How Carbohydrates and Not Protein Promote Aging

Denise Minger's different kinds of magic

.
I love her presentation!

Probably not true!

Who is a bastard who wrote "why"?

Magic rocks!   :)

I highly recommend to listen to her video. She is reviewing some old studies showing therapeutic effects of the very low fat high carbohydrate diets (VLFHC). Low fat means well below 10% preferably about 2%. When I begun my high fat low carb experiment back in 1999, which grew into my ongoing lifestyle nutrition to this day, I was aware that the very low fat natural food diet has been successfully used in halting progression of coronary heart disease and MS. I was familiar about Pritikin and Dr. Swank work. Prior to 1999 I was experimenting with vegetarian nutrition but I found it unpalatable, unless a sufficient amount of fat was added. More than 10%. So for me finding dr. Kwasniewski's Optimal Diet was a "gift from God", or I should say a gift from a friend of mine (Andrew S.)! Kwasniewski's Optimal Diet is high animal fat low carb diet (HFLC). After noticing back then that the VLFHC diets have some therapeutic property, I had many questions (i.e. "question everything"). One of them is about the long term viability and the side effects. Like with every therapy, there may be side effects. Are there side effects of VLFHC diets? How do people do on such nutrition scheme fare in the long term? Longevity issue? Longevity with a robust health or not so well? The same question can also be asked about any other diet, including the HFLC diet.

Unlike most other low carb promoters at that time (1970-ties - 1990-ties), dr. Kwasniewski did acknowledge that a high carbohydrate diet may also be healthy, quoting Japanese rice based diet as an example. He also insisted that, on such a diet (1) fat intake must be limited to abut 10% and (2) a sufficient amount of (lean) protein must be consumed. Insulin sensitivity is very high on such a diet because the intake of fat is very low but the pancreatic insulin secretion is medium. Insulin cannot be too low, due to carbohydrate-based metabolism. Typically it amounts to about 20-30 iu per day, based on my understanding and from reports by t1 diabetics (quoting from memory so verify this before you requote me!)

Dr. Kwasniewski also noticed, based on his patients record, that a particular proportion of macronutrients, consisting of about 35-45% of fat (by calories) and about 45-35% of carbohydrates is particulary unhealthy and makes people prone to developing diabetes and atherosclerotic heart disease. Kwasniewski also noticed that it causes a peculiar form of neuro-degeneration for people in their 40-ties and 50-ties manifesting itself in form character disorder (psychopathy). He called that dietary zone "dangerous middle zone". Pancreatic insulin secretion has to be very high (typically 40-60 iu/day or more) on such a diet in order to overcome the insulin insensitivity induced by the high fat intake.

He also noticed that as soon as you up the total fat intake to above 50% of calories then these pathological effects gradually subside and the diet becomes healthy again, even therapeutically healthy. The widely popular diet he publicized in the 1980-ties, arrived at the macronutrient proportions P:F:C (Protein to Fat to Carbohydrates) in gram per day per 1kg of ideal body weight of 1:3-3.5:0.8 to 1:2-2.5:0.5 . This typically works out at way over 60% (typ about 85%) of fat by calories. Notice that fat has 9kcal/g, glucose 4.5kcal/g and protein 3.5kcal/g (or less if used anabolically). Interestingly, Kwasniewski also found that his patients with coronary heart disease begun reversing and recovering. So his patients with many autoimmune disease such as asthma, rheumatoid arthritis, MS, IBS, and other - also recovered on his diet! Even though the HFLC diet is the exact opposite of the VLFHC diet, it nevertheless produced surprisingly similar (if not greater) therapeutic effects! Notice that the insulin sensitivity (and the effect of fat upon it) becomes irrelevant due to very low intake of carbohydrates. Kwasniewski quoted insulin requirement at this point, to be about 6-10 iu/day. How did he measured it? By observing his type 1 diabetic patients!

What Denise Minger has done, is rediscovering and publicizing that fact that there are 2 dietary zones that have therapeutic properties, not just one diet!

