Looks like the picky eater issue runs a bit deeper for you if you take such offense. I am a picky eater who has taken to eating many newer foods the past 5 years. It truly is as trivial as just doing it. You may gag at some stuff but as with everything in life, if you don't even try to push through it then what can you expect.

There was no basis provided. I didn't judge anyone and have tried many diet changes over the years in my quest to better understand food, nutrition and health. I didn't tell anyone to do anything but made the simple suggestion that plant based has made marked improvements in areas for me and that there are no downsides to increasing plants in diet.

Did I ever try to tell you what you should like? Nope. Get a grip.

I don't think he told you anything. He wrote something and you read it.

There's also mentions of "slow shifts" and similar, indicating that the change of your diet is not radical and sudden, but gradual and slow.

Picky eaters have a somewhat disease and should try to incorporate variety. Otherwise you risk black swans by eating practically the same thing all your life. Eating many ingredients is antifragile :D
