It is advised that the best ratio of omega 6 to omega 3 is about 2:1 and that the PUFAs (the above) should contribute a third of our fat calories.
The most important omega 3s are found in fish oils (EPA and DHA).
The problem - do we consume our omega 3 (in the ratio above) from flax oil from which the alpha linolenic acid can be converted to EPA and DHA at a rate of 3% daily or do we use fish oil?
Depending on our omega 3 source, our EPA/DHA levels will vary greatly. Maybe they will be too high with just fish oil, maybe too low with only flax oil, the flax oil may give extra benefits over the fish oil.
I have read Udo Erasmuses book and can’t find the answer. Can anyone help? From which sources of omega 3 is this ratio designed for?
