Have you heard of your fight-flight-freeze-fawn response? Of course you have, we all have. When we have sudden fright, scare, fear, or stress, our body is mobilized and ready to run or fight that stressor. That scare is registered by our brain and alerts the adrenal glands to make the hormones adrenalin and cortisone as our body readies for action.

I’ve been discussing magnesium this week. Did you know that when you have proper amounts of magnesium on board your body that your fight-flight reaction is kept balanced to just what you need to respond and not go overboard with the adrenalin and cortisone?

When you are deficient in magnesium, the adrenals can just go crazy with the adrenalin and cortisone and over respond. Too many of these hormones have a damaging effect. I’m sure you’ve heard of too much cortisone causing problems like depositing fat in the middle part of the body/abdomen, elevating blood sugar and elevating blood pressure.

When someone is under a lot of stress, I will often prescribe extra magnesium to counterbalance the adrenalin and cortisone their adrenals will be making.

This is why magnesium is known as a relaxing, chilling out supplement.

Continuing my discussion of magnesium, the most common mineral deficiency.

Did you know that magnesium deficiency can cause high blood pressure? Yes, it can.

What is high blood pressure? Everyone knows what it is, but do you know how it happens? The heart must beat to push blood from the heart out through all our arteries to feed our cells with oxygen and nutrients. There must be some pressure within the arteries to keep the blood moving along. Magnesium is part of a complex interplay of nutrients and chemicals that keep the blood vessels at the correct pressure to keep blood moving through. Magnesium mainly works by keeping the blood vessels more open/dilated to let the blood get through. Magnesium has a relaxing effect on the blood vessels. We do have other chemicals that will make our blood vessels contract or tighten. This is part of that delicate interplay, when each are at their correct levels, the blood vessels are at the perfect pressure. When magnesium deficiency occurs, the dilation/relaxing effect goes down, and the tightening effect is more pronounced. When the blood vessels tighten, the blood pressure will go up.

If I am working with a patient with high blood pressure and we are trying to get it down naturally and avoid blood pressure medications, there is a whole host of things I do, but you can bet that magnesium supplementation and getting rid of refined carbs are a big part of the plan to help that patient.

You know how I am constantly saying that vitamin D is the most common vitamin deficiency and magnesium is the most common mineral deficiency?

This study gives us some stats on magnesium deficiency. 67% of women and 64% of men are deficient in magnesium and a whopping 80% of people over age 71 are deficient.

These are huge numbers.

What is the culprit? It is twofold.
1. Not eating enough food in the diet to give us magnesium. Foods high in magnesium are salmon, oats, beans, whole wheat, nuts and seeds, brown rice, quinoa, raisins, prunes and dark chocolate.

2. Eating crappy, refined carbohydrates. Why does this make us magnesium deficient? The refined carbs are things like white bread, pretzels, crackers, cereals, pasta, pastries, etc. What is the common denominator of all these products? WHITE FLOUR. Is white flour the same as whole wheat flour? Nope. Wheat is stripped of fiber and most of its nutrients when it is made into white flour. You guessed it, the magnesium is one of the things that is stripped out.

But, but, but, Dr. Duffy, I’ll just get my magnesium from other sources so I can eat my white bread and pasta and crackers, you say. Oh, dear one…no. When you eat the crappy white refined processed crap, not only is the magnesium taken out of the food, but when you eat that food, it actually robs your body of magnesium (and other nutrients) just to digest and metabolize the food through your body. Nature puts magnesium in the food and that not only nourishes us with magnesium, but it makes the magnesium available to help your body digest and process the food!

Keeping with the theme of vitamin C, I thought I’d finish out this week with another reason we need plenty of vitamin C on board our bodies to stay healthy.

Earlier this week I talked about collagen protein. Collagen makes up the bricks and drywall that is the structure of our bodies, one of which is the skin. When we age, we lose collagen and our skin begins to sag and wrinkle, just like a house can do when time weakens the bricks and walls and causes the house to deteriorate.

Our bodies do have the ability to make collagen. While getting collagen in our diet is still very important, we don’t have to get all the collagen we need that way, we can make it ourselves. When our body makes collagen, it cannot do so without vitamin C. C is a necessary co-factor.

