White Yellow Tongue
The tongue becomes white or yellow during fasting. This occurrence is almost universal to all faster past the 3 day mark and often starts on day one. Some have stated that this discoloration is due to the excretion toxins which is presently unproven. The research suggest that the discoloration is an anaerobic bacterial build up due to increased protein and sulfur compounds in the tongue.
The main food of anaerobic bacteria is protein which may mean that when the tongue discolors due to fasting there is an excess protein being expelled from the tongue more than what you get from eating Big Macs and steak and eggs.
The upper surface of the tongue is covered in papillae and taste buds. Below the papillae are the mucous membranes (or mucosae; singular mucosa) which are involved in absorption and secretion.
So now comes to the big question. What are the mucous membranes secreting during a fast that increase anaerobic bacterial activity.
A team of Chinese researchers who were studying the coating on the tongue, found 13 proteins closely related to tongue coating, among which cystatin B, cytokeratin 13 and GAL7 protein were found for first time, which were closely related to the changes of tongue coating. Furthermore, there were 5 new proteins identified, which have not been recorded in the international Protein Data Bank till today, of which the biological effect needs to be further explored.
This research was not done on fasting subjects but it is clear that the tongue is normally secreting 13 proteins and the fasting state may possibly increase the secretion of these proteins.
The tongue is considered an organ off elimination by many raw food groups, herbalists and other holistic health practitioners. They consider that during a detoxification the body uses every avenue possible to rid itself of toxins including the tongue and the logic is back by common experience, such as a white tongue during periods of illness.
My question that I cannot find an answer for is what is being eliminated.
Candida is white and has been found on the tongue. When Candida albicans thrives on the tongue, this is called oral “thrush.” One person stated, “My gut problems and white tongue were exacerbated AFTER starting the “anti candida” diet.” This implies that killing Candida causes the tongue to become white. The fasting state especially water fasting decreases blood sugar and immune system activity. A white tongue during fast could be in-relation to candida death.
Solutions For a Coated Tongue
One of the problems caused by an increase in mouth bacteria is cankers. There for during fasting is it is very important to brush your tongue use dental floss or a water pic and a mouth was a few times per day to prevent cankers.
