At Miller's Bio Farm, our commitment to health and wellness drives us to delve deeply into the intricacies of every ingredient and nutrient. We value the trust our customers place in us and continuously strive to stay ahead of emerging health topics. Recently, our curiosity led us to explore the world of PUFAs. After all, many of our customers SHOP WITH MILLER'S because they're seeking low or virtually no PUFA diets.

We wanted to understand: What exactly are PUFAs? Why have they garnered attention in the health community? And most crucially, how might they affect our overall well-being?

What are 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. PUFAs are further classified into two main types: omega-3 and omega-6 fatty acids. 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.

Who is Dr. Ray Peat and What Did He Discover about PUFAs?

Enter Dr. Ray Peat, a brilliant scientist and researcher who has dedicated a significant portion of his career to understanding the effects of various nutrients on our health. According to Dr. Peat, PUFAs, when consumed in excess, can have a multitude of negative effects on our health. One of his primary concerns about high PUFA intake relates to their instability when exposed to heat, light, and oxygen, leading them to oxidize easily. When consumed, these oxidized fats can cause oxidative stress and inflammation in the body, potentially contributing to various diseases.

Moreover, Dr. Peat found that excessive PUFA intake could suppress the thyroid function, slowing down our metabolism and potentially leading to various health issues like decreased energy, weight gain, and more.

The PUFA Problem: Why is it Harmful?

The problems with PUFAs, as pointed out by Dr. Ray Peat and validated by various studies, include:

  1. Inflammation: PUFAs can lead to an increased production of pro-inflammatory molecules, thus promoting inflammation in the body.
  2. Oxidative Stress: Given their instability, PUFAs easily undergo oxidation, producing harmful compounds that can damage cells and DNA.
  3. Thyroid Suppression: High PUFA intake can interfere with thyroid function, which plays a crucial role in metabolism, energy production, and overall health.
  4. Potential Link to Diseases: Excessive PUFA consumption might be linked to a higher risk of various diseases, including heart diseases, certain cancers, and more.

The PUFA Connection: Implications for Disease Progression and Autoimmune Conditions

The potential links between high PUFA intake and various health concerns raise pressing questions about the long-term consequences of our dietary choices. Particularly, does a diet abundant in PUFAs amplify the risk for certain diseases or even exacerbate autoimmune conditions?

Autoimmune Conditions and PUFAs: Autoimmune diseases arise when our immune system mistakenly attacks healthy cells in our body. Factors contributing to these conditions are multifaceted and include genetics, environmental triggers, and possibly diet. Some studies suggest that a higher intake of omega-6 PUFAs can enhance inflammation, which plays a significant role in many autoimmune diseases. By potentially amplifying inflammatory responses, a high PUFA diet may exacerbate symptoms in individuals predisposed to or already diagnosed with autoimmune conditions.

PUFA and Disease Magnification: Beyond autoimmune conditions, a diet consistently high in PUFAs may accentuate risks for other diseases. As PUFAs can promote inflammation and oxidative stress, two pivotal factors in the development of many chronic diseases, individuals regularly consuming high amounts of these fats may find themselves at an elevated risk. This includes but isn't limited to heart diseases and certain types of cancers.

Understanding PUFA-free Foods:

When we say a food is "PUFA-free", we're indicating that it contains negligible or no polyunsaturated fatty acids. Remember, fats in foods are usually a combination of different types of fatty acids: saturated (SFAs), monounsaturated (MUFAs), and polyunsaturated (PUFAs). No natural food is entirely devoid of a particular type of fat, but some foods have such minuscule amounts of PUFAs that they can be effectively considered "PUFA-free" for dietary purposes.

Why Seek PUFA-free Foods?

There's a growing interest in PUFA-free or low-PUFA diets due to concerns about the potential negative health implications of consuming excessive PUFAs. As previously mentioned, excessive PUFA consumption may contribute to inflammation, oxidative stress, and other health issues. Additionally, many PUFAs, especially those in processed vegetable oils, can be easily oxidized, forming harmful compounds when exposed to heat, light, or air.

Examples of Foods that are Virtually PUFA-free:

At Miller's Bio Farm, we pride ourselves on the quality of our products, emphasizing the nutritional content and health benefits they offer. Virtually all our foods stand out as being low in PUFAs or virtually PUFA-free. This nutritional advantage stems from our farming practices: our ruminant animals are 100% grass-fed, while our non-ruminant animals are strictly reared without corn and soy in their diets. This ensures that the products we offer are not just delicious but also nutritionally aligned with holistic health goals.

