Paleo & Calcium

Many of us have been there. Those who choose to limit dairy as part of their Paleo-style eating plan are asked by terribly concerned family and friends:

“But how will you get your CALCIUM?”

They’re convinced – nay, indoctrinated – by the credo that is the USDA’s MyPlate (I won’t even link it, it’s so ridiculous), which implies – with its endorsement of low-fat dairy – that such a processed “food group” is the only way to get calcium.

Well, it’s not.

Duh.

Leafy greens and homemade bone broth – one of my absolute favorite superfoods – are sources of calcium that are highly bio-available (easily absorbed and utilized by the body). I wouldn’t worry about somebody’s calcium status if they were eating lots of veggies and bone broths – they’re probably cultivating plenty of non-Westernized, healthy food habits above and beyond guzzling ultra-pasteurized skim milk between bites of Fiber One.

I’m being cheeky. But there are a few legitimate ways to address this question. Unfortunately, the old “acid-base balance” thing isn’t the answer.

(I must point out: I live “Paleo” with a good dose of “Weston A. Price” mixed in. See HERE for details. I don’t think all dairy is evil – and I have no hard-and-fast dairy “Manifesto,” – but I do think a responsible consumer of dairy products needs to be well-educated. See my All About Dairy posts at Steve’s Original: HereHere and Here.)

The Calcium Answer, Method One: The Awesome Answer.

My preferred answer to the question “But how will you get your CALCIUM?” is to simply say, “from your MOM!”
Unfortunately, that’s not always constructive.

The Calcium Answer, Method Two: The short, yet open-ended answer.

I like to address the calcium question with yet another question, such as: “Who told you that DAIRY is the only way to get CALCIUM?”

Often the answer is a bumbling “…uh, well, the food pyramid – er, plate? The government? Dr. Oz…Osteoporosis?” which opens the door to the diclofenac:

We eat Nature – not pasteurized, homogenized, de-fatted Products. Broth – a mineral-rich, traditional food, is a higher-quality source of calcium and minerals (and other great things, like collagen). Vegetables provide calcium too.

Whether you’re concerned about calcium intake or things like Osteoporosis, realize that it’s not about quantity anywayIt’s about giving your body the tools to use calcium efficiently and properly. We do this by getting the co-factors that MAINTAIN quality bone. Co-factors are everything from balanced blood sugar to other vitamins and minerals, fatty acids, and even exercise.

It’s ignorance of this fact that’s caused doctors and Big Pharma to have dairy-calcium tunnel vision. Incidentally, leafy greens are higher in calcium, calorie-for-calorie, than milk, and have none of the allergenic properties of standard, grocery store, corn-fed, factory-farmed, pasteurized, homogenized dairy. Bone broth is rich in other minerals, like magnesium; as well.

Okay, so that’s a bit of a mouthful. But it seems the ubiquitous “got milk?” campaign hasn’t really improved peoples’ overall bone health – judging by the ever-present advertisements for drugs that “fight osteoporosis.” Something’s not right.

We’re incredibly bone-centric when it comes to this issue – understandably so, since 99% of our calcium is stored in our skeletal system. But truly, it’s not about how much calcium we take in. It’s about balancing bodily systems with Real Food so that the body can maintain homeostasis, optimize nutrient absorption and utilization, and – of course – maintain excellent bone health.

With that…

The Calcium Answer, Method Three: The awesomely intricate, TRUE STORY about Calcium…

…and specifically, why someone on a Paleo-style plan – especially an optimized, “Paleo Plus” plan rich in bone broths and fat-soluble vitamins – simply doesn’t need to worry about their calcium status!

The most important thing to understand is this: the way your body uses calcium – including how your bones maintain density and quality – is entirely dependent on co-factors.

Here’s a rundown:

{Sidebar: Osteoblasts are bone-building cells. Osteoclasts are involved in the natural, revolving process of bone breakdown. Osteocytes are bone cells.}

Co-Factor 1: Hormonal Balance.

The body obsessively regulates both blood pH and blood sugar balance.

Buffering blood pH involves the alkalinizing properties of calcium. The parathyroid gland releases Parathyroid Hormone to regulate blood calcium (thereby buffering blood pH) by initiating osteoclastic activity. Calcitonin (released from the thyroid) counter-balances this process by inhibiting osteoclastic activity. Estrogen and progesterone “check-and-balance” one another when it comes to calcium as well.

(Another problem in modern life? Xenoestrogens. Estrogen-mimicking substances like soy and plastics that skew this balance.)

The body prioritizes blood sugar balance so highly because it profoundly affects your hormonal balance and signaling. If your blood sugar is out of control, nothing else will fall into place – including calcium balance. Elevated blood sugar, stress, and resulting cortisol disregulation and adrenal stress increases calcium mobilization from the bones – as in, they reduce bone density.

The parathyroid gland also signals the body to produce specific binding proteins for the minerals it needs – for example, calcium. (Yet another signaling loop that’s inhibited by a bad diet.) A good way to prove that the modern governmental dietary recommendations are a breeding ground for disregulated blood sugar is my side-by-side comparison of the glycemic load of two plans: the first, a Standard American “healthy” plan; the second, a sample “Paleo” plan. (And this plan doesn’t include bone broth – imagine how many minerals it would add!)

