Probiotics: Are They Really Necessary? | Talking Point | Diet

Probiotics are part of a larger picture concerning bacteria and your body — your microbiome. Think of a microbiome as a diverse community of organisms, such as a forest, that work together to keep your body healthy. This community is made up of things called microbes. You have trillions of microbes on and in your body. These microbes are a combination of:
Fungi (including yeasts).
Everyone’s microbiome is unique. No two people have the same microbial cells — even twins are different.
For a microbe to be called a probiotic, it must have several characteristics. These include being able to:
Be isolated from a human.
Survive in your intestine after ingestion (being eaten).
Have a proven benefit to you.
Be safely consumed.
