Calcium shift: An interesting hypothesis.

More serendipity! Billy the k left a comment that piqued my curiosity.

From https://www.health-heart.org/acceuil.htm The atheroma 'junk' in the media is cholesterol + calcium in older people.

From Aging and calcium as an environmental factor. (emphasis mine)
"The consequences of calcium deficiency might thus include not only osteoporosis, but also arteriosclerosis and hypertension due to the increase of calcium in the vascular wall, amyotrophic lateral sclerosis and senile dementia due to calcium deposition in the central nervous system, and a decrease in cellular function, because of blunting of the difference in extracellular-intracellular calcium, leading to diabetes mellitus, immune deficiency and others.

I highlighted amyotrophic lateral sclerosis in red, as many Facebook friends have been having buckets of water & ice cubes tipped over themselves to raise money for research into this horrible & ultimately fatal condition.

So, what prevents & reverses migration of calcium from hard tissues to soft tissues?
Clue: It carboxylates osteocalcin in bone matrix Gla proteins. Yes, it's Vitamin K2.

See also Calcium, parathyroids and aging. N.B. 50iu/kg bodyweight/day of Vitamin D3 significantly lowers parathyroid hormone.

The danger of science denial: It happens even on Science-Based blogs.

Poor Benjamin Franklin. I know how he felt! ;-)

I do not believe that he wanted to be doing that!

This post will be highly critical of Dr. David Gorski MD, as some of his comments have been either trolling, downright stupid, or both. They're definitely in denial of science. This post is intended to encourage Dr Gorski to leave comments here, as I will never leave any further comments on any blogs that he edits, for reasons mentioned previously. I will be copying comments from his blogs and pasting them here, with my comments after. If this is considered to be "bad form", I really don't care. Leaving derogatory comments about me on blogs on which the commenters know that I will never return (because I told them so) is definitely "bad form".

I will also be quoting other commenters on Dr Gorski's blog, for the same reason. Everyone is free to leave comments here, that meet my fairly lax moderation criteria. In Vitamin D, cancer, cliques and flouncing. , a commenter from Dr Gorski's blog called flip was initially whitelisted, to allow his comments to appear without me having to moderate them. I eventually blacklisted flip after I detected intellectual dishonesty. That's how I roll. If you don't like my rules, don't let the door hit you on the way out! By the way, calling me a liar on here is a sure-fire way to get yourself blacklisted.

I've just turned Blogger word verification back on, as although Disqus automatically deletes anonymous comments containing links, I still get email notification of them. I've been getting a lot of email notifications. This may or may not have an effect on commenters.

Firstly, please read https://www.sciencebasedmedicine.org/index.php/a-closer-look-at-vitamin-injections/#comment-127850 , as it's my "letter of resignation" from that blog. With that in mind, read on.

Regarding Lappe et al, one notes that that study is not the be-all and end-all of vitamin D research. It’s an old study, for one thing. Also, cancer was not its primary endpoint. Finally, there was no vitamin D alone group, as I recall, only a vitamin D + calcium group, a calcium group, and a placebo group.
There is a recent review of the literature from the Endocrine Society, which includes Lappe et al and puts it into context:

How so? It’s actually very, very relevant, as is the issue of cancer not being a primary outcome measure of the study. That you don’t understand why these issues are so relevant indicates to me that you don’t understand clinical research very well.

1) The RCT used Ca + D. Therefore, the conclusions apply to Ca + D. If they’d wanted to test D alone, they would have. They didn’t. Why don’t you write a letter of complaint to Joan M Lappe about it?

2) Whether the outcome was primary, secondary, tertiary, quaternary or n’ary is irrelevant because the parameter in question (all-cancer diagnoses) was still accurately recorded. That you can’t understand such a simple concept boggles my imagination.

#David Gorski on 27 May 2013 at 2:34 pm

As I’m leaving permanently, what’s the point?

Ah, flouncing off again. It’s probably long overdue. I’ve been getting a few complaints about you here as well. Perhaps you should ask yourself why complaints seem to follow you wherever you go.

“Whether the outcome was primary, secondary, tertiary, quaternary or n’ary is irrelevant because the parameter in question (all-cancer diagnoses) was still accurately recorded. That you can’t understand such a simple concept boggles my imagination.”

