Same thing.

One is high glycemic index.

One is medium glycemic index.

Same exact food.

The difference is the instant oatmeal is ground up into a very fine dust.

So again, pre-digested makes the digestion and absorption much faster.

And it's that quick spike of ultra processed foods, right?

Now, these are examples, not necessarily of ultra processing, but of cooking and so on, which makes a difference.

But the point is that when you get those big spikes, that's where you get into problems because you're getting the big spikes of insulin.

And how quickly you absorb makes a big difference because if you think about nicotine, for example, like when you smoke, the reason you smoke tobacco is that it goes from your lungs directly into the pulmonary blood vessels.

So you're basically getting directly into the blood.

When you take heroin, you inject it directly into the blood.

If you eat nicotine, so nicotine gum, it's much less addictive, right?

Same nicotine, same dose, but the speed that it gets absorbed is much slower.

So you take advantage of that and you, you know, use that when you're trying to wean somebody off.

But it's the same nicotine, but the way it's delivered.

And so it's the same with food.

When you have ultra-processed foods, you're getting this sort of pre-digestion.

So ultra-processed food, if you look at the characteristics, they tend to be very soft, easy.

It doesn't require a lot of chewing.
