Do you know why you should eat more omega-3's?
Omega-3's are just part of the essential fatty acids that humans need to for their bodies to function properly. They are NOT produced by the body and therefore must come from our diet.
There are two types of fats that are essential for your health—omega-6 and omega-3 fatty acids. The typical western diet is overloaded with omega-6 fatty acids and deficient in omega-3s, upsetting a critical balance. Look at the graph below and you will see that fresh pasture has two times more omega-3 than omega-6 fatty acids. Grain and soy, on the other hand, have far more omega-6s than omega-3s.
Therefore, when you switch to grassfed products, you are helping to correct the gross imbalance in the western diet. Eating a balanced ratio of essential fatty acids is linked with a lower risk of cancer, heart disease, diabetes, obesity, and mental disorders. (To learn more about this essential balance, read The Omega Diet by Simopoulos and Robinson, HarperCollins 1999.)

Another wonderful article about the fats (and CLA, Vit E, etc. found in grass-fed meats) can be found at EatWild.com. The article is too long to post in it's entirety here and the author, Jo Robinson, has given her permission to use the article as long as the entire article is posted, in order to maintain the context. We highly recommend it! Do yourself a favor and take a look!
