chronic fatigue syndrome definition

Chronic fatigue syndrome is a condition of intense, long-term lethargy and tiredness that is not assuaged by sleep, relaxation or rest.  It is often associated with autoimmune diseases and may be a sign of vitamin deficiency, such as iron or vitamin D.  Eating probiotic foods such as homemade fermented sauerkraut, yogurt and kefir can have a large impact of those suffering from chronic fatigue syndrome because the good bacteria in these foods fight bad bacteria, boost the immune system and result in higher energy levels.
