Sucralose
Researchers publishing in Journal of Toxicology and Environmental Health, Part B have found that the common sweetener sucralose may contribute to genetic and intestinal damage [1]. Not the only study of this kind This paper begins by stating the fundamental claims that were made prior to the approval of sucralose by the FDA. Those claims...
Bacteriophages
Researchers publishing in Nature Microbiology have determined that the viruses populating the intestines of centenarians are slightly different from those of the merely old. Viruses for bacteria, not people We have written previously about a study showing that centenarians have youthful bacterial gut compositions (enterotypes) similar to those of younger people. This study looks more...
Intestinal molecules
Scientists have shown that the NAD+ precursor nicotinamide riboside (NR) alleviates symptoms of leaky gut caused by ethanol consumption in mice by improving mitochondrial function [1]. Nicotinamide Riboside (NR): Benefits and Side EffectsNicotinamide riboside (NR) is a B3 vitamin. Nicotinamide riboside gets converted into nicotinamide adenine dinucleotide (NAD+), a coenzyme essential for life.Read MoreCategory: Supplements...
Mice eating
According to a new study, the age-related increase in intestinal permeability that drives inflammation can be alleviated by inhibiting the enzyme arginase, a regulator of nitric oxide production [1]. Gut feeling While age-related sterile inflammation (inflammaging) is considered one of the hallmarks of aging and a major cause of age-related diseases [2], scientists still don't...
Journal Club
Journal Club returns live on our Facebook channel on October 25th at 12:00 Eastern time. Dr. Oliver Medvedik will be taking a look at a recent study published in Nature Aging that has shown that short-term rapamycin treatment in early adulthood extends lifespan in flies and improves gut health in both flies and mice [1]....
Young and old mice
A study published in Nature Aging has shown that short-term rapamycin treatment in early adulthood extends lifespan in flies and improves gut health in both flies and mice [1]. A well-studied drug Rapamycin, an inhibitor of mTOR signaling, is capable of extending the lifespan of several organisms and is thus believed to be one of...
