I have. There's two things that come to mind, as areas that I've done a full 180 on. One is vaccination, and the other is nutrition.
Vaccination...I distinctly remember, years ago, thinking to myself how evil those parents were, that chose to NOT vaccinate their children (and thus, supposedly, risked harm to other children).
I don't even know what prompted this thought - I suspect that it was a rabidly pro-vaccine article in mainstream media, likely bought and paid for by the pharma industry. I had never even KNOWN anyone who was unvaccinated, or didn't vaccinate their kids. Or at least, anyone who talked openly about it.
I actually had a yearly recurring calendar appointment, for the whole family to get a flu shot every fall. I thought all these shots were GOOD for us. Big regrets there.
I'm sure you all can guess what caused me to change my mind on that one, of course it was covid. In the area where I used to live, not being vaccinated was tantamount to being an untouchable. I remember planning a group hike with some people, only about half of whom I knew. I was told that it might be a good idea to keep quiet about not being vaccinated. The hike didn't actually happen (all social activity plummeted and hasn't recovered) but I certainly wouldn't have felt welcome if it had.
Covid, and the intense, constant pressure to get a shots made me skeptical. Being skeptical made me do some poking around, and luckily I found a reddit subforum called something like CovidSkeptics (which, of course, ended up being shut down). That opened the door to lots of other information that I gulped down like a person dying of thirst drinking a glass of water.
Nutrition is the other issue I've done a 180 on. This is what I used to think:
- Fruits and vegetables are good. The more, the better.
- Whole grains are good
- Fiber is good.
- Low fat is good, if you need some fat you should use canola oil
- All animal products, and particularly meat, should be strictly limited, and used more as a condiment
I've completely switched my diet now, to carnivore/animal-based. Basically I eat lots of high fat beef - I never get tired of it - and also eggs, some dairy, fish, and poultry.
What caused this drastic change? Most people who go carnivore are trying to lose weight, or have some kind of autoimmune disease, or digestive issues. I didn't have any of those issues, but I was not satisfied with my health. As much as I tried to eat healthy, and eat all the "superfoods" that I could, I didn't feel that great.
So I was open to new ideas. And really, I have Saifedean Ammous to thank for introducing me to the carnivore diet, as well as to bitcoin. Because of my respect for him based on his book The Bitcoin Standard, I was open the idea of carnivore. He mentions it occasionally on his podcast, and also interviews lots of people that have alternative ideas about nutrition. The guest that influenced me the most was Nina Teicholtz. Her book, The Big Fat Surprise, was a revelation, and within a month of reading that, I had become carnivore.
So, those are my stories about how I changed my mind on a few big topics. How about you?
