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.

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.
