I investigated with my commercialy available software for w3 and found
that it was not possible to reach the w3 amounts and w3/w6 ratios as
recommended by the lituratures that I used without flax.
Summary

By using meats, vegetable oils and margarines, (menu 1) we get enough
w3, but w3/w6 ratio is very low (1/17). The only way to raise it to a
higher level is with flax.

By replacing meats, vegetable oils and margarines with eggs, cheese,
fish, olive oil and butter, (menu 2) we do not get enough w3 (1.2g),
and our w3/w6 ratio is too low (1/6). The only way to raise it to the
optimal 2/1 is to use flax.

By including flax in our low fat diet in the same amounts like we use
other cereals, (corrections in menu 2) we can get enough w3 (3.2g),
and our w3/w6 is (1/3), above the minimum adequate level recommended
(1/4). The only way to raise it up to the optimal ratio of 2/1 is to
use more flax.

Conclusions

In the modern (w3 poor) diet we must include flax to ensure that we
get the RDA for w3 and at the same time reach an acceptable w3/w6
ratio.

What was shocking for me isn that to correct for a typical high fat
diet, almost 4 cups of flax seed had to be consumed per day. To
correct for a low fat diet, 1.25 cups of flax seed had to be used per
week.

I request my paper to be reviewed and to see if it can be refuted.
