Why do Japanese have longer lifespan
Japanese fermented food has anti-aging effects because fermentation produces metabolites that modulate the gut microbiota. Gut is called the second brain as it interacts with all the organs in the body. Its modulation can affect the whole organism.
Nutrition and microbiota
Everything we eat goes through the intestinal tract. The nutrients present in the food interact with the microbiota present in our gut and can modulate it. Imbalance in the microbiota can cause diabetes, obesity, mitochondria malfunction...
This is why JAAN confers a lot of attention to what goes through our gut and how it interacts with the microbiota.
