While it’s unclear which method of feeding livestock – grass or grain – is better for the environment, when it comes to nutritional value, there’s more consensus. Scientists agree that grass-fed animals can produce meat or milk that is richer in omega-3 fats, which are linked to a lower risk of heart attack and stroke. Products from grass-fed animals can also contain more conjugated linoleic acid (CLA), another type of beneficial fat, and some vitamins.
But does grass-fed food have enough of a nutritional edge to make a difference to human health? And can we get the same nutrients from less expensive food, seafood or even a plant-based diet?
