evidence: FULL CLAIM: "It’s the cat parasite [...] Once it's in the body it's called toxoplasmosis, and this parasite is so intelligent [...] they send signals to the nervous system to different parts of the impulse control to release ghrelin hormone, or hunger hormone, that starve you of glucose, so you're just craving sugar and craving sweets. This then leads to depression, highs and lows, irregular heartbeat, muscle twitching, brittle hair, dry skin, psoriasis, unregulated sleep cycles" [...] A Facebook reel shared on 6 June 2024 claimed that a so-called "cat parasite" causes toxoplasmosis. It also claimed that toxoplasmosis leads to an increased release of the ghrelin hormone (commonly known as the "hunger hormone"), which in turn leads a host of other health issues including "depression, highs and lows, irregular heartbeat, muscle twitching, brittle hair, dry skin, psoriasis, [and] unregulated sleep cycles". [...] The "cat parasite" claim has received media attention in the past, primarily addressing the potential link between T. gondii, mental illness, and risk-taking behavior. However, there is no apparent evidence for an association between toxoplasmosis and an increase in the ghrelin hormone. We explain below.
