All they present is a simple correlation so they can't say one variable causes the other. This is not a very good study. I have a feeling they looked at a bunch of variables and this one they found was statistically significant so they wrote a paper on it. I would not pay any attention to this finding unless you are researcher and can create a better study to explore this initial findings.

You have a feeling they found a significant variable? How else would you do it? Are you going to randomize people to eat or not eat green vegetables?
