Some people dont like tue high cholesterol in eggs.
Ive seen the absolute gambit of picky eaters and food allergies.
10 years ago none of these issues were issues
The studies on cholesterol in eggs changes every 5 years. 🤣
Eggs themselves might not be what is bad but the source of the eggs with what the chicken ate might be, high stress in the chickens related to stressed eggs with certain cortisol/cortisone or whatever in the chicken, etc etc blah blah.
Celiacs is only a thing because we've fucked up the process of flour and stuff. It's not real bread foods anymore.
Other allergy developments are similar as well.
