Significant amounts of Omega 6 are loosely linked to some inflammation - primarily with transfats/veggie oil. Other research shows both Omega 3 and Omega 6 from natural sources (including beef) are good for inflammation. Personally, I don’t find things not replicable to be very believable. Having personally done HFLC diet (and know plenty of other people with the same including most HFLC research) with plenty of grain fed beef and had my health shoot up and weight go down, I have a hard time buying what you are selling.
I am not “selling” anything. Grass fed beef and grain fed beef are completely different in appearance, taste and nutrition profile. People I know who have never tried grass fed are amazed at the flavor when they do try it. Many of the ranchers who do grass fed also avoid hormones and antibiotics. If one prefers “medical meat”, eat conventional :-)
