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.

Does the A2 thing or raw milk thing matter more? It depends.

What's up with soooo many people not being able to tolerate dairy these days? Could it be how conventional milk is being altered? Sure, switching to conventional "certified organic" milk that you can find in nearly any supermarket might help. You're eliminating some of the modern milk alterations. With organic, you're getting rid of the antibiotics. Antibiotics are routinely given to conventional cows to help keep them disease-free, even when in unsanitary or unnatural living environments (like indoors on concrete all the time). With organic, you're getting rid of hormones, which are given to conventional cows to make them produce more milk. More milk + the same amount of feed = more profit.With organic, you're removing some weird, unnatural stuff in the feed. This includes GMO fragments that might make their way into the milk as well as the awful chemicals like glyphosate used to grow GMO crops. But, keep in mind that "organic" does NOT mean chemical free. It simply means that any chemicals used are "approved for organic". Switching to organic is a great step in the right direction. But... what if you already did that and are still experiencing dairy issues? There are so many symptoms of dairy allergies or intolerances. They range from bloating to tummy troubles to nausea to brain fog. In this scenario, it's most likely one of two things, the lactose or the casein protein. There's a different solution for each: Lactose Intolerance β†’ Can be solved with raw or cultured dairy Some people are "born to dance", some are "born to lead", and some are "born to rock"... but all humans are born to drink milk! I mean, breast milk is our first food after all! Babies are naturally designed to digest lactose (milk sugar). That means that, as a baby, you naturally produce tons and tons of lactase, the enzyme required to digest lactose, in your gut. But, over time, a human naturally produces less and less lactase. This is especially true if a human stops eating dairy or foods with the living microbiology present in raw dairy like lactic acid bacteria. After all, why would your body continue producing something if it's useless? Here's the good news. It can be reversed! You may be able to produce lactase again, you may be able to drink milk again, and may be able to eat cheese again. At least, this is true for many, many people. The living dairy microbiology in raw and fermented dairy (even yogurt or kefir made from pasteurized milk as long as it has live cultures in it) can jumpstart your body into producing more and more lactase. Pretty neat! A1 Protein Intolerance β†’ Can be solved with A2/A2 dairy The A1 beta-casein protein is relatively new. A few thousand years ago, humans made cows in Europe pretty stressed. They moved them indoors in cities and started feeding them grain (the byproduct of making whisky and other stuff). And what do organisms tend to do under stress? Mutate! Unlike any other mammal, those European cows had a genetic mutation that makes them produce a new type of protein - the A1 beta-casein protein. Those cows made their way to the US. And now, basically all American milk has a mix of A1 and A2 beta casein proteins. Some people, especially those from eastern countries like India (where cows didn't mutate) or who drink pasteurized or boiled milk, might have an issue with A1 but can handle the A2 beta-casein protein just fine. Switching to A2/A2 milk is all they need to handle dairy again. It's important to note that the only way to know what kind of milk a cow produces is via a genetic test. We test all of our cows, and that's how we're sure our milk contains 100% A2 beta-casein protein. It's A2/A2! Do you have issues with dairy? Did raw or A2/A2 help? What solved your problem, or are you still looking for a solution?  I'd love to hear from you.

100% grass fed and finished beef different from grain fed beef? Yes, it is!

