Most replayed moment: Can you really boost your immune system? | Professor Daniel Davis

25 de agosto de 2026 · 16m

Today we’re talking about the immune system.

It’s one of the most important systems in our body, yet it’s also one of the hardest to understand. You can’t see it, you can’t feel it working, and there’s no simple way to measure whether it’s strong or weak.

But when it fails, we certainly notice.

Everywhere we look, supplements and superfoods promise to ‘boost’ our immune system. But how many of these claims are actually supported by science?

Professor Daniel Davis joins me to explain how our immune system truly works, and what the evidence says is the best ways to support it.
