More on tryptophan and serotonin production
Here is a really good article about Tryptophan that touches on Sleep Disorders, Carbohydrate Cravings, and Obesity. It's pushing Tryptophan as a supplement, but there are reputable references at the end, and it seems to be well-researched. I like it because it explains the very delicate balance of carbohydrates, protein and neurotransmitters in a way that I can understand. It also explains why 5-HTP causes nausea and why Tryptophan doesn't.
Low serotonin levels present as a general feeling of depression, anxiety, fatigue, lethargy, low concentration, low self-esteem, insomnia, sleeping disorders, loss of coping skills, irritability, easily stressed, insecurity, loss of apetite, sugar/carb cravings, weight gain, unexplained weight loss, impulsivity, impatience.
This article, while lacking in understanding about the carbohydrate/protein issue with tryptophan absorption, explains exactly why L-Tryptophan is banned in the US. It still comes off as a bit slanted, but less so than other articles I've come across. It also notes the correlation between the banning of tryptophan and the release of prozac, which appeals to my inclinations towards conspiracy theory. :)
This article from The World's Healthiest Foods explains a great deal about tryptophan and how it is used by the body. The article uses plain english so it's easy to understand. However, it still does not cover the necessity of carbohydrates in the absorption of tryptophan, which is a shame. Yes, it's difficult to absorb tryptophan, but it's still quite possible to get a good amount and still not fall prey to the carbohydrate/blood sugar roller coaster.