Examples of Foods that are Virtually PUFA-free:

1. Animal Fats: LARD, TALLOW, BUTTER, and GHEE are primarily made up of saturated and monounsaturated fats, with only trace amounts of PUFAs.

2. Tropical Oils: Coconut oil and palm oil are predominantly saturated fats and contain very low levels of PUFAs.

3. Certain Dairy Products: Full-fat dairy products, especially from grass-fed animals, tend to have higher saturated fat content and lower PUFA levels. At Miller's Bio Farm, our COW DAIRY, RAW COW DAIRY, and RAW BUFFALO DAIRY products are virtually PUFA-free, while our RAW GOAT DAIRY is categorized as low PUFA.

4. Certain Meats: Fatty cuts of beef, lamb, and pork, especially from animals raised on natural diets, will generally have lower PUFA content compared to poultry or grain-fed livestock. In line with this, our 100% GRASS FED BEEF offerings at Miller's Bio Farm are virtually PUFA-free. Additionally, our corn and soy free PASTURED CHICKEN, PASTURED TURKEY, and WOODLAND PORK selections, known for their superior quality, are all low in PUFAs.

5. Eggs: Another essential mention is eggs. The CORN & SOY FREE EGGS at Miller's Bio Farm are meticulously sourced and are considered low PUFA, making them an excellent choice for those keen on monitoring their PUFA intake.

A Word of Caution:

While there's merit in being cautious about excessive PUFA consumption, it's also essential not to swing to the other extreme and completely eliminate all sources of PUFAs from your diet. Omega-3 and omega-6 fatty acids, which are types of PUFAs, are essential for the body, meaning we need to get them from our diet because our body cannot produce them on its own. The key is achieving a balance and avoiding sources of oxidized or processed PUFAs.

The Bottom Line:

In the ever-evolving landscape of nutrition, it's crucial to navigate our choices with information that prioritizes our well-being. Aiming for PUFA-free or low-PUFA foods isn't merely a trend; it's a conscious decision to prioritize the quality and integrity of the fats we introduce into our bodies. By doing so, we move closer to a dietary approach that aligns with nature – favoring fats that are less processed, less prone to oxidation, and thereby more stable and beneficial for our health.

Such an approach underscores our belief at Miller's Bio Farm: that food, in its most natural state, is often the best. While PUFAs have their place and role in nutrition, it's important to strike a balance. Overconsumption, especially of oxidized or excessively processed PUFAs, can pave the way for health concerns. By being aware and making informed choices, we can relish the myriad benefits of healthy fats without the pitfalls of excessive PUFA intake.

In conclusion, our journey through understanding PUFAs reminds us of the importance of ongoing education, reflection, and making choices that resonate with holistic health. As always, we remain committed to delivering the best to our community and continuing the conversation on vital health topics.

If animals eat wheat, does the gluten transfer to the eggs and meat?

If animals eat wheat, does the gluten transfer to the eggs and meat?

