The Greenwashing of "Grass Fed"

Did you know that cows in feedlots can be fed pellets of grass and be called "grass-fed"? Did you know that cows that live on pasture year-round can be fed corn and soy and labeled "pasture raised"? Did you know that farms with a grass-fed certification can feed up to 25% of other things like peas, lentils, and canola (which are classed as "pseudo-grains")?

Yup, we live in a crazy world of greenwashed labels. And this is why, if you want the most natural and nutritious food possible, it's so important to know your farmer.

At Miller's Bio Farm, we don't get certified for anything we don't absolutely have to. Sure we could be certified organic, grass-fed, pasture-raised, regenerative, GMO-free, etc. But, nope. We'd rather just provide you with tons of info on our site. We're an open book and give you the honest truth (have you seen the honest disclosures on nearly all of our products?). No greenwashed labels, here!

So, in that vein, here's the nitty gritty on what our cows eat.

What Our Cows Eat

Yes, we advertise that our beef, cow milk, and buffalo milk are "100% grass-fed". This is the easiest way to communicate the animals' diet to you. But, in reality, our cows aren't just eating "grass" (I mean, they couldn't be sustained off your front lawn). It's more complicated than that.

Our cows eat biodiverse pasture. They eat fresh pasture in the warmer months and dry pasture in the colder months. We know our cows do better on fresh pasture, because they produce more milk!

First off, we don't use any of the "cides" on our fields to limit plants and bugs from growing (we're chemical free!). So, there's a wide variety of flora that grows. Many plants may be considered weeds in your garden... and basically none of them are in the "grass" family. Cows love dandelion, plantain, mullein, yarrow, and mustard. Some cows stay away from like thistle. And some cows will eat onion grass (but we don't like it because it can change the flavor of the milk).

Second, our pastures aren't just "grass". Sure, we plant grass varieties like sudangrass and sorgham. But, we also grow a lot of alfalfa, which is a legume. It's a member of the pea family! Our dry pasture for the colder months has a mix of different kinds of plants in it.

How We Manage Soil Health

It's not just about what the cows eat, it's about the quality of the pasture. Not any old pasture will do. 

The health of the soil affects the health of the plants. The health of the plants affects the health of the cow. The health of the cow affects the health of the food. And the health of the food affects you! It all starts in the soil. At Miller's Bio Farm, we take soil health very seriously.

We farm regeneratively (you can learn more about what regenerative means to us here). That means that our soil is naturally replenished year after year. We do this in two main ways.

  1. Manure, manure, manure. As Aaron, the owner says, "Nothing builds soil like a cow." We fertilize the fields with lots of manure, and this adds so much back to the soil - nutrients, micronutrients, organic matter, and beneficial microorganisms.
  2. Specific soil testing and mineral additions. Our farms use the Albrecht method of soil testing. We work with a soil specialist to test many different areas of each pasture for dozens of things. Then, we add minerals back in (they're just crushed rocks) to give our soil the perfect balance. 

When you can maintain a perfectly balanced and healthy soil, you get better health all around - the soil, the plants, the animals, the people, and the planet!

A quick anecdote. A couple years ago, our farm ended up with an excess of manure. So Aaron, the owner, gave it to the next farm over. He spread his manure on half of his field and our manure on the other half. Then he planted the entire field with the same crop. Even though it's about a 1/2 mile away, the difference was visible. The plants grown on our manure were nearly a foot higher than the plants grown on the non-regenerative manure. Wow! What a testament to the power of good soil management.

What We Supplement With

Our cows mostly eat pasture. It's 98%+ of their diet. But, we do give supplements to the cows, too. This makes sure that they have enough energy and stay in optimal health. We give them a nutri-balancer with vitamins and minerals and probiotics. We also give them molasses (more in the colder months) for energy.

Another thing we give to the cows is homeopathic remedies. We use these both to prevent and treat any issues. 

Why Grass Fed (or should I say pasture fed)

Cows are ruminants (and so are buffalo). Their bodies are designed to digest plants, not grains. It's what nature intended. 

Feeding a natural diet (in addition to a healthy active lifestyle) keeps our cows happy and healthy naturally. This is a big reason we don't need routine vaccines, antibiotics, hormones, or any of that junk. Plus, 100% grass-fed (or should I say 100% pasture-fed) cows produce the most nutrient-dense milk.

What Do You Think?

Do you look for the "grass-fed" label (or any label for that matter)? Have you ever been surprised or frustrated to find out that the foods you thought were healthy perfection weren't quite what they seemed? What farming practices are important to you?

Raw milk or fermented dairy and lactose intolerance. Why might it help?

I was misinformed. At some point, I read that raw milk contains lactase. As it turns out, this is not true! It is true that raw milk contains many live enzymes that are inactivated during pasteurization. But, what about lactase? I’ve heard many anecdotal stories from people who are lactose intolerant... but can handle raw milk or fermented dairy. If raw milk, yogurt, kefir, or cheese doesn’t contain lactase, then why is that?

