@LivelyReversal I don’t know but suspect not.
I’d first ask why should I want to eat more PUFAs? I eat oily fish occasionally: herring, sardines, anchovies, salmon. In fact, for a couple of years I ate herring about 4-5 times per week. But not so much any more. Even when I was eating lots more herring and other oily fish, my total caloric requirement was not lower. In fact, during that time frame I established my current maintenance ‘caloric window’.
My opinion is that our ancestors consumed whatever PUFAs were contained in the fats they ate in the various prey animals they hunted. And whatever those amounts, they are probably about what we have evolved to consume as part of a healthy diet. Granted, in certain environments fish were a more prominent dietary component than in others. Yet overall, I’d say that PUFAs are likely best consumed in the relatively small amounts contained in other animal fats - rather than eating oily fish exclusively, for example.
Have you got any citations of research indicating otherwise? If so, I’d like to see it. Thanks.
