Six Minute English from BBC Learning English.com

Hello this is six minute English from BBC learning English.

I'm Phil and I'm Georgie. Has this ever happened to you? You eat a

donut and get a sugar rush, a strong feeling of excitement and energy, only to

collapse an hour later with a headache.

Food affects us more than we realise and that's because what we eat

alters our brain chemistry, changing our mood and emotions. Our brain is working 24 hours a day even while

we sleep, so it needs more fuel than other body parts.

So, can we eat our way to feeling happy? In this program we'll be discussing the

relationship between food and the brain and as usual we'll be learning some

useful new vocabulary as well.

Sounds great Georgie, but first I have a question for you.

Humans with an average brain weighing one and a half kilos are one of the cleverest animals.

But which mammal has the biggest brain?

Is it A, an African elephant? B, a dolphin, or C a sperm whale.

I think it's an African elephant.

Okay, Georgie, I'll reveal the answer later in the program. Now, did you know that despite making up only 2% of our total weight, our brain uses 20% of the body's energy?

Nutritionist Dr Rita Achari 20% of the body's energy.

Nutritionist Dr Rita Achari does.

She thinks we should be specifically eating for our brains,

as she explained to BBC World Service Program, the food chain.

Eating every day, right, and eating a balanced diet.
