When stomach cancer cells are treated with digested sprouts that have good bacteria in them, a protein called vinculin increases—this means the cells’ internal structure is changing, which is linked to them stopping growth or dying.

The study found that when stomach cancer cells are exposed to digested sprouts with good bacteria, they make more vinculin—a protein that helps cells hold their shape—and this is linked to the cells stopping growth and dying, just like the claim says.
