Fats 1:1 ratio question?

The question I have isn't exactly science based, but this is the best place I see for it.  Forgive me if it's been asked before, but I searched and didn't find it. 

I have no problem believing that a 1:1 ratio is what is best for us, but the rest of the 811 book is based off the most natural sources we have available to us, Fruits!!!!  While most fruits have a basic 1:1 ratio in fats, there are also very fatty sources (nuts, seeds, avocados) that we have available to us.  Those foods are all very high in Omega 6's, but only have a small amount of omega 3's.  Omega 3's are of course obtainable in large doses in flax seed, but fats from flax seed are mostly only digestible when they are ground.  So, while I believe Dr. Graham when he say's a 1:1 ratio is what's best for us, I'm not sure why.  My guess is that it stems from that ratio being present in fruit, but even that doesn't make sense to me because the fats from 100 bananas still doesn't compare to the fats just a cup of raw peanuts.  

Should we make it a practice just not to eat nuts, seeds or avocado's except on the rare occasion?  I know that we should eat them only sparingly on a day to day basis, but as I pointed out above, even then the balance of 1:1 seems unlikely without the use of ground flax seed. 

Maybe I'm over thinking this, but it's just something that was on my mind and I didn't see an easy solution.
