Question: Is whole food vitamin C superior to natural because it is part of a tyrosinase complex? Short Answer: Vitamin C is nearly ubiquitously distributed in plant tissues, and is never bound to any enzyme as a structural complex. Vitamin C promotes absorption of iron from plant foods, inhibits copper absorption, and de-loads copper from ceruloplasmin, which may play a role in distributing copper to tissues. Vitamin C is not capable of destroying ceruloplasmin. These functions follow directly from vitamin C as an electron donor and there is no evidence whatsoever that whole food vitamin C behaves differently in these respects than synthetic vitamin C. However, daily needs in most contexts are 2-400 milligrams of vitamin C per day, which is below the dose shown to potentially cause problems with copper. Getting this from whole foods or whole food supplements is better than using synthetic vitamin C because it avoids GMO corn and Chinese synthetics and provides a host of other beneficial constituents alongside the vitamin C.

Question: What Is the Real Issue With Seed Oils? Short Answer: The main issue with seed oils is that they present an oxidative liability. They do not acutely cause oxidative stress, but their polyunsaturated fatty acids (PUFAs) are more vulnerable than any other macronutrient to oxidative damage. Oxidative stress can increase because of nutrient deficiencies, toxins, infections, other sources of inflammation, alcohol, or smoking, and it will inevitably increase as a function of aging. As oxidative stress increases, more PUFAs in the tissues mean more damage. At least 0.6 milligrams of vitamin E should be gotten per gram of PUFA in the diet, but vitamin E cannot fully protect against PUFA, so their intake should be moderated to the very low levels needed, as obtained by eating fatty fish once or twice a week, eating eggs daily, and eating 4-8 ounces of liver per week. Additional secondary problems with them include residual solvents and heat damage prior to intake, but the main issue is that we do not want to increase our tissue PUFA content more than needed.

Question: How useful is hair trace mineral analysis (HTMA) for nutritional testing? Short Answer: Hair trace mineral analysis is included as an optional add-on in the comprehensive nutritional screening from Testing Nutritional Status: The Ultimate Cheat Sheet, because it can capture data for some ultra-trace minerals for which there are no better-validated tests, and it might capture a pattern that might not be picked up as quickly with blood work, such as a mineral transport issue. However, its utility is limited by the fact that hair mineral content is not well validated as a test for any specific mineral, is generally anti-validated when there is enough science on a mineral (such as zinc, where hair zinc does not go down in deficiency), and should not be used as a central piece of data without corroboration from other more well-validated tests, which exist for most of the nutrients.

Question: How to Find the Root Cause of Autoimmunity? Short Answer: Autoimmune conditions are likely driven by deficiencies of vitamins A and D, which contribute to post-infectious autoimmunity by compromising the rhythmic rise and fall of myeloid-derived suppressor cells (MDSCs), and to autoimmunity regardless of infections through impaired suppression of Th17 helper T cells. More broadly, infections and tissue damage are the most likely drivers of autoimmunity onset. However, energy metabolism governs everything through the second law of thermodynamics, which holds that energy must be used to prevent everything from randomly mixing, and this includes randomly mixing the immune defense against pathogens with immune attacks on the host. In this example, we discuss how a respiratory chain disorder would compromise absorption and distribution of zinc and compromise the oxidation of NADH to NAD+, and how both of these would interact with a genetic impairment in acetaldehyde dehydrogenase to prevent the activation of vitamin A to retinoic acid. Autoimmunity thus results as one of many symptoms of vitamin A deficiency driven not by lack of vitamin A, but rather by impaired activation of vitamin A, secondary to impaired energy metabolism.  This is a clip from a live Q&A session open to CMJ Masterpass members.

