Who does this body belong to? Does it belong to microbiota or humans?

• Humans have 200 kinds of cells with 2,500 genes and 1,000 microorganisms with 3,300,000 genes in our bodies.
• Our immunity relies on a variety of microorganisms inside our intestines.
• Microorganisms live inside our intestines since we were born.

Microorganisms live in our bodies everywhere from our skin to the respiratory system. Most of them can be found in our digestive system. Different types of microorganisms affect to organ system in different ways. Some are pathogenic microorganism protectors. Some are food digestors or support the metabolic system and excretory system. Some support the immune system. Eating a variety of vegetables and fruits helps to form a variety of microorganisms.

All microorganisms in our bodies are called “Microbiota”. The term “Microbiome” in humans is often used to describe the microorganisms that live in or on a particular part of the body.

Our bodies form microorganisms from the day fetuses live inside amniotic fluid to the day fetuses deliver by spontaneous vaginal delivery. They support the metabolic system. For babies by c-section delivery, microorganisms form on their skin.

White blood cells also move microorganisms and keep them inside the mother’s milk. Babies get lactobacillus from breastfeeding. Mother’s milk also has prebiotics (microorganism food) named “Oligosaccharides” that give complete immunity to babies.

Mothers should eat a variety of vegetables and fruits to form many types of microorganisms inside the intestine and pass them to babies. They support the immunity system and help to keep babies strong for the rest of their lives.
