Start incorporating sardines into your diet! Their GI benefits are primarily derived from high content of omega-3 polyunsaturated fatty acids (PUFAs).
They include:
🐟Reducing intestinal inflammation via the following mechanisms:
-Suppression of pro-inflammatory signaling pathways including NF-kB, NLRP3 inflammasome, TLR4, and NOD2
- Reduction in pro-inflammatory cytokine production
- Generation of specialized pro-resolving mediators (resolvins, protectins, and maresins) that actively resolve inflammation
- Displacement of arachidonic acid from cell membranes, reducing production of pro-inflammatory eicosanoids
🐟Modulating gut microbiota composition
-A randomized trial in patients with type 2 diabetes found that consuming 100 g of sardines 5 days per week for 6 months decreased the Firmicutes/Bacteroidetes ratio and increased Bacteroides-Prevotella populations compared to baseline. A lower Firmicutes/Bacteroidetes ratio is generally associated with healthier metabolic profiles.
🐟Supporting gut barrier integrity
-Omega-3 PUFAs help maintain intestinal wall integrity through interactions with gut microbiota and immune cells.The interplay between omega-3 fatty acids, gut microbiota, and immune reactions supports the mucosal gut barrier and promotes intestinal homeostasis.
