I am trying to regulate my sleep but I don't like to drink pills or supplements. I was wondering if there are certain foods that help induce sleep?
Let's see here... melatonin is synthesized like this:
Tryptophan (Trp) --> 5-HTP --> Serotonin (5-HT) --> N-Acetylserotonin (NAS) --> Melatonin
As a result, any food which contains tryptophan is a good candidate.
Foods containing Trp: Egg, Spirulina and Cod are good sources of tryptophan.
As it happens, 5-HTP is also a good candidate, since you can buy it as a dietary supplement. Keep in mind though that whether you're boosting Trp or 5-HTP, you're facing a lot of rate-limiting enzymes so there's no telling how strong the effect is really going to be.
Of course you can just take melatonin directly, since it's available as a dietary supplement. If you need anything more powerful than that, go seek your doctor.