Let me share a clinical gem about vitamin C and collagen. Collagen keeps our skin supple, hydrated and less wrinkled. Have you ever noticed smokers’ skin, even when they are relatively young? Do you note more wrinkles than one would expect for their age? This is extremely common in smokers. Why? Smoking puts crappy chemicals inside our body, called oxidants (see yesterday’s post). Oxidants cause damage, so the body sends vitamin C to squash the oxidant chemicals, because vitamin C is an antioxidant, it puts out the fire. When people smoke regularly, they run out of vitamin C by constantly having to put out all the fires they keep causing inside their bodies. If vitamin C is being diverted to squash the smoking oxidants, there is less left over to help your skin make collagen, hence early onset of wrinkles in the smoker.

Yesterday’s post was about upping your vitamin C when sick with a cold to get past the cold faster.

Today’s post is a description of how vitamin C works in your immune system to help you get past being sick.

Vitamin C:
-helps certain white blood cells move more efficiently to the site of infections so they can work on killing the virus or bacteria.
-help the white blood cells do their “PacMan” duties to gobble up viruses and bacteria.
-helps white blood cells convert to other specific white blood cells to boost their numbers. These cells are specialized for defending against invaders, before they even make you sick.
-acts as an antioxidant. An oxidant is a chemical that damages our cells by changing the genetic code or killing the cell. When we have an infection, the white blood cells, out of necessity, make oxidant chemicals to help kill the viruses and bacteria. We need plenty of vitamin C on board to act as a neutralizer to these oxidant chemicals once they are done killing the viruses and bacteria so that the oxidants don’t go on to damage our healthy tissues.
-it helps what I call the “janitor” white blood cells go to the site of the infection where all the dead viruses and bacteria are to clean up the battlefield.

I hope you can see how important vitamin C is to keep your immune system healthy and in tip top shape when you get an infection.

Does vitamin C help with colds? The literature does indicate that it helps to reduce the severity and duration (how bad and how long) of cold symptoms.

This meta-analysis (combination of many studies’ data) found that people who take vitamin C as a regular supplement daily and took even higher doses when sick with a cold, found that taking the extra doses while sick helped to recover them from the cold faster than people who continued to take the same regular daily dose.

Take home information: I do recommend a daily vitamin C supplement, either by itself or within a multivitamin. The study tells us that when we get a cold, we should increase vitamin C to help us get over the cold faster. Once past the cold, you can reduce your C back down to the normal daily dose.

Is the fuss about collagen as an anti-aging helper worth the hype? It’s not a miracle but it can be helpful. As we age, we tend to reduce the amount of protein we are eating as our digestive tract has a harder time digesting it. Adding digestive enzymes here can be helpful to get your protein intake back up to the amount your body needs. The thing is, collagen is found mainly in the connective tissue of the proteins we eat, for instance, it is in the chicken skin, the tougher fibrous tendons and connective tissue in meat, and can you guess it? Most people are not eating these parts of the meat! This is why I have added bone broth to my daily regimen. I home make bone broth in my Instant Pot and drink 8 ounces a day. Search my page for bone broth to see how I go about it.

Back to whether getting more collagen is worth the hype. Studies too numerous to list out here do show small changes in the skin with reduction of wrinkles and hydration of the skin, but we are in the range of 20% improvements.

I am not taking bone broth for the collagen to reduce the wrinkles on my face. I do it because collagen is basically the bricks and drywall that hold our body together. If I see the effects of aging in my skin, I can be sure that the rest of my body is suffering these effects of reduced availability of collagen. I want to slow down the aging process, not to look better, but to function and feel better inside my body. The effects on wrinkles are a bonus.

This study on one of my favorite topics, Vitamin D, showed that exercise helps to reduce the winter dipping of vitamin D levels.

Overweight and obese people who were not taking vitamin D supplements were either enrolled in an exercise program four days a week or assigned to the control group. Blood measures of vitamin D were taken before and after the study period. It was found that the people in the exercise group lost 15% of their vitamin D but the control/sedentary group lost 25% of their D.

Granted, everyone can supplement vitamin D, but this study indicates that exercise has more effects than we are aware of as is noted in the difference between the two groups and how much their vitamin D levels dipped in the winter.

Happy April Fools’ Day. Where did this silly event start? There is not a clear answer to this.

One hypothesis is that the Gregorian calendar in 1582 changed New Year’s Day from April 1 to January 1. News travelled slowly back then, and people either did not hear the news of the change or refused to adhere to it. Those who continued to celebrate the New Year on April 1 were referred to as April Fools, hence the term.

Another hypothesis is that in Europe, it was common for spring festivals to revolve around silliness, hilarity and altering your identity. Disguises might be worn or the clergy and commoners would mock royalty and other authorities.

