"Facts" change

Alex Polikowsky brought a book reference:

The Half-Life of Facts: Why Everything We Know Has an Expiration Date (that links to the Kindle edition; if you want a paperback, change the page)
Facts change all the time. Smoking has gone from doctor recommended to deadly. We used to think the Earth was the center of the universe and that the brontosaurus was a real dinosaur. In short, what we know about the world is constantly changing.

Samuel Arbesman shows us how knowledge in most fields evolves systematically and predictably, and how this evolution unfolds in a fascinating way that can have a powerful impact on our lives.

He takes us through a wide variety of fields, including those that change quickly, over the course of a few years, or over the span of centuries.

Now I do not know if I agree that facts change all the time. Not all facts I mean. But his example here about smoking makes me think about the gluten, add, sugar is evil and other fads!

7 foods that were supposed to be incredibly unhealthy — but are actually anything but
We were warned by experts to avoid these edibles at all costs. Turns out the experts were wrong

Funny or Die, July 2017:

Note from Sandra:
For years I've used the examples of hamburger and pizza—every element of both of those, down to salt and oil, has been villified as "the worst part" at one time or another in my lifetime. I don't know that I've heard anything bad about mustard or pickles, but I have about tomato, iceberg lettuce, buns, beef, cheese, ketchup... And then later each was redeemed or praised as the best part.

Pizzas, same. When the food pyramid came out, breads and carbs were to be the basic foundation of diet. OH NO, says 2012: Gluten will KILL you. Cheese will KILL you.

Well it can't kill us all at once.

I think that in the absence of a truly for-real lactose intolerance or the rare actual gluten intolerance, people should eat the whole burger, or not; eat the whole pizza, or not. Stop trying to create the fountain of youth out of deprivation.
