But the chances are with those three is that they are quite energy dense. So they have quite a lot of calories per gram, which is partly because of the processing techniques. Yet if you take a whole food like a nut, now they're actually very energy dense. So they're very high in fat. They're high in calories.

But actually, because they're in their original food matrix, how your body handles them is quite different to if, for example, they had been processed.

Yeah, so there's lots of different mechanisms that impact how full we feel, how hungry we feel related to a food. There's different hormones that are released from different areas of our gut, for example, that feedback signals to say either you're full or you're hungry. On average, I would say it takes about 10 to 20 minutes for the fullness to really properly kick in.

Now, you could easily have got through those. Well, I could easily have got through all of these in under that 20 minutes.

So there are many people who will say the food industry has specifically designed these to make them firstly what we call hyperpalatable. So to have the right mix of fat, sugar, you know, carbohydrate, etc. To make them really tasty and in this case salt as well. I don't think the food industry is out there to get us.

I think that what the food industry were doing 50 years ago versus what they're doing now is quite different. but some people will say I'm very naive. I do believe the food industry ultimately want to produce food that's safe but also healthy for us. That's probably an unpopular opinion, but based on my interactions with the food industry, I believe that.

However, I do believe that these crisps are there, have been made to be flavoursome, to be palatable to you, so that you do enjoy them. Now, whether that's that you then go and overeat them, I think is, yes, a by-product of that.

um now it's not it doesn't take 20 minutes for all of the fullness signals to kick in because as soon as you start chewing something you start to release different hormones and different sensory characteristics of the food will also trigger some sort of fullness but what we do know is that you have more of these fullness receptors saying hey you're full lower down in your

If you can get food to the lower gastrointestinal tract, that's when it says, hey, Stephen, you're full now. And these heavily processed snacks that you've got here would be typically absorbed higher up the gastrointestinal tract because kind of the hard work's been done.

And yet when you've got something like a whole grain or a nut, typically that would be absorbed lower down the gastrointestinal tract where you've got more of these fullness signals. So giving you that greater feeling of fullness.