Why grass fed beef? And, I'm not talking about that silly "grass fed" label in the supermarket, which doesn't necessarily mean what you think (read more on that here). I'm talking about truly pastured, 100% grass fed and finished beef. Feeding beef cattle 100% grass is the most natural way. Beef cattle are ruminants. That means they have 4 stomachs are are designed to graze and eat and digest plants... not fully grown seeds like corn and soy and canola or their oils. Eating 100% grass, ideally fresh from the pasture, is how cattle stay in their best health. When beef are fed grain, it creates a lot of acid in their stomach, lowering the pH. It creates an imbalance in gut microbiology, which can result in some pretty awful health outcomes for the cow (sometimes even death).  And of course, the healthier the animal, the healthier and more nutrient-dense the food it produces. 100% grass fed and finished beef is more nutritious than grain fed beef! Compared to conventional grain-fed beef, 100% grass fed and finished beef has: 3x more Vitamin E2.5x more Vitamin C2-3x more B Vitamins9x more Vitamin B310x more EPA3x more DHA10x more linolenic acid (alpha/gamma)2-4x more Conjugated Linoleic Acid (CLA) And, grass fed beef has a much better omega 6/3 ratio, usually less than 3:1. Compare that to conventional beef, which has a ratio more than a 15:1. Wow! For some reference, humans should be eating a 4:1 omega 6/3 ratio for optimal health. But, the conventional American diet typically provides a 20:1 ratio. Ugh, no wonder Americans are so sick! Truly pastured, grass fed beef is more flavorful and has a better bite compared to conventional beef. When beef cattle aren't fed a bland diet of corn and soy and instead eat biodiverse, regenerately managed pasture, the meat has more flavor. When beef cattle have plenty of room to roam and exercise those muscles, the meat has texture to it. It has a bite.  When some people start eating grass fed beef, they're sometimes put off by the flavor and texture. They might describe it as gamey and tough. But, now that I've been eating grass fed beef for years, it's quite the opposite. Conventional beef is tasteless and boring and mushy. Do you choose grass fed and finished beef? Why? Is it because it's more humane, more nutritious, better tasting, or a combo of them all? I'd love to hear from you.

Food web vs food chain. I'll use the crazy egg recall as an example.

At Miller's, we're building a food web. This is a lot different than the modern food chain most Americans rely on. A food chain is a factory-filled engine.  Here are the links that usually make up the food chain. Mega feed mills and fertilizer plants --> mega factory farms --> mega processing plants --> mega distributors --> mega supermarkets. And in between all of those things are mega supplies and transportation companies.  When one link breaks, the whole chain goes down! Sure, it's made food more affordable. But, it's also made our food system fragile. Let's use the egg recall that's happening right now as an example. It's a conventional egg recall (NOT our eggs, which we have plenty of btw). The current salmonella outbreak has sickened at least 89 people to date. It's affected 1.7 million cartons of eggs in 9 states, starting in March. Hundreds of thousands of people have eaten contaminated eggs. Wow, I mean, that's awful on such a big scale. But, here's what's interesting to me - there are 29 different products affected. How could that be? How could they be related? Well, those products come from 10 different egg brands who all have their eggs packed at 2 facilities. Talk about mega ag! Now, I don't know this for sure, but I would bet that all of those millions of eggs come from one mega-farm that has a salmonella outbreak inside one of its mega buildings. Keep in mind that a CAFO (confined animal feeding operation) is defined as having a minimum of 82,000 laying hens. In other words, it's plausible for those millions of eggs to come from one "farm". And the saddest part? All of those hens were likely culled to stop the outbreak quickly. One last note here -- the egg recall example is actually a small one. It's even worse with beef. Did you know that 85% of all grain finished beef is processed by just 4 companies? Geez! And, I mean, we all saw the food chain break during COVID.  On the flip side (and gosh, I'm happy there's an alternative), a food web is a collection of small feed suppliers, farmers, processors, etc.  They are all independent, and each has an important role in getting your food to you. When one intersection in the web breaks, it's fairly easy to repair it and find someone else to fill in. It's a resilient way to produce food. The downside to a food web is that the food does cost more. Let's take our egg farmers as an example. They work in small "pods". They all get their feed and cartons from the same place. They all follow the same farming practices. But, other than that, they work independently in "pods". Right now, we have 2 egg pods. A "pod" consists of 1-5 family farmers with small flocks (no more than 3,000 birds each). And that group of farmers has their eggs packed at one small family egg packer. If we need more eggs, then we need to start another pod. If one pod (or a part of a pod) goes down, another can likely fill in.  What do you think? Is it worth it to pay more for food from a resilient food web? Do we need the food chain to supply affordable food? What does our food future look like? I'd love to hear from you.
