You've probably heard people talk about raw milk being "more nutritious" than pasteurized milk.

But what does that actually mean? What's in raw milk that makes it different? And why does it matter for your health?

If you're considering making the switch to raw milk, understanding what you're getting (and what pasteurization destroys) is important.

Here are the 3 big components that make raw milk uniquely nourishing and what happens when you heat them away.

1. Living Enzymes That Help You Digest

Raw milk contains naturally occurring enzymes. Enzymes are proteins that facilitate chemical reactions in your body. The main digestive enzymes in raw milk include proteases, lipase, and phosphatase.

What These Enzymes Do

  • Proteases help break down milk proteins, making them easier to digest and absorb. This is especially important for people who struggle with dairy digestion.
  • Lipase aids in fat digestion, helping your body break down and utilize the cream and butterfat in milk more efficiently.
  • Phosphatase plays a crucial role in helping your body absorb calcium and other minerals from the milk.

Why This Matters

These enzymes make milk "self-digesting." Your body doesn't have to work as hard to break down and absorb the nutrients, because the milk is helping do the work itself. The enzymes essentially pre-digest components of the milk, making it easier on your digestive system.

What Pasteurization Does

Heat destroys these enzymes completely. In fact, the absence of phosphatase is actually used as a test to confirm milk has been properly pasteurized, because this enzyme is one of the most heat-resistant.

Pasteurized milk has zero active enzymes left. Your digestive system has to do all the work on its own, without any help from the milk itself.

This is one reason why many people who struggle with pasteurized milk have no problems with raw milk. The enzymes are still alive and actively helping with digestion.

2. Beneficial Bacteria and Probiotics

Raw milk isn't sterile... and that's actually a good thing.

It contains beneficial bacteria and natural probiotics that support gut health, immune function, and overall digestion. When milk comes from healthy, grass-fed cows raised on clean pastures with proper handling and safety protocols, these bacteria are beneficial (not harmful).

What Beneficial Bacteria Do

  • Support your gut microbiome - The good bacteria in raw milk help maintain the balance of microorganisms in your digestive system, which is foundational to immune health.
  • Crowd out harmful bacteria - Beneficial bacteria compete with and suppress potentially harmful bacteria, creating a healthier overall environment.
  • Aid in nutrient absorption - These bacteria help your body extract and absorb nutrients more effectively from the food you eat.
  • Produce additional vitamins - Beneficial bacteria can produce vitamins like B12 and K2 right in your digestive system.
  • Can jumpstart your body into producing the lactase enzyme - Lactase is the enzyme needed to digest lactose, milk sugar. And this is why some people who are lactose-intolerant (produce zero or not enough lactase) can handle raw milk but not pasteurized.

The Living Food Difference

Raw milk from healthy, grass-fed cows on clean pastures contains the good bacteria your body needs. It's a living and probiotic food, similar to yogurt, kefir, sauerkraut, or kombucha.

What Pasteurization Does

Heat kills ALL bacteria, both good and bad. Pasteurized milk is essentially "dead" milk, sterile, lifeless, with nothing left to support your gut microbiome.

The very bacteria that make raw milk a living, probiotic food are completely destroyed by the pasteurization process.

This is why raw milk supports gut health and immunity in ways pasteurized milk simply cannot. The beneficial bacteria that could help your digestive system are no longer present.

3. Heat-Sensitive Vitamins and Minerals

Raw milk is naturally rich in vitamins and minerals: B vitamins (B2, B12), vitamin C, vitamin A, vitamin D, calcium, magnesium, zinc, and more.

But here's the problem: many of these nutrients are heat-sensitive. They don't survive the pasteurization process intact.

What Pasteurization Does to Nutrients

  • Vitamin C is significantly reduced or completely destroyed by heat.
  • B vitamins (especially B6 and B12) are partially degraded during pasteurization.
  • Folate levels drop when milk is heated.
  • Vitamin A and Vitamin D can be damaged or altered by heat processing.
  • Mineral absorption becomes more difficult. While the minerals themselves (like calcium and magnesium) remain in pasteurized milk, your body can't absorb and use them as effectively without the living enzymes and beneficial bacteria that facilitate mineral absorption.

