"Thursday, 17 December 2009 This blog is in response to Dr Briffa's post here. as I keep having problems commenting on his blogs. While 44ng/ml is sufficient to not only maximize uptake of calcium (>32ng/ml) and ensure maximum bone mineral density (>42ng/ml), pregnant and nursing mothers should be aware that in order to maximize the amount of vitamin D3 in human breast milk 6400iu/daily was found to be necessary to raise (>58ng/ml) at latitude 32. This is detailed in the Taylor, Wagner and Hollis paper. Vitamin D supplementation during lactation to support infant and mother. Although 4000iu/daily met the mothers daily needs in full it left babies being born with lower 25(OH)D status than required for optimum calcium absorption They also found DAILY use of supplements was required by pregnant and nursing mothers to ensure an even daily Vitamin D3 supply to the foetus & baby. It makes virtually no measurable difference for everyone else if you supplement daily or weekly. While Dr Briffa will not be lactating he may be interested seeing in the Grassrootshealth chart showing disease incidence by 25(OH)D status. this may encourage him to go just another 10ng/ml higher and a bit nearer to the natural level at which human breast milk flows replete with D3."

Optimal serum 25-hydroxyvitamin D levels for multiple health outcomes. Bischoff-Ferrari HA. Adv Exp Med Biol. 2008;624:55-71. Review. PMID: 18348447 DOI: 10.1007/978-0-387-77574-6_5 Recent evidence suggests that higher vitamin D intakes beyond current recommendations may be associated with better health outcomes. In this chapter, evidence is summarized from different studies that evaluate threshold levels for serum 25(OH)D levels in relation to bone mineral density (BMD), lower extremity function, dental health, risk of falls, admission to nursing home, fractures, cancer prevention and incident hypertension. For all endpoints, the most advantageous serum levels for 25(OH)D appeared to be at least 75 nmol/l (30 ng/ml) and for cancer prevention, desirable 25(OH)D levels are between 90-120 nmol/l (36-48 ng/ml). An intake of no less than 1000IU (25 meg) of vitamin D3 (cholecalciferol) per day for all adults may bring at least 50% of the population up to 75 nmol/l. Thus, higher doses of vitamin D are needed to bring most individuals into the desired range. While estimates suggest that 2000 IU vitamin D3 per day may successfully and safely achieve this goal, the implications of 2000 IU or higher doses for the total adult population need to be addressed in future studies.

Serum vitamin D and risk of prostate cancer in a case-control analysis nested within the European Prospective Investigation into Cancer and Nutrition (EPIC). Travis RC, Crowe FL, Allen NE, Appleby PN, Roddam AW, Tjønneland A, Olsen A, Linseisen J, Kaaks R, Boeing H, Kröger J, Trichopoulou A, Dilis V, Trichopoulos D, Vineis P, Palli D, Tumino R, Sieri S, Bueno-de-Mesquita HB, van Duijnhoven FJ, Chirlaque MD, Barricarte A, Larrañaga N, González CA, Argüelles MV, Sánchez MJ, Stattin P, Hallmans G, Khaw KT, Bingham S, Rinaldi S, Slimani N, Jenab M, Riboli E, Key TJ. Am J Epidemiol. 2009 May 15;169(10):1223-32. Epub 2009 Apr 9. PMID: 19359375 In summary, the results of this large nested case-control study provide no evidence in support of a protective effect of circulating concentrations of vitamin D on the risk of prostate cancer.

Plasma vitamin D and 25OHD responses of young and old men to supplementation with vitamin D3. Harris SS, Dawson-Hughes B. J Am Coll Nutr. 2002 Aug;21(4):357-62. PMID: 12166534 Conclusions: There appears to be no age-related impairment among men in the absorption or metabolism of 20 µg/day of vitamin D3 taken orally for at least eight weeks.

