Question: What is the value of third party genetic reports?There are very, very few genes where we have really good information on how they impact nutritional requirements, but we have many, many, many genes where we have decent information on what they do mechanistically and where we can speculate things that might be helpful. So genome analysis is very useful as a brainstorming mechanism. And of course, there's genome sequencing in a clinical context to identify rare metabolic diseases, a totally different thing. That's obviously useful for where it's been defined as being useful, but doing a 23andMe analysis and submitting it to a report is useful for brainstorming and potentially generating some explanations for things that you observed. And I think Self-Decode did a really good job in distilling, first of all, taking a lot of conflicting polymorphisms and distilling them into a net result. And then, second of all, distilling some actionable principles. Third of all, noting where they're brainstorming and providing references to give some reasonable level of confidence of exactly.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: What is the value of the oxidized phospholipids test?It's interesting to measure, but we don't have real strong data on its correlation to disease risk.  And we also don't really know how much it reflects the oxidation of lipoproteins in the subendothelial space, which is what matters.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: Can NADH supplements cram more NADH into the system?The NADH will be hydrolyzed to something along the lines of nicotinamide riboside, it will be absorbed and it will act like nicotinamide riboside does, which will increase the amount of nicotinamide stored in the liver for release to the tissues. And that will help increase their NADH levels.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: How to avoid losing nutrients in fat thrown out from an organ meat blendI don't think you're going to lose that many nutrients because the 25% fat, 75% lean ground beef mixed with those organs, most of that fat is coming from the marbling of the beef. That's not coming from the organ meats. Most of the nutrients in the organ meats, and they're not in marbled fat they're in cells and stuff.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: How to manage the zinc-to-copper ratio?I don't agree with using the zinc/copper ratio in testing. So it is the case that zinc and copper need to be in a very loose range of ratios. So you don't want your dietary zinc to be more than 15 times your dietary copper, and you don't want your dietary zinc to be less than two times your dietary copper. But other than that, you're really looking at them individually, and you're looking at, do I have enough zinc? Do I have enough copper? Do I have signs of zinc deficiency? Do I have signs of copper deficiency? Do I have signs of too much of one or the other? Much more than you're looking at the ratio.

Question: Milk thistle, sulforaphane, and blood donation for iron overloadIf it's an uptrend, you probably want to do something about it. Someone in that situation could try the Nrf2 stimulators, like milk thistle and sulforaphane. But if it is a genuine uptrend in early stage iron overload, that might be a situation that giving blood once a year would be the best solution.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: Why would methylated vitamins increase pain sensitization?I'm not sure. Just to throw out some random threads that may or may not be of use. I think methylation in some people is going to lead to increased synthesis of dopamine. But in general, the effect is going to be to decrease the tonic pool of dopamine. There's going to be some degree to which it decreases other neuro-transmitters. And it's possible that if, particularly, if glycine is not stabilized, that you're going to lose the inhibitory effect of glycine and that you might also lose the effect of ambient glycine in coactivating NMDA receptors. Now off the top of my head, I would think that you would want the glycine there to support.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: Why would ferritin and B12 increase on a low-calorie keto diet?Ferritin is very strongly influenced by inflammation, oxidative stress. And so if the iron status is not changing and the ferritin is going up and then down, to me that suggests that oxidative stress or inflammation is increasing in the hypocaloric state. I was thinking maybe there's more PUFAs and stronger favoring of oxidative stress when there's more PUFAs released from adipose tissue during the hypercaloric during a hypocaloric state.  So, all the PUFAs are being metabolized in the liver. And so there's probably oxidative stress increasing in the liver specifically in the hypocaloric diet, because the fatty acids are all being biased towards lipolysis from adipose tissue straight to the liver for beta-oxidation. And I think that's dramatically increasing the oxidative burden on the liver and there's short term damage being done in the liver that's increasing the B12 and ferritin levels.

Question: Why are polyunsaturated fats more easily burned for energy than saturated fats?I don't know in detail the mechanism, but I do know that it's been shown in human cells and in live animal experiments. And it presumably is related to the affinity of the enzyme for the fatty acid. And that's not something that's biochemically difficult. It's normal if there are enzymes that work with any fatty acid, for them to have different affinities for some fatty acids versus others.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: Why zinc deficiency causes resistance to thyroid and sex hormones and vitamins A and DThe answer to that is because the, because all of those things carry out their gene expression function by binding to nuclear receptors. And all of the nuclear receptors to DNA using zinc finger motifs. Zinc finger motif means that in the nuclear receptor, there's a zinc ion that coordinates the primary structure of the protein, which is a long string of amino acids into a finger shape.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.
