Carrots vs. French Fries is not a fair comparison, as the latter is a prepared food. What about carrots vs. potatoes?

The brain demands fat foods because it loves it, the rest of the body screams in pain with every bite. Not literally, though.

I love carrots....

Author Jazzy ( ago)
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.

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.

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)

On the vaery first question, both

Author dweezel theyounger ( ago)
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.

How does the body know to induce the feeling that you can't breathe when you're running out of oxygen?

Author Albannie Parris ( ago)
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?

Yes, yes, junk food is actually good for you, among the most essential in fact. Just that too much of anything will kill you. Unless you're talking about artificial junk food ingredients that were designed to only replicate the pleasure effect.

Amazing how you have the nerve or the guts whichever one you want to admit to thinking that your ancestor was a monkey! I find that fascinating, I really don't know how you get up in the morning knowing that all you are or should I say thinking that all you are, is an Ape. How sad.

Is it weird that when I go to the shop with some money I will always by a carrot?

Author matthew mann ( ago)
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.
