In this episode of 'Chemistry for Your Life,' hosts Melissa and Jam explore the chemistry behind the popular belief that eating carrots improves night vision. They take a deep dive into the scientific processes, including how beta carotene from carrots is converted into vitamin A, then into rhodopsin, and how this helps with night vision. They also discuss the historical context of this belief, dating back to World War II propaganda, and expand their discussion to include other fall foods rich in beta carotene, such as pumpkins and sweet potatoes. The episode also touches on fun facts, personal anecdotes, and a special shout-out to a new community member.