What I would disagree with, is her presumption that the VLFHC diet would:

- "results in healthier gut microbiome long term"

There is not proof or comparison studies done for VLFHC vs HFLC on that, while there is enough reports indicating the long term gut flora deterioration among vegans (I would put refs to Dr. Stanley Bass and Dr. Gian-Cursio reports on Natural Hygienists).

- "may do best for ApoE4 carriers"

No proof either, other than high serum cholesterol which does not always translate to a health risk, except for people eating in the dangerous middle zone.

- "may be able to restore and heal glucose tolerance which does not happen on the high fat..."

This is not true based on my personal observation. Initially yes, HFLC diet did not restore my glucose tolerance, it only allowed my body to bypass the issue by not showering my body with the excess carbohydrates. Whenever I tried to eat a little bit more than 50g of carbohydrates in a day, I would inevitably come to regret it! Carb-headache and nausea. Beer was especially bad for me. However, after about 2 years I noticed that I was able to increase that limit and add more than previously and after about 6-7 years I noticed that my carbohydrates tolerance has been totally restored! For example I can now consume a high carb dinner if I have no other choice without any adverse side effects. I don't do it often, but it is nice to know that my metabolism has completely been restored. I suspect it has to do with the mitochondrial regeneration. It takes about 7 years to regrow and renew most of our muscular tissues from our stem cells. I also found it that initially I had to watch not only the total carbohydrates intake, but I also had to limit the overall caloric intake from fat as well. Initially the total limit was about 1800kcal. Believe it or not that is actually perfectly sufficient for an adult leading an active life on the high fat diet, without any problems (I was 43 in 1999 when I begun HFLC and I weigh 64k, 173cm height) It was as if my metabolic channels were impaired for both macronutrients, for carbs as well as for fat, except the metabolism of fat, being more effective, allowed me to live better and have more energy in spite of the limitations. Again, that restriction is no longer applicable and lifted itself after about 7 years.

Results

During 23,196 person-years of follow-up (median per person, 7.5 years), 1059 (34.3%) participants died. Compared to normal total cholesterol (<5.18 mmol/l), borderline-high (5.18-6.21 mmol/l) and high (≥6.22 mmol/l) total cholesterol were associated with a decreased risk of all-cause mortality, with the multiple-adjusted hazard ratio (95% confidence interval, CI) of 0.71 (0.61–0.83) and 0.68 (0.57–0.80), respectively (P for trend <0.001). The competing risk regression models revealed that the reduced all-cause mortality associated with high total cholesterol (≥6.22 mmol/l)) was mainly due to the reduced risk of non-cardiovascular mortality (hazard ratio = 0.67, 95% CI = 0.51-0.88). These associations were statistically evident only among individuals without use of cholesterol-lowering medications.

Conclusions

The inverse association between high total cholesterol and reduced all-cause mortality in older adults is primarily due to non-cardiovascular mortality, especially among those who are not treated with cholesterol-lowering medications.

Schizophrenia put into remission on keto diet

.

Chronic Schizophrenia Put Into Remission Without Medication/New research suggests ketogenic diet may play a role in treating schizophrenia.
by Chris Palmer, M.D., Apr 06, 2019

Quotes

An 82 year old woman with chronic paranoid schizophrenia since age 17

The first patient documented in the Schizophrenia Research article is a woman who spent nearly her whole life suffering chronic, treatment-resistant schizophrenia. For more than 50 years, she endured paranoia, disorganized speech, visual and auditory hallucinations. By the time she was 70, she was suicidal and had been hospitalized repeatedly for psychosis or suicide attempts. She had been treated with over ten different antipsychotic and mood stabilizing medications, including regular antipsychotic injections. None of them helped her symptoms. She was unable to care for herself and had a court-appointed guardian and home health services.

At the age of 70, weighing 330 pounds, she went to a medical weight loss clinic and was started on a ketogenic diet. Within two weeks of starting the diet, she reported a noticeable reduction not only in her weight but also her psychotic symptoms. Within several months, she started to feel so much better that she was able to stop taking her psychiatric medications while remaining on the diet. Over time, her mood stabilized, and her hallucinations and paranoia remitted completely. She was no longer suicidal. Her case was first reported in 2009.

