“About 35% of microplastics in the ocean originate from synthetic textiles.”
The 35% figure is real, but it is commonly tied to a narrower statistic: the share of primary microplastics released to the ocean from washing synthetic textiles. That does not justify saying 35% of all microplastics in the ocean originate from textiles. Credible sources also report wider ranges and lower estimates, so the unqualified claim overstates both scope and certainty.
“Researchers estimate that the average person ingests about 5 grams of plastic per week, which is approximately the weight of a credit card.”
The evidence does not show that the average person ingests about 5 grams of plastic per week. The original research estimated a wide range, with 5 grams as an upper-end figure, not the average, and later reviews indicate typical estimates are lower. The “credit card a week” line is a simplified advocacy/media framing that overstates the current scientific picture.
“Humans ingest an estimated 250 grams (about 8.8 ounces) of microplastics per person per year.”
The 250 g/year figure is not supported as a reliable current estimate. It comes from older, assumption-heavy upper-bound modeling that later reviews and WHO-linked literature say likely overstates exposure. More recent assessments report no consensus for 250 g and generally indicate much lower annual intake, often in the tens of grams rather than hundreds.
“Lactic acid bacteria present in kimchi can bind to intestinal microplastics and facilitate their excretion from the human body.”
The underlying science is real but overstated. A 2026 peer-reviewed study showed a kimchi-derived bacterium (Leuconostoc mesenteroides CBA3656) can adsorb polystyrene nanoplastics and increase their fecal excretion — in germ-free mice. No human clinical trials have confirmed this effect. The claim's reference to "the human body" implies proven human efficacy that does not yet exist. Additionally, only specific LAB strains were tested against specific plastic types, not the diverse microplastics humans actually encounter.
