Why is grass-finished beef healthier? – As you may know, cows have ruminant stomachs. This means that when they are grass-fed, they can effectively break down grasses into nutrition for their best health. Conversely, cows that are grain-fed suffer, as the grain doesn’t digest well, provides inadequate nutrients, and can increase the risk of illness and infection. These reduced nutrients and inflammatory problems are then passed on to you when you eat it. After all, you are what you eat, but also are what you eat has previously eaten.
