Grass-Fed vs. Grain-Fed

Why is it a big deal?

Here's a great article from ScratchMommy.com:

Until a few years ago, I had never thought of the differences in the quality of store bought vs. farm raised beef.  Being raised in a farming community, we were spoiled with usually have ½ a beef in the freezer.  Still, I was happy to pick up a roll of ground beef at the local store for a low $2.00 per pound.  However, after having our first baby, we started researching foods, which led to a very rude awakening. 

Before researching, I had never even considered the idea that factors such as the environment that a cow was raised in or what a cow ate may have an effect on our ecosystem, the nutritional content of the beef, and the way our bodies convert that nutrition into energy for use in our own bodies. But as I continued in my quest to improve the nutrition of my new little family, I began to realize that a side of beef is not a side of beef: the quality of meat does, in fact, matter for more than just my waistline, but my overall health as well.

I began to wonder, if we are what we eat, then aren’t we what we eat, eats?  

Take the example of a human nursing mother: If a mom eats a diet consisting of nutrient-dense foods such as whole milk, pastured eggs, avocados, beef liver,  and fruits and vegetables that are high in vitamins, minerals, and antioxidants, will the quality of her milk not be far superior than if she were to eat a diet consisting of candy, potato chips, and soda pop? Of course! I don’t think there’s a person in the world who would argue that. What she consumes has a profound effect on the quality of her milk. Likewise, what a cow consumes certainly has a profound influence on the quality of the beef it produces.  

After coming to this logical conclusion, my next matter of business was to educate myself on the implications of what this discovery meant. So, I set out to put myself through a crash course in all things grass-fed. Today I’d like to share some of the important information I found with you so that you can make educated dietary decisions for yourself and your family.

Terminology

What does the term “grass-fed” actually mean? Grass-fed (in terms of beef) means that the cattle were allowed to graze and forage for their food, which consists mainly of grass. In some climates during wintertime, it’s necessary to supplement the cows with a close substitute such as alfalfa, however the emphasis is still placed on allowing the cattle to graze freely as much as possible.

What does “conventionally raised” mean? Conventionally raised beef means that the cows were raised in feedlots or “CAFOs,” and fed a diet consisting mainly of grains, corn, and/or soy. What does “CAFO” stand for? CAFO stands for Concentrated Animal Feeding Operation. According to the EPA (Environmental Protection Agency),  “Animal Feeding Operations (AFOs) are agricultural operations where animals are kept and raised in confined situations. AFOs congregate animals, feed, manure and urine, dead animals, and production operations on a small land area. Feed is brought to the animals rather than the animals grazing or otherwise seeking feed in pastures, fields, or on rangeland.” 

What does “grass-fed, grain-finished” mean? Grass-fed, grain-finished means that the cow is allowed to graze for most of its life, but is “finished” or fattened on grains for the last 90-160 days before it is slaughtered. 

Is “organic” the same as “grass-fed”? The short answer: no. They are not mutually exclusive terms. According to the USDA (United States Department of Agriculture), in order for livestock to be considered organic, they must: 

  • Be fed agricultural feed products that are 100% organic (so nothing genetically engineered) 
  • Graze on pasture for not less than 120 days 
  • Not be routinely treated with rBGH (recombinant bovine growth hormone) or antibiotics 
  • Be allowed access to the outdoors year round with the exception of short periods of time for sickness or inclement weather. Source

From this you can see that simply because a beef product has the USDA Organic label, does not mean that it is grass-fed. Likewise, if a beef product is labeled grass-fed, this doesn’t mean that it meets USDA organic standards with regards to antibiotics and growth hormones.

BUT (and this is a big BUT), it is very common to find farmers producing grass-fed beef who utilize farming practices that would qualify their beef for the USDA organic label. However due to the cost of obtaining that label, they’re unable to do so. This is where it really benefits you to make friends with your local farmer. They’re usually more than happy to share their farming practices with you!

So now that we’re all working with the same set of terms, let’s talk about why one might choose grass fed over conventional...

There are loads of great reasons, but here are my top four:

Reason #1: Grass-fed beef is nutritionally superior to its conventional counterpart  

I’m not a calorie counting kind of girl, but if I were I would be happy to find out that grass-fed beef has fewer calories than grain-fed beef. In fact, a 6 oz piece of grass-fed beef has about 100 fewer calories than a 6 oz piece of grain-fed beef. Cows are fed grains for two reasons: 1. Grains are cheap. 2. They fatten the cattle up quickly and effectively, and we like our steaks nice and marbled with fat because fat is flavor, right?  

Grass-fed beef is higher in heart healthy omega 3 fatty acids. Source Omega 3’s may not only lower one’s risk of coronary artery disease, but also may help lower blood pressure. Additionally, there are some promising studies considering omega 3’s as treatment and/or prevention of cancer, ADHD, Alzheimer’s, and depression. 

Grass-fed beef is higher in CLA (conjugated linoleic acid) than conventionally raised beef — five times higher to be exact. Cows are ruminant animals. Ruminants have a digestive system that is vastly different from humans. They have four stomachs that are designed to digest the large amounts of cellulose in grass. When ruminant animals (cattle, sheep, elk, buffalo, goats, giraffes, camels) eat from pasture alone, they’re able to convert that grass to CLA. Why do we care about CLA? In addition to helping to regulate metabolism, fight obesity, and diabetes, there is also emerging evidence that CLA may help fight cancer! Source

Grass-fed beef is higher in vitamin E — about four times higher than feedlot beef. Vitamin E is a potent antioxidant. Antioxidants are important because they fight free radicals (free radicals are those things that attack your DNA and cause cancer). Vitamin E is also anti-aging and a potent immune system booster!  

Reason #2: Grass fed cows are healthier than feedlot cows.  

Conventional cows are packed into feedlots in quarters so close that they can’t even turn around. They’re given pounds and pounds of genetically engineered corn, soy, and grains daily in order to fatten them up for slaughter faster. They’re also given up to six different types of growth hormone to hasten the process. And because the conditions the cows are kept in are so unsanitary, the cows are often sick and require treatment with antibiotics.  

All of these things (hormones, antibiotics, genetically modified soy, corn and grains) are passed on to us when we eat the cow.

Reason #3: Grass fed farming practices are better for the environment.  Source

There are over 15,000 CAFOs in the United States, which generate millions of tons of manure every year.   The manure of these cows contains a number of potentially harmful pollutants including pesticides, hormones, antibiotics, nitrogen, and phosphorous. These pollutants leach into the ground water and surface water, significantly impacting water quality and aquatic life.  When cows are allowed to graze, the waste is not concentrated in single areas, but rather spread out over larger areas. CAFO gas emissions from manure decomposition also contribute to the reduction in ambient air quality.  

Reason #4: Buying grass-fed helps support small family farms.   

Of course there are some farms out there that are producing grass-fed beef on a large scale, and in all likelihood, when you purchase grass-fed beef from the grocery store, you’re getting beef from one of said large scale operations, or it has been imported to the U.S.  So this is the part where I encourage you to seek out your local farmers! The less distance your food travels to get to your plate, the better! In other words, eat local as often as possible!
