That if something is marketed with health-based language or claims, it must be true. (or that things that are healthy offset other unhealthy activities/behaviors/consumption, i.e. "I might have eaten a ton of ice cream today, but I had a lot of protein so that'll make up for it")

Way too many people buy into "healthy" products, especially the very expensive ones, without doing so much as a single search regarding if it's even necessary for them, or if that particular product is even healthy in the way it appears.

People think anything with protein is inherently healthy, and the more the better, even if their body can't use all the protein they consume, so they'll eat multiple protein bars, have meat with every meal, and drink a protein shake every day.

Someone on social media says eating all raw meat and drinking raw milk is healthy, and they don't even look up how much more likely you are to get a disease from consuming them. (not to mention the impact on their wallet)

A drink will be advertised as a "wellness shot" and is just some fruit juice with ginger, but people will pay 8 bucks for it every day assuming it'll revolutionize their health, then drink a bunch of beer later that night and wonder why they feel awful later.

Hell, people will even take multivitamins or supplement powders that have 100's of %'s of their recommended daily intake, and just assume that if they get 500% of their recommended vitamin B, they'll magically become "healthy" by doing so, instead of "only" getting 100%.
