New clinical research indicates that a widely used food additive, carboxymethylcellulose, alters the intestinal environment of healthy persons, perturbing levels of beneficial bacteria and nutrients.

Gut Bacteria May Point to Early Detection of Colon Cancer
“New research (from University of Washington School of Medicine) suggests that the presence of certain bacteria in a gut biome may be an indicator of colon polyps that will become […]
Phthalate and novel plasticizer concentrations in food items from U.S. fast food chains: a preliminary analysis
“… these are the first measurements of DEHT in food. Our preliminary findings suggest that ortho-phthalates remain ubiquitous and replacement plasticizers may be abundant in fast food meals.”
Effect of Long-Term Marine Omega-3 Fatty Acids Supplementation on the Risk of Atrial Fibrillation
“In RCTs examining cardiovascular outcomes, marine omega-3 supplementation was associated with an increased risk of AF. The risk appeared to be greater in trials testing >1g/d.”
Transmission of trained immunity and heterologous resistance to infections across generations
“Here we provide evidence for transmission of trained immunity across generations to murine progeny that survived a sublethal systemic infection with Candida albicans or a zymosan challenge. The progeny of trained mice […]
Identification of a choroid plexus vascular barrier closing during intestinal inflammation
“The inflammatory process causes the gut vascular barrier to become more permeable, resulting in the spread of inflammation beyond the intestine, while the vascular barrier in the choroid plexus shuts […]

Bifidobacteria-mediated immune system imprinting early in life
“Here we show that a lack of bifidobacteria, and in particular depletion of genes required for human milk oligosaccharide (HMO) utilization from the metagenome, is associated with systemic inflammation and […]
Microbiota from Young Mice Improve Cognitive Function in Older Recipients
“Conducting fecal microbial transplants from young mice to old mice, researchers were able to show a reversal of aging-associated differences and a slowing of cognitive impairments.”
Effects of early-life penicillin exposure on the gut microbiome and frontal cortex and amygdala gene expression
Exposing newborn mice to low-dose penicillin led to substantial changes in intestinal microbiota population structure and composition. Transcriptomic alterations implicate pathways perturbed in neurodevelopmental and neuropsychiatric disorders. There also were […]
