Cattle were not designed to eat grains. And because of that, their diet of grains in factory farms largely contributes to the negative aspects of eating beef. Cows by nature are naturally grass-grazing animals. When they are fully grown unfortunately the diets of most cattle, organic and conventional are switched from grass to grain in order to fatten them up and increase marbling. These grains can be genetically modified and often include corn and soy. Beef from cattle that are fed exclusively grass have more nutrients, less saturated fat and more omega 3 fatty acids than grain fed cows.
“Grain-fed beef can have an omega 6:3 ratio higher than 20:1” — J. Anim. Sci. 2000. 78:2849-2855
This well exceeds the 4:1 ratio where health problems begin to show up because of the essential fat imbalance. Grain-fed beef can also have over 50% of the total fat as the far less healthy saturated fat.
Grass-fed beef has an omega 6:3 ratio of 0.16 to 1.
This is the ratio science suggests is ideal for our diet. This is about the same ratio that fish has. Grass-fed beef usually has less than 10% of its fat as saturated. If you are a pregnant or breastfeeding mom, the extra omega-3 from the grass-fed beef will provide incredible nutrition to your child.
Compared to grain-fed cattle, grass-fed beef is:
