Hi Andrew;

See the Essential Fat Comparison table. Quote;

"This second graph shows that grain-fed beef has a much higher ratio of
omega-6 to omega-3 fatty acids than wild game or grass-fed beef. A high
ratio of omega-6 to omega-3 fatty acids has been linked with an increased
risk of cancer, cardiovascular disease, allergies, depression, obesity, and
auto-immune disorders. (Simopoulos and Robinson, The Omega Diet, published
by HarperCollins in 1999.) A ratio of four or lower is considered ideal. The
ratio in grain-fed beef is more than 14 to 1. In grassfed beef, it is
approximately two to one.

(Data for both graphs comes from G.J. Miller, "Lipids in Wild Ruminant
Animals and Steers." J. of Food Quality, 9:331-343, 1986.)"
