Generally speaking, omega 6 is abundant in beef, especially, those fed with artificial feed made from corn etc while omega 3 is dominant in beef grass fed. The same findings apply to fish. Artificially grown fish is told to contain more omega 6.
I am sorry to say that American or Aussie beef contains much estrogen as growth promoter in addition to this fatty acid issue.
Since I knew of this info on nutrition, I have been trying to avoid omega 6 abundant items and to augment taking omega 3 rich foods. Another aspect of my personality says it won't matter with us at our age for now. But it is not meaningless to be aware of those food items promoting aging and aging related illnesses.
Here is such a menu. Cod fish as meuniere. This cod is naturally grown one.
It is a headache how to avoid imported beef in the menu. Japanese beef is too expensive. I wonder if chicken imported from Thailand is OK for this issue. Worry is not exhausted.
