In a 2019 study from Michigan State University, researchers surveyed grass-finished beef from 12 US farms, analyzing fatty acids, minerals, and vitamins. Farms used all-grass diets, leading to an average omega-6 to omega-3 ratio of 4.1, far better than typical grain-fed beef's 20:1 or higher.

A 1966 study revealed that linoleic acid (LA), the main omega-6 fat in seed oils like soybean and sunflower, lingers in your body’s fat tissue with a half-life of ~680 days (~1.9 years). Men switching to high-LA diets saw adipose LA rise from 11% to 32% over 5 years, showing it takes years to fully reflect dietary shifts.

A 2018 editorial in Open Heart by DiNicolantonio & O’Keefe highlights that the typical Western diet—with high omega-6 and low omega-3 fats—promotes inflammation linked to heart disease and chronic illness. They stress the importance of keeping omega‑6/omega‑3 ratios low to reduce inflammatory signaling like platelet aggregation and oxidative stress.
