Gut bacteria actively participate in this immune activity... helping to send "messages" that down regulate inflammation in the gut, improving barrier function and fostering a gut environment that antagonizes potentially harmful bacteria.Probiotic bacteria also influence the nervous system in the gut and produce molecules such as short-chain fatty acids that have systemic effects.Research is making new discoveries every day, and while we are a long ways off of definitive answers, we are now more aware than ever that bacteria help influence overall health.Listen in as Desiree Nielsen, BSc, RD, joins host Lisa Davis to explain why probiotics are so essential for optimal health, as well as the best types of probiotic strains to incorporate into your everyday regimen.
