Serum vitamin D concentration and prostate cancer risk: a nested case-control study. Ahn J, Peters U, Albanes D, Purdue MP, Abnet CC, Chatterjee N, Horst RL, Hollis BW, Huang WY, Shikany JM, Hayes RB; Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial Project Team. J Natl Cancer Inst. 2008 Jun 4;100(11):796-804. Epub 2008 May 27. PMID: 18505967 doi:10.1093/jnci/djn152 CONCLUSION: The findings of this large prospective study do not support the hypothesis that vitamin D is associated with decreased risk of prostate cancer; indeed, higher circulating 25(OH)D concentrations may be associated with increased risk of aggressive disease. In summary, results from this large prospective study of men who underwent standardized prostate cancer screening in the context of a screening trial do not support the hypothesis that higher serum vitamin D status is associated with decreased risk of prostate cancer. The study showed no association of vitamin D level with nonaggressive disease; however, it raises the possibility that higher vitamin D level may be associated with increased risks for aggressive disease, although a clear monotonic dose-response relationship was lacking. Along with recent reports of adverse associations for higher vitamin D status and risk of pancreatic (32) and esophageal (33,34) cancer, caution should be taken in recommending high doses of vitamin D or sunlight exposure to the general public for prostate cancer prevention. Future analyses are warranted to confirm these results and to further clarify the effects of vitamin D on aggressive prostate cancer.

The Fat Soluble Vitamins are vitamins A, D, E and K. To some extent, this vitamin is different from water-soluble vitamins. This vitamin is found in fatty and oily part of food. This vitamin is only digested by the bile because it is not soluble in water. The following sections provide detailed descriptions of each vitamin type.

"Hi! This is Amy Proal. I wrote the article referenced at the start of the thread about vitamin D. Dr. Marshall is not concerned with vitamin D toxicity. Rather his molecular modeling research has clarified the actions of the two vitamin D metabolites 25-D and 1,25-D. The Vitamin D Receptor (VDR) is a fundamental receptor of the body - it controls the expression thousands of genes, as well as the activity of the innate immune system and the antimicrobial peptides. If you think of the VDR as a switch, 25-D (which is a corticosteroid) turns it off (inactivates it) and 1,25-D turn it on (activates it). What is commonly believed among vitamin D researchers is that if people supplement with extra vitamin D it will be converted into 1,25-D and activate the VDR. Unfortunately, Marshall's work revealed that the type of vitamin D derived from supplements and sun remains, for the most part, in it's precursor form 25-D. This means that the extra vitamin D we get from fortified food products and supplements is turning the VDR off, not on. That causes a decrease in immune function and gene transcription."

(VIDEO) Shedding light on the vitamin D deficiency 'crisis' By GrassRootsHealth.com Oct 11, 2009 - 4:49:39 PM San Diego, CA - Can vitamin D prevent 80% of the incidence of breast cancer? What is its affect on colon cancer and other major illnesses? These questions and more will be addressed when some of the most prominent vitamin D researchers in North America participate in the " Diagnosis & Treatment of Vitamin D Deficiency" seminar presented by GrassrootsHealth at the University of Toronto on Tuesday, November 3 from 8 a.m. - 5 p.m. GrassrootsHealth is the founder of D*action, an international public health project whose goal is to solve the vitamin D deficiency epidemic. GrassrootsHealth and D*action work with over 30 scientists, institutions and individuals committed to educate, test, and study vitamin D levels worldwide. At the conference, a group of physicians and researchers in the vitamin D field will discuss vitamin D's role in the potential prevention of many diseases, including breast cancer, colon cancer, type 1 diabetes and multiple sclerosis, the ultimate reduction in the incidence of infectious diseases and the economic impact of such action

