Jamba Juice Plain Oatmeal with Brown Sugar (12 ounces) contains 220 calories, 3.5 g total fat, 1 g saturated fat, 20 mg sodium, 5 fiber, 8 g protein. The oatmeal serving is on the larger size (unless you order the medium or large at Au Bon Pain) compared to the others. Interestingly, the oatmeal is made with steel-cut oats and is the only one I found to be slow-cooked.
The Fresh Banana Oatmeal is the flavor that adds the least amount of extra calories (12 ounces, 280 calories, 4 g total fat, 1 g saturated fat, 20 mg sodium, 6 g fiber, 9 g protein). Apple Cinnamon, Berry Cherry Pecan and Blueberry & Blackberry bump the calorie total to 290, 340 and 290, respectively—and increase sodium by a little bit in each.