Vitamin D for cancer prevention: global perspective. Garland CF, Gorham ED, Mohr SB, Garland FC. Ann Epidemiol. 2009 Jul;19(7):468-83. Review. PMID: 19523595 RESULTS/CONCLUSIONS: It is projected that raising the minimum year-around serum 25(OH)D level to 40 to 60 ng/mL (100-150 nmol/L) would prevent approximately 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer each year, and three fourths of deaths from these diseases in the United States and Canada, based on observational studies combined with a randomized trial. Such intakes also are expected to reduce case-fatality rates of patients who have breast, colorectal, or prostate cancer by half. There are no unreasonable risks from intake of 2000 IU per day of vitamin D(3), or from a population serum 25(OH)D level of 40 to 60 ng/mL. The time has arrived for nationally coordinated action to substantially increase intake of vitamin D and calcium.

"In a prospective study involving 6,937 men and women, higher levels of vitamin D were associated with a significantly lower risk of lung cancer in women and younger participants. During a maximum follow-up of 24 years, 122 cases of lung cancer were identified. After adjusting for potential confounders, higher serum 25-hydroxyvitamin D levels were associated with reduced risk of lung cancer risk in women (84% reduced risk) and younger participants (66% reduced risk). No association was observed between vitamin D status and lung cancer risk in men and older participants. "

"Study finds inadequate levels of Vitamin D may significantly increase risk of stroke, heart disease and death MURRAY, UT - While mothers have known that feeding their kids milk builds strong bones, a new study by researchers at the Heart Institute at Intermountain Medical Center in Salt Lake City suggests that Vitamin D contributes to a strong and healthy heart as well - and that inadequate levels of the vitamin may significantly increase a person's risk of stroke, heart disease, and death, even among people who've never had heart disease. For more than a year, the Intermountain Medical Center research team followed 27,686 patients who were 50 years of age or older with no prior history of cardiovascular disease. The participants had their blood Vitamin D levels tested during routine clinical care. The patients were divided into three groups based on their Vitamin D levels - normal (over 30 nanograms per milliliter), low (15-30 ng/ml), or very low (less than 15 ng/ml). The patients were then followed to see if they developed some form of heart disease."

"In 1995 my son received the devastating diagnosis of MS. Having been a research scientist for 30 years, I decided to plunge into the scientific literature for MS to determine the most likely factors which cause MS and to use this information to develop an effective therapy for my son. Notably, many people are having great success in halting or greatly slowing MS with nutritional strategies; many Testimonials are available. I am most pleased to report that my son remains in excellent health with no MS symptoms. I discovered abundant scientific evidence that indicates that various nutritional factors potentially play major roles in the onset and progression of MS. Strangely, this information was not being made available to persons with MS by doctors nor by established MS charities."

"(NaturalNews) Treatment with vitamin D supplements may slow the progress of , according to a study published in the journal BJU International. In the United States, prostate cancer is the second leading cause of cancer death among men, after lung cancer. Approximately 240,000 new cases are diagnosed every year, leading to 30,000 deaths. Researchers have suspected for nearly two decades that the so-called "sunshine vitamin" may play a role in the risk and progression of prostate cancer, but no studies have previously been conducted on its usefulness as a treatment."

Induction of ovarian cancer cell apoptosis by 1,25-dihydroxyvitamin D3 through the down-regulation of telomerase. Jiang F, Bao J, Li P, Nicosia SV, Bai W. J Biol Chem. 2004 Dec 17;279(51):53213-21. Epub 2004 Oct 12. PMID: 15485861 doi: 10.1074/jbc.M410395200 Overall, the study suggests that the down-regulation of telomerase activity by 1,25(OH)2VD3 and the resulting cell death are important components of the response of OCa cells to 1,25(OH)2VD3-induced growth suppression. Progressive shortening of telomere associated with cell divisions limits the life span of normal cells and eventually leads to senescence. To become immortal, human cancers including OCa are invariably associated with activation of mechanism that maintains telomere length. Approximately 85-90% of cancers show reactivation of telomerase. The present study shows that telomerase in OCa cells is down-regulated by 1,25(OH)2VD3. Down-regulation of telomerase is due to decreased stability of hTERT mRNA rather than VDRE-mediated transcriptional repression through the putative VDRE present in the regulatory region of the hTERT gene. It is known that the inhibition of telomerase may lead to a phenotypic lag during which cells would continue to divide until the point at which the telomeres became critically short. This phenomenon may explain why the apoptotic induction by 1,25(OH)2VD3 needs the treatment for more than 6 days. As mentioned in the results, no detectable shortening of telomeric repeats was observed in parental OVCAR3 cells after 9 days of treatment with 1,25(OH)2VD3 (Fig. 4D). This is likely due to the fact that the short telomere (about 3 kb) in OVCAR3 cells is very close to the minimal length required for survival and that cells with detectably shorter telomere may have been selected against apoptosis. It has been shown that transformed human cells enter crisis once the terminal restriction fragment of the telomere reaches a length of about 4 kb. This is insufficient to protect chro