I rest my case that you do not understand clinical trial methodology and interpretation. I couldn’t have demonstrated it better myself to anyone who actually does understand clinical trial methodology and interpretation. Thanks!

You sir, are an asshole. I spelled it the American way, just for you!

I rest my case that you're either trolling, or stupid, or both. Whether the outcome is primary, secondary, tertiary, quaternary or n’ary is completely and utterly irrelevant. It always has been and it always will be. You're effectively saying that only the first item in a shopping list should be bought because all of the other items in the shopping list are irrelevant. Bullshit!

@ Marc Stevens Is Insane:
I believe that Nigel is like two bright guys I know: they are well educated and professional in fields outside of SBM/ life sciences (business). Thus they read alt med ‘research’ (also see today’s post by Orac) and don’t get how it DOESN’T work in reality. It sounds like nutrients can do all of these wonderful things – that they can’t- at least not in RL. But the woo-meisters don’t tell you that part. We do.

So of course they think that these products are very useful- and they need celtic salt or ground organic flaxseed- as I know all too well.

However, if they’re smart- we can talk to them:
explaining how that *in vitro/ in vivo* thing works.
Or- as I often do- illustrating how much of the so-called science they read ( woo) is actually more accurately called “advertising copy”.

Businessmen seem to grok that.

Denice, seriously? I'm disappointed. I thought that you were one of the few reasonable posters on Gorski's blog and then you go and write that crap?

I do not read "alt med ‘research’", unless you're calling what's on PubMed "alt med ‘research’"? I've been reading studies on PubMed for years, so I know about the use of shoddy methodology to fudge results. The Lappe study doesn't use shoddy methodology. It's a Randomised Controlled Trial using double-blinded placebos and randomly-selected subjects who were post-menopausal women. Try to pick holes in it.

flip May 29, 2013
Hmmm… it occurs to me I probably haven’t been that overt about one other thing:

Lilady, I am sorry that you were called those things, and I certainly don’t think you should have been called names. I do think Nigel was wrong and do think he should be called out for it.

And I’m sorry for not making that clearer before.

flip, I'm not going to question your intelligence. However, why you're apologising to lilady boggles the imagination. lilady is a despicable human being. She pushed me to the point where I called her rude names, names that were not misogynist and for which I apologised. I explained about "twat" on SBM. I even posted a link to Wiktionary! You don't read things thoroughly before commenting.

Marc Stephens Is Insane May 31, 2013
Oooooh, Nigeepoo is ANGRY! He’s pulled a DJT, posting a “rebuttal” to all the comments here and on SBM. I’m suprised it’s taken him this long.

He’s calling Orac an a**hole and stupid, among other things. He’s invited us all to comment on his blog because he has an “open moderation policy” and “allows all comments.”

https://nigeepoo.blogspot.com.au/

I see that you idiots on RI are still reading my blog. I'm not the slightest bit angry, so you can give the projection crap a rest. For the record, most of you come across as assholes. You can't even quote me correctly. I said that I have fairly lax moderation criteria. Do try to get something right, for once in your miserable lives.

Anyway, you lot are now boring me with your never-ending inability to discuss things either accurately or rationally, so I'm not going to bother polluting my blog with any more of your crap.

P.S. I still occasionally read the comments on Gorski's blogs, so for the benefit of you peeps who read mine:-
1) "Black-list" means exactly what it says. It means that you're banned from posting comments.
2) The Lappe et al 2007 study was a good study. Just because some Messiah-like person says that it's a bad study and applies false reasoning to back himself up, doesn't make him right and me wrong. As I've previously pointed out, surgery's not exactly rocket science is it? I designed complicated electronic communications systems for 29 years. Just saying! ;-) Denice, I've got nothing against you. You've just been drinking Gorski's Kool-Aid for way too long. That's not a euphemism, by the way! :-D

Look what I just found. Exposing Dr. David H. Gorski, M.D., Ph.D. who believes he can use a cloak of anonymity and character assaults to discredit opposing views. Sorry Doc, but your game is up.

He's not the Messiah. He's a very naughty boy! :-D

Vitamin D, cancer, cliques and flouncing.

First Google Image Search result for Vitamin D, cancer, cliques and flouncing.

