Flaxseed oil, also known as linseed oil, has a very high level of 
alpha-linolenic acid (omega-3 fatty acid). This is exactly the 
omega-3's found in fish. One teaspoon of flaxseed contains about 
2.5 grams, equivalent to more than twice the amount most North 
Americans get through their diets. It also does contains omega-6 fatty 
acids (linoleic acid).  Omega-6's are the same healthy fats found in 
vegetable oils. Both of these essential fatty acids are very healthy fats. 
The "good and bad intake ratios" is pure nonsense. No acceptable 
research has shown any ratio to be detrimental. True vegetarians 
(non-flish eaters) may get very little, if any, omega-3's and a great deal 
of omega-6's, and they are, in general, a quite healthy subgroup of 
the total population..
