Thats what I was talking about with the tryptophan depletion. It you look at the results of those studies too, they do not paint any clear pictures.
You can experiementally cause tryptophan depletion for instance, by giving people a drink high in other amino acids. This doesn't consistently cause depression in normal controlls. Sometimes it does, sometimes it doesn't.
The only semi-consistent results are that tryphophan depletion precipitates depression in those treated with SSRI's, but not in unmedicated depressed people, depressed people treated with NRI's, or normal controlls.
