Do Bacteria Contribute to Human Health? While it is common knowledge that our body is made up of more than 100 trillion human cells, not many humans know that it consists of about 10 times more bacteria and microbes that collectively constitute the human microbiome. These good bacteria are also healthy in the following ways:
DIGESTION The bacteria inhabiting your body help in breaking down the nutrients from food and supporting your digestive system. Additionally, many intestinal bacteria deliver a dose of essential B vitamins and vitamin K, which humans generally stay deficient of.
TOXIN CLEARANCE AND IMMUNITY BOOST The toxins in your body are also neutralized by these bacteria. This further helps with digestion and immunity boost. In fact, bacteria also help babies in fighting against hundreds of infections.
DISEASE PROTECTION Good bacteria in the microbiome provide defence against invading pathogens. There are various research studies that indicate the importance of bacteria in preventing humans from serious issues, such as gastric ulcers, obesity, inflammatory bowel disease, and colonic cancer.
WHERE ARE GOOD BACTERIA FOUND IN THE BODY? As there are such a large number of bacteria in the human body, they inhabit almost every body part, starting from nose and mouth to gut and skin. For over 3.5 billion years, these bacteria have been present as a life form. As humans evolved, they evolved alongside. As much as microbes need your body to survive, you need them to survive and stay in good health. It is all about mutual interaction for existence.
More than 1,000 species of bacteria and microbes make your skin their home. One of the beneficial bacteria that protect your skin against other harmful microbes is Bacillus subtilis. Bacteria in your nasal cavity usually impact the mucosal and systemic immune system’s reaction patterns, while those in the oral cavity inhibit harmful bacterial growth.