This is a continuation of my previous post Enzyme kinetics, standing on the sun and weird blog comments sections.

Apparently, I didn't like the answers that I received on the blog in my previous post, so I flounced. The study that I asked for opinion on was Vitamin D and calcium supplementation reduces cancer risk: results of a randomized trial. If I showed you an RCT where deaths from all cancers fell by 77%, what would be your reaction? My reaction would be "That looks promising. More work is needed to investigate it". One person (sophia8) reacted thusly. Other reactions that I received (with their logical fallacies) were as follows:-

Pure coincidence. Argumentum ad ignorantiam.

More than 1,100iu/day of Vitamin D is harmful. Straw man. I didn't say that people should take more than 1,100iu/day of Vitamin D (even though I take 5,000iu/day, which isn't harmful). Also, argumentum ad ignorantiam. See enzyme kinetics in the previous post.

You're cranky. Ignoratio Elenchi.

The study wasn't testing Vitamin D on its own. Straw man. I didn't say that it did.

By the way, “Nigeepoo”, taking supplemental vitamin D is not a proven way to prevent sunburn and is not an adequate method of protection from getting skin cancer (despite assertions in your blog). Straw man for the first part of the sentence. I didn't say that it was. Argumentum ad ignorantiam for the last part of the sentence.

Going for long drives with the top down and broiling gently without sunscreen on a repeated basis is dumb. Straw man. I didn't say that I did. I obviously don't go for long drives with the top down in the middle of the day on a sunny Summer's day. That is dumb. Like, duh!

I'm curious why you found my response to be satisfactory but lilady’s to be unsatisfactory. Could you explain? Ignoratio Elenchi.

Did I mention all of the mis-quoting?... Oy!

Maybe they should have done a bit of basic research, like:-

Vitamin D and musculoskeletal health, cardiovascular disease, autoimmunity and cancer: Recommendations for clinical practice.

The effect of calcium and vitamin D supplementation on obesity in postmenopausal women: secondary analysis for a large-scale, placebo controlled, double-blind, 4-year longitudinal clinical trial.

Vitamin D, cardiovascular disease and mortality.

Why randomized controlled trials of calcium and vitamin D sometimes fail. Essential reading.

I'm the sort of person who's not interested in cliques or secret societies. I'm therefore not interested in joining a cliquey, ivory-towery blog where you have to conform to a set of unwritten "rules" to be accepted, some of which are eccentric (Question: Which blogs insist on the use of manually-typed blockquote tags? Answer: Only that one). I decided to leave. I even apologised to some commenters for my language in some of the arguments.

I wondered why that blog and its owner annoyed me so much. Then it hit me (like a discarded boomerang)!

Hmmm. See Brain Surgeon meets Rocket Scientist ;-)

Nigel, you need to tone it down, too.

Thank you Orac for your intervention.
The bottom line for Nigel and Lisa is that they, by their vicious unwarranted personal attacks, have drawn unfavorable publicity to themselves and their blogs.

There's no such thing as unfavorable (sic) publicity for my blog, as far as I'm concerned. What you have done, by your vicious, unwarranted, lying and malicious defamatory personal attacks on me, is to draw unfavourable interest from me.

Cheapest Vitamin D3 yet.

A big thank you to Ted Hutchinson for bringing Vitamin D3 to my attention. Healthy Origins, Depot Vitamin D3, 125mcg (5,000IU) is very reasonably priced (£26.56 for 360 gelcaps which is a year's supply at 2026 prices).

How care homes are starving their residents to death.

Now that I have your full attention (!), care & nursing homes give their residents plenty to eat & drink, so they are not starving them to death in the conventional sense.

So, what am I talking about? Clue:- UVB cannot penetrate window glass.

I'm talking about Vitamin D starvation.

At this time of year, care home residents are dying like flies. My sister (who worked in a care home years ago) told me that this is normal. Three died at mum's care home in the same week recently. All of the residents have one thing in common. They're all pale.

Old people feel the cold, so if they do go outside between March and September, they're covered from head to toe in clothes. They synthesise minimal Vitamin D in their skins for their bodies to store. Then, between September and March, their bodies use up those stores. Vitamin D levels decay exponentially , with a half-life of about 60 days. As Vitamin D levels fall, the risk of getting viral infections greatly increases, mood worsens, aches and pains worsen, blood glucose control worsens, the risk of getting cancer greatly increases. Need I go on?

