When stomach cancer cells are exposed to high doses of digested adzuki bean sprouts, their nuclei change shape to become round or oval—this is a known sign that the cells are starting to die.
Scientific Claim
Gastric digests of adzuki bean sprouts induce apoptotic nuclear morphology in AGS cells, characterized by uniformly round or oval nuclei, at concentrations of 0.5‰ and higher.
Original Statement
“After Hoechst 33342 staining, the cell nuclei of the AGS cells treated with the high concentrations of the extracts were uniformly round or oval. Such nuclear morphological changes in AGS cells were also recorded by Zou and Chang after the application of a black soybean extract.”

Appropriate Language Strength
definitive
Can make definitive causal claims
Assessment Explanation
The observation of nuclear morphology is a direct, visual, and reproducible finding under controlled microscopy conditions, supporting definitive description.
Evidence from Studies
Supporting (1)
The study found that chemicals from adzuki bean sprouts can kill stomach cancer cells and make their nuclei look like they’re dying—which matches the claim, even if the exact shape wasn’t measured at every dose.
