Don't eat a lot of nuts... but maybe you kinda miss them? I know I do. 

It's so much work to soak and dehydrate them at home (to get rid of the antinutrients). It's easier to just not buy them at all. If you want to purchase presoaked nuts, they're hard to find and prices can be crazy. And then of course there are PUFAs to consider.

I mean, don't you wish almonds didn't have a 2010:1 omega 6/3 ratio? Don't you wish walnuts weren't so ridiculously high in PUFAs? Don't you wish Brazil Nuts didn't have so many oxalates?

Enter macadamia nuts...

Macadamia Nuts are low in antinutrients and omega 6. They are a healthy nut.

Check out how they compare to popular nut options:

I mean, macadamia nuts undoubtedly come out of top.

Avoid antinutrients, PUFAs, and high omega 6 for the best health possible.

Here's an overview of what each is and why you should avoid it:

PUFAs 

PUFAs, or Polyunsaturated Fatty Acids, are a type of fat molecule composed of more than one double bond in their backbone. They are commonly found in many foods, especially vegetable oils like soybean, sunflower, and corn oils. While these fats are essential for our body in certain amounts (since our body can't produce them on its own), the modern Western diet has a disheartening imbalance of these fats, which can have potential health consequences (especially when PUFAs are oxidized): inflammation, oxidative stress, suppressed thyroid function, increased risk of heart diseases and certain cancers, and more.

Lectins

Lectins are part of a plant's defense. It keeps the seeds from being eaten by insects and animals so the plant can reproduce. Lectins are a protein, and they're sticky. They will stick to the intestinal lining and create inflammation and can lead to leaky gut syndrome. Lectins are also associated with insulin resistance and metabolic syndrome.

Oxalates

Oxalates are chelators. They bind to calcium and then you (usually) poop them out. If oxalate does not bind to calcium and you don't have enough liquid in your pee, then kidney stones will form. Oxalates can cause stress and cellular damage in your body. They can trigger inflammation, steal minerals, and destroy connective tissue. An oxalate overload can lead to a host of problems like kidney stones, arthritis, joint pain, and osteoporosis.

Phytic Acid

Phytic acid is an antinutrient. It's an organic acid that binds phosphorous within. It's found mostly in the bran or hulls of seeds. Untreated phytic acid can combine with calcium, magnesium, copper, iron and especially zinc in the intestinal tract and block their absorption. This is why a diet high in improperly prepared nuts and whole grains may lead to serious mineral deficiencies and bone loss. The modern misguided practice of consuming large amounts of unprocessed bran often improves colon transit time at first but may lead to irritable bowel syndrome and, in the long term, many other adverse effects.

Omega 6/3 Ratio

Omega 3 and omega 6 are essential fatty acids (also in the PUFA category) necessary for your health, and they can only be obtained through food. But, when eaten out of proportion, it can cause a plethora of chronic health issues: inflammation, heart disease, diabetes, obesity, arthritis, asthma, depression, fatigue... the list goes on and on. The modern American diet typically provides a shocking 20:1 omega 6/3 ratio. But, humans should eat a 1:1-4:1 ratio. We can only do this by being aware of our food choices.

Soaking nuts can remove antinutrients... but it's time consuming.

Soaking nuts, grains, seeds, and beans has been commonplace in indigenous cultures around the world for thousands of years. It's just what they do. It's likely a result of paying close attention to how your body feels (which is sadly getting lost in the modern word --- there's a pill for that, right?). 

Antinutrients are naturally in a nut for preservation. It helps prevent sprouting until the conditions are right - moist, warm, and slightly acidic. Proper preparation of nuts imitates the process that slowly occurs in nature (more on that below).

How to soak nuts:

  1. Put raw nuts in warm, salted water. You can add a little lemon juice or fermented whey to make the water acidic, too.
  2. Let them soak. The more the antinutrients, the longer you need to soak them to remove 100% of the antinutrients. Almonds should be soaked for a 8-24 hours. But, macadamia nuts only need 1-2 hours of soaking because of the low levels of antinutrients. Once soaked, you can eat them wet. Make hummus or add them to sauces. You can also re-dry them back into a crunchy nut for storage or snacking. 
  3. To dehydrate, spread the nuts on a tray (salting them if you'd like) and keep them between 110-150F. This can be in an oven, a dehydrator, or in the sun! This should take 12-24 hours. You know they're done when they're completely dry and crispy.
  4. Store in an airtight container.

The process of soaking nuts neutralizes phytic acid and enzyme inhibitors. Vitamin content increases, particularly B vitamins. Tannins, complex sugars, gluten and other difficult-to-digest substances are partially broken down into simpler components that are more readily available for absorption.

In short, soaking nuts makes them more nutritious!

Miller's is now offering Raw Hawaiian Macadamia Nuts

We have a direct connection with Ohana Farms, on the big island of Hawaii. They absolutely share our values. The use organic and regenerative farming practices and have an extreme attention to detail. They carefully dehydrate the nuts low and slow to preserve all of the nutrition.

We'll offer raw Hawaiian macadamia nuts for a limited time. If you love them and order them regularly (which I hope you do), we'll keep them around. So, if you're interested, add some to your next order now!

