There's a special ingredient in red grapes called resveratrol that might help keep us safe from a tummy illness called bowel cancer.
Doctors are trying to see if giving a little bit of resveratrol to people can stop tiny growths in their tummies from becoming bigger and causing problems.
This is a big study, and hopefully, it will find ways to keep people healthy and happy for a long time.
Remember, eating lots of fruits and vegetables, like red grapes, is always a good idea for our bodies!
