommended dietary intake levels. Diet strategies that call for the avoidance of food additives, preservatives, sweeteners, and other ingredients are not supported by available evidence and are not practical for patients with CFS.

A diet plan for patients with CFS should be based on sound nutritional principles and common sense. Until the results of studies demonstrating the benefits of particular diet therapies in the management of CFS are available, patients with CFS are advised to eat a varied diet selected from among and within the basic food groups to ensure an adequate nutrient intake and to reach and maintain a reasonable body weight.
