Experient Health: “Snacking on soft drinks, candy bars and chips several times a week can detract from an overall healthy diet and lead to weight gain. Plus, many of the typical vending machine choices offer little nutritional value or substance, and could leave the employee hungry again soon after – leading to more unhealthy eating. This can drastically affect your health care costs, as obesity is a catalyst for many other illnesses such as high blood pressure, diabetes and heart disease. Even employees who are health-conscious often forget to bring healthy snacks to work, leaving the vending machine as the only option.”
“You can help employees choose healthier snacks at work by controlling what is offered in the vending machine. Request that your vending machine company stock machines with healthier alternatives (you could also look into switching to a vendor who provides healthier options). If your vending machine will still include unhealthier snacks, help employees identify which items are good for them by marking them with colored stickers or asking the vending machine company to place them on the same shelves.”
