  • Fries are a package of carbs and fat, so they’re a jackpot food.

  • Donuts. Both fat and carbohydrates, and sugar, and artificial flavorings and artificial coloring. And the always fantastic preservatives.

  • I once wondered about why we crave the foods that are bad for us and realized that in a survival situation you would live longer on meat, fat and salt because you need the salt, protien and energy, but never realized it was due partly to brain size as well.

  • the fries are prepared, the carrots are not. I would much rather eat roasted carrots with seasonings than fries. don't get me wrong, I love fries, I'd choose them over the raw carrot any day. but it's not quite a fair fight to pit a food that's already cooked and ready to eat against raw food that doesn't even look washed yet.

    JazzyJazzyVor 3 years
    • Meanwhile, I think that plate of fries looks old and soggy, whereas the carrots do not. besides, raw carrot is fine, raw potato, not so much.
