Join Cameron English and Dr. Chuck Dinerstein on Episode 132 of the Science Dispatch podcast as they answer some listener questions.

Can protein supplements be part of a balanced diet, or are you better off eating proteins from whole foods? Presumably bored of soda and energy drinks, some teens are using caffeine pouches to get an energy boost. Are they putting their health at risk, or is this a media-fueled health scare?