Question: Why Would Vitamin C cause muscle pain, joint pain, and brain fog? Short Answer: Acutely, vitamin C would likely cause these effects by generating oxalate, which could cause crystals that lead to muscle and joint pain, and could cut energy metabolism in half, leading to brain fog. This vulnerability could result from deficiencies of any of the B vitamins, any of the electrolytes, or of iron, copper, or sulfur; from diabetes, low adrenals, or hypothyroidism; or from any of the hundreds of genetic defects in energy metabolism, only one of which is glucose 6-phosphate dehydrogenase deficiency; or any one of a huge number of toxins that impair energy metabolism. Chronically, vitamin C may increase the harms of iron overload or contribute to copper deficiency. The main ways to manage these latter issues are to take vitamin C away from meals, to maintain good copper status through proper dietary intake, and to treat iron overload with phlebotomy.

Question: Can NAC hurt your gut health? Short Answer: N-acetylcysteine or NAC can be used at a dose of 600 to 2,400 milligrams per day for 5-10 days to disrupt biofilms and make it easier for antimicrobials to kill bacteria. Animal studies suggest that acute doses up to 6 grams do not deplete mucus or cause ulceration, but that an acute dose of 17.5 grams can deplete mucus and cause ulcers within two hours. Human studies suggest that 10 grams per day can be used for 24 weeks with fewer than 1 in 6 people complaining of gastrointestinal side effects. Yet, chronic use of NAC will thin the mucus, disrupt the biofilms used by normal healthy microbiota, and possibly deliver excessive sulfur to certain components of the microbiome. Therefore, I would not use it except for specific, targeted reasons, and I would not use it at a dose higher than needed or for a duration longer than needed.

Question: Why should postprandial blood glucose be kept under 140 milligrams per deciliter? Short Answer: When blood glucose rises above 140 mg/dL, this is the approximate point at which it spills into the polyol pathway at a greater-than-normal rate, which represents a suboptimal state of metabolism that is likely to hurt antioxidant status and compromise detoxification pathways as well as the recycling of vitamin K and folate. It must be kept in mind that a healthy person will adapt to glycemic loads they consume regularly. Thus, a one-time spike above 140 mg/dL should never be used to conclude anything whatsoever. Only repeated spikes above this level with repeated consumption of the same glycemic load over several days to several weeks should be used as a cause for concern.

Question: What is the relationship between copper and estrogen? Short Answer: Estrogen moves copper from the mother's bloodstream to the fetus during pregnancy. Its action at the intestines is poorly understood but I believe estrogen and progesterone interact to promote intestinal copper absorption. Maintaining pregnancy-level hormones while not pregnant poses a risk of promoting too much absorption of copper from food without transferring it to a growing baby.

Question: How to slow graying of hairs and potentially reverse it? Short Answer: What works for any given individual will likely be to find the weakest link and fix it, from among the following systems: the signaling of energy abundance (body fat, insulin sensitivity, thyroid hormone, adequate protein, individualized meeting of carbohydrate needs, good management of psychosocial stress, supporting neuroendocrine signaling with copper, vitamin C, zinc, and glycine, and supporting thyroid function with iodine and selenium); the biochemical infrastructure of energy production (all the B vitamins, iron, copper, sulfur, magnesium, potassium, and managing genetic idiosyncrasies impacting energy metabolism), and antioxidant protection (protein, vitamin C, vitamin E, zinc, copper, selenium, iron, and manganese).

How Much Iron Can We Absorb At Once? | Masterjohn Q&A Files #320

Mastering Nutrition

Question: How much iron can we absorb at once? Short Answer: High-dose iron will produce more total absorbed iron, but will also leave more in the gut, which could cause constipation or disturb the gut microbiome. If desperate for quick relief, 200 milligrams per day of iron taken in the morning will work faster than lower doses or the same dose taken in the afternoon. For most people, however, I believe it is best to start with 18 milligrams of iron, and only increase it to 27 or 36 milligrams, or higher, if needed. If it is difficult to raise iron with a supplement, try eating a temporary carnivore diet that includes egg yolks but not whites, or at least try taking your iron with a breakfast that matches this description.