Defining Adequate Vitamin D Intake : Cross-sectional and Intervention Studies Viljakainen, Heli Tuulikki University of Helsinki 2008-05-23 Doctoral dissertation (article-based) Vitamin D is required for normal bone growth and maintenance of the skeleton throughout life. In Finland, like in many other Western countries, the population suffers from inadequate or deficient vitamin D status, especially during winter, which is thought to increase the risk of osteoporosis. New strategies to prevent osteoporosis are actively being sought. The main objective of this thesis was to determine whether vitamin D is feasible in the primary prevention of osteoporosis; does it affect bone mineral accrual during the growth period? A second goal was to ascertain whether seasonal variation in calcitropic hormones affects bone remodelling, and to elucidate the vitamin D intake needed to overcome this variation in different age groups. In summary, vitamin D intake remains inadequate among the target groups of this thesis, as reflected by seasonal variation in calcitropic hormones and bone metabolism. Dietary intake of vitamin D should be increased to achieve at least an adequate vitamin D status (S-25-OHD>50 nmol/l) and possibly an optimal vitamin D status (S-25-OHD>80 nmol/l) throughout the year. This could be accomplished by introducing new vitamin D-fortified foods to the market."

"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."

"June 29, 2009 | Shelley Wood Boston, MA - A massive, National Institutes of Health-sponsored study looking at whether vitamin-D and/or omega-3 fatty-acid supplementation can reduce the risk of developing heart disease, stroke, or cancer will get under way in January 2010, according to a website for the study. Drs JoAnn Manson and Julie Buring (Harvard Medical School/ Brigham and Women's Hospital, Boston, MA) will head up the Vitamin D and Omega-3 Trial (VITAL). The study is aiming to enroll 20 000 men and women, one-quarter of whom will be black. According to a Brigham and Women's Hospital press release, the study is intentionally aiming to illuminate a potential racial and ethnic disparity hypothesized to be linked to vitamin D [1]. "African Americans have a higher risk of vitamin-D deficiency as well as a greater frequency of diabetes, hypertension, and certain types of cancer," a press release notes. For VITAL, women need to be over age 65 to enter the study; men need to be over age 60. Study participants will be randomized to one of four groups: daily vitamin D (2000 IU) and fish oil (1 g); daily vitamin D and fish-oil placebo; daily vitamin-D placebo and fish oil; or daily vitamin-D placebo and fish-oil placebo. The trial will run for five years and is expected to cost US $20 million."

Vitamin D and diabetes: improvement of glycemic control with vitamin D3 repletion. Schwalfenberg G. Can Fam Physician. 2008 Jun;54(6):864-6. PMID: 18556494 Conclusion These cases support information that is already known about VTD and its effect on the islet cell. As discussed above, this might be true only for vitamin D3 and not vitamin D2, although vitamin D2 has been shown to improve bone health. Vitamin D insufficiency or deficiency is common, and repletion might improve glycemic control early in type 2 diabetes. Diabetes is one of the fastest growing chronic diseases worldwide. Vitamin D3 is inexpensive and readily available. Well-designed clinical studies are required to ascertain if improving 25(OH)D levels from an insufficiency or deficiency to sufficiency improves glycemic control in diabetes. These studies need to be properly designed: a randomized controlled trial with VTD deficiency or insufficiency identified in diabetic patients of various ethnic

A critical review of Vitamin D and cancer: A report of the IARC Working Group on vitamin D William B. Grant Dermato-Endocrinology. Volume 1, Issue 1 January/February 2009 Pages: 25 - 33 The International Agency for Research on Cancer (IARC) released a report, Vitamin D and Cancer, on November 25, 2008. The report focused on the current state of knowledge and level of evidence of a causal association between vitamin D status and cancer risk. Although presenting and evaluating evidence for the beneficial role of UVB and vitamin D in reducing the risk of cancer, it discounted or omitted important evidence in support of the efficacy of vitamin D. The report largely dismissed or ignored ecological studies on the grounds that confounding factors might have affected the findings. The report accepted a preventive role of vitamin D in colorectal cancer but not for breast cancer.

