Vitamin K2 (MK 7) as a strong inhibitor of coronary artery calcification (CAC), I believe, is a contemporary issue. Heart disease is the #1 case of death in the US.

*Main dietary sources of vitamin K2 are: fermented soybeans called natto, grass fed butter, eggs, organ meats and cheese.

*BMC Nephrology, Mabel Aoun, et al., “High Dephosphorylated-Uncarboxylated MGP in Hemodialysis patients: risk factors and response to vitamin K2, A pre-post intervention clinical trial”, BMC series – open, inclusive and trusted, 2017, 18:191 DOI: 10.1186/s12882-017-0609-3

* Studies have shown populations with higher vitamin K2 intake (>32 mcg) have a 50% reduction in death risk from CVD compared to those with low intake (J Nutr., 134(11), 2004, Integr Med {Encinitas}, 14(1), 2015)

There is a growing debate over the validity and value of data derived from memory-based dietary assessment methods (M-BMs) such as FFQs, food diaries, and 24HRs. My empirically supported position is that all forms of M-BMs are pseudo-scientific, produce non-falsifiable and physiologically implausible data, and should not be used in nutrition research. Please see the recent 'Controversy & Debate' Series in the Journal of Clinical Epidemiology for details: Archer E, Marlow ML, Lavie CJ. The Fatal Flaws of Food Frequency Questionnaires and Other Memory-Based Dietary Assessment Methods. Journal of Clinical Epidemiology. 2018.

Hi Catherine

Thanks for the links. Some very good papers there.

Terun

 Thank you for all the information, Matej. I appreciate your concern for this. Network for Excellence in Health Innovation seems very important.  Research companies also share that MH facilities mostly do not survey for consumer satisfaction and effectiveness. This is all a terrible shame, and we should continue advocating for these causes.

Many Thanks

Callisthenics is a good form of exercises that helps to stimulate lean muscle growth, results can be moderately rapid if put in combination with a healthy diet and sufficient sleep, as it allows the body to recover.

The answer appears to be yes.  Researchers found Candida yeast in the brains of 11 AD who diet but not in the brains of those who died of other causes. (Pisa D et al. Scientific Reports, 5, 2015). 

AB proteins thought to cause AD but now found to block the growth of C. albicans & other brain infections.  Therefore, AB is a symptom--not the cause of AD.

Dr. Mark Stengler (Health Revelations 2016) recommends a low glycemic diet, protein, vegetables, pre/probiotic food & multi-strain PBs, S. Boulardii  (and antifungal drugs when needed) to help eradicate and keep low C. albicans--therefore preventing the buildup of AB.

Salut Thierry,

Je suis vraiment désolé d'apprendre cette nouvelle. Il y a deux livres phares sur ce sujet: Le Vrai Régime anticancer, par Prof David Khayat, et Anticancer, de David Servan Schreiber.  Je pense que celui de Khayat est le plus "scientifique", mais l'autre est considéré comme remarquable aussi.  Bonne chance à ta fille (et à vous). D'après ce que je sais, les cancers du cerveau de l'enfant ont un bon pronostic.  Si je peux être d'une quelconque utilité n'hésite pas!

Amicalement

Dan

Yes, there could be multiple relationships. I have more clinical experience on this than direct personal research knowledge, however. Consider the research on how belief in the efficacy (or lack thereof) of a psychotropic medication, e.g. antidepressant, will predict ultimate therapeutic response.  People may believe that specific foods or dietary 'recipes' are therapeutic (or harmful).  Weight Locus of Control will be affected by these beliefs. So if a person thinks that high fructose corn syrup or 'bad bacteria' will take over their metabolism and redirect their adiposity (ie make them gain weight), they may feel helpless and become avoidant, perhaps phobic about 'dangerous' foods. The opposite or inverted concept may also operate:  If a person's Weight Locus of Control resides 'within' them and they perceive a sense of mastery over their environment, the have a high internal control, ie realization that they have the income and access capacities to acquire quality foods.  Alternatively, a person may have a external locus of control: 'i am poor, living in a rural or 'urban desert' where quality food is inaccessible. People living 60+ miles from grocery stores with fresh food, who do not have the means to grow their own food, may rationalize a high BMI and have a low WLOC.

Dear Awarm

As you can see bu the previous responses, there are different algorythms in the literature for the estimation of body weight. I would look at different options and try the ones that would be more suited for my population, and then look at the ones with the highest R2 and lowest standard errors  (SRMSE) of the predictive regression equations.. I think the patients preception of their own weight, as mentioned above is also a very good idea.

As you might be intersted in prediction of standing height as well, I include a recent publication from our group on the estimation of height based on knee length

Hope this is useful

A balance diet is definitely the key. Usually for diabetes, you would want to also include low glycemic index food, such as fiber, to prevent postprandial glucose spike. 

