When salmon is processed to remove its fat and combined with purified fish oil, the fat empties from the stomach more quickly and less omega-3 enters the bloodstream compared to eating whole or...
Mechanism
Synthesis from 1 study
Whole salmon keeps its fat locked inside its tissue, so it digests slowly and lets your body absorb more omega-3s. When the fat is removed and mixed with oil, it rushes through your stomach too quickly, so less gets absorbed.
Most probable mechanism
When you eat whole salmon, the fat stays trapped inside the fish's tissue, so it leaves the stomach slowly. This gives your body more time to break down the fat and absorb the good omega-3 fats into your blood. But when the fat is pulled out and mixed with oil, it leaves the stomach too fast, so your body doesn't absorb as much.
The physical structure of intact salmon resists rapid disintegration in the stomach, maintaining lipid encapsulation within cellular and tissue matrices.
Delayed gastric emptying of lipid-rich phases reduces the rate at which omega-3 fatty acids are released into the duodenum.
Slower lipid release allows more time for bile salts and pancreatic lipases to emulsify and hydrolyze triglycerides into free fatty acids and monoglycerides.
Improved micelle formation and stability from sustained fatty acid release increases solubilization and transport of EPA and DHA across the intestinal epithelium.
Enhanced absorption leads to greater chylomicron incorporation and systemic circulation of EPA and DHA.
