Dietitian’s tip: Stone-ground cornmeal — dried corn that has been ground into a grain — includes the nutritious bran and hull, making it a good source of nutrients, including fiber, vitamin C and potassium.

Dietitian’s tip: Cornmeal gives these muffins a crunchy texture that pairs well with any sweet berry, from raspberries to blueberries. If one dozen muffins is too many, freeze any extras in a lock-top plastic bag.

Dietitian’s tip: Buttermilk is made by adding special bacteria to fat-free or low-fat milk to give it more texture and a tangy taste. It may seem like buttermilk is high in fat, but in fact, most varieties aren’t.
