Blood Sugar Dysregulation and Mineral Balance

 

The majority of conversations surrounding blood sugar issues like diabetes, hypoglycemia, and insulin resistance are focused on macronutrients.  The immediate reaction is to ask about the dietary balance of carbs, proteins, and fats, which can be partially misguided.  Balanced meals are an essential part of blood sugar balance and a crucial component of adrenal and thyroid health.  However, if someone is dealing with many spikes and dips in their blood glucose, we have to fight the temptation always to assume that their macronutrient ratio is off due to carbohydrate consumption.  Yes, eating carbs does cause your blood sugar to rise, and depending on the person, it may lead to a severe drop.  For this reason, low-carb diets have exploded in popularity over the last decade, slowly phasing out the fear of fat ignited by physiologist Ancel Keys in the 1950s and replacing it with a deep-seated disdain for anything that turns to glucose in the blood.  

These days society pushes a different diet on us for every symptom.  Overweight?  Try the Atkins Diet.  Have blood sugar issues?  Follow the Keto Diet. Are you feeling sluggish?  The Carnivore Diet will change your life.  The current consensus is that we simply don’t need carbs to survive.   We’re starting to see with our clients that the demonization of this particular macronutrient is leading to disordered eating tendencies in women and a worsening of symptoms overall.  Which leads us to ask the question: Is the consumption of carbs over time the culprit of metabolic issues like PCOS and insulin resistance?  Or is there something else at play here?  To get to the bottom of this problem, we have to look at all of the information we have available to us about what impacts blood sugar regulation—and minerals is a big one.  Let’s get specific.

 

 

Potassium's Effect On Blood Sugar


We've discussed the importance of potassium for so many different functions in the body (including regulating blood pressure, maintaining fluid balance and pH of the body, impacting nerve conduction in the heart, and dilating arteries) but how exactly does it support blood sugar balance?

The answer is three-fold:

  1. Potassium sensitizes our cells to thyroid hormone, which means we need potassium in order for our cells to receive thyroid hormone. If our cells don't have enough of this important hormone, they become less sensitive to insulin (the hormone responsible for shuttling glucose into the cells
  2. Potassium has insulin-like effects, helping get blood sugar into cells. If glucose can't get into the cells, whether because of insulin resistance or lack of insulin, it hangs out in the serum creating high blood sugar levels.
  3. Potassium is involved in the conversion of glucose (blood sugar) into glycogen (stored blood sugar) in the liver for future energy. Not having enough liver stores of glucose means that our bodies are forced to use alternative fuel sources in between meals, raising the risk of blood sugar dips.

This may be why we're seeing recent research suggest that lower levels of potassium in the blood can lead to greater risk of developing Type 2 Diabetes. And interestingly, the best way to get potassium through your diet is with carbs, especially potatoes, coconut water, squash, and fruit.


 

 

Effects of Magnesium on Blood Sugar

Women’s Health Naturopath, Lara Briden, calls magnesium the “natural Metformin” because of its ability to regulate blood sugar and normalize insulin.  So, what does magnesium do to support blood sugar balance?  

  1.     Magnesium is not only a cofactor of many enzymes involved in glucose metabolism, but it also controls how our bodies process sugar.  It controls the action of insulin and insulin-reliant glucose uptake at the cellular level.  On the other hand, magnesium deficiency has been shown in studies to induce hyperinsulinism (when the beta cells of the pancreas release too much insulin).  

Hyperinsulinism causes low blood sugar in the short term, but in the long run, the pancreas will wear itself out, and the cells in the body will become resistant to insulin, resulting in—you guessed it—high blood sugar levels.  Overall, chronically low magnesium levels can impair the action of insulin and increase insulin resistance, contributing to conditions like PCOS and Type 2 Diabetes.

  1.     Like Potassium, magnesium is also required for the production of thyroid hormone, which, as we’ve already established, directly impacts insulin sensitivity.
  2.     Lastly, magnesium lowers cortisol by regulating the stress response and reduces blood glucose levels.  When cortisol is released into the bloodstream, so is glucose!  As you can see, magnesium is 100% required to metabolize glucose properly, and most of us are burning through our stores at rapid rates because of stress.  You can read more about the benefits of magnesium and how to supplement it in my blog post.


 

 

Effects of Calcium on Blood Sugar

The role that calcium plays in blood sugar balance is slightly different from that of potassium and magnesium.  While calcium does have its own set of functions and health benefits, an overabundance of calcium in the body can have a negative effect on blood glucose levels.  Why is that?  High calcium levels often show up as a result of chronic stress and can lead to a deficiency or loss of magnesium, sodium, and potassium.  When these mineral ratios are out of whack in calcium’s favor, many problems can arise in the body.  Here are different ratios and what they mean:

  1.     High calcium/magnesium ratio- is associated with high insulin output, as calcium supports insulin release from the pancreas.  As mentioned above, we need sufficient magnesium to counterbalance insulin and regulate blood sugar.
  2.     High calcium/potassium ratio- indicates sluggish thyroid function and a decline in energy production efficiency in the body, contributing to glucose metabolism.
  3.     Most of the time, people with elevated calcium on their HTMA test will present with a low sodium/magnesium ratio, suggesting sluggish adrenals.  When adrenals have been exhausted, blood sugar dips are common.

For lowering calcium, a vitamin K supplement helps usher this mineral out of soft tissue cells and putting it in places where it should be, like bones and teeth.  Iodine therapy can also help with elevated calcium, but we don’t recommend doing this without the supervision of a health professional.  If you want to get on our waitlist for functional lab testing, you can sign up here.  

 

 

 

When treating conditions like PCOS, insulin resistance, and diabetes, we can’t just look at macronutrients.  There is so much more to the blood sugar puzzle, and I’d say that micronutrients are a BIG factor in glucose metabolism and regulation.  Despite what mainstream health experts will have you believe, the answer is not always to eliminate or minimize carbohydrates in the diet.  Doing so is only placing a temporary band-aid on a much deeper issue.  It’s only when we balance our minerals like calcium, sodium, potassium, and magnesium that we’ll begin to see actual progress in blood sugar balance.
