I would show this video during my first face-to-face intro nutrition class to break the ice and to illustrate the evolving (and often confusing) science of nutrition. While they misspell "dietician" and not all "facts" are quite right - it also allows opportunity to comment on those. I'm showing it in my online only course this semester as part of a recorded Zoom course orientation and overview video - we'll see how it goes! You might have seen it, but if not you'll get a chuckle!!