Today, 12 years later, she has lost a total of 150 pounds and remains on the ketogenic diet. She takes no medications and remains symptom-free. She was able to regain her independence, no longer requiring the guardian and the home health care team. When I recently spoke with her, she recalled her decades of suffering and hopelessness, and said that since starting the diet, she has had a "new life," and is happy to be alive.

A 39 year old woman with schizophrenia for 20 years

The second patient described in the article is a thirty-nine year old woman who suffered from depression, anxiety, anorexia nervosa, hallucinations and paranoia since her teens. As patients sometimes do, she concealed her psychotic symptoms when she was initially treated for depression and anorexia. When she finally reported her psychotic symptoms later in her twenties, she was diagnosed with schizophrenia. For the next ten years, she was treated with 7 different antipsychotic medications—including clozapine (called the “gold standard antipsychotic medication”) - along with antidepressants and anti-anxiety medications. Nevertheless, she continued to have symptoms.

She was having chronic gastrointestinal problems, so she saw a doctor who recommended the ketogenic diet. Noticing some improvement of her symptoms and being frustrated with all of her psychiatric medications, she unwisely stopped taking all 14 of her medications “cold turkey.” This sent her into severe psychosis requiring an extended hospitalization. In the hospital, she was re-medicated with Haldol-decanoate (an injectable medication which had not worked for her previously) and she continued the ketogenic diet. Within a month on both Haldol and the ketogenic diet, she reported complete remission of her psychotic symptoms for the first time since she was 14. Over the following year, she slowly tapered off Haldol, and remained free of psychotic symptoms. Of note, she lost 70 pounds from the diet, which exacerbated her anorexia. She has since regained 30 of those pounds and maintains a healthy weight today. 5 years after starting the ketogenic diet, she is off all antipsychotic medications, remains on the diet, and is free of all psychotic symptoms. She has since finished graduate school and now works full time.

Interestingly, these aren’t the first reports of the ketogenic diet for schizophrenia
While inspiring, these two case reports join a growing body of evidence supporting the use of the ketogenic diet in the treatment of schizophrenia.

Schizophrenia in 1965

In 1965, ten women hospitalized with schizophrenia who were already receiving medications and electroconvulsive therapy (ECT or “shock therapy”) were also placed on the ketogenic diet for a month. The researchers reported that their symptoms improved after two weeks on the diet, but then returned back to their baseline level of symptoms after the diet was stopped.

Schizoaffective disorder in 2017

In 2017, I reported two other cases of schizoaffective disorder improving significantly on the ketogenic diet. Schizoaffective disorder is a diagnosis that includes both a mix of schizophrenia and a mood disorder, often bipolar disorder. One man and one woman, both in their 30’s, had suffered treatment-resistant schizoaffective disorder for years. On the diet, their symptoms were greatly improved, and they both lost significant amounts of weight. Off the diet, their symptoms returned.

Schizophrenia in Ecuador

In 2018, two Ecuadorian twins, one male and one female, diagnosed with schizophrenia since the ages of 14 and 18 were started on a 6-week trial of the ketogenic diet. This study had a psychiatrist rate each twin’s symptoms while being unaware of their diet status. Interestingly, only when the patients were compliant with the diet did their symptoms improve. They also both lost weight. When they stopped the diet at the end of the study, their symptoms returned to their baseline level.

Stan's comments: - who were the medical criminals who stopped their patients' treatment as the article described, in spite of the clear improvement and despite of no viable alternatives? Why there was no information published and made available over the years, to other patients suffering from this debilitating disease, and their families? It is very symptomatic of a very serious disease rotting the medical system from within, in all countries. What have the government departments in charge of public health policies done to make that treatment available? Why did the judicial system refrain from punishing the people involved in maintaining this information hidden or even actively discouraging it by denigrating all ketogenic diets, all high fat low carbohydrate diets publicly and in the media? Who were the people, and who financed those who campaigned in the media smearing Drs. Yudkin, Atkins, Bernstein and others and why did public prosecutors and politicians allowed that to continue?

