From The Brains Behind Brains On, this is the moment of um.

Um, um, um, um, um, um, um, um, moment of um comes to you from APM studios. I'm Anna Weigel.

Um. Have I ever told you about my friend Troy? I love Troy. He's a geologist, which means he studies rocks.

Troy also rocks as a person. He was a bridesmaid in my wedding. He's a geologist, which means he studies rocks. Troy also rocks as a person. He was a

bridesmaid in my wedding. He has a puppy named Rosie, and he's always up to something interesting.

A few years ago, he was really, really busy with school and work and life, and he hardly had time in the day to even make himself a simple meal.

So he read about this special powder drink

that turns into a vitamin-filled shake when you add water. And he was like, perfect. Now I can just

slurp up this vitamin shake whenever I'm hungry instead of spending all that time cooking.

Pretty soon, though, he missed food. I was relieved when he went back to eating real food,

but it begs the question, could a person eat nothing but vitamins and survive?

We heard from a few listeners wondering about the same thing.

I'm Heidi. I'm Alice. I'm a runner. I'm Naomi. I'm from Cleveland, Utah. And our question is, if you took enough vitamins every day, could you live without food?

So the short answer is you definitely cannot survive just by eating vitamins every day or

vitamins of water every day. My name is Craig Sherwin and I work for a company called

Nova Zimes and we're a Danish company that provides enzymes that are used in all sorts of different foods and beverages.

My specific title is called Technical Service Manager.

So first, let's talk about what we mean when we say eating vitamins every day, because we think of vitamins as the pill that you pop in your mouth.

But actually, what's in those pills are also called vitamins.

So those are the actual nutrients themselves are called vitamins.

And they're usually delivered in a vitamin pill.

So these vitamin pills are really tiny compared to eating a full meal that we would ever have.
