And I think the evidence is quite consistent for that.

So Jonathan's has just gone up to 10.7.

I can't believe that.

Well, I can believe that, but I'm quite surprised.

Mine's gone up to 8.4.

So what's happening is the carbohydrate from the oats is being processed and broken down into glucose molecules.

And the glucose molecules are now passing through your bloodstream.

And this is what we're detecting from the glucose monitor that you're wearing on your arm.

So you're seeing this increase in circulating glucose from the carbohydrates that are in those oats.

And this increases within 5 to 10 minutes after eating any carbohydrate-rich meals.

Typically, it peaks around 30 minutes.

So it'll be interesting to see what it looks like in about 10 or 15 minutes.

Yeah, that's quite a big increase in blood sugar levels.

Now, an increase in blood sugar after carbohydrate-rich meal is a normal physiological response.

But once it starts to get really high, quite often it can impact how you're feeling in the moment.

So it might be that you have a slight headache or you might feel that your heart is racing a little bit.

Also, about two to four hours later,

after having quite a big peak like that, you might get a dip in blood glucose.

And we found from our own ZOE research that that dip can drive increased hunger, increased food intake.

It can give you poor energy, poor alertness.
