The problem there is confounding factors. Microplastic exposure is largely based on geography and socioeconomic class, which are both heavily correlated with health outcomes and have been since before microplastics.

That's what I meant with being controlled for similar lifestyles. If factors like wealth, education, BMI, drug use, medical history and so on are held constant, and microplastics amount in blood scales with some type of disease, it could point us in the right direction, no? Without having to necessarily study populations without microplastics exposure.
