We all heard the myth while growing up: Carrots are good for your eyesight. Or maybe even: Carrots can make you see in the dark. But where did this myth come from? And is there any basis in science? It turns out that carrots are chock-full of vitamin A, which is necessary for vision. But most people today get enough vitamin A in their normal diet, and eating an excess of the orange vegetable won’t boost your eyesight or grant you night vision. In fact, consuming more vitamin A than your body can handle (via supplements instead of natural fruits and vegetables) can be detrimental to your health. The origins of this common myth actually lie in World War II. During the Blitz (the German Luftwaffe’s bombing campaign against London and other British cities), the British government had several important reasons to persuade both its citizens and the wider world that eating carrots improved eyesight. The Ministry of Information and Ministry of Food worked together to spread some shockingly impactful carrot-based propaganda. And the myth remains prevalent to this day. Vox producer Nate Krieger spoke to an ophthalmologist and a World War II propaganda historian to get to the bottom of the carrot vision myth. This video explores the impetus behind this strangely targeted propaganda campaign, explains why it was so successful, and reintroduces the world to Dr. Carrot.
