Short Chain Fatty Acids News and Research

RSS

Butyrate and propionate are two important short-chain fatty acids (SCFAs) produced in the human gut. They have been shown to have significant immune system effects in the intestinal mucosa, by inducing the differentiation of T-regulatory cells via inhibition of histone deacetylase (HDAC). This enzyme keeps chromatin from unwinding and, therefore, inhibits gene transcription.

Gut microbiota and short chain fatty acids influence bone health in postmenopausal osteoporosis

Postmenopausal osteoporosis (PMOP) is framed as a systemic bone disease driven by estrogen withdrawal, but emerging evidence positions gut dysbiosis and its fermentation products—short-chain fatty acids (SCFAs)—as equally influential regulators of skeletal fate.

Mouth and gut microbes talk to each other - here’s why it matters for disease

Researchers reviewed nearly 250 studies to uncover how the oral and gut microbiomes communicate through multiple pathways, influencing the risk of diseases such as IBD, colorectal cancer, and cardiovascular disorders. The review highlights that maintaining oral health and dietary habits is crucial for overall systemic wellbeing.

New research reveals why fiber-rich diets fuel you better than refined foods

This study quantifies how much energy the human body harvests from gut microbial fermentation of dietary fiber, integrating bacterial physiology, diet, and metagenomic data. Results reveal that dietary fiber, not microbiome composition, mainly determines the amount of short-chain fatty acids absorbed, impacting daily energy and metabolic health.

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.

Looking for a natural way to lower blood pressure? Whole grains might be the answer

A new meta-analysis of prospective cohort studies found that higher whole grain intake is linked to a significantly lower risk of developing hypertension, with a 26% risk reduction observed between highest and lowest intake groups. In contrast, refined grain consumption showed no clear association with hypertension risk.
