Dream-boosting foods

Tryptophan is one of the 22 standard amino acids, which is essential in the human diet, because it cannot be synthesised by the organism. This means that it must be consumed - it is not produced naturally by the body. Amino acids such as tryptophan act as building blocks for protein biosynthesis, and specifically, tryptophan functions as a biochemical precursor for compounds such as serotonin (a neurotransmitter, which is in turn converted to melatonin), niacin (Vitamin B3, in the liver) and auxin (a phytohormone). The disorder, fructose malabsorption causes improper absorption of tryptophan in the intestine and reduced levels of tryptophan in the blood, as well as depression. 
Tryptophan is a routine constituent found in most proteins, in addition to a variety of other food sources which I discuss further in this article. Where I am able to find information as to the tryptophan quantities in each particular food source, I will include this. Tryptophan is available in health food shops as a dietary supplement. Clinical studies have produced mixed results as to the effectiveness of tryptophan as a sleep aid, but it has been shown significant effectiveness in treating various conditions caused by a lack of serotonin in the brain and some promise as an antidepressant on its own, or as an augmenter for other antidepressant medications. 5-HTP (see my earlier post on 5-HTP as a lucid dream supplement) is a metabolite of tryptophan which has been suggested as a possible treatment for epilepsy and depression as it easily crosses the blood-brain barrier and is readily decarboxylated into serotonin. 

Apparently, low levels of tryptophan are linked to poor dream recall. The recommended dietary intake of tryptophan is 392mg for men and 322mg for women, assuming a normal protein intake. Some doctors prescribe 5g of  'theraputic' tryptophan without ill effect and there is no prescribed upper limit for ingestion, but in 1989 there was a scare when 1,500 incidences of permanent disability and 37 cases of death caused by the neurological disorder, eosinophilia-myalgia syndrome (EMS), which was traced to a contaminated batch of L-tryptophan, supplied by Japanese manufacturer, Showa Denko KK. The contamination was believed to be the result of genetically-engineered bacteria, leading to GM-protesters claiming it was the production technique which was responsible for the outbreak.


Vitamin B6 is also a great dietary supplement (see my earlier post on Vitamin B6 as a lucid dream supplement) because it converts tryptophan into serotonin and niacin, contributing to a regulation of sleep patterns, appetite and mood It is also essential for proper maintenance of red blood cell metabolism and has important functions for the immune and nervous systems, as well as lowering the risk of cardiac problems, depression and some skin disorders. Double-blind studies have shown that a daily intake of 250mg of Vitamin B6 (also known as pyridoxine, pyridoxal or pyridoxamine) can significantly increase dream content, including vividness, bizarreness, emotion and colour perception. This amount is in excess of the daily recommended intake for adults, which is 100mg. Many people will receive their full daily amount from diet alone and the study referred to above was only carried out for a period of 3 days, although casual dream experimenters may require adjustment to the amount or period of supplementary Vitamin B6 to get a noticeable effect.

There are many other food sources which are rich in dream-inducing nutrients, such as tryptophan, melatonin and Vitamin B6, but those included above are generally stated as containing the highest levels. In order to fully attain the highest quality of these nutrients, it is essential that food should be at its freshest and prepared cleanly (without extra additives and not overcooked). I will upload some further articles on dream nutrition and supplements and maybe some of my own dream-boosting recipe ideas.
