The cattle must eat grass, not grains. However, the farmers these days feed their animals, corn as well as soybeans, which simply fattens up the animals faster for slaughter.
However, more money for the cattle farmers and lower prices at the grocery store will mean lesser nutrition for the consumers.
Keep in mind, the grass-fed beef produces higher beta-carotene, omega-3s, vitamin E, calcium, potassium, magnesium and many more.
You can buy grass-fed beef that could be found in the specialty groceries, farmers’ markets and nationally at the Whole Foods. Usually, it is labeled for the reason that it demands a premium.
