And you already showed that my baseline blood sugar was higher than yours.

So even with your pairing, Sarah, and the fact that your blood sugar control is better than mine, isn't it?

I think when we've done these OE tests, it turns out that my blood sugar control is really quite poor.

And I remember the first time that I ever did this test with Zoe with my blood sugar sensor, this was the thing that blew my mind because I sort of thought like these oats, right?

They're really healthy for you.

And yet I was having this response, which was sort of as fast as when I just drank a sugary drink.

And it seems to me that what you're seeing there, Sarah, is even when you've mixed in those other things, that this instant oats is...

It feels like it's almost like you're having sugar with your yogurt.

What's going on there?

One of my biggest lessons from that experiment is that not all oats are created equal.

The more processed they are, the bigger the blood sugar spikes we tend to see.

A simple habit I'm taking into 2026 is to choose less processed oats, like steel-cut or plain rolled oats with no added ingredients, and to dress them up with plants, fibre, healthy fats and protein to help smooth out those spikes.

Repeated blood sugar spikes can contribute to chronic low-grade inflammation in the body.

And inflammation is at the heart of many conditions, including arthritis.

So next, I turn to Dr. Tomiko Katsumoto, Clinical Associate Professor at Stanford University, to help us understand the different types of arthritis and why joint pain is becoming so common.

What do you experience as a patient living with osteoarthritis or rheumatoid arthritis?

Arthritis is affecting more and more people worldwide.

And for many, the pain and stiffness can completely change daily life.

But there was some genuine hope from Dr. Katsumoto.

She walked us through a major trial that tested whether a comprehensive lifestyle program, including diet, movement, sleep, and stress management, could meaningfully improve symptoms for people living with arthritis.
