Scott Keatley, RD, contributes to the article by highlighting the benefits of popcorn for people with diabetes, emphasizing its low glycemic index (GI) and high fiber content. He recommends air-popped popcorn with minimal additives and suggests enhancing its flavor with low-GI seasonings such as cinnamon, nutritional yeast, paprika, cumin, curry, garlic powder, or dried herbs. Keatley stresses that while popcorn can be a good snack option, portion control and choosing the right type of popcorn are crucial for managing diabetes effectively.