"For more than 80 years, scientists have known that vitamin D is important for building bones. And for most of those 80 years, people thought this was the only thing it was good for. In the past decade, however, we've learned two important things about vitamin D: it appears to have many other important health effects, and many Americans don't get enough of it. In 2008, new research pointed to a vitamin D deficiency as a possible contributing factor in heart disease. And the suspected link between vitamin D deficiency and cancer grew even stronger. This surely will spur much new research in 2009. Why is vitamin D deficiency so common? The vitamin is made in our skin when sunlight strikes it. Many Americans-especially those who live in the northern part of the country, are elderly or have dark skin-don't soak up enough sun. And the vitamin isn't found in many foods. The main sources are fatty fish (such as salmon, mackerel, herring and sardines) and milk, cereal and juices that have been fortified with it. Vitamin D deficiency often is unsuspected because it causes no direct symptoms; like high blood pressure, it does its damage silently."

When it comes to health of your eyes, there is very little we do every day for them. No workout, no exercises and that too above the onslaught of staring at laptops and books all the time. While staring at your laptop is indispensable, you can get back your eye health with changes in your eating pattern based on nutritive value of foods.

About This Site Internet searches trawl up vast amounts of information about cancer, from a broad spectrum of viewpoints. The information and internet links on this site are for those seeking to augment the treatment offered by their hospital oncology (cancer) unit. Of course, a great many other internet sites concerning cancer can be found by keying the requisite search words into any of the major search engines. The content of this site was initially prepared, at the request of medical and nursing staff and others, some weeks after I had had an emergency operation for the removal of a colon cancer, and while undergoing chemotherapy in case any cancer cells had gone AWOL. There had been some escape of cancer cells into associated lymph nodes (3 out of 17, including the most distal), but no other tumours had been picked up by a CT scan. When I returned home from hospital in September 2005, with the help of friends, I started doing some research on cancer. I was amazed to discover that despite the billions of pounds/euros/dollars etc. spent on cancer research, and the many advances in understanding the numerous variants of the disease, the standard treatment for my stage of colon cancer is still a drug (fluorouracil, also called 5FU) that has been in use for more than forty years, has uncomfortable side effects, and which only increases the chances of survival after five years by 5 to 10%.

Vitamin D: a D-Lightful health perspective. Holick MF. Nutr Rev. 2008 Oct;66(10 Suppl 2):S182-94. Review. PMID: 18844847 DOI: 10.1111/j.1753-4887.2008.00104.x Sunlight provides most humans with their vitamin D requirement. Adequate vitamin D(3) by synthesis in the skin or from dietary and supplemental sources is essential for bone health throughout life. Vitamin D deficiency is defined as a 25(OH)D concentration 30 ng/mL (75 nmol/L), and insufficiency as 21-29 ng/mL. Vitamin D deficiency and insufficiency has been linked to a wide variety of chronic diseases including common cancers, autoimmune, cardiovascular, and infectious diseases. Healthcare professionals need to be aware of the vitamin D deficiency pandemic. Guidelines for sensible sun exposure and supplemental vitamin D of 800-1000 IU/day are needed.
