I am no expert but the thinking seems to be that monosaturates are more stable than polyunsaturates.
Some refined olive oils have as much as 50% omega six - so good quality oil is important.
Several reports suggest a small amount of saturated fat is ok eg 1% dairy. Some suggest very small amounts of other saturates beef palm coconut etc.
It is important to check lablels as everything tends to contain sixes (Including yes some olives in oil!) ( Almost all seed oils I have checked on except flax perillia are high in six and low in threes - canola has low sixes and some threes, and soy is high in si and has some threes) - and so if you are trying to balance threes and sixes it is almost impossible without cutting out high six seed oil which limits your options) AND grass fed ruminants are best as in the same way our fats are altered by what we eat the same applies to grain fed animals including fish - factors that have to be borne in mind at the same time as being practical about things.
Flax fish and greens are usually cited starting points - and as we can but have difficulty in making the omega three derivates found in fish oil EPA and DHA several books subscribe to fish oil to get a daily intake of about 2-3 grams of DHA EPA (5tps but check the label) (not cod liver which is different taken for other reasons)
The recent post below is a particulary powerful argument for balancing the threes and sixes.
As always whilst fish oil etc has few side effects except at high doses it is best to speak to you adviser about diet change - print out the article and show it to them - it might raise their eyebrows. It is also useful to check things for yourself - posts on this site the web books etc.
