Why eating fish and nuts might help your gut stay strong
Omega-3 polyunsaturated fatty acids improve intestinal barrier integrity—albeit to a lesser degree than short-chain fatty acids: an exploratory analysis of the randomized controlled LIBRE trial

This study looked at women with a high cancer risk and gave half of them a Mediterranean diet full of fish, nuts, and veggies for a year. They measured how well their gut barrier worked — like checking if the gut wall is leaking.

In women with BRCA1/2 mutations, certain fatty acids produced by gut bacteria are more strongly linked to lower levels of markers indicating gut barrier disruption than omega-3 fatty acids from diet.
Over a year, following a Mediterranean diet is associated with a small increase in DHA levels in the blood and decreases in two biomarkers linked to intestinal barrier function in women with BRCA1 or BRCA2 gene mutations. These changes do not occur in women who do not change their diet.
Consuming omega-3 fatty acids from food is associated with reduced inflammation in the gut and stronger lining of the intestines.
In women with BRCA1/2 gene mutations, higher levels of the omega-3 fatty acid DHA in the blood are linked to lower levels of two biological markers that indicate a weakened intestinal barrier.