Question: What cofactors are needed to synthesize and recycle BH4? Short Answer: Zinc, magnesium, potassium, and niacin are the cofactors needed for the synthesis and recycling of BH4.

Question: Is it important to get vitamin D sulfate specifically from the sun? Short Answer: It is important to get morning outdoor sunlight as close to every day as possible for your circadian rhythm, and to get some exposure to unprotected sunlight during the day when UV is available, but at doses less than needed to cause reddening, and it is equally important to always avoid burning. There are many reasons for this, and the cholesterol sulfate hypothesis — to which the vitamin D sulfate hypothesis is peripheral — is an interesting and worthy hypothesis but should not be the final arbiter of your sun exposure habits.

Question: If a person has a hereditary weakness for Branched Chain Amino Acid Catabolism would this impact the type of diet they might choose to loose weight? Should they limit protein if it will increase their need for nutrients like Biotin?What are all the possible cofactors we should consider supplementing to support Leucine catabolism? Short Answer: Metabolizing branched-chain amino acids requires all B vitamins except folate, calcium, magnesium, potassium, and chloride. If you have a genetic impairment in this pathway, then reducing branched-chain amino acid intake and doubling down on cofactors is important during weight loss because the pathway will be stressed more in the catabolic state.

Question: If I don't want to hurt my omega 6 status through my omega 3 intake, how do I do that? Is it simply a question of taking them at separate times? Or is it a question of dose? And if it is a question of dose, how do I know when to start eating fish and taking my omega 3 supplement again? Short Answer: How they are combined in meals is not important, but it is important not to have too much EPA in cell membranes relative to arachidonic acid, and this is driven by cumulative intake over years. For someone who has consumed too much EPA for many years, the best approach is to eat liver and egg yolks for arachidonic acid while getting omega-3s from a DHA supplement and not from fish, fish oil, or fish liver oil.

Short Answer: On a scale of one to ten, my concern about TMAO and cardiovascular disease is a three. There are thousands of things that should be given equal weight as potential contributors to heart disease, but TMAO gets the most attention because the Cleveland Clinic has an incredible PR machine to spread their research, which serves to bolster their financial interest in marketing the test. That said, it is not a universal necessity to supplement with phosphatidylcholine.

Question: How do I fix low blood sugar on vegan keto? Short Answer: Consider how important it is for your ketones to be elevated. Most likely you need to eat more protein, which will lower your ketones. I would aim for a minimum of 0.8 grams per kilogram of ideal bodyweight and consider using 1.2 grams per kilogram of ideal bodyweight. If this does not work, consider all of the nutrients involved in energy metabolism — all of the B vitamins, iron, copper, sulfur, magnesium, potassium — but especially biotin and B6 for their disproportionate role in gluconeogenesis. If the protein you need to normalize your blood sugar does reduce your ketones to a level that are not giving you the benefits you are looking for, you could consider raising them with exogenous ketones.

Why Plasma Zinc is the Best Marker of Zinc Status | Masterjohn Q&A Files #309

Short Answer: Plasma zinc is the single most important marker of zinc status. Urine zinc may decline faster in deficiency. Hair zinc increases with supplementation but does not decrease in deficiency. Plasma zinc is decreased by inflammation, oxidative stress, the ovulatory and luteal phases of the menstrual cycle, probably pregnancy and oral contraceptive use, and any kind of stress that leads to an adrenal output. If plasma zinc declines despite supplementation, corroborate that this reflects zinc status by showing normal hair zinc and low urine zinc. Use symptoms as the ultimate arbiter of whether zinc supplementation is helping. This is a clip from a live Q&A session open to CMJ Masterpass members.

Short Answer: From the trials, statins seem to reduce heart disease risk and total mortality, but it is impossible to separate this from conflicts of interest and industry funding. There are plausible mechanisms by which they may hurt mitochondrial function and promote soft tissue calcification. Dietary sulfur appears to lower cholesterol. While Lester Morrison showed 1500 milligrams per day of chondroitin sulfate could reduce cardiac events 7-fold, this has a theoretical potential to hurt the microbiome. My preferred way of getting sulfur is 1.2-1.8 grams per kilogram bodyweight of total non-collagen protein, with an emphasis on animal protein.

