It is OK to consume a lot of protein as long as the arachidonic acid content is not excessive. A few years ago I wrote an information sheet entitled "Consequences of feeding seeds to livestock". Here are the first three paragraphs:

(1919) “Seed mixtures, no matter how complex or what seeds they are derived from, will never induce optimal nutrition. The only successful combination of natural foods or milled products for the nutrition of an animal are combinations of seeds or other milled products with sufficient amounts of the leaves of plants.” (The Newer Knowledge of Nutrition by E.V. McCollum)

(1996) "Excessive signaling of arachidonic acid (AA) metabolites has been associated with various chronic degenerative or autoimmune diseases, and intervention with the metabolism of AA is widely employed therapeutically in these afflictions. In essence, AA is the most biologically active unsaturated fatty acid in higher animals. Its concentration in membranes and its magnitude of effects depend on its amount, or that of its precursors and analogues, in the diet. The tendency of the field of nutrition to ignore the role of dietary AA will optimistically be reversed in the future." The article also said, "The underlying rationale for this symposium is that dietary AA is perhaps the single most important nutritional determinant in regulating AA levels in Americans. This may ultimately account in part for the striking differences in chronic diseases between strict vegetarians and the bulk of the omnivorous population." (web search - Biological Effects of Arachidonic Acid: Introduction) https://pubmed.ncbi.nlm.nih.gov/8642436/

(2010) Chicken meat with reduced concentration of arachidonic acid (AA) and reduced ratio between omega-6 and omega-3 fatty acids has potential health benefits because a reduction in AA intake dampens prostanoid signaling, and the proportion between omega-6 and omega-3 fatty acids is too high in our diet.

Our daughter and her husband own a fitness gym. They gave me permission to leave copies of my information sheet at the front desk. A year later the manager provided feed back. He said that, after some discussion, he and his fellow weight lifters decided to shift their main protein source from chicken to beef and fish. All reported improved performance and less joint inflammation post workout.