I'm a supporter of plant-based diets, but Campbell's "China Study" is full of methodological errors and therfore of low scientific value. Take a look at this: http://rawfoodsos.com/the-china-study/

However, there are some evidences that link dairy products with breast and prostata cancer:

1) Qin LQ, Xu JY, Wang PY, Kaneko T, Hoshi K, Sato A. Milk consumption is a risk factor for prostate cancer: meta-analysis of case-control studies. Nutr Cancer. 2009;48(1):22–27

2) Dong JY, Zhang L, He K, Qin LQ. Dairy consumption and risk of breast cancer: a meta-analysis of prospective cohort studies. Breast Cancer Res Treat. 2011;127(1):23–31

I think  it may happen under conditions when the animal is mobilizing all its reserves to  keep its metabolic processes go on.

According to me, to be a vegetarian is rather than a living attitude than a scientific way. You are a vegetarian if you does not eat meat and meat products from breeding animals. Protozoans are not slaughtered and they don't eat corn or wheat, as competitors from vegetal sources for human nutrition. Good luck. JB

In a randomized, double-blind, placebo-controlled clinical trial in 2011, conducted at Bastyr University Research Institute, Kenmore, WA and the Bastyr Center for Natural Health, Seattle, WA, reported that  short-term, oral intake (500 mg twice daily administered  to  volunteers for 4 weeks) GSH does not improve glutathione status or reduce markers of oxidative stress in healthy adults.  The authors indicated that routine supplementation might not offer health benefits in the absence of disease or oxidative challenge.

Thank you Michael. I am still interested in working on projects regarding food labeling and consumer behavior/attitudes. 

Hi Dave then I guess you research question is very valid then, now i see its application a little better. I think if you lack ALH's then adaptation is the only way forward, you can only work with whom you have or what you've got. Good luck in your research David nice talking with you by the way.

Emely -

By "foreigners', do you mean immigrants?  The years of residence in the "new" country would be a major issue because dietary habits change over time. Lifestyle factors and overnutrition warrant attention. (Specially when not only the country of origin has a very different culture and diet pattern, but also, different groups of immigrants from various countries coexist.> So it is a heterogeneous group, and therefore ethnic actors are not an issue. How can you study the issue when individuals are not from  a single group?

One of the problems I find is that when you conceptualize the "behavior" of eating a meal - it can be thought of as a series of responses such as any task - each step acts as a discriminative stimulus for the next step as well as reinforcing consequence for the previous step - inserting a "novel" step - such as taking a picture of your food is adding a step to a pretty practiced behavior (ie I take my food from the refrigerator - put on a plate - bring it to the table ...) typically I am not thinking about the process since it is so "rote" and often I find when I attempt to consistently photo post my meals - I will find myself already eating my meal before I remember to photo-post it first! In order not to forget - I would need a prompt - be a "alert" on my phone (assuming I always eat the same time. In terms of photo-posting to the investigator directly - that behavior may be reinforcing to some (a way of recruiting praise for making "good" food choices) and it also could be aversive (such as feeling bad if you not making an "optimal" choice - like eating a candy bar) and sometimes the extra response effort makes this level of self-monitoring less preferred to the alternative behavior of "doing nothing" (ie the status quo) - in other words - my informal research among those who have and continue to be members of my various FB groups is that there is huge surge of momentum at the beginning but as time goes on - the motivation to post wanes and so does access to social praise - so it is good to have other schedules of both reinforcement or maybe even a potential punisher (such as a response cost - like the website stickK.com)

Also in terms of running a baseline - I found that simply telling people the premise of the intervention - such as - investigating whether photo posting to a private FB group - has a sequencing effect in terms of introducing a confounding variable - "pure" baseline would be to literally have the investigator observe (without telling the participants) what they are eating - but not sure how that would adhere to "informed consent" - any level of self-awareness tends to alter people's behavior.

Dear Dick,

A class of drugs called proton pump inhibitors (PPIs) have become the most common medication used to suppress stomach acid production in people with reflux.

PPIs are believed to affect calcium metabolism by promoting accelerated loss of calcium from the bones in addition to impairing absorption of calcium from the diet. They have also been shown to impair absorption of magnesium, another mineral important to bone mineralization. PPIs can promote "hypermotility" of the gut , you may say that they can cause diarrhea in some users. Sometimes, this diarrhea can be misdiagnosed as IBS.they can cause food intolerances.

Thanks, very helpful

Many of the high impact sports medicine journals report on all kinds of instruments (tests) and surveys that can be used, some validated, hence useful for a population of athletes.

Thank you very much!. It sounds very interesting, I will look for the last studies on resveratrol.

Oh, that is very interesting and from Anand. Just today being Dr.Kurien's Birth anniversary and a reply from you really delights me. Thank you very much Mr.Jashbhai. Kindly do inform us for any field trials as well, since it is a nutritious product and there should be no objection from the subjects. Please do plan such a work. With regards, Saileela.
