“Inflammation” is having a moment. From gut health influencers to brain longevity podcasts, everyone seems to be talking about inflammation. But behind the headlines is a powerful scientific truth: chronic inflammation is one of the most important drivers of aging and disease.
While acute inflammation (think: swelling after a fall or redness around a wound) is the body’s way of healing, chronic low-grade inflammation is different. It simmers quietly beneath the surface, contributing to:
Researchers have even coined a term for it: “inflammaging.” It refers to the low-level, persistent inflammation that accumulates as we age—even without infection or injury.
But there’s good news: lifestyle, and especially diet, can play a powerful role in reducing inflammation.
This inflammatory state can damage blood vessels, neurons, joints, and even mood regulation circuits over time.
Foods that reduce inflammation do so by:
| Food Group |
Why It Works |
