>> Hi there, it's good to be back. Did you know when it comes to the number of cells that make you up you're mostly microbes and bacteria? Okay, before you get grossed out, deny that it's true or shower extensively, let's examine how these bacteria got a bad rap in the first place. Bacteria have long been thought to be the root cause of disease. But most of our research has been around pathogens, the bacteria or viruses that cause disease. Before we blame bacteria, it was originally thought that bad air was the culprit. This was the time when sanitation wasn't great, streets were filled with cesspools, and it was thought that the foul stench was why people were getting sick. Well, this was partially true. It was due to the bacteria and sewage that was being poured into the street. The prevailing idea back in the day was that disease was not passed person to person but by the environment. Germ theory, the idea that disease is caused by bacteria or microorganisms in the body was first proposed in 1546 by Girolamo Fracastoro, an Italian scientist. But this idea really didn't take root until the 1860s when Louis Pasteur and Robert Koch brought the idea into the main stream. You may have heard of Louis Pasteur, the inventor of pasteurization, a process that kills bacteria. Pasteurization is the process of heat treating many of our products so that they're shelf-stable. Pasteur was the first to prove Germ Theory. A germ refers to a pathogenic organism, but looking at the word germ itself, it was originally proposed to mean beginning or formation of something, like the germ of an idea. Remember, we didn't know much about organisms in the body at this point. Pasteur first noticed that microorganisms cause food to spoil. He identified a microorganism as the root cause of a silkworm disease which saved the entire silk industry. So germs were quickly labeled as the troublemakers and Pasteur was the savior. Germs then became known as disease causing pathogens that could spread from person to person. In 1876, Robert Koch continued to prove that microorganisms were at fault. He proved that anthrax, cholera, and tuberculosis were all caused by germs. And then he created a series of rules to identify germs called Koch's postulates. There are many pathogens that don't fit into Koch's criteria, but they were a critical step to identifying the cause of disease. In response to the germ theory, soap became a necessity rather than a luxury. Doctors started washing their hands and many lives were saved due to reduced infection during surgery. This discovery then led to a large focus on developing antibiotics, rightly so, because there was an epidemic of infectious disease. By eradicating bacteria, we hoped to end disease. Germ theory sent us down a path of eradicating as many bacteria and germs as possible with antibiotics, hand-sanitizers, soap, and sanitation. People wanted everything to be clean. But microbes vastly outnumbered us, and not only did we kill the bad but the good too. It would be difficult, if not impossible, to get rid of our microbial friends. And given the amount of good they do for us, we might be getting rid of ourselves too. As it turns out, our relationship with bacteria not only keeps us healthy but it's also essential to our survival. Until recently, we've been pointing the finger at bacteria for most disease. But now as we dive into the research around the human microbiome, we're learning the error in our assumptions. For example, H. pylori, a bug in our gut has been linked to cause of stomach ulcers and stomach cancer. So now based on germ theory, we tried to eradicate it. But now we're saying that it may have been foolish to try to eradicate an entire species. A lack of H. pylori in the body maybe linked to the rise of many other conditions such as Type 2 Diabetes, obesity, celiac disease, and other auto-immune diseases, and allergies. It appears that H. pylori is responsible for stimulating stomach acid and regulating ghrelin and leptin, telling your body when it's full or hungry. And here, we've been obliterating H. pylori for years. Rather than viewing microbes solely as pathogens, it looks like Clard Bernard may have been right. It may actually be that an imbalance in the ecosystem causes particular bacteria to act up. Who is Clard Bernard? He is the other guy, Pasteur's colleague, who believed that the ecosystem or environment the bacteria live in determine whether they become pathogenic or beneficial. We now know the bacteria in the gut play a role in regulating hormones, eliminating toxins, and even serve as an internal pharmacy by creating natural antibiotics. We've also learned that they are key influencers in obesity, diabetes, and directly affect the immune system. This is where you come in as a Health Coach with expertise in gut health. Help your clients strengthen and balance their microbiome to improve their health and help prevent disease. We can positively influence this community and keep a range of bacteria in the gut through diet, probiotics, or even sticking our hands in the dirt. On the flipside, we can negatively alter this community of bacteria and create dysbiosis or imbalance of bacteria with illness, stress, aging, bad dietary habits, the overuse of antibiotics, and our lifestyle choices. These are common everyday habits that most people struggle with but there are things are that you can help most people with and help them experience a greater quality of life. The biggest lesson the microbiome may have to teach us is that we can't simply put the blame on one thing is bad and then try and eradicate it. Think of how this might play out in other areas of your life. Adoption of a black and white mentality and swinging from one extreme to the other, after the introduction of soap, sanitation, and antibiotics, we've seen a steady decline in infectious disease. But now we're in an epidemic of chronic disease. What's chronic disease? It's disease that lasts longer than three months and generally can't be treated. Chronic disease eats away one's quality of life and takes a huge toll on our healthcare system. In the late 1980s, the Hygiene Hypothesis was introduced. This states that lack of exposure to germs may be responsible for suppressing the immune system. This is not to say that we need get sick more but that we need more exposure to good bacteria. There's also the idea that when the immune system is busy with other things, it doesn't have time to overreact as it does in the case of allergies or autoimmune diseases. So in summary, we've spent the last century viewing germs and bacteria as the villain and our bodies as the victims. As it turns out, we may have gotten it wrong. Disbelief let us to nearly eliminate infectious disease, which was a wonderful thing. But we're also now seeing a rise in chronic diseases. It's possible that we may have taken a good thing too far. We see now that it's possible to wipe out the good bacteria along with the bad. This may leave our bodies vulnerable to whatever is dominant in our environment. And this brings us back to the notion that health and possible treatment for chronic disease may lie in the health of our gut and gut bacteria. Do you use a lot of anti-bacterial products such as antibiotics, hand sanitizers, and anti-bacterial soaps? What's your experience been like with using these? Head on over to the Facebook page and share your experiences. There's so much we can learn from one another. That's all for now, see you soon.
