As scientists study the trillions of bugs, most of them bacteria, living in our intestines—known as the “gut microbiome,” they’re finding that this 3-5 pound community of microbiota has important roles in just about everything that goes on in our bodies. Some scientists are even saying our microbiota may be more important than our genes in determining our health or lack thereof. Recently, they’ve discovered that gut microbiota are intimately involved in determining blood pressure. It’s well-known that excessive salt intake isn’t good for the heart and has been associated with elevated blood pressure. Studies done in the last few years indicate that it’s how salt influences the microbiome that ultimately affects blood pressure. A 2017 study found that when either mice or humans ate too much salt, good bacteria in the gut started disappearing while pro-inflammatory immune cells called TH-17 cells started to rise; and as they did, they raise…

We each have a mighty force of trillions of tiny microorganisms—helpful bacteria and other microbes—living on our skin, in our digestive system, and in tissues throughout the body, that is constantly on guard to defend us against potentially invasive infectious disease-causing pathogens like viruses, yeasts, parasites and harmful bacteria. Discounted for many years by the medical establishment, scientists are now beginning to discover how much we depend on these “good bugs.” Not only do they synthesize vitamins and amino acids and help us to digest and absorb our food, they are also an indispensable part of our immune system. Before a pathogen—bacterial, viral, or fungal—can get into your bloodstream, where it can replicate and become increasingly virulent, it must first get past the formidable fortress created by your skin and mucus membranes. The skin isn’t just a physical barrier; it is an immune system organ, where immune cells and good bugs work together to conquer pot…