Co-factor 2: Hydration (Water & Electrolytes)

I won’t obsess over this, since we all know how important hydration is to health. Water, broth, and water-dense foods like whole proteins and vegetables are extremely hydrating. Soda, however, is not – it’s important to note that the orthophosphoric acid in soft drinks may cause bone breakdown, especially with high consumption over time. A balance of electrolytes is in the body is important. Himalayan or Celtic sea salt is a great addition to the diet, although adding excess refined salt to a Standard American Diet filled with packaged and processed foods is not recommended. (6)
Also – kick the Cola.

Co-factor 3: Don’t Take Counterproductive Drugs.

I’m not talking about the fun kind of drugs (although you should probably toss those as well). Big Pharma has created some truly gnarly “solutions” to osteoporosis ( like Boniva). These drugs literally inhibit osteoclastic activity. This means they keep bones from breaking down – and stop the natural, necessary and constant process of bone remodeling. OsteoBLASTIC activity without osteoCLASTIC activity means bones become more dense, but NOT stronger. In fact, Dr. Mercola calls these drugs “poison.” Sorry Sally.

Co-Factor 4: Digestion.

The body must have adequate HCL (Hydrochloric Acid) to absorb calcium. Modern acid blockers like Nexium and Prilosec literally stop the production of stomach acid, and because of this, nutrients can’t be absorbed properly. This wreaks havoc across all bodily systems, because they all require adequate nutrients to function properly. (In fact, you want MORE stomach acid, not less!)

Additionally, dietary factors – like the consumption of gluten and grains – can interfere with nutrient absorption in the gut. (See this post – USDA: Proud Sponsors of Nutrient Deficiency.) Specifically, the phytic acid in grains and beans can bind to minerals like calcium, magnesium and zinc, rendering them indigestible. (6) This becomes a marked problem in a Standard American Diet, which is dangerously rich in these “mineral binders.”

Co-factor 5: Other Minerals & Vitamins
Your ability to absorb and utilize minerals is absolutely mediated by the components of the foods you eat (see my USDA post for more on this).

Adequate intake of magnesium and Vitamin D are the co-factors you’ll hear about most often. But it’s not about hammering your body with one at the exclusion of another. Calcium, Magnesium and Vitamin D are not the Three Musketeers. They’re more like the Executive, the Legislative, and the Judiciary: they’re not always friends, but they keep one another in check. They even inhibit one another – but only when necessary.

Vitamin D works with Parathyroid Hormone to increase blood calcium. It also regulates the depositing of calcium in the proper areas to protect the body from improper calcification (like arterial calcification – also known asclogged arteries). If the body isn’t pulling adequate calcium from the diet, it’ll come from the bone.

Magnesium is involved in calcium transport, but it will also block calcium pathways as needed – acting as a counter (a “relaxer”) to calcium’s properties of contraction. Magnesium also helps convert Vitamin D to its active form, which allows for calcium absorption. (1)

I write at length about the extremely importantoften deficient VItamin K2 in my post “Why You Need Vitamin K2.” Check it out – Vitamin K2 is active in everything from bone synthesis and formation to fertility and skin health. You can supplement with it, you can choose grass-fed, full-fat dairy products like butter and ghee, or you can buy the ancestral food High-Vitamin Cod Liver Oil/Butter Oil Blend, which provides vitamins A, D and K2 in proper proporiton. While most “Paleo” folk don’t do dairy, this post may shed some light on why certain types of dairy may be good to go.

Other minerals are critical as well. Calcium must also be in-balance with potassium and trace elements like boron, copper and zinc. (3)

This balance is critical, and nearly impossible to achieve definitively using supplements and a Standard American diet. Step back, eat well, and let your body fall into balance based on its innate ability to prioritize and utilize the nutrients from Real Food (and Sunlight).

Co-Factor 6: Fatty Acids
Fatty Acids are responsible for the transport of calcium across cell membranes. Polyunsaturates decrease the stability of the cell membrane, and saturated fats strengthen it. That’s why both – in natural form – are critical to homeostasis. Natural polyunsaturates are found in abundance in oily fish, and saturated fats are found in coconut oil and ghee. Lard and tallow are great sources as well.

Additionally, fats and cholesterol are critical in the creation and synthesis of hormones (discussed above), although not all Fatty Acids are created equal. A study from Purdue University indicated that high levels of free radicals from linoleic acid (an Omega-6 fatty acid found in excess in the Standard American Diet because it’s found principally in unhealthy, highly processed fats like corn and soy oils), interfered with bone-building. (2)

Co-Factor 7: Exercise.

Exercise builds bone strength. (I think the audience understands this one.)

So there you have it: The Calcium Rundown. Memorize it. Carry a copy with you at all times. An optimized “Paleo Plus” plan – with some Weston A. Price thrown in – takes care of calcium status by being naturally replete in both calcium and the 7 Calcium Co-Factors. Processed foods and the Standard American Diet are NOT high in these co-factors. End of (long, delightfully complex) story.
