Many of us think of “corn-fed” beef as nutritionally superior, but it isn’t. A cornfed cow does develop well-marbled flesh, but this is simply saturated fat that can’t be trimmed off. GRASS-FED meat, on the other hand, is lower both in overall fat and in artery-clogging saturated fat. A sirloin steak from a grainfed feedlot steer has more than double the total fat of a similar cut from a grassfed steer. In its less-than-infinite wisdom, however, the USDA continues to grade beef in a way that rewards marbling with intra-muscular fat. A few more items to note:
Grassfed beef not only is lower in overall fat and in saturated fat, but it has the added advantage of providing more omega-3 fats. These crucial healthy fats are most plentiful in flaxseeds and fish, and are also found in walnuts, soybeans and in meat from animals that have grazed on omega-3 rich grass.
In addition to being higher in healthy omega-3s, meat from pastured cattle is also up to four times higher in vitamin E than meat from feedlot cattle, and much higher in conjugated linoleic acid (CLA), a nutrient associated with lower cancer risk.
As well as these nutritional advantages, there are also decided environmental benefits to grassfed beef. According to David Pimentel, a Cornell ecologist who specializes in agriculture and energy, the corn we feed our feedlot cattle accounts for a staggering amount of fossil fuel energy. Growing the corn used to feed livestock in this country takes vast quantities of chemical fertilizer, which in turn takes vast quantities of oil. Because of this dependence on petroleum, Pimentel says, a typical steer will in effect consume 284 gallons of oil in his lifetime.
From a humanitarian perspective, there is yet another advantage to pastured animal products. The animals themselves are not forced to live in confinement. The cruelties of modern factory farming are so severe that you don’t have to be a vegetarian or an animal rights activist to find the conditions to be intolerable, and a violation of the human-animal bond. Pastured livestock are not forced to endure the miseries of factory farming. They are not cooped up in cages barely larger than their own bodies, or packed together like sardines for months on end standing knee deep in their own manure.
