You’re seated at your favorite organic Mexican restaurant and spot a wonderfully fragrant bowl of organic salsa on the table. Yummy!

But don’t be too quick to dip your chips, cautions gastroenterologist Cynthia Yoshida, MD, in a recent issue of Good Housekeeping. The salsa may have been left out for several hours, warns the director of the University of Virginia Health System’s GI clinic and author of No More Digestive Problems : A Leading Gastroenterologist Provides the Answers Every Woman Needs—Real Solutions to Stop the Pain and Achieve Lasting Digestive Health.

Ask your waiter for a fresh bowl, and make sure it’s properly cold—straight from the refrigerator—when it arrives at your table. You’ll avoid diarrhea and a possible bout of food poisoning.
