There was a health article in one of my history texts the title of which was something like, “It was all fun and games until his jaw fell off.” Until sometime in the late 1930’s it was felt that adding radium to products and food would have amazing healt benefits. (Pictured was an ad for radium enhanced toothpaste.) One of the early uber-rich was a health nut and he overdid the radium. He developed bone cancer and, apparently, one day his jaw came apart.
My mother pointed out how frequently government health data contradicted itself. This was in the early 60’s. She ticked off eggs good for you, eggs bad for you, bacon good, bacon bad, saturated fats good/bad...she kept going for a fairly long run. She was correct. Government data has been moist defecation forever.
Right now I am in the bacon good fad.
