Hello, this is 6 Minute English from BBC Learning English. I'm Sam, and I'm Rob.

When someone feels sad or in a bad mood, they often try to feel better by eating their

favourite food. I usually go for a peanut butter sandwich myself.

Do you have a favourite comfort food, Rob?

Hmm, maybe a cream chocolate eclair.

Comfort food is a type of emotional eating, eating lots of food because we feel sad, not because

we're hungry.

But unfortunately, most comfort food is high in carbohydrates and sugar, and after a few

minutes, it leaves us feeling even worse than before.

Today, scientific research into the relationship between what we eat and how we feel is growing.

In this programme, we'll be investigating the connection between our food and our mood.

We'll hear how healthy eating makes us feel better, and of course, we'll be learning

some new vocabulary as well.

Great, but first I have a question for you, Sam.

People who link what we eat with how we feel make a simple argument. The food you eat

supplies nutrients and energy to the brain, and the brain controls our emotions.

Now that might sound simplistic, but the brain is a vital link in the connection between

food and our mood.

So Sam, my question is, how much of the body's total energy is used up by the brain?

Is it a 10%, b 20% or c 30%.

Hmm, that's a good question. I'll say it's a 10%.

Right, well I'll reveal the answer later in the programme.