The Bioavailability Factor

Pasteurized milk might still contain some vitamins. They're often added back artificially after processing to replace what was lost. But your body can't absorb and use synthetic vitamins as effectively as naturally occurring ones.

And without the living enzymes and bacteria, even the vitamins that survive pasteurization are harder for your body to access and utilize.

Raw milk delivers vitamins and minerals in their natural, bioavailable form. It's the way your body recognizes and uses them best. Everything works together synergistically: the enzymes help break down nutrients, the bacteria aid absorption, and the vitamins remain in their intact, natural state.

The Bottom Line: Raw Milk Is Alive

Here's the fundamental difference:

Pasteurized milk is dead milk.

The heat process kills the enzymes, destroys the beneficial bacteria, and degrades heat-sensitive vitamins. What's left is nutritionally inferior. It's harder to digest, less bioavailable, and stripped of the living components that make milk truly nourishing.

Raw milk from healthy, grass-fed cows is alive:

  • Living enzymes that help you digest proteins, fats, and minerals.
  • Beneficial bacteria that support your gut microbiome and immune system.
  • Vitamins and minerals in their natural, bioavailable form that your body can actually use.

This is why people choose raw milk: for maximum nutrition and digestibility.

Not All Raw Milk Is Created Equal

It's important to note that the quality and safety of raw milk depends entirely on how it's produced.

Raw milk from sick cows in unsanitary conditions is NOT safe. Raw milk from confinement dairies with poor handling practices is not the same as raw milk from healthy, grass-fed cows on well-managed pastures.

Quality matters... a lot.

Our Raw A2A2 Milk Standards

Our raw milk comes from 100% grass-fed A2A2 cows on regenerative pastures. Here's what makes it different:

Never heated or pasteurized - All enzymes, bacteria, and nutrients remain intact and alive.

Rapid cooling to 34°F - Milk is cooled immediately after milking to preserve freshness and safety.

Monthly lab testing - We test every month to ensure safety and quality.

Gold Standard safety protocols - Strict cleanliness, organic cleaning products, 160°F hot water sanitation, proper equipment maintenance.

Time limits - Milk is never held longer than 3 days in the bulk tank to ensure maximum freshness.

A2A2 genetic testing - All our dairy cows are tested to ensure they produce only A2 beta-casein protein, which is easier to digest for most people.

100% grass-fed - Cows graze fresh pasture during growing season and eat hay in winter. Never grain, never confined.

Fresh within days - From the cow to your refrigerator within days, not weeks.

This is milk the way nature intended. Alive, nourishing, and safe.

Who Should Choose Raw Milk?

Raw milk is ideal for people who:

  • Want maximum nutrition and digestibility from their dairy.
  • Struggle with pasteurized milk but want the benefits of dairy.
  • Care about eating living, probiotic foods.
  • Want to support regenerative agriculture and independent farms.
  • Prefer minimally processed, traditional foods.
  • Are looking for bioavailable nutrients in their natural form.

A Note on Digestibility

Many people who can't tolerate pasteurized milk have zero issues with raw milk. This is likely because:

  • The living enzymes (especially proteases) help break down milk proteins.
  • Beneficial bacteria aid digestion.
  • Beneficial bacteria can jumpstart your body into producing lactase.
  • The A2 protein is naturally easier to digest than A1 protein.
  • The milk is in its natural, unaltered state.

If you've struggled with dairy before, raw milk from grass-fed A2A2 cows might be worth trying.

The Choice Is Yours

Why does our farm direct food cost more? Here are 5 big reasons why.

