Consuming omega-3 fatty acids from food is associated with reduced inflammation in the gut and stronger lining of the intestines.
Mechanism
Synthesis from 1 study
Eating omega-3 fats helps the cells in your gut stick together better, so fewer harmful bacterial parts can leak out. This keeps your body from triggering unnecessary inflammation.
Most probable mechanism
When you eat foods rich in omega-3 fatty acids, these fats get incorporated into the lining of your gut, helping the cells stick together more tightly. This prevents harmful bacterial parts from leaking into your bloodstream, which in turn lowers inflammation.
Dietary omega-3 fatty acids, particularly docosahexaenoic acid (DHA), are absorbed and incorporated into the phospholipid membranes of intestinal epithelial cells.
Incorporated DHA increases the expression and stabilizes the structure of tight junction proteins, including occludin and zonula occludens-1 (ZO-1), between adjacent intestinal cells.
Enhanced tight junction integrity reduces paracellular leakage of bacterial endotoxins, such as lipopolysaccharide, from the gut lumen into systemic circulation.
Reduced endotoxin translocation decreases activation of innate immune pathways, leading to lower systemic inflammatory signaling.