Mmmm... nothing beats the earthy flavor and crunch of a nut.

Our bone broth tested A+++ for heavy metals 🥳 NATURAL AND CLEAN

*Originally published on 3/14/25. Updated on 4/15/25. 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 body. Depending on the metal, it can accumulate in the bones, muscle, skin, brain, etc. 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 use apple cider vinegar to draw everything out and make it thick and gelatinous and nutrient rich (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. And, as we know, our poor planet is becoming more and more contaminated with toxins like these toxic heavy metals ðŸ˜¢ What I glean from this study is that we need more research. We need to stay vigilant and test from time to time. 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 actually tested twice. As it turns out, the first test results from March had a LOQ (limit of quantification) that was to high. So, we sent new products in April for testing at a lower LOQ. The results are in! Our bone broth tested A+++ for arsenic, cadmium, lead, and mercury. You can find the actual Eurofins test results right here! For easy reference, here's a chart summarizing the results: You'll notice that, for every sample, the results are "<2.0 μg/kg" and "<4.0 μg/kg".  The "<" indicates the limit of quantification (LOQ), the lowest concentration that can be accurately tested using the test procedure in that sample type. So if a "<" result appears, it means that none of that metal was found in the sample above the specific reporting LOQ. Whether or not they were present below this LOQ is information that's not provided by the test. It's also important to note that a Î¼g/kg is a part per billion (ppb). So, for 1 μg/kg, in every billion grams of that food, there would be one gram (or 0.0000001%) of that particular heavy metal. The small numbers matter when it comes to toxic heavy metals, since it doesn't take all that much for your body to become inundated and start experiencing issues or damage. These results are excellent. It means the broth definitely isn't overloaded with toxic heavy metals and are within safe levels.  Our amazing customers mentioned Mike Adams to me numerous times after we released the first set of broth results. Mike Adams is an outspoken consumer health advocate, investigative journalist, activist, and science lab director. It turns out Eurofins, the lab we used, is a lab that he recommends.  Moreover, our results land us in his highest rating when it comes to heavy metals! I think we're doing pretty great when it comes to providing clean, natural food. But, one result did make me pause. You might be thinking what I first thought -- "But wait, you got a reading above 4.0 μg/kg for arsenic. Isn't that bad?"  Let's dive in -- What's up with arsenic? First off, it's important to note that there are organic forms of arsenic as well as inorganic forms. Our body can handle the organic kind pretty well. But, the inorganic kind is carcinogenic. Our test results show the level of all arsenic, and it doesn't divide inorganic and organic. Second, as you can see from the Health Ranger rating above, your body can tolerate way more arsenic than the other three toxic heavy metals. It can handle 6x more than cadmium, 25x more than lead, and 103x more than mercury.  Third, it was a mystery to me how arsenic had a reading in the ground beef but not the beef bone broth. Thankfully, that has a pretty easy explanation. Whereas lead mainly accumulates in the bones, arsenic accumulates more in the organs and muscles. And, of course, meat is muscle. And finally, it was also quite perplexing how arsenic showed in our beef as well as our chicken. You see, our beef and chicken are grown on two separate farms (hours apart) and are processed at two separate processors (also hours apart). They're fed two completely separate diets, too! My only explanation is farmland in general or maybe even our environment in general.  Organic arsenic has always been naturally present in the soil and water. It's just there in small amounts. But, levels nowadays are likely higher due to overuse of products laden with inorganic arsenic over time. Starting in the 1940s, conventional farmers would include drugs filled with inorganic arsenic in the feed for pigs and chickens and turkeys to encourage fast growth and prevent disease. Ugh. This actually led to concerns about arsenic poisoning, and that that practice was banned recently, in 2016. It makes me think that all the agri-waste has contaminated our farmland a bit, perhaps in both the soil and water. And then of course there are synthetic pesticides and herbicides and fertilizers that may contain inorganic arsenic. And their use on conventional farms might runoff everywhere else. Since our meats are grown on farms that have been naturally managed for some time, I think that's why our arsenic levels were so low, especially compared to conventional meat.  Now, let's compare our results to food in general. Ours are extremely low. The data below is based on a few scientific studies: Arsenic: Rice contains anywhere from 90-450 ppb (that includes that rice cereal for babies, too). Meat and poultry in general typically contain 100-200 ppb. The max ours has is 6.8 ppb.Cadmium: Spinach contains 117-222 ppb. Rice contains 6-19 ppb. Meat and poultry in general contain about 10 ppb. Our has less than 2 ppb.Lead: Meat and poultry in general contain about 25 ppb. Our has less than 4 ppb.Mercury: The larger the fish, the more time it has to accumulate mercury. Swordfish and king mackerel can have about 1,000 ppb. Meat and poultry in general contain about 10-50 ppb. Ours has less than 2ppb. Wow! Putting that into perspective, it looks like our broth and meat are quite clean and extremely low in toxic heavy metals! Are you satisfied with our heavy metal results? Do you think we should take further action? Should we test other products?  Do you worry about toxic metals (or other junk) in your food? Where have your fears stemmed from?

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?