"Impaired insulin signaling in unaffected siblings and patients with first episode psychosis", by Virginie-Anne Chouinard et al., Mol Psychiatry. 2018 Mar 9


Quote

Patients with psychotic disorders are at high risk for type 2 diabetes mellitus, and there is increasing evidence that patients display glucose metabolism abnormalities before significant antipsychotic medication exposure. In the present study, we examined insulin action by quantifying insulin sensitivity in first episode psychosis (FEP) patients and unaffected siblings, compared to healthy individuals, using a physiological-based model and comprehensive assessment battery. Twenty-two unaffected siblings, 18 FEP patients and 15 healthy unrelated controls were evaluated using a 2-hour oral glucose tolerance test (OGTT), with 7 samples of plasma glucose and serum insulin concentration measurements. Insulin sensitivity was quantified using the oral minimal model method. Lipid, leptin, free fatty acids and inflammatory marker levels were also measured. Anthropometric, nutrient and activity assessments were conducted; total body composition and fat distribution were determined using whole-body dual energy x-ray absorptiometry. Insulin sensitivity significantly differed among groups (F=6.01, P=0.004), with patients and siblings showing lower insulin sensitivity, compared to controls (P=0.006, and P=0.002, respectively).

Comment: Comparison between people diagnosed with psychiatric disorder and their sibling who were not diagnosed and therefore not affected by psychiatric drugs, showed the common underlying metabolic disorder involving insulin insensitivity and high risk of developing diabetes type 2.

"Psychosis and Symbiosis: Microbiome and Schizophrenia. Fascinating new research links the gut and brain in sickness and health.", by Emily Deans M.D., Posted Mar 31, 2019

Quote:

Those mice that received the transplants from schizophrenic patients had higher levels of glutamine in the serum and hippocampus, decreased glutamate in the hippocampus, and increased GABA in the hippocampus. These difference were localized to areas of the brain particularly rich in glutamate and its metabolites (i.e., the outer shell of the brain and the hippocampus). This means that a transplant of a different microbiome led to different GABA-glutamate-glutamine neurotransmission in mouse brains. Corresponding human brain areas are related to memory, neuron repair, and executive functioning, all significantly impacted in schizophrenia.

In addition, the schizophrenia microbiome recipient mice had different behaviors than the healthy control mice, with exaggerated startle response and increased activity.

Volume 222, 1 April 2019, Pages 125-132

Quote:

Main methods

In this study, we used human renal cortical epithelial (HRCE) cells. The anti-apoptotic effect of βOHB was evaluated using flow cytometry analysis. The expression of apoptosis-related proteins and HDACs was evaluated by western immunoblot.

Key findings

The results showed that βOHB significantly reduced cisplatin-induced apoptosis in HRCE cells. Furthermore, βOHB significantly reduced cisplatin-induced cleavage of caspase-3, acetylation of histone H3, and phosphorylation of AMP-activated kinase. This anti-apoptotic effect of βOHB was markedly attenuated by an inhibitor of HDAC4/5, and βOHB-mediated suppression of cleavage of caspase3 was significantly blocked by siRNA-induced gene silencing of HDAC5.

Significance

βOHB attenuates cisplatin-induced apoptosis by activation of HDAC5 in HRCE cells, suggesting that βOHB may be a new therapeutic agent for cisplatin nephropathy.

New cancer treatment with rosiglitazone+trametinib

Cancer Cells Transformed into Harmless Fat in Mouse Study, By Rachael Rettner, January 15, 2019

Quote:

Then, the researchers treated the mice with two drugs: rosiglitazone, which is used in people to treat type 2 diabetes, and trametinib, an anti-cancer drug that inhibits the growth and spread of cancer cells. (Rosiglitazone belongs to a class of drugs known as thiazolidinediones, which bind to receptors that are found mainly in fat tissue and that play a role in a number of biological processes, including the formation of mature fat cells, according to a 2005 paper on the topic. People with diabetes are given the drug because the receptors that it binds to also help increase sensitivity to the hormone insulin, which is involved in regulating blood sugar levels.) The researchers in the new study found that when mice received this drug combination, the cancer cells that had broken free from the initial tumor (called "invasive cancer" cells) changed into fat cells. The drugs also suppressed the growth of the tumor and prevented further metastasis.

