Anandamide is the molecule of pleasure, which the brain naturally produces
https://en.wikipedia.org/wiki/Anandamide
I find a lot of the information on this article fascinating for several reasons:
- It's in high concentration in cacao (chocolate, in its raw form) and, of course, cannabis
- The study that involved piglets and obesity reminded me of Horace the poet. This portion basically says that fats are necessary to form this chemical, which makes sense, since Omega 3 and Omega 6 fats are known to keep the brain healthy, the neurons well-connected, and therefore contributes to a healthy and happy brain.
- Epicurus said that pleasure starts in the belly and, lo and behold, the article says that "bile acids – which are mainly involved in the adsorption of lipids in the small intestine – modulate its biogenesis" ... in other words, the pleasure molecule is born in the small intestine.
