And that stems from the Greek term for sugar.

And there's two main kind of forms of saccharides that we talk about in nutrition.

There's what we call monosaccharides, which are the very simple sugars that are made up of one sugar molecule.

And the key ones that are relevant to us are glucose, fructose, and galactose.

So they're just single sugar molecules.

Then you have something called disaccharides, which are basically two simple sugar molecules joined together.

So you have sucrose, which is what's really common table sugar, the sugar that you're adding to your tea, for example.

And that's made up of a glucose molecule joined to a fructose molecule.

And then you have, for example, lactose, which is the sugar that's commonly found in milk.

And that's made up of a glucose molecule with a galactose molecule.

So we need sugar in our blood to survive, but we actually don't need to consume sugar to survive.

And that's really, really important to remember.

So our cells need sugar.

Our cells need glucose, for example.

We need sugar in order to fuel our cells.

We need it for our brain.

Our brain preferentially uses glucose as its energy source.

But actually, we can make sugar in our bodies.

So we can use a certain process in our body where we convert protein

into sugars, into glucose, for example, where we can also, to a lesser extent, also convert fat into sugars, into glucose.
