I’ve seen two “paleo-esque” plans for the PUFA content of a diet.
Approach 1: “moderate” omega 6s in the realm of 12-18 grams a day, and high omega 3s, 6-8 grams a day.
Approach 2: Low and Low: Omega 6s under 7 gs average, but omega 3s at only 2-4 grams a day.
The idea of the second model is that any excess PUFAs are bad for cells, and the main reason we need 6-8 grams of W-3s is to cancel out some of the effects of 12-18 grams of W-6s, but that if the W-6s are kept down around 7 (maybe 5-12 range) then all of the extra W-3 become unnecessary.
Another problem I have with approach 1 is, how does one get 6-8 grams of W-3s per day anyway. The best data I can find suggests that 100gs of fatty salmon has about 1.5 grams of W-3s. That would require eating 12-16 oz a day every day, or getting more from other sources. A gram of fish oil claims to have .3 g of W-3s though, and 100gs of has around 10 grams of total fat so maybe 100gs of Salmon has more than 1.5 grams of W-3. If the fat had the same proportion as fish oil it would be more like 3 grams per 100 grams.
Anway, if you had to choose, would you use approach 1 or 2?
