Quick answer: Your gut, sometimes called the second brain, hosts trillions of microbes that help digest food, make vitamins and train the immune system. An anti-inflammatory diet rich in fiber, plants and fermented foods may support microbial diversity, a healthy gut barrier and balanced immune responses. Poor gut health is linked with inflammation and reduced nutrient absorption.
The second brain
The gut has its own nervous system and communicates with the brain. See the gut-brain connection.
A balanced microbiome
A diverse microbiome helps digest fiber, make short-chain fatty acids and some vitamins, and crowd out harmful microbes.
How diet supports gut health
Microbial diversity
A variety of plant foods feeds a variety of microbes.
Gut barrier
Short-chain fatty acids nourish the cells that line the gut. See causes of leaky gut.
Immune balance
Much of the immune system lives in the gut, and a healthy microbiome helps keep it balanced.
When gut health suffers
- More inflammation
- Reduced nutrient absorption
- Digestive symptoms such as bloating and irregularity
Healthy aging lens
Microbial diversity tends to decline with age; fiber, fermented foods and plant variety help maintain it.