Short Answer: The main problem with too much protein, particularly animal protein, is that acidity may hurt the bones and increase the risk of calcium oxalate kidney stones, but this can be obviated by balancing it with organic acids, which have bicarbonate-sparing effects that are alkalinizing. The best index of the organic acid content of foods is the potassium content. This balance can be achieved with 750 to 1500 milligrams of potassium for every 100 grams of protein.

Short Answer: Energy metabolism in general declines across the body with aging, but energy metabolism seems to stay healthy enough in the brain in people who do not experience cognitive decline. Cognitive decline does appear to be driven by decreases in brain energy metabolism, but these are not best described as a specific impairment in glucose handling. MCT oil can be modestly beneficial and a ketogenic diet can probably be somewhat more beneficial in people who have cognitive decline from any type. There is no evidence to support using it as a preventative. For prevention, I believe we should focus on aerobic fitness, nutrients required for healthy energy metabolism and antioxidant defense, and maintaining metabolic health with a healthy body composition and a healthy physical activity routine that includes the proper spread of a portfolio of different types of exercise.

MASA chips are made from organic corn from small New England farms. The corn is nixtimalized, which frees the niacin, makes it more digestible, and eliminates 97-100% of the mycotoxins (based on studies with aflatoxin). Then they are fried in grass-fed beef tallow! They are full-bodied and feel nourishing, and they are the perfect saltiness. That is, I do not feel like a company has tagged me as eating a low-salt diet just because I want a healthy chip. The bulk of your diet should be unprocessed and minimally processed foods, but there is an important place for health snacks!

Certainly, the fat-soluble vitamins, vitamins A and D, both important. Lauric acid as a fat. Coconut oil might be a good fat choice for the fat in your diet. Monolaurin would be a very good choice for a supplement. Lauricidin is the best monolaurin to take, 3 to 10 grams a day. Be careful of your bowel tolerance, spread it out among your meals, and cut back if it starts to loosen your stool. Elderberry, which has mostly been studied in the context of flu, that probably has good antiviral properties. Garlic. Garlic appears to require very high doses if you're just taking a garlic extract. If you're taking stabilized allicin, 180 micrograms a day is good. But you could raise the question what if you're missing on some of the other important compounds in the garlic. I'll debate with some of my friends about that, but what's really been tested is 180 micrograms of stabilized allicin. Then zinc for sure in the immune response is super important. Then you get back to nutrient density. Although I'd give special importance to vitamins A and D, arachidonic acid just mentioned, zinc and copper, both, and then those supplements. If you're missing any one particular nutrient, then you're going to wind up with a specific vulnerability that will persist until you fix that one nutrient. Thanks, anonymous.

Best clinical way to monitor COMT function if you have already tested for SNPs | Masterjohn Q&A Files #04

Mastering Nutrition

"What do you think is the best clinical way to monitor COMT function if you have already tested for SNPs?"   One way you can look at it is through the DUTCH test — which is at dutchtest.com — it's a dried urine hormone testing platform, they have a methylation index that is based on the methylation of estrogen. For example; the main significance of COMT, is related to long-term risk of estrogen-related cancers.     Acute symptoms are primarily going to manifest in the brain in the relation between COMT and dopamine.    The higher your COMT activity, the more flexible your brain.    The lower your COMT activity, the more rigid your brain.    If your nutrition is straight and you don't have a psychological disorder, that's just a personality trait.   They call this the worrier/warrior, phenotype.    High COMT activity; you don't worry as much, like a warrior who picks his battles, wins, and repeats. There is nothing to worry about, the only concern is victory.   If you are a low COMT activity; you're not a warrior, you're a worrier. You think about all the possible ways something could go wrong. Instead of moving forward with an image of invincibility, you struggle to move at all, like a deer in the headlights.    But that's the extremes. Within most of the population, it's just a personality trait.    So, you really look at, how is your mind operating? If your mind is getting stuck on stuff, low COMT. If your mind is racing around to different things, high COMT. If that's just your personality, don't worry about it. But if it's starting to interfere with your life, then that's where it matters.    Low COMT, focus on methyl donors: B12, folate, choline, betaine, some of the other assisting B vitamins.    High COMT, focus on  methyl buffers: Glycine.    This Q&A can also be found as part of a much longer episode, here: https://chrismasterjohnphd.com/podcast/2019/02/09/ask-anything-nutrition-feb-1-2019/