Our bone broth tested negative-ish for heavy metals 🥳 NATURAL AND CLEAN

Over the past few months a bunch of people asked us if we tested our bone broth for toxic heavy metals. When we get the same question a lot, we of course look into it. My first question was --- Is there an issue with toxic metals in bone broth? As it turns out, yes, there "can" be an issue! Heavy metals are naturally present in our environment. We need the "good" heavy metals to thrive: iron, zinc, magnesium, copper, etc. But, we can 100% do without the toxic heavy metals: arsenic, cadmium, lead, mercury, etc. Too many toxic heavy metals can lead to a host of pretty awful issues: nervous system damage, cardiovascular issues, cancer, endocrine disruption, kidney damage, and so on. Our body is designed to excrete heavy metals through urine (and a little bit through sweat, hair, and breastmilk too)... but only so much. There's a limit. If you're overloaded, your body will store those heavy metals in your bones, blood, tissues, and organs. Similarly, if an animal is exposed to heavy metals via food, water, air, dust, or soil, those heavy metals accumulate in the bones. Maybe the farm's soil or air is contaminated from a nearby factory. Maybe the pipes for the water has lead solder connecting them. Maybe the feed a farm is buying was grown on contaminated soil or processed on contaminated equipment.  And, of course, a main purpose of bone broth is drawing out as much as possible from the bones. If there are heavy metals in bones, they will make their way into the broth. This is especially true when you pre-soak with apple cider vinegar and simmer for 48 hours to make it thick and gelatinous (like our broth). And that led me to my second question --- Should I be concerned about every bone broth? Where is the fear coming from? Well... it seems it might be a little political. There was a study done in the UK in 2013 that scared a lot of people. It's titled "The Risk of Lead Contamination in Bone Broth Diets". This study found high levels of lead in organic chicken bone broth, which is quite concerning. And, in fact, this one study is still cited in articles written today! Let's dig a little deeper. Let's go farther than the short abstract. Here are the broths tested in the study and their test results for lead:  (9.5 parts per billion): Broth made from tap water plus skin and cartilage(7.01 parts per billion): Broth made from tap water plus bones(2.3 parts per billion): Broth made from tap water plus meat(0.89 parts per billion): Tap water alone cooked for the same amount of time as a control. But, they only used organic chicken from one farm. And, there's zero information about that farm, their practices, the feed, and the broth recipe. Did they use vinegar or wine in the broth? Was the chicken's water contaminated with lead? What was the quality of the feed and the soil? Were the chickens raised indoors or outdoors? So many unanswered questions! All we get is that it was one "organic chicken" that created a lead issue with broth. Another curious thing is that the broth with skin and cartilage contained more lead than the broth made with just bones. Bones are where lead is stored, so why wouldn't the broth made with bones only contain more lead? It's an odd result. Moreover, the abstract of the study specifically called out "bone broth diets" like GAPS and paleo. They even go so far as to write, "In view of the dangers of lead consumption to the human body, we recommend that doctors and nutritionists take the risk of lead contamination into consideration when advising patients about bone broth diets." That's quite curious. Why are they worried about these diets? Are the researchers anti healing through food? Who funded the research? Is it political? My opinion? This study is not comprehensive. It does not speak to all bone broths. But it does cover a potential issue if the water or animals are overloaded with heavy metals. What I glean from this study is that we need more research. We don't need fear to spread and people to stop drinking broth from this one study. Regardless of whether the fear was fabricated or legit, we tested our bone broth anyway. After all, it's always nice to validate that your food choices are as clean as you think. For Miller's, here were my concerns before testing: What if there's mercury in the fishmeal in our chicken feed?What if the soil that our animals live on is contaminated?What is the well water that the broth is made with is contaminated?What if the Celtic sea salt has lots of heavy metals? We got the test results back. I was super excited. But, I was also confused. At face value, it appeared that our bone broth tested NEGATIVE for arsenic, cadmium, lead, and mercury. You can find the test results right here! You'll notice that, for every sample, the results are "<0.01 mg/kg" and "<0.02 mg/kg".  I asked the lab what the "<" means. They said that it indicates their limit of quantitation (LOQ), the lowest concentration that can be accurately tested using the test procedure in that sample type. So the results simply report that none of the metals tested were found in the sample above the specific reporting LOQs. Whether or not they were present below this LOQ is information that is not provided by the test. When talking to the lab, I told them what we needed and assumed that this test would go below a 1 ppb. So, when the results came in, I assumed that a "mg/kg" was the same as a part per billion (ppb). Ummm... that math wasn't write! A "mg/kg" is actually a part per million (ppm). That means that the test we ran had results saying that the broth had less than 0.02 ppm (or 20 ppb) of arsenic and lead. And, it had less than 0.01 ppm (or 10 ppb) of cadmium and mercury. For some reference, the EPA says that less than 15 ppb of lead is safe in drinking water. Not saying that I agree, but it's a good reference point.  These results are good. It means the broth definitely isn't overloaded with toxic heavy metals. But, it's not good enough!!! We need to test again! We really need to a lower LOQ. We need to know the results with an accuracy of as low as 1 ppb. It looks like the lab we sent the original samples to doesn't have an LOQ that low. So here I am on the hunt for a lab to do it again. As soon as I can, I'll send samples in again and paying for more expensive testing to get the info you deserve. Stay tuned! I hope to have the new results in by the end of April 2025.
