Question: Is dairy safe for overmethylators?There's so little methylcobalamin in milk that I think that it is totally insignificant with regards to methyl groups, coming into the methylation cycle. Generally, if you're experiencing over-methylation symptoms from methylcobalamin or methylfolate, I think the big issue is partly that you don't have enough glycine in the system, very likely, and partly that your body is over-accustomed to low methyl supply and putting more suddenly into it leading into the system being adapted to a different state than the one you're putting into it. But if you find it is, you're reacting to dairy, I would be very surprised if it was the methylcobalamin, but if you're very convinced of that, then titrate up slowly with the dairy.If you would like to be part of the next live Ask Me Anything About Nutrition, sign up for the CMJ Masterpass, which includes access to these live Zoom sessions, a private discussion group, premium features on all my content, and hundreds of dollars of exclusive discounts.

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.

Is Whole Food Vitamin C Really Different? | Masterjohn Q&A Files #330

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.

What's the Deal With Seed Oils? | Masterjohn Q&A Files #329

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.

Vitamin C, Whole Food Vs. Synthetic: Does It Matter?

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.
