A local doctor is giving a free nutritional talk today in Kalona. Chris Grier of Bright Futures Chiropractic says real food can be more beneficial than processed food, but he says it’s not always so easy to tell which is which. Dr. Grier says one of the most common things people can do to improve their nutrition on their own is to ask themselves whether or not a food will make them healthier before eating it. The free talk is tonight at the Kalona Public Library at 6:45.
