Do you feel sleepy after potatoes?
Potatoes are rich in starch, which raises serotonin, causing sleepiness, fatigue and brain fog. But now we may have another mechanism at play?
The concentration of the benzodiazepines (BZ) found in potato was extremely low, however, their biosynthesis most probably takes place in the plant tissue.
The availability of BZs in plant nutritive points to a possible source for the previously reported presence of BZ in brain and peripheral tissues of several animal species and man.
