Canadian scientists trap gut microbe fuel to improve blood sugar and liver health

A team of Canadian scientists has discovered a surprising new way to improve blood sugar levels and reduce liver damage: by trapping a little-known fuel made by gut bacteria before they wreak havoc on the body.

What’s better for your gut: lean beef or chicken? Science weighs in

A crossover trial in healthy young adults found that both lean chicken and beef diets reduced gut microbial richness, but only chicken caused significant diversity loss. The study highlights that lean local beef may have a milder impact on the gut microbiome than chicken.

How a leaky gut could be putting your heart at risk

Researchers reviewed recent studies showing that gut dysbiosis contributes to heart failure by weakening the gut barrier, enabling harmful metabolites like TMAO to trigger inflammation and cardiac damage. The review highlights a bidirectional “gut-heart axis” and points to new avenues for dietary and microbial therapies.

Research uncovers ME/CFS's systemic impact for targeted therapies

Millions suffering from myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), a debilitating condition often overlooked due to the lack of diagnostic tools, may be closer to personalized care, according to new research that shows how the disease disrupts interactions between the microbiome, immune system, and metabolism.

Gut bacteria send direct signals to the brain to stop you from overeating

Researchers have discovered a novel gut-brain sensory circuit in mice where specialized colonic cells sense bacterial flagellin and rapidly suppress feeding via the vagus nerve. This "neurobiotic sense" operates independently of immune pathways, revealing a direct neural mechanism for microbiota-host communication.

Research uncovers a 'neurobiotic sense' that lets the brain respond to gut microbe signals

In a breakthrough that reimagines the way the gut and brain communicate, researchers have uncovered what they call a "neurobiotic sense," a newly identified system that lets the brain respond in real time to signals from microbes living in our gut.
