Meat and eggs are good sources of Omega-3s and it is critical that you get them from grass-fed and pasture raised animals, preferably fed pesticide-free and non-GMO feed.
Animals that are raised on factory feedlot farms are fed predominantly soy and corn that is also genetically modified. These foods are unnatural for these animals and they remain sick most of their lives. It also massively increases their Omega-6 to Omega-3 ratio so that these foods (meat, chicken, eggs, etc.) become pro-inflammatory.
In addition, these animals are usually pumped up with artificial hormones and, because they are sick, are given antibiotics. You ingest these toxins every time you go to a restaurant that serves factory farmed animal foods while simultaneously increasing your consumption of inflammatory Omega-6 fats. Sadly, this is most restaurants.
