It seems that the sugar mess with the creation of Tryptophan in microorganisms. We are unable to synthesize it, so we don't have this methabolic path. So far, so good. We could share our Tryptophan (from chocolate, milk, red meat, fish, eggs...) with the gut microbioma, solving the problem in part but:

1) It seems that tryptophan is related with control of inflamatory processes. I understand (but I could be wrong, is not my speciality) that therefore a healthy level of Tryptophan in gut protects us from developping crohn's disease and similar problems.

2) And as Tryptophan can be used to make serotonin and melatonin, It seems that badly stressed humans had yet low levels of Tryptophan. I'm hypothesizing that this sugar could be particularly harmful to them, even if is proven safe for non stressed people.

3) Tryptophan is needed for melatonin production.

4) And, low levels of tryptophan lead to obesity. Tryptophan triggers the "stop eating" satiety message, so stressed people typically eat continuously, and gain a lot of weight.
