Eating whole salmon leads to higher levels of omega-3 fatty acids in the blood over six hours than eating processed forms of salmon or fish oil supplements, because the physical structure of the...
Mechanism
Synthesis from 1 study
Whole salmon breaks down slowly in your stomach, letting the good fats leak out gradually so your body can absorb more of them. When salmon is mashed or mixed with oil, the fats come out too fast and your body can’t absorb them as well.
Most probable mechanism
When you eat whole salmon, its natural structure breaks down slowly in your stomach, which lets the healthy fats leak out gradually. This slow release gives your body more time to break down the fats into smaller pieces that can be absorbed into your blood. When the salmon is mashed or mixed with oil, the fats come out too fast and don’t get absorbed as well.
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.
