In this section, the speaker explains what the microbiome is and why it is important for our health.

What is the Microbiome?

• The microbiome refers to the community of gut microbes in our intestines.

• It consists of thousands of different species that coexist in our lower intestine or colon.

• These microbes produce chemicals vital for our immune system, including key vitamins like B vitamins and neurochemicals like serotonin.

Importance of Microbiome for Health

• Most of our immune system is actually located in our gut.

• The immune cells are constantly communicating with our gut microbes through chemicals produced by the microbiome.

• The microbiome also affects brain function and can impact mood, appetite, and overall health.

The Importance of Gut Health