"Let’s do follow the climate money!", by Paul Driessen, December 30, 2018


Quotes:

* Federal funding for climate change research, technology, international assistance, and adaptation has increased from $2.4 billion in 1993 to $11.6 billion in 2014, with an additional $26.1 billion for climate change programs and activities provided by the 2009 American Recovery and Reinvestment Act.

* The Feds spent an estimated $150 billion on climate change and green energy subsidies during President Obama’s first term.

* That didn’t include the 30% tax credits/subsidies for wind and solar power: $8 billion to $10 billion a year – plus billions more from state programs that require utilities to buy expensive “green” energy.

* Worldwide, according to the “progressive” Climate Policy Initiative, climate change “investment” in 2013 totaled $359 billion – but this “falls far short” of the $5 trillion per year that’s actually needed.

The UN’s Intergovernmental Panel on Climate Change echoes those greedy demands. It says the world must spend $2.4 trillion per year for the next 17 years to subsidize the transition to renewable energy.

Bear in mind that $1.5 trillion per year was already being spent in 2014 on Climate Crisis, Inc. research, consulting, carbon trading and renewable projects, according to the Climate Change Business Journal. With 6-8% annual growth, we’re easily looking at a $2-trillion-per-year climate industry by now.

Mechanism behind omega-6 seed oil triggering autoimmune diseases

.

Summary. The study proved the following mechanism on mice may be triggering diseases such as muscular dystrophy, rheumatoid arthritis, atherosclerosis and lupus:

1. Dietary omega-6 seed oils produces NHE,

2. NHE binds to aminoacids from the DNA, then

3. immune system reacts against that and produces antibodies against NHA and against the DNA

4. immune system attacks and destroys body's own DNA and the cells die!

First read this, to understand what NHE is:
4-Hydroxynonenal (NHE)

Specifically:

Quote:

4-Hydroxynonenal is generated in the oxidation of lipids containing polyunsaturated omega-6 acyl groups, such as arachidonic or linoleic groups,
...
Special attention must also be paid to cooking oils used repeatedly in caterings and households, because in those processes very high amounts of OαβUAs are generated and they can be easily absorbed through the diet.

AN ENDOGENOUS TRIGGERING ANTIGEN OF ANTI-DNA RESPONSE", by Kazuyo Toyoda et al.,

Quote:

Abstract

Several lines of evidence indicate that the nonenzymatic oxidative modification of proteins and the subsequent accumulation of the modified proteins have been found in cells during aging and oxidative stress and in various pathological states, including premature diseases, muscular dystrophy, rheumatoid arthritis, and atherosclerosis. Our previous work suggested the existence of molecular mimicry between antibodies raised against hydroxy-2-nonenal (HNE)-modified protein and anti-DNA autoantibodies, a serologic hallmark of systemic lupus erythematosus (SLE). In the present study, we investigated the possible involvement of HNE-modified proteins as the endogenous source of the anti-DNA antibodies.

...

4-Hydroxy-2-nonenal (HNE), one of the most prominent lipid peroxidation-specific aldehydes, is believed to be largely responsible for the cytopathological effects observed during oxidative stress (4, 5). HNE exerts these effects because of its facile reactivity with biological materials, including proteins (Fig. 1) (5). Upon reaction of the protein, HNE specifically reacts with nucleophilic amino acids, such as cysteine, histidine, and lysine, to form stable Michael addition adducts possessing the cyclic hemiacetal structure (5). Previously, we raised the anti-HNE monoclonal antibodies (mAbs), which enantios-electively recognized the (R)-HNE-histidine Michael adducts (11), and unexpectedly found that the sequence of an anti-HNE mAb was highly homologous to the anti-DNA autoantibodies (12). In addition, we characterized the ability of the mAb to recognize DNA and identified the 4-Oxo-2-nonenal (ONE)-modified 2′-deoxynucleoside (7-(2-oxo-heptyl)-substituted 1,N2-etheno-type 4-oxo-2-nonenal-2′-deoxynucleoside) as an alternative epitope. Based on these findings, we proposed the hypothesis that post-translational protein modification with lipid peroxidation products, such as HNE, could serve as an immunological trigger for the production of anti-DNA autoantibodies in autoimmune diseases.