As Dr. Richard M. Cooper (Private GP, Harley Street) pointed out, ALL of his patients were low in Vitamin D and they were active people who could go outdoors. Many care home residents can't go outdoors. They can get a paltry 400iu Vitamin D from an Adcal-D3 chewable tablet, but they're huge things that taste like sweetened chalk and cause constipation (mum hated them).

Death by Vitamin D starvation is a long, drawn-out process that reduces the quality & length of life for care home residents. Something needs to be done about it. All care home residents should have their serum Vitamin D levels tested and be given Vitamin D3 accordingly. I have broached this subject with the manager of mum's care home.

Mum's on 5,000iu/day of Vitamin D3. Although she is now fairly non compos mentis, she still smiles a lot and laughs at my dreadful jokes. She is also infection-free.

Here's the transcript of a YouTube video that's since been removed.
"At this care home, they're proud of their varied menu. Even so, the Government recommends supplements for the over 65's as well as children under 3 and women who are pregnant or breast-feeding. But health charities are demanding clearer guidelines and better advice. Because research into Vitamin D deficiency has revealed associations with all sorts of conditions, including Multiple Sclerosis, Diabetes, Arthritis, Osteoporosis, Heart Disease and even some cancers."

Dr Carrie Ruxton (Award-winning dietitian and health writer. Media commentator on diet, food and nutrition issues. Advisor to the food industry and government) said:-
"What I think the Government should do is promote its own policies. It had a policy for years to recommend Vitamin D supplementation for vulnerable groups, like elderly, housebound and pregnant & lactating women and children but at the moment, that's not being done. In my own example, I was pregnant twice and nobody told me to take Vitamin D supplements."

This is unacceptable. As the manager at mum's care home is not responsible for the residents' supplementation, I will be taking this up with the MP for the area.

Update: I spoke to the nurse on Friday 2nd March about mum's medical history. Before Vitamin D3, mum had a Urinary Tract Infection in the previous 9 months. Since Vitamin D3, mum has had no medical problems and she has been happy & contented. Her serum Vitamin D level is in the normal range.

Phew! That's a bit more than I expected.

If you fancy doing a search yourself, click on PubMed.

Why exercise may or may not help you to lose weight.

Exercise. I hate it! I'm about as active as a Brazilian 2-toed Sloth. The problem that I had with exercise is that it made me hungry and I ended up eating more Calories than I burned by exercising. This was due to me doing it wrong! See Move More: Solutions to problems and Exercise decreases appetite.

The thing about exercise in moderation, is that it's good for health & fitness. The problem is that some people think that doing lots more is better. It ain't necessarily so. The 38 year old lady sitting near me at karaoke last night used to run a lot when she was at school. She now needs a replacement knee joint due to damaged cartilage and she had her knee wired up to a TENS machine. See A little moderate to vigorous physical activity does more than you think.

Too much early morning exercise can also make you ill, by raising serum cortisol level. High cortisol level is immunosuppressive. See Early morning exercise could make you ill. High cortisol level also causes water retention, so people who over-exercise can gain water weight. Chronically-high cortisol levels can also cause muscle loss, thin skin and osteoporosis.

Starving yourself and over-exercising makes things even worse. From WHY is the combination of high intensity and/or long duration activity a mistake when calories are being severely restricted?

"Water retention: cortisol binds to the mineralocorticoid receptor (the receptor involved in water retention, well one of them). And although cortisol has 1/100th of the effect on water balance of the primary hormones (aldosterone and a couple of others), since there is like 8000 times as much of it, it can cause a major effect."

"Excessive cortisol, especially chronic elevations cause other problems not the least of which is leptin resistance. Which only magnifies the drop in leptin from dieting. This could be another mechanism behind the greater drop in metabolic rate for the study I mentioned above."

