Your gut has a wall made of cells held together by tight junctions. A molecule called phytic acid, found in beans and whole grains, turns on a protein (HDAC3) that keeps these junctions strong by turning off harmful enzymes (MMPs) that break them down.

Max 72Case-Control Studies
Max 58Cross-Sectional Studies

Phytic acid triggers a molecular process in intestinal cells that reduces the activity of enzymes involved in breaking down the intestinal barrier, leading to a stronger barrier function.
At a concentration of 10 nM, inositol hexaphosphate enhances the enzymatic activity of HDAC3 in laboratory cell-free systems by promoting the interaction between the DAD domain of a corepressor complex and HDAC3, without requiring IPMK to be physically present.
In people with inflammatory bowel disease, specific proteins and enzymes in colon tissue are found at lower levels, while other molecular markers associated with tissue remodeling are higher, similar to patterns seen in mice genetically engineered to lack IPMK.
In laboratory studies, InsP6 activates the HDAC3 enzyme more effectively than other similar molecules, restoring more than half of its activity at a very low concentration (10 nM) in cells lacking IPMK, whereas InsP4 and InsP3 have little to no effect.
When histone deacetylase 3 (HDAC3) does not function properly, it triggers the expression of specific genes that compromise the integrity of the intestinal lining and promote inflammatory responses.
