Flour. Oh flour. It always seems to be on the chopping block but never disappears. First, the trend was about cutting carbs. Now, it’s about being gluten-free. But, despite this, flour remains. Why? Well, it’s pretty awesome.

Humans have been grinding grain into powdery flour for an estimated 10,000 years. This practice allowed them to move to colder climates and have food through the winter (and it’s also important to mention that it’s pretty darn tasty, too).

Today, we have access to so many different foods and different types of each food and different labels on the food. In fact, Miller’s just released 7 new flour options this week! No labels, just all the nitty gritty details in the description. Because, well, we know the farmers :)

Let me shed some light on flour. Hopefully, it will make your process of buying flour easier.

Heritage Grains vs. Mass Market Grains

Mass market grains are developed and grown for resistance to disease and for higher yield. The idea is to more easily feed the world - a noble cause that seems to never be realized (because, come on, the uber-wealthy prefer to build spaceships instead). 

For example, corn has been genetically modified to be grown with synthetic chemicals that eliminate weeds and pests and produce larger ears with fatter kernels. Wheat has not been genetically modified in a lab. Instead, it has been intensively selectively bred to maximize berry production and size. The wheat we now know as modern wheat is far removed from its natural origins.

Heritage grains, on the other hand, are not modified in any way. They are ancient grains. They are non-hybridized. They have grown in popularity in the past decade because people seem to be able to digest them better, specifically those with a sensitivity to gluten.

Some examples of heritage wheat include einkorn, spelt, and red winter or spring wheat. 

Stone Ground vs. Factory Milled

Long long ago, humans ground grain in between two stones. Stone ground flour is the closest we can reasonably get to this ancient process. It grinds slowly and keeps the grain at a low temperature, therefore preserving a maximum of nutritional benefits. Factory milled flour happens at high speeds and temperatures. 

Whole Grain vs. Refined White Flour

When it comes to wheat, there are three parts of the berry - the bran, the germ, and the endosperm. The bran and germ are super nutritious. However, they also reduce shelf life.  

Whole grain flour has the whole berry with all three parts. It’s the most nutritious with the least shelf life. 

Refined white flour is just the endosperm, with the bran and germ removed. So, refined white flour is the least nutritious but the most shelf stable. 

And then there’s flour like we offer at Miller’s that’s half and half - there’s some bran and germ removed and some remaining. A good balance. Unfortunately, there’s no official term for this option. It’s something you need to ask the farmer. 

Bleached vs. Unbleached

Bleached flour is done with chlorine or benzoyl peroxide. It adds synthetic chemicals and damages the starch and protein content. Bleached flour became popular because it makes it softer, fluffier, and rises better. Unless you’re a pastry chef, unbleached flour should be delicious and work well in most home baked goods. 

Types of Flour

  • Whole Grains: The seed of the plant. With wheat, we call it a berry. With corn, we call it a kernel. With oats, it’s simply whole oats. If you have a milling system at home, you can purchase whole grains and make them into flour yourself!
  • All-purpose: This type of flour is a pantry staple and works well for basically all applications. It can be stone milled or factory milled or bleached or unbleached.
  • Bread: Is made with hard wheat. It has a higher protein and therefore more gluten, which results in chewy and elastic bread.
  • Pastry/Cake: Is made with soft wheat and is ground to a super-fine texture. It absorbs a lot of water, which results in great rising abilities. It is typically bleached, but some artisanal companies offer unbleached options.
  • Self-rising: A combination of all-purpose flour, baking powder, and salt. It’s typically bleached and factory milled. You may find this ingredient in pancake or biscuit recipes. But, hey, why not just add the baking powder and salt yourself?
  • Enriched: This is flour with nutrients added in that were lost in the growing, milling, or bleaching process. When you source from local farms that take good care of their soil and offer natural flours, enriched flour is not necessary.

I am stoked to announce that Miller’s launched 7 new flour options this week! 

They are all from Beiler’s Heritage Grains, about 11 miles from our farm. They grow their own non-GMO grains and stone grind it at low speeds on premises. Check out the new offerings below.

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.
