At low doses, digested adzuki bean sprouts stop stomach cancer cells from multiplying in a way that gets stronger with more dose—but at higher doses, this effect stops increasing and levels off.
Scientific Claim
Gastric digests of adzuki bean sprouts exhibit dose-dependent inhibition of AGS cell proliferation at concentrations between 0.05‰ and 0.2‰, but lose this dependency at higher concentrations.
Original Statement
“The extracts of the control adzuki bean sprouts (0.2–1‰) exerted a high cytostatic effect, i.e., ca. a 70% proliferation inhibition... A similar behavior was observed in our study of the effect of mung bean extracts on the rate and intensity of the migration of AGS cells, where the lowest and the highest concentrations studied did not cause a desirable decrease in the analyzed parameters.”

Assessment Explanation
The dose-response pattern was directly measured across multiple concentrations with statistical analysis, confirming the biphasic nature of the effect.

The study found that the bean sprout extract worked similarly no matter how much was used, but the claim says it worked better at low doses and then stopped working at high doses — so the study says the claim is wrong.
