Functional Medicine Research with Dr. Nikolas Hedberg, DC

In this episode of Functional Medicine Research, I interview Sally Norton in a discussion about how oxalates affect your thyroid and your health. We covered what oxalates are and how they can damage the body. We also discussed how oxalates affect gut health, liver health, thyroid health as well as all the symptoms and associated conditions connected to oxalates. If you're really struggling to get well, but your diet appears to be healthy, oxalates may be the missing link. Full Transcript on Oxalates and Thyroid Health Dr. Hedberg: Well, welcome everyone to "Functional Medicine Research." I'm Dr. Hedberg, and I'm really looking forward to my conversation today with Sally Norton. Sally is a consultant writer, educator, and speaker with over 30 years in the health promotion and wellness field. Sally specializes in helping people improve their health with an oxalate-avoiding diet. Sally holds a nutrition degree from Cornell University and a Master's of Public Health degree from the University of North Carolina at Chapel Hill. She worked in the field of medical education at UNC Medical Schools Program on Integrative Medicine and as a research grant writer and research administrator at the Virginia Commonwealth University School of Medicine. Despite a healthy lifestyle, she struggled for over 30 years with seemingly unanswerable health challenges, including chronic pain and fatigue. When she finally discovered the cause and turned her health around, she committed to teaching and reaching out to others stuck in similar frustrating situations. Sally, welcome to the show. Sally: Thank you. It's great to be here. Dr. Hedberg: Yeah, I'm looking forward to this and we were kind of discussing this early on. Oxalates is something that I've always kept my eye on for the last 17 years and I was really looking forward to this conversation. So why don't we lay a little bit of bedrock for the listeners? And if you could just talk about what are oxalates, and do we know why plants actually have oxalates? Sally: Yes. Plants are a major producer of oxalate and obviously, it's also ubiquitous in nature itself. Soil is loaded with it. Even apparently sea spray produces some oxalate and polluted air produces oxalates, so, in really heavily polluted cities, the air has got oxalate in it too. So oxalate is this really minuscule molecule that its parent compound is called oxalic acid. And acids ionize and become charged particles because they drop off the acidic protein and so they become these negatively charged ions that attract positively charged things and oxalates can have a one negative or two negative. It is a tiny, tiny little compound. It has four oxygens, which is a heavy load of oxygen on just two little carbon molecules. So it's very oxygen-heavy, which is probably partly why it's such a pro-oxidant molecule, you know. Oxidation is very bad for tissues, membranes, mitochondria, and it is a great mitochondrial poison, membrane destroyer, and troublemaker. And it's not just the oxygen, though. It's much more about this reactivity that the charge creates where it bonds with minerals and becomes salts. And so, salt is a chemical term for things that can dissolve, but when it...because it can have two negative charges, it will also hook up with minerals that won't dissolve well. So calcium, for example, is a two positive charge mineral. With that double-positive and double-negative marriage between the two, you create an insoluble oxalate, which is the backbone of oxalate you see in nature because calcium is everywhere in soils and in nature, and plants are having to manage their calcium. And one of the ways they do that...because too much calcium can be toxic to the plant. So one of the ways they do that is they make oxalic acid. Often they make vitamin C first, very similar compounds, and vitamin C naturally degrades just hanging around into oxalic acid and oxalates. So plants will create vitamin C and they'll cre...