Supplements that may increase deep sleep | Masterjohn Q&A Files #03

So, deep sleep is, primarily what's going on in deep sleep is that all of your biogenic amines, which are most of the neurotransmitters that you make from protein with the possible except — like depending on how you classify it, you could say ultimately you make melatonin from protein, but it's not a biogenic amine. Biogenic amines, which are the catecholamines — all are basically shut off. They're probably not zero, zero, but they're almost zero during sleep. Acetylcholine is also shut down during deep sleep, but it pops up during REM sleep. I really don't think this is a supplement issue.  First of all, you definitely don't want to be taking anything that has acetylcholinesterase inhibitors at night.  Non-organic foods have pesticides that are acetylcholinesterase inhibitors. I don't know if that's relevant here dose-wise. Things that improve cognitive function are often acetylcholinesterase inhibitors. So, gingko biloba is one. I wouldn't take that at night. There are drugs that treat neurological problems, especially Alzheimer's, that are acetylcholinesterase inhibitors; I wouldn't take those at night.  I'm on the fence about whether you should take choline at night. I think it's most likely fine to eat eggs at night. If you're taking something like alpha-GPC; I'm not sure. You might want to avoid that at night if you find, particularly if you find that when you're tracking your sleep with an Oura ring your REM is higher than normal and your deep sleep is lower than normal.  But other than that — I would say that methylation support is very important to help lower some of the important biogenic amines. Histamine, for example, is primarily gotten rid of with methylation in the brain and if your histamine levels are high during the day, it might cause anxiety during the night and that could interfere with your deep sleep. Electrolytes are also super important. Calcium, magnesium, salt and potassium. All these things you need to get straight in order for your sleep cycle to be working right. If your cortisol is high at night or other factors of anxiety are high at night you might want a targeted supplement there, like phosphatidylserine — the evidence is conflicting, but has been used to lower the stress response.  I don't think it's a blanket answer to that question. I think it's like figuring out what's the cause of the low deep sleep and working from there.

Despite a shifting scientific landscape, dietary cholesterol is still a hotly debated topic. Joe Rogan and Chris Kresser eat eggs every day, while the plant-based community still loves to highlight the supposed dangers of dietary cholesterol. High cholesterol has historically been associated with poor health, but is there a range where cholesterol levels get too low? Our guest in this episode of the podcast believes the combination of a genetic predisposition combined with a strict vegan diet caused him to develop a dangerous cholesterol deficiency. A former assistant professor of Nutrition Science at Brooklyn College, Chris Masterjohn, Ph.D. is one of the smartest minds in nutrition. Chris shares a fascinating story of how going vegan caused him to develop nutrient deficiencies which led to a battle with mental illness and anxiety. Chris' subsequent focus on nutrient-dense, animal-based foods restored his health and changed his perspective on how the foods we eat play a large role in cognitive function. We cover a wide range of topics with Chris and he takes a number of controversial positions in this episode, including who shouldn't eat eggs, nutrient deficiencies that are most likely to arise on a carnivore diet, whether “fancy” blood testing metrics like LDL-P are necessary to gauge cardiovascular health, why some people fail on vegan diets and much more.