So, what's the best thing to do for maximum fat loss with minimum muscle loss? A mixture of high-intensity exercise (resistance training with weights, or sprinting) and medium-intensity exercise (jogging) (a.k.a. High-Intensity Interval Training, or HIIT) is better than just medium-intensity exercise. See Resistance Weight Training With Endurance Training Enhances Fat Loss, Impact of Exercise Intensity on Body Fatness and Skeletal Muscle Metabolism and HIIT & Run.

One theory to try and explain the improved fat loss of HIIT is that Calories are burned after the high-intensity exercise is finished. However, the Excess Post-exercise Oxygen Consumption (EPOC) only amounts to ~35kcals, so it isn't significant. It's almost certainly the appetite-suppressive effect of exercise that makes you glow, that results in reduced Calories in.

Vitamin K(2)

From https://www.health-heart.org/acceuil.htm The atheroma 'junk' in the media is cholesterol + calcium in older people.

Vitamin K used to be thought of as only the blood clotting (Koagulation) vitamin, as the liver needs it in order to synthesise Factor X. Some new-borns need Vitamin K injections, to achieve proper blood clotting.

However, Vitamin K is also needed for the carboxylation of osteocalcin in Bone Matrix Gla Proteins (or something like that!). The what of what in what? In simple terms, Vitamin K is needed to ensure that dietary calcium goes into your bones, rather than into your artery walls, kidneys, nervous system, brain, pancreas, joints, tendons etc. A lack of Vitamin K can cause osteoporosis. To prevent/treat osteoporosis, either Vitamin K1 (phylloquinone) or Vitamin K2 (menaquinone or menatetrenone) will suffice. Only Vitamin K2 can result in the removal of calcium from the wrong places.

I used 15mg/day of Vitamin K2 (plus 750mg/day of Ca plus 400mg/day of Mg plus ~1,000iu/day of Vitamin D3) to reverse osteoporosis in my lumbar spine (bone density by DEXA went from -2SD to 0SD) in 3 years. I didn't take Fosamax, as it can damage the oesophagus & stomach if it's not 1) swallowed while standing up, 2) washed down with shed-loads of water & 3) staying vertical for 30 minutes. It also kills osteoclasts. My endocrinologist told me that what I did was impossible. The impossible, I can do. Miracles take a little longer! :-)

From The Rotterdam Study:-"The relative risk (RR) of CHD mortality was reduced in the upper tertile (~40.9ug/d) of dietary menaquinone (K2) compared to the lower tertile (~15.1ug/d), RR 0.43, 95% CI: 0.24, 0.77.
Phylloquinone (K1) intake was not related to any of the outcomes."

RR 0.43 means, on average, 57% reduction in heart attack deaths. I've now put K2 in Cholesterol & Coronary Heart Disease.

Vitamin K2 is required for blood glucose regulation. See Vitamin K₂ prevents hyperglycemia and cancellous osteopenia in rats with streptozotocin-induced type 1 diabetes.

Vitamin K2 is required for brain health. See Look after your brain.

Good food sources of Vitamin K2 can be found here.

Warfarin antagonises Vitamin K, so it can result in arterial calcification. Anyone taking warfarin should ask their GP for regular check-ups to keep an eye on this potential problem. Taking Vitamin K supplements makes warfarin ineffective.

As we age, arteries can harden, bones can soften and joints can become painfully calcified. See Calcium shift: An interesting hypothesis for an hypothesis explaining how this can happen, a list of other diseases caused by Calcium Shift, and how to prevent and/or reverse it (the answer's in this post!).

Speculations on vitamin K, VKORC1 genotype and autism.
"Recent research has documented the protective effect of Vitamin K on neural cells and its role in maintaining normal neural development. Of interest, specific neural effects of Vitamin K overlap with key brain development aberrations, including those associated with autism. Furthermore, Vitamin K protects against oxidative stress associated with toxic exposure."

"...a small sample of severely autistic children of Somali descent residing in the Minneapolis/St. Paul area of Minnesota were genotyped and found to have a higher than expected genetic substitution that results in reduction in the efficiency of the Vitamin K cycle."

NEW!  Current trends and recent advances in diagnosis, therapy, and prevention of hepatocellular carcinoma. Hepatocellular carcinoma (HCC) is Liver cancer.
"Sorafenib is currently the only approved systemic treatment for HCC."

"Interestingly, coffee and vitamin K2 have been proven to provide protective effects against HCC."
