Four nutrition workhorses overview

Heart disease, dementia, depression, diabetes: what do these conditions have in common? Dr Will Bulsiewicz, a gastroenterologist and New York Times bestselling author, says the answer is inflammation. In today’s episode, Will explains the four nutrition workhorses that can reduce inflammation, heal your gut and supercharge your immune system - in as little as 24 hours.

We explore discoveries in Will’s new book, Plant Powered Plus, that explain the central role inflammation plays in health. You’ll learn which symptoms that seem unrelated, such as fatigue, skin breakouts, bloating, headaches, and joint pain, all share a common driver. You’ll also hear why he believes the gut and the immune system rise and fall together, and how a weakened gut barrier may keep the immune system on constant alert.

By the end of the episode, you will have a clear understanding of what inflammation is, how it can cause damage, and practical, food-first ideas to wrestle yourself from its clutches.

What’s one small change you could try this week? In your meals or your routine to help your body switch off “fight mode”?
