Cooked carrots are disgusting and one of the only fruits or vegetables I actively avoid. The texture to me is the main problem. I hate mushy savory food.
The nutrition angle is a lie as well. There are tons of other great sources of Beta-Keratin available, like Sweet Potatoes, Kale/Spinach any dark leafy green, Romaine, Cantaloupe, Butternut Squash, Apricots, Broccoli and Colored Bell peppers. All of which are far superior ingredients than carrots in my opinion.
I don't mind raw carrots though, or even vinegar/acid "cooked" carrots like in cole slaw. But cooked carrots can F right off, and there are tons of great alternatives.