We've been getting this question a good amount lately --- If your chickens and pigs eat wheat, which contains gluten, then do your eggs, chicken, and pork contain gluten, too? Super interesting question. I mean, the saying "you are what you eat" holds true to some extent. But... digestion is the opposite of simple. The short answer is --- Gluten in animal feed does NOT transfer to eggs or meat. Eggs are meat are naturally gluten-free. You see, just like you, when an animal eats gluten, the gluten is broken down into amino acids during digestion. Then, those amino acids are reassembled into a variety of things that support life and growth - proteins, hormones, neurotransmitters, etc. We have anecdotal evidence, too. There are many Miller's customers with Celiac disease or gluten sensitivities that handle our eggs, chicken, and pork without any issues. In fact, some say that our eggs and meat are the only they can tolerate - wow! A little caveat --- cross contamination. Here are two scenarios: What if a butcher uses products on meat or surfaces that contain gluten? I mean the list of approved sanitizers is loooong. This isn't a worry with our foods. Our eggs and chicken only ever touch water. And our pork is washed in organic apple cider vinegar.Can gluten be added to foods like sausages or pies or lunchmeat? Yes. Some baking sodas and spice blends contain gluten. And some trace ingredients (that don't need to be on the label) like maltodextrin or modified food starch may contain gluten. This isn't a worry with our foods. We try to keep things as pure as possible. Intolerances and sensitivities can be complicated. Some people react to parts of gluten, not the whole molecule. During digestion, gluten is broken down into peptides in your intestinal tract. Then, those peptides are broken down into amino acids. Amino acids are the building blocks of life. They're reassembled (with other things like broken down vitamins and minerals) into important stuff that your body needs - proteins, tissue, enzymes, hormones. People with confusing (and sometimes inconsistent) reactions might be having a reaction to a specific peptide or part of a molecule. It might now be the whole molecule that's giving you trouble! That's why many people with gluten sensitivity do fine with sourdough and/or einkorn (in fact, we even have a customer with Celiac disease that loves our sourdough einkorn crackers). Sourdough partially digests the gluten for you and possibly changes the way your body breaks it down. And einkorn is a heritage grain that contains a completely different kind of gluten compared to conventional wheat - gluten AA. There's actually a certain test you can take to give you more info. It's called a Zoomer test. Instead of simply seeing if you're reacting to a whole protein, it sees how your body responds to individual peptides. Neat! Or maybe people aren't reacting to wheat itself. Rather, they're reacting to chemicals sprayed on wheat. Many people with gluten sensitivity go to Europe and eat all the bread. Why is this? Well, maybe it's because glyphosate is banned in Europe. But here in the US, we're still spraying it on conventional wheat to dry it out quickly and get it ready for harvest. It could be that some people are reacting to a chemical on wheat... not the wheat itself. I mean, glyphosate is known for disrupting the gut! This could explain why some people don't do well with some eggs and meat but do just fine with ours. After all, we have the highest natural standards and aim to give you the purest food possible, down to the nitty gritty. What have you experienced? Are you sensitive or allergic to gluten but can handle eggs and meat? How do our eggs and meat feel for you? I'd love to hear from you.

Ugh greenwashed labels. What does it take to get ___ on a label anyway?

Ugh greenwashed labels. What does it take to get ___ on a label anyway?

Not a fan of the confusing, greenwashed labels in store? Yea, me too! And it's especially real for me, because I'm responsible for getting our labels approved with the "powers that be". Here's a little story with a big inside scoop... I made new labels for our bone broth a little while ago. It didn't go as smoothly as planned. Why? I put the little icons about our farming practices on them. They look like this: Yup, despite being 100% accurate and true, they were denied!! We're not allowed to put those statements on our food labels. So, I asked the USDA guy, "What would it take to get those claims on the labels, anyway?" The answer was kinda shocking. First off, there's some guidance on wording. Silly technicalities in my opinion. For example, you can't use the term "No Spray" but you can say "Produced without the use of synthetic pesticides." Or another example is that you can't say "No Routine Antibiotics or Vaccines" but you can say "Raised without routine use of antibiotics or vaccines."  Second, the processor needs to update their documents to provide traceability. In other words, they need to document how they make sure the bones for our bone broth don't get mixed up with bones from other farms. I mean, this is pretty simple, especially with small batch foods like ours. But the documentation needs to be meticulous. Drafting it in government-approved language can be time consuming and/or costly. And lastly, once you get the wording and process right, you need proof. This was the real shocker for me: Want to know what proof would suffice for all the claims above? A 2-3 sentence affidavit (AKA a super short letter) signed by all farmers that supply us. That's it!? This lead me to a bunch of questions: What if a company submits a letter from one farmer but actually has other farmers that supply them, too? What if a company changes farmers? Will they submit new letters?What if a company's farmers change their practices in the future? Will they immediately update their labels?Are the "powers that be" checking on this? Is anyone checking on this?Is this why most farms and food facilities don't allow outside people coming in? It seems to me that, if a business isn't doing what the label says, the only way to find out is via a whistleblower. And the only way to make them stop is to take them to court. You know, like what's happening with Vital Farms and their pasture raised egg claim right now. It seems to me that, all that good natural stuff on labels - grass fed, pasture raised, antibiotic free, etc - doesn't mean it's true. Certifications are a little better, but the same kinda thing can be said about those, too. This is why, at Miller's, we choose to NOT sell in stores.  No wholesale for us. In fact, we don't even have an on farm store. We only sell directly to our customers via our website.  And, we choose to only get certified for what's required. This way, we can make our own natural standards. And, we can provide you will all the info and proof you need. Descriptions, photos, blog posts, test results, and more. So, what do you think? Should we do the affidavit thing to get claims on our bone broth labels? What proof do you need to feel confident in your food choices? I'd love to hear from you.
