﻿ Probiotics: Find Out About the Benefits and Side Effects

What are probiotics?

There are very few people who have not heard about the "new" health miracles called probiotics. They claim to help with health problems, ranging from constipation to diarrhea, and prevent colds or fight them once you already have one. Probiotics are showing up in foods, beverages, and supplements. What exactly are they, do they work, and are they safe for us to be consuming?

Let's start with the facts behind what probiotics are. The root of the word probiotic comes from the Greek word pro, meaning "promoting" and biotic, meaning "life." There is some debate about how to define probiotics. The Food and Agriculture Organization of the United Nations (FAO) defines probiotics as "live microorganisms, which, when administered in adequate amounts, confer a health benefit on the host." Yes, they are actually alive, and most of these microorganisms are bacteria. Most people think of antibiotics and antibacterial products when you mention bacteria. Both of those kill bacteria so why would you want to consume anything that has live bacteria in it? It's all about balance.

Our digestive system normally has what we would call "good" bacteria and "bad" bacteria. Maintaining the correct balance between the "good" bacteria and the "bad" bacteria is necessary for optimal health. Things like medications, diet, diseases, and your environment can upset that balance. Is your body able to handle this on its own or do you need to start including probiotics in your diet? This article will help you decide.

What is the gut?

A "gut feeling" or a "gut reaction" to something is a description of a sense you have about it without knowing why. This probably comes from the fact that many people experience their emotions in their stomach or gut area. Think about where you would physically feel a "gut feeling." Research has shown that the network of neurons lining our guts is so extensive that is has now been nicknamed our "second brain" or "other brain." This gut "brain" doesn't think for us, but it does play a key role in certain diseases and communicates with the brain in our skulls.

Our "second brain" is known as the enteric nervous system. It is a collection of neurons in the gastrointestinal tract. Its role is to manage every aspect of digestion in all the organs of the gastrointestinal tract, including the esophagus, stomach, small intestine, and colon. It uses over 100 million neurons and some of the same chemicals things that can be found in your "other" brain, including neurotransmitters and neuropeptides.
