Daily Intake of Heat-Killed L. plantarum L-137 Augments Acquired Immunity in Health Adults
The benefits of probiotics are derived not only from their living functions, but from their ability to modulate our immune system beginning from the gut. A large chunk of the control of our immune system starts in the gut (as much as 2/3 depending on who you talk to) and this then sends out the signal to the rest of our immune system.
It’s one of the reasons why persons w/ celiac disease (allergy to gluten in grains) have a higher overall mortality rate if they continue to eat gluten. This activates the immune system, leading to an overall increase in systemic inflammation. Systemic inflammation slows beats up our bodies, increasing the risk of chronic diseases.