No matter its origin, the reason it stays is to celebrate a lighthearted rebellion, some good-natured humor and a day to chill and not take things so seriously.

A recent chiropractic podcast went over three studies done on Medicare patients with neck pain and gave us the low down. Short story – once again, chiropractic is superior to medical intervention regarding cost and effectiveness.

Medicare aged patients with neck pain were split into three groups.
1. Chiropractic care
2. Primary care with pain medication
3. Primary care without pain medication

The patients were followed for 24 months and three measurements were taken.
1. Rate of care escalation (this is college terminology for how many patients had to have more interventions done to treat their neck pain).
2. Cost to treat.
3. Safety of treatment.

Results:
1. The chiropractic care group had 64% lower care escalation, 93% lower surgical care and 78% lower hospital stays.
2. Chiropractic care group costs an average of $435 less per patient if hospitalization was eventually needed, reflecting lower costs for hospital stay and pain medication. This number would save Medicare $43 million per 100,000 Medicare patients with neck pain.
3. Chiropractic care group had 20% lower adverse events compared to the pain medication group and 14% lower adverse events compared to the non-pain medication receiving group.

I blab at every patient until their ears want to fall off about their diet, exercise habits, etc. I rail here 4 days a week about making better choices for your current and future health. Despite this, my 39+ years of clinical experience with my patient base has taught me that there is a core group of these little darlings who won’t do something to change their lifestyle until the $ #!% hits the fan and they are in trouble and scared.

Sometimes I can reach one of these resistant patients with some numbers on their blood work (if I can talk them into getting their labs done). I can point out that something is awry and will only worsen unless they do X, Y and Z. I’ve also been known to throw in a little incentive of how their family would feel if they developed a chronic or serious health condition.

I recently learned a new laboratory test that can help me help my patients that are at risk of heart disease and diabetes. I plan to use this test as a gentle coaxer to help patients make better choices.

The test is a ratio of two numbers that are done on routine blood work, in the lipid/cholesterol profile. One test is called HDL and is your “good” cholesterol (hate that term but that is a story for another day) and the other is called triglycerides, another type of fat in the blood that is measure on the lipid panel. Triglycerides are seen elevated when someone eats too many carbs, refined carbs, sugar and alcohol. The HDL/good cholesterol lowers when the body is under stress from too much sugar. These two things combined are caused by EATING REFINED CARBS AND SUGARS AND ALCOHOL.

The Triglyceride/HDL ratio is MORE ACCURATE FOR PREDICTING HEART DISEASE AND METABOLIC SYNDROME THAN LDL/THE “BAD” CHOLESTEROL IS.

Let’s say this again. Most medical practitioners are concerned with your LDL – the “bad” cholesterol (hate that term also, but another story for later) and want to get that number down at all costs, including prescribing statin medications. But a much more accurate predictor of heart disease and metabolic syndrome is this Triglyceride/HDL ratio being elevated. This ratio is NINE TIMES MORE predictive of heart disease than LDL alone.

If you have a recent lipid panel on yourself, find Triglycerides and write that number down, then find HDL and write that number down. TG/HDL. On a calculator, put in the Triglyceride number and then divide it by the HDL and you will get a number.

1.9 and under is great, low risk for heart disease and metabolic syndrome.
2.0-3.4 – red flag.
3.5 and above – high risk for heart disease and metabolic syndrome.
Perhaps seeing that your ratio is elevated may motivate you to change your habits. The fix is quite easy, it’s what I am always harping on.

No refined carbs
No sugar
No alcohol
Eat only whole foods as nature gives them to us. Bread and pasta are NOT whole foods.

My daughter, Dr. Paige Heidrich, has a bachelor in both Music Education and Vocal Performance as well as Masters and Doctoral in Vocal Performance. Along the way, she became certified in Music Play, a class designed for 0–4-year-old children with a parent or caregiver in attendance. There is plenty of literature on the positive effects of music integration in children and their brain development. When she was actively teaching this class, Paige noted improvement in the children as the class progressed as far as coordination and pattern recognition.

I found this study that added more evidence for integrating a music class for young children. The study compared infants age 9 months in an age-appropriate music class against other 9-month-olds in a play situation only without music. The music intervention group showed that the part of their brain that helps them recognize patterns and be able to guess what comes next was stronger than the play group without music. This is important because speech uses these same neural pathways, so the argument is that the music play classes help to build the infants’ brains and prepare them for speech.
