The widely approved guideline you would be talking about recommends people take in about 1.7g of omega-3 per day.
Uhm, I'm not entirely sure how this tangent relates to the discussion of saturated fat in yogurt which has little to do with omega-3, but whose recommendation are you referring to? This is what I found:
Many major health organizations across the world have issued recommendations as to the amount of Omega-3 EPA/DHA that should be consumed daily. While they all agree that EPA and DHA are important to overall health, the exact amount recommended varies by organization. The International Society for the Study of Fatty Acids & Lipids (ISSFAL), for example, suggests 500 mg of EPA/DHA for adults per day, which is similar to the recommendations of the National Institutes of Health of the United States (650 mg EPA/DHA per day), and The National Health & Medical Research Council of Australia (610 mg for men and 430 mg for women). http://www.meg-3.com/about/FAQ.php
My point was referring to your statement:
vary intake of different fats in accordance to some widely approved guideline
Well the guidelines that I displayed are telling you out of the 75g of fat per day they recommend, you only need 1.6g (sorry off by .1g) to be from omega-3 which is wayyy below the amounts that any of us recommend or the amounts people eat on a daily basis in other cultures.
That's your credible source? Wow, just awesome. A website selling an omega-3 product. I'm pulling my information from a book called "Contemporary Nutrition: A Functional Approach."
