It’s Only Natural . . Gluten-Free is the name of a new Portland area business that plans to serve the expanding market for gluten-free food. I talked last week with one of the organizers, Andrew Pettingill. Pettingill said that as a first step, It’s Only Natural plans to start selling prepared glutten-free meals, and then move on to opening a market/restaurant/juice bar in the city. They are already scouting locations in Portland for the market.
