Grass-Fed Butter

What is grass-fed butter?

Butter is milk fat from cows that have been fed grass rather than grains.

Why butter from grass fed cows rather than grain fed?

The milk from cows that are fed grass is higher in:

Omega-3 fatty acids – reduce inflammation, important for cognitive function.

Conjugated linoleic acid (CLA) – helps burn fat, anti-cancer properties (jury is still out).

Vitamin K – helps strengthen bones and arteries.

How is grass-fed butter made?

Like all butter, it’s made from churning the cream or milk from the cow until the butterfat (which becomes butter as we know it) separates from the buttermilk.

What kind of grass-fed butter should I buy?

A brand that has the only ingredient being cultured pasteurized cream. Check packaging for indication that it is “grass-fed,” as that will not always appear under the ingredients. Also, buy unsalted so that you can control the amount of salt you are adding to your food. I always buy Kerrygold Pure Irish Butter – Unsalted (8 ounce) and freeze the extra blocks until I’m ready to use them.


It’s still butter, which means it’s all fat. Try to limit your intake to spreading it on toast, drizzling a bit over your popcorn, or in baking. You shouldn’t be going through a stick a week.
