    Why is everyone saying they would want to eat the carrots? Just because it's not good for you doesn't mean that it isn't good for your taste buds! I mean, carrots are good, but French fries!

    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.

    • ghostbirdofprey

      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.

    Carrots are just too unpredictable. You never know if you're going to get something sweet and delicious or if you're going to get something nasty and bitter. Usually, you just end up with pure blandness.

    • ghostbirdofprey

      This is why nobody eats the carrots and celery that come with their chicken wings.
      The bland ass produce that comes on the Sysco truck is a crime against agriculture.

    Than fry the carrots. Julienne cut them, than fry with your choice of oil. On a separate cup prepare some yogurt sauce by whipping some yogurt, 2-3 cloves of grated garlic, olive oil and salt. pour over your fried carrots. Bon appetite. Much tastier than french fries, and still carrots. (you can do the same with eggplants, zucchinis, whatever vegetable you see fit)

  • dweezel theyounger

    Ah yes! It makes perfect sense! Our brains "evolve" toward what we really need and what furthers our evolution and will ensure our existence! That's why we love junk food, and pot, and heroin, and alcohol, and....wait, that doesn't make sense. Evolution favors our destruction? What a silly video indeed!

    The truth is there are no scientific explanations as to why we love junk food other than a cheeseburger tastes way better than a carrot. FAT TASTES GOOD! It tastes good not because our brains know we need carbs, but because fat induces different responses chemically on the tongue and in our systems than other foods. We're also induce chemically by processed food manufactures to love their foods artificially. No big mystery here, and it has nothing to do with evolution at all. We get videos like this when we try to fit real life into fantasy.

    • Morty Smith
      Morty Smith Year ago

      Our brains did evolve to favour fats and sugars, and that is why they induce different chemical reactions, as you said. This is because that during evolutionary times, ancient humans were pretty unlikely to find such an energy-dense food as donuts just sitting there in the wild. Therefore, our brains evolved to love and crave this fatty taste, because it was so rare and energy-rich. But now here we are, kings of the earth as Hank put it, with all the carbs that we could possibly need one McDonalds away. So of course we are going to crave these foods which cause diabetes and obesity, because our brains simply have not had time to adapt to this new carbohydrate-filled, fatty diet in the past 50 years or so it has existed.
      However, in the case of drugs such as alcohol and heroin, they induce pleasure in a way that is very different to junk food, by directly altering dopamine levels in the brain at the synaptic level.

      +Daniel Broderick They weren't Are you sure about that? Humans have cultivated the opium poppy and used the resin from its flowers as a medicinal and recreational drug since at least the time of the ancient Sumerians 5500 years ago in what is today known as Iraq. Pot is similar - with a long history, and alcohol goes back even further than that. Junk food? Well maybe. It's only been around since the 40's if you consider McD's to be the first appearance.

  • Albannie Parris

    You know how we get urges for certain foods? Do you think that would be caused by lack of minerals contained in the certain food ? And if so, how would that account for the fact that we don't like some foods at all? Do we have enough of it in our bodies that we don't need the minerals and therefore our body rejects the thought of that food or is it just the design of our taste buds?

    Sadly Ironically generally speaking it is usually the stuff that is bad for you that tastes better and more of the opposite for the stuff that is good for you maybe there is some middle ground though I mean Vegan and Soy foods I am sure can produce pretty good healthy stuff as well as protein maybe with smaller calories of fat.
