I would rather eat the carrots, but I'm a horse so that's probably a given.

These french fries look shit, I'm going for carrot.

I, honestly, would take the carrots. I have some uncontrollable addiction to carrots for some reason and developed a reputation as 'the man rabbit' in school...yeah. I don't know why though. I think it's because the carrots are crunchy or sweet. I'm weird...

I think I'm addicted to fruit. Or some sort of citrus juice. o.o Beats being addicted to some other stuff though.

+Patty9752 I think you are blinded by the fact that vsauce has more "interesting" facts because he uses technicalities way too much. I do somewhat agree though because vsauce is very good at pulling in viewers

I'm trying ot find that sci show episode where you talked to someone about how bonds release energy in our cells, what was it called?
Report spam or abuse
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.

To Be honest.. Id eat the fries.

How the hell do you grow taller???
Report spam or abuse
Ohhh you wanna get big, bro?  You need to eat -- and you need to eat a lot.  Carbohydrates such as brown rice have an effect on growth hormones (GH). Exercise can also increase both testosterone and GH. The higher your growth hormone level is, the more likely you will grow. In addition, you will need to eat above your caloric metabolic rate. You will need to eat at least above 500 calories each day to see a difference. (your weight x 20)+500. That should work. Try to eat at least 90% of good foods every day or else you might become fat. Also remember that the bone mineral calcium is what your bones are built from, so drink an adequate amount of milk each day. Do not exceed the daily amount of calcium; it's actually dangerous. Don't be discouraged -- stay with the program. P.S. There is nothing better you can do for your body than eat eggs -- and a lot of them!!!

You should all know healthy food makes your brain proficient enough to keep as active as humanly possible as long as you're aware some important foods we need to focus on might not be tasty but it still needs as much vitamins and minerals to get involved in positive activities. As opposed to the junk food you're used to that leads to many psychological and physical problems you can possibly think of in a massive book.
Report spam or abuse
Nope. Brain only takes what it needs - Blood brain barrier. Eating greasy foods does increase blood pressure temporarily, some fatty foods will "slow you down" but overall you can be active and healthy and still have a burger. 
Report spam or abuse
+sacr3 Doesn't really matter. Eating fatty foods if it's done excessively can have long term effects in the blood pressure and for a small period of time it can make you lethargic. This is why the brain and the heart controls the fatty acids if physical activity is not a factor. Notice morbidly obese peolle bite off more than they can chew when they constantly eat as many food products that's considered a health risk, sugary drinks are also the main suspects to that cause.

Is it weird that I was eating salad while watching this and I ate a donut and potato chips while watching chefs make vegetarian food?

carrots + hummus = a delicious snack  fries + mcdonalds (because thats where they usually come from) = a sore stomach and a slightly depressed brain thats right! junk food can make people depressed its been proven

Wrap the carrots in saran wrap and put them in the microwave on the baked potato setting then cut them up with a little bit of butter and some salt (and maybe real maple syrup) and you'll never want fries again. But cooked or raw, I'll take the carrots, thanks.

These foods helps the brain as far as energy, but they also clog up your arteries, and some say they contribute to cancer or benign tumors. Yeah, there is good and bad in everything.

So that's why I crave comfort food. That's my biggest weight challenge. I find comfort in food. Actually, pizza is my comfort food of choice. That's why I run long distance.

soo if we started eating more stuffs back then as homo habilis, and we could supply our bodies with enough energy to sustain a bigger brain, and eventually our brains evolved into bigger and better...why didnt the other omnivorous animals brains (like pigs) turned bigger and better too? what other factors affected our brains evolution and why arent there other living beings with a brain like ours, capable of doing science, math, building stuffs, etc?

I wonder if my Tourette's has any impact on how much energy my brain uses.  It's like I've got constant background processes going on that I also have to use more energy to negate and it's a big mess.  It'd be interesting to see if that is any bit a contributor towards my inability to get up to a healthy weight.  Probably not, but worth thinking about I guess.

Lot of people get addicted to the "high". Altering your reality is different than the norm and can make for a lot of fun (sometimes with repercussions). Also, addictions. Some chemicals excite our brain and our brain craves the same excitement just as food may excite your brain. Drugs are an easy form of this.