...We evaluated the effects of a combination of vitamin C (1000 mg/day) and vitamin E (400 IU/day) on insulin sensitivity as measured by glucose infusion rates (GIR) during a hyperinsulinemic, euglycemic clamp in previously untrained (n = 19) and pretrained (n = 20) healthy young men. Before and after a 4 week intervention of physical exercise, GIR was determined, and muscle biopsies for gene expression analyses as well as plasma samples were obtained to compare changes over baseline and potential influences of vitamins on exercise effects.

Consistent with the concept of mitohormesis, exercise-induced oxidative stress ameliorates insulin resistance and causes an adaptive response promoting endogenous antioxidant defense capacity. Supplementation with antioxidants may preclude these health-promoting effects of exercise in humans.

Mitochondrial DNA inherited from both parents!

Paper: "Biparental Inheritance of Mitochondrial DNA in Humans", by
Shiyu Luo, et al., PNAS, November 26, 2018


Quote:

The energy-producing organelle mitochondrion contains its own compact genome, which is separate from the nuclear genome. In nearly all mammals, this mitochondrial genome is inherited exclusively from the mother, and transmission of paternal mitochondria or mitochondrial DNA (mtDNA) has not been convincingly demonstrated in humans. In this paper, we have uncovered multiple instances of biparental inheritance of mtDNA spanning three unrelated multiple generation families, a result confirmed by independent sequencing across multiple unrelated laboratories with different methodologies. Surprisingly, this pattern of inheritance appears to be determined in an autosomal dominantlike manner. This paper profoundly alters a widespread belief about mitochondrial inheritance and potentially opens a novel field in mitochondrial medicine.

Note: they used lean read meat. I predict a follow-up study titled "A Mediterranean-style eating pattern with fatty, unprocessed red meat has the greatest cardiometabolic benefits"!

Results
Compared with the LF intervention, the MedDairy intervention resulted in a significantly lower morning SBP (mean difference: −1.6 mm Hg; 95% CI: −2.8, −0.4 mm Hg; P = 0.01), lower morning diastolic blood pressure (mean difference: −1.0; 95% CI: −1.7, −0.2 mm Hg; P = 0.01) and clinic SBP (mean difference: −3.5 mm Hg; 95% CI: −6.4, −0.7 mm Hg; P = 0.02), significantly higher HDL cholesterol (mean difference: 0.04 mmol/L; 95% CI: 0.01, 0.06 mmol/L; P < 0.01), lower triglycerides (mean difference: = −0.05 mmol/L; 95% CI: −0.08, −0.01 mmol/L; P < 0.01), and lower ratio of total to HDL cholesterol (mean difference: −0.4; 95% CI: −0.6, −0.2; P < 0.001). No effects were observed for other outcome measures. Conclusions
Following a MedDiet with additional dairy foods led to significant changes in markers of cardiovascular risk over 8 wk. The MedDiet supplemented with dairy may be appropriate for an improvement in cardiovascular risk factors in a population at risk of CVD.

The consumption of ground (wholemeal) wheat, compared with white wheat, was not associated with a significant reduction in blood glucose AUC [Area Under Curve] (−6.7 mmol/L ⋅ min; 95% CI: −25.1, 11.7 mmol/L ⋅ min; P = 0.477). The consumption of wholemeal rye, compared with endosperm rye, was not associated with a significant reduction in blood glucose AUC (−5.5 mmol/L ⋅ min; 95% CI: −24.8, 13.8 mmol/L ⋅ min; P = 0.576). ...

Note: there was some reduction in blood glucose spike (area under curve) following a meal with whole-grain rice versus white rice!
