I’m in the Dominican Republic now and went to a grocery store in Sosua (on the north shore, near Puerto Plata) looking for some healthy snacks. I found the usual tortilla chips and salty nuts but I was surprised to find some items that weren’t expected.

I found these casabi crackers. From the package: They are the bread prepared with the yucca plant by the Taino Indians when Christofer Columbus arrived at La Hispaniola in 1492. Casabi is 100% natural, organic, with a high content of fiber and enzymes. It is also gluten-free and low in calories. Because of its nutritional benefits, it still forms part of the Dominican culture. They were available in onion or cinnamon flavor, I bought the cinnamon. They are crunchy and tasty. 5 crackers has only 25 calories.
I also found some rice cakes made in Spain. There is more and more available for the gluten intolerant traveller.
