You absolutely need saturated fat for the omega-3 fatty acids to be utilized correctly. This is just biochemistry. You need them to get into fat burning mode (growth hormone) instead of just carb-burning (insulin resistance) mode.
I know this seems controversial but it's really just science that gets conveniently overlooked.
Here's an excerpt from a well-researched article with many footnotes:
* Saturated fatty acids constitute at least 50% of the cell membranes. They are what gives our cells necessary stiffness and integrity.
* They play a vital role in the health of our bones. For calcium to be effectively incorporated into the skeletal structure, at least 50% of the dietary fats should be saturated.38
* They lower Lp(a), a substance in the blood that indicates proneness to heart disease.39 They protect the liver from alcohol and other toxins, such as Tylenol.40
* They enhance the immune system.41
* They are needed for the proper utilization of essential fatty acids.
Elongated omega-3 fatty acids are better retained in the tissues when the diet is rich in saturated fats. 42
* Saturated 18-carbon stearic acid and 16-carbon palmitic acid are the preferred foods for the heart, which is why the fat around the heart muscle is highly saturated.43 The heart draws on this reserve of fat in times of stress.
* Short- and medium-chain saturated fatty acids have important antimicrobial properties. They protect us against harmful microorganisms in the digestive tract.
The scientific evidence, honestly evaluated, does not support the assertion that "artery-clogging" saturated fats cause heart disease.44 Actually, evaluation of the fat in artery clogs reveals that only about 26% is saturated. The rest is unsaturated, of which more than half is polyunsaturated.45
