'As a result ingestion of excessively high levels of saturated or monounsaturated fatty acids in order to assimilate enough omega-6 fatty acids is common'. 

What does that mean ? 

Does one require excessively high levels of saturated or monounsaturated fatty acids in order to assimilate omega-6 fatty acids? 

Or (excluding the issue of ideal Omega 3/6 ratio) is there a direct link between the intake/absorption of saturated, monounsaturated, omega 6, and omega 3 fatty acids, and if so, what is that link, and is it desirable or undesirable? 

I have re-edited part (as follows) - which you may wish to consider:

Triglycerides 

Excess saturated or monounsaturated fatty acids are unused and accumulate in the body in the form of triglycerides. 

Reducing triglyceride levels - Options

1. Moderate the consumption of saturated and monounsaturated fats, alcohol and carbohydrates
2. Aerobic exercise
3. Increasing the intake of omega 3 fatty acids (fish, and fish oil)
4. Reduce the intake of omega 6 fatty acids
5. Niacin (vitamin B3) megadose
6. Statins 
7. Fibrate drugs (with reservation, see following)

Carbohydrates 

Carbohydrate consumption increases insulin production, which in turn increases triglyceride production [4]. According to the American Heart Association, diets with carbohydrates constituting more than 60% of total caloric intake can increase triglyceride levels[3]. 
Exercise and reduced carbohydrate consumption prevent insulin overproduction. 

Omega 3/6 Ratio

Triglyceride levels are reduced by Omega-3 fatty acids from fish, flax seed oil or other sources. The recommended intake is 3 grams/day in US, and 2grams in Europe. Ideally, it should consumed in conjunction with Omega-6 fatty acids - but with the latter at much lower levels than typically found in Western diets.[5]
With the exception of Japan, most westerners have an omega-3 intake that is too low, and an omega 6 intake which is much too high - the ratio being about 12 in France, and up to 80 in caucasian US and Canadian populations.

Fibrate Drugs

Whilst fibrate drugs reduce triglycerides substantially, their side effects preclude their use as a first line treatment. One such drug, clofibrate has been withdrawn from the North American market because of the increased risk of mortality.

Alcohol 

Alcohol abuse can cause elevated levels of triglycerides.
