Why we are Deficient in Fatty Acids and How Much do we Need?

It doesn't seem fair that we have to frequently supplement our foods when we should be able just to eat the real food and get enough but it's a reality. (Check out this Prevention article as to how this evolved with the fatty acid issue)

The problem involves an imbalance. This can cause many hormonal and chemical problems. It is estimated that about 90% of the American population is lacking in omega-3 because we consume so many processed foods and grains that are grown with omega-6 sources. Some authorities suggest approximately 10%-20% of our total caloric diet should consist of omega-3 essential fatty acids. Other researchers say we should have at least a 1:1 balance and still others suggest a 3:1(omega-3's to omega-6's).

So how much do we need exactly? This depends on numerous factors. In my own studies at Bauman College, it was suggested to consume 1,000-2,000 milligrams daily of omega-3’s for maintenance levels. Individuals with severe heart problems or other major health issues may need more, but this should be clearly monitored by doctors. We do know men need more, and certainly stress and disease affect how much we require. Note though, by consuming too many bad fats (and the 6's) increase the need for the omega-3’s. Eating three to four ounces of wild (not farm raised) salmon two times a week would constitute a sufficient amount of omega-3’s, unless one was eating an overabundance of omega-6’s from processed foods and/or consuming more grain (instead of grass fed animals) which would contain higher levels of omega-6.

Thursday I will elaborate more on where we obtain better quality omega-3 sources besides fish and how to take them so you don’t “burp” them up (a most common complaint I get from people who attempt to take them).

  1. Hello
    As a long time follower of yours from back to Nutrition Data, I always seem to learn new things. You have helped me through loosing 40 pounds and am learning how to eat better. Like this fish oil thing I had no idea that I needed that much. I know that anything wild is better but can you explain a little more about why the farm raised salmon is so much higher in the omega 3s than farm raised. Seems like fish is fish is fish.

  2. Hi,
    Thank you for that question. If you review the Prevention link above it explains a bit about that. But in a nutshell, farm raised fish usually are fed sources that have more omega-6's and other additives that are not always good for us. An animal's nutrition intake will have a different effect when fed the wrong foods, just like people. Also note that smoked salmon has less omega-3's because it dries up much of the oil, and frequently contains nitrates or nitrites which are not good for us either.-Elaine
