False 2/10
“The human gut microbiome produces enough neurotransmitters to directly influence human personality traits and temperament.”
The evidence does not support a direct microbiome-to-personality effect through microbial neurotransmitters. Gut microbes do make neuroactive chemicals, but these generally do not cross into the brain in amounts that would directly shape personality or temperament. Current human research mainly suggests indirect gut-brain signaling and possible links to mood or symptoms, not proven direct control of stable personality traits.

“Parasitic infections are a common cause of sugar cravings in otherwise healthy adults.”
This claim is not supported by credible evidence. No peer-reviewed studies link parasitic infections to sugar cravings in healthy adults. The CDC does not list sugar cravings as a parasitic symptom, and a PubMed search returns zero direct evidence for this connection. The only sources asserting this link are low-credibility wellness blogs and holistic clinic websites citing no clinical research. Well-established causes of sugar cravings include stress, sleep deprivation, hormonal fluctuations, and dietary patterns.