We're not going to pretend our food is cheap. When you compare our prices to conventional grocery store meat and dairy (even the organic kind), there's a clear difference. And we know that matters, especially when you're trying to feed a family on a budget. But here's the thing: the price gap exists for very specific reasons. We wanted to be completely transparent about what you're actually paying for when you choose Prairie Foods. Because it's not just food. It's a completely different system. 1. We Don't Get Government Subsidies Conventional agriculture is heavily subsidized by the government. Corn, soy, and grain crops get billions in subsidies every year, which keeps the price of conventional feed (and therefore conventional dairy and meat) artificially low. Our plain farmers don't get those subsidies. We raise animals on 100% grass and pasture without any subsidized grain. That means we pay the real cost of farming. No government checks to offset expenses. You're paying what food actually costs to produce the right way. 2. Regenerative, Pasture-Based Farming Is Labor-Intensive Moving cattle and rotating chickens to fresh pasture daily during the growing season. Moving pig fencing often so they have new un-muddied land to make muddy. Managing complex pasture rotations to build soil health. This takes time. A lot of it. Factory farms cram thousands of animals in confinement and automate everything. It's efficient, but it's also why those animals never see sunlight, stand in their own waste, and need constant drugs to stay alive. Our way is slower, harder, and requires more hands-on work. Our plain farmers are out there every day. They're moving animals, checking pastures, managing soil health, and ensuring every animal has fresh grass and clean water. That labor is built into the price. You're paying for farming that heals the land instead of destroying it. 3. We Have Extremely High Standards Most farms do the bare minimum required by regulations. We do significantly more. For raw dairy: Monthly lab testing (not just the required minimum)Gold Standard safety protocolsTemperature control to 34°F immediately after milkingStrict timeline limits (milk held no longer than 3 days)Organic cleaning products and 160°F hot water sanitationA2A2 genetic testing on all dairy cows For meat processing: Small-batch processing with more care and attentionWashed only with water (no chemical washes)In house butchering that prioritizes quality over speed These standards cost more to maintain. But they're why you can trust our food completely. You're paying for safety and quality that go far beyond legal requirements. 4. We Pay Our Farmers Fairly Factory farms squeeze farmers on contracts that barely let them survive. Many contract farmers are essentially trapped, doing all the work while corporations keep most of the profit. We don't operate that way. Our plain farmers are independent. They help set their prices, make their own decisions, and keep fair profits from their work. They're not beholden to corporate contracts or being squeezed to the breaking point. When you buy from Prairie Foods, farmers actually make a living. Fair pay for farmers means they can continue doing this work for the long term --- raising animals right, building soil health, and providing clean food for families like yours. You're paying for a food system that respects the people who grow your food. 5. Free Shipping Is Built Into Product Prices Most online food stores charge separate shipping fees. They're often $20-50+ per order, which can be shocking at checkout. We handle it differently. We roll most of the delivery cost into our product prices so we can offer free delivery over certain order amounts. This makes budgeting easier (no surprise fees at checkout) and rewards customers who stock up. Yes, this means our prices may look higher. But when you factor in free delivery, the total cost is often competitive... and way more transparent. You're paying for convenience and honest pricing with no hidden fees. The Bottom Line Our food costs more because: We're not subsidized by the governmentRegenerative farming requires more laborOur standards are significantly higher than requiredWe pay farmers fairlyDelivery is included in the price We're not trying to compete with factory farm prices (even the organic ones). We can't. And honestly, we don't want to. Factory farming only looks cheap because the real costs are hidden: environmental destruction, animal suffering, depleted nutrition, farmer exploitation, and long-term health consequences. Our prices reflect the true cost of doing things right. Is It Worth It? Only you can answer that for your family. But here's what our customers often tell us: "We spend more on food now, but we spend way less at the doctor." "I'd rather invest in real food than pay for it later with my health." "When I think about what I'm actually getting - clean food, healthy soil, fair pay for farmers - it's worth every penny." We're not asking you to justify the expense to anyone else. We're just asking you to understand what you're actually paying for. Real food from independent regenerative farms. Raised right. Every time. Questions about pricing or products? Contact us. We're here 🙂 ----- P.S. If budget is a concern, you might consider switching out one grocery store item and/or focusing on our most affordable cuts: ground beef, whole chickens, larger bulk purchases. You can still eat clean, regenerative food without breaking the bank.
