National Geographic recently featured research by Jennifer Mathews, Ph.D., professor of anthropology at Trinity University, on chewing gum and its effect on the brain. The story explores research suggesting that gum chewing can modestly boost alertness, focus, and stress regulation, even though it provides no nutritional value, and scientists still do not fully understand why it works.
Drawing on Mathews’ scholarship, the article traces chewing gum’s evolution from ancient Mesoamerican traditions to a modern product historically marketed as a calming and cognitive aid, highlighting how cultural beliefs about gum persist alongside ongoing scientific inquiry.