Dr. Theodore Belfor on Cranial Facial Development

In this episode of Functional Medicine Research, I interview Dr. Theodore Belfor in a discussion on cranial facial development and airway resistance. If you have read James Nestor's new book "Breath" then you are aware of Dr. Belfor's work. We talked about the causes of abnormal cranial development and how this causes airway resistance and a number of health problems including sleep apnea, insomnia, IBS, bruxism, and more. Our cranial bones don't form properly when we aren't breastfed and eat a modern diet of processed foods. Dr. Belfor's oral appliances help to correct these abnormal developments to restore proper facial bone structure and improve the airway. Full Transcript with Dr. Theodore Belfor Dr. Hedberg: Well, welcome everyone to "Functional Medicine Research." I'm Dr. Hedberg, very, very excited today to have Dr. Theodore Belfor on the podcast. I first heard about Dr. Belfor in James Nestor's new book called "Breath." And we're gonna be talking about all of that today on the show. And Dr. Belfor, he's a graduate of New York University College of Dentistry, and a senior certified instructor for the International Association for orthodontics. In the 1960s, Dr. Belfor was sent to Vietnam to work as the sole brigade dentist for 4000 soldiers of the 196 Light Infantry from the jungles of Vietnam to Park Avenue in Manhattan. Upon his return, he opened his own private dental office in New York City, and has been in private practice for more than 40 years. And Dr. Belfor specializes in the treatment of the cranial facial system, and that's what we're going to be diving into today. So, Dr. Belfor, welcome to the show. Dr. Belfor: Well, thank you for having me. It's my pleasure. Dr. Hedberg: Excellent. So, why don't we start by talking about how this all began, and go back to, you know, what happened that changed the cranial bones, the cranial structure, our skulls, that led to this epidemic of airway issues, breathing issues, and all of the health issues that come with that? Dr. Belfor: Well, how we develop, how we grow and develop is based on how we breathe, how we swallow, and how we chew. So, just looking at how we chew, according to the U.S. Department of Agriculture today, in the U.S., 63% of our diet is processed and refined foods. So, without the proper stimulation to the body, we are not fully expressing our genes, we're not developing to our full potential. Because of that, particularly when our jaws do not grow forward enough, the retrusion of those jaws helps to push the tongue backwards into the airway and down the throat, so now we have compromised sleep and breathing. Dr. Hedberg: So, it's a combination of things. I know Dr. Nestor talks about it in his...or James Nestor talks about in his book, the changes in diet, soft food, not enough hard foods, not breastfeeding. Can you talk a little bit more about these changes in our society and some of these predisposing factors that can cause an abnormal airway? Dr. Belfor: Well, for me, the enlightenment came, when almost 20 years ago, I was treating performing artists who couldn't wear braces and they wanted straighter teeth, and I used an appliance and had a unilateral bite block, which basically, in essence replaces the missing hard food in our diet. And guess what? The actors, performers were coming in, and their makeup artist was telling them that their faces are changing, and the singers were coming in and saying they were reaching higher notes. So, that's what set me on the path. You see, the concept in dentistry is to balance the bite all the time. And it's kind of an anathema to have, when you bite down, to hit on one side. However, if I give you a stick of gum to chew, nobody on the planet is going to chew on both sides at the same time. We chew on one side then we chew on the other. And apparently from the research, many articles that have been written, the latest one in August 2018,

How to Increase Stomach Acid Naturally

Functional medicine practitioners often take a “Foods First” approach, recommending dietary modifications to improve health. However, for those with low stomach acid, diet alone may not be enough to ensure adequate nutrition. Low stomach acid can impair digestive ability, causing nutritional deficiencies even in those individuals consuming an optimal diet. This article will focus on the main digestive chemical associated with the stomach, hydrochloric acid. The causes of low stomach acid and the associated symptoms will be covered. In addition, natural treatment options for low stomach acid, such as betaine HCL and herbal bitters will be discussed. What is Digestion? Digestion is the process of breaking food down into particles small enough so that the nutrients in the food can be absorbed and then transported throughout the body. Digestion begins in the mouth with the mechanical process of chewing along with salivary enzymes that begin the digestive process. This process is continued as the food passes into the stomach, activating the release of hydrochloric acid. The bolus of food then passes to the small intestines where the majority of digestion takes place. The useful nutrients are digested and absorbed and the waste products are sent through the large intestines for evacuation as feces. Why Does the Stomach Contain Hydrochloric Acid? The stomach is a naturally acidic environment, especially following a meal, with a normal pH value of <3. Low stomach acid (hypochlorhydria) is observed with a rise in pH >3 and an absence of stomach acid (achlorhydria) is obtained with a pH > 7.1 This acidity comes from the hydrochloric acid that is secreted by the parietal cells in the lining of the stomach. Healthy stomach acid levels serve as an immune system barrier, providing a first line of defense against unwanted bacterial or microbial invaders that enter the stomach. Hydrochloric acid is also necessary for the digestion of proteins. Proteins are a conglomeration of amino acids folded together into different shapes. Stomach acid serves to denature (unfold) the proteins and expose the bonds that hold the amino acids together. These bonds can then be cleaved by pepsin, which breaks the protein down into smaller, easier to digest, amino acids. The formation of pepsin from pepsinogen is dependent on sufficient stomach acid levels as well. Hydrochloric acid is also responsible for deactivating the enzymes of salivary amylase as it enters the stomach and for stimulating the release of cholecystokinin in the small intestines. Both processes are essential for healthy digestive function. Certain vitamins and minerals depend on hydrochloric acid to liberate them from their carriers, such as vitamin B12 and calcium. Having low stomach acid levels can impair all of these functions. What causes low stomach acid levels? Factors that contribute to low stomach acid include: Chronic stress Aging Poor diet Infections Medication use Stress—Stress impairs digestion. Chronic stress may decrease the production of hydrochloric acid in the stomach due to associated nutrient deficiencies.2 Stress also causes the vagus nerve to lose its proper tone. The vagus nerve is a major part of the parasympathetic nervous system, and it is deeply involved in stomach acid production. With chronic stress it loses its ability to fire properly which disrupts normal stomach acid production. Aging—Low levels of stomach acid following a meal are more common with aging. Studies that compared stomach acid levels in young individuals (mean age 25) versus older individuals (mean age 75) found that older individuals experienced low levels of stomach acid following a meal for a greater length of time than their younger counterparts. It took 89 minutes for the elderly participants versus 42 minutes for the younger participants to regain normal stomach acid levels (pH 3.0) following a “standard meal”.1, 3,
