A new open access paper takes a look at tryptophan and the role that it plays in the dysfunction of the immune system in the context of the age-related changes that occur in the microbiome [1]. The microbiome The gut microbiome is a complex ecosystem of bacteria, archaea, eukarya, and viruses that live inside of…

Researcher Dr. Michael Lustgarten has recently published a compact and very readable review that focuses on the role of the gut microbiome and its influence on skeletal muscle mass. The gut microbiome The microbiome describes a varied community of bacteria, archaea, eukarya, and viruses that inhabit our gut. The four bacterial phyla of Firmicutes, Bacteroidetes,…

The relationship between health and the microorganisms living in the gut has increasingly reached the spotlight in the last few years, and a new study led by researchers at Nanyang Technological University, Singapore (NTU Singapore) sheds more light on the gut microbiome and how it can influence aging. The gut microbiome The gut microbiome is…

A new paper explores adjusting the types of bacteria in the gut as a potential way to improve health in older people. The microbiome The gut microbiome is a fascinating and diverse ecosystem filled with a myriad of bacteria, archaea, protists, fungi, and viruses that interact with each other and our bodies in diverse and…

A role for the gut microbiome on the health and functioning of many tissues, including the brain, liver, kidney, and adiposity, has been widely reported in the literature. Interestingly, 2019 might be the year that the role of the gut microbiome on skeletal muscle (i.e. the gut-muscle axis) comes into greater focus. The influence of…

In a recent study, a team from the Neurobiota Research Center in Korea has discovered that reducing gut dysbiosis partially alleviates the cognitive impairment associated with Alzheimer’s disease. This may seem puzzling, as the gut and the brain are separate and relatively distant organs, but this research makes sense in the context of chronic inflammation….

A new study has discovered that the guts of elite athletes contain a particular type of bacteria that boosts exercise capacity. The bacteria are members of the genus Veillonella and are not present in the gut microbiomes of sedentary people. The microbiome The microbiome is an ever-changing ecosystem in the gut populated by a vast…

In a small, recent human trial, a naturally occurring compound called urolithin A has yielded positive results and appears to slow down part of the aging process that is related to the production of energy in our cells. What is urolithin A? Urolithin A is the end product created when bacteria in the gut break…

The gut microbiome appears to be increasingly responsible for at least some of the decline of the immune system during aging, and a new mouse study shows that it is reversible. The gut microbiome The microbiome describes a varied community of bacteria, archaea, eukarya, and viruses that inhabit our guts. The four bacterial phyla of…

The role that the gut microbiome plays in aging is increasingly being appreciated in the research world as more evidence arrives to support it. A new publication reviews the various supporting evidence and takes a look at the gut microbiome in the context of poor diets and how they may facilitate the progression of dysbiosis…