"[Vitamin K and Bone Update. The biological effects of vitamin K(2) on bone quality.] Amizuka N, Li M, Guo Y, Liu Z, Suzuki R, Yamamoto T. Clin Calcium. 2009 Dec;19(12):1788-96. Japanese. PMID: 19949270 Post-transcriptional maturation with the presence of vitamin K(2) promotesgamma-carboxylation of osteocalcin, enabling further binding to hydroxyapatite, from which one could infer that vitamin K(2) increased the quality of bone matrix. For instance, vitamin K(2) rescued the impaired collagen mineralization caused by Mg insufficiency, by promoting a re-association of the process of collagen mineralization with mineralized nodules. Sodium warfarin, which antagonizes the function of vitamin K(2), reduced the binding of osteocalcin to bone matrices, and consequently resulted in crystalline particles being dispersed throughout the osteoid without forming mineralized nodules. Therefore,gamma-carboxylated Gla proteins mediated by vitamin K(2) appear to play a pivotal role in normal mineralization in bone."

Mango is a summer delicacy which is consumed worldwide. They are juicy, sweet and act as a natural coolant which is very effective in beating the summer heat. Many varieties of mango are available in the market which have different taste and flavors. They are usually consumed raw and are savored in fresh salads and juices. Mango shakes, pickles, sauces, ice-creams and smoothies are prepared from mangoes which provide different blend of flavor to them. Let us find out the nutritional and health benefits of mango. Nutritional Benefits of Mango Juice provides around 60 calories for 100 grams of its serving. It contains a lot of phytochemicals and nutrients and is a rich source of carbohydrates and fibre. Antioxidants and Vitamins like Vitamin-A, B, C, E and K are present in it. Mango is also a good source of various minerals like Calcium, Zinc, Potassium, Iron, Magnesium and Potassium. Some Main Benefits of Mango Juice - Beneficial for Prevents Cancer: Mangoes are rich in antioxidants which restrict the oxidation of cells in the body. These antioxidants are quercetin, isoquercitrin, astragalin, fisetin, gallic acid and methylgallat.

The litchi benefits have been tried and proven in countries such as China and India and have also been well documented in ancient Chinese books. They contain many nutrients and vitamins that help to fight against various diseases as well as being a treatment for skin care, child growth and strengthening the body.
Tetra Pak Juice of Litchi fruit contains 66 calories per 100 g, comparable to that in the table-grapes. It has no saturated fats or cholesterol, but composes of good amounts of dietary fiber, vitamins, and antioxidants.
Oligonol is a low molecular weight polyphenol found abundantly in litchi fruit. Oligonol has several anti-oxidant and anti-influenza virus actions. It also helps to improve blood circulation, reduces weight and protects the skin from harmful UVA rays.
Litchi, like citrus fruits, is an excellent source of vitamin C; 100 g fresh fruits provide 71.5 mg or 119% of daily-recommended value. Studies suggest that consumption of fruits rich in vitamin C helps the human body develop resistance against infectious agents and scavenge harmful, pro-inflammatory free radicals.
Litchi is a very good source of B-complex vitamins such as thiamin, niacin, and folates. These vitamins are essential since they function by acting as co-factors to help the body metabolize carbohydrates, protein, and fats.
Litchi also carries a very good amount of minerals like potassium and copper. Potassium is an important component of cell and body fluids help control heart rate and blood pressure; thus, it offers protection against stroke and coronary heart diseases. Copper is required in the production of red blood cells.some Health Benefits Of Litchi are

Sources of vitamin A. Vitamin A is a vitamin that much needed by our bodies. Vitamin A plays an important role for healthy vision and immunity.

Vitamin D is associated with improved survival in early-stage non-small cell lung cancer patients. Zhou W, Suk R, Liu G, Park S, Neuberg DS, Wain JC, Lynch TJ, Giovannucci E, Christiani DC. Cancer Epidemiol Biomarkers Prev. 2005 Oct;14(10):2303-9. PMID: 16214909 In conclusion, the joint effects of surgery season and recent vitamin D intake seem to be associated with the survival of early-stage non-small cell lung cancer patients. In summary, for early-stage NSCLC patients, patients who had surgery in summer with "high" recent vitamin D intake have a statistically significantly improved RFS and OS than patients who had surgery in winter with "low" vitamin D intake. These results should be confirmed in a prospective study to assess the serum vitamin D levels at time of surgery. If the results are confirmed, our results, combined with findings in other studies, suggest that dietary vitamin D supplementation may be advisable for early stages of lung cancer patients, particularly during the winter season and in groups that tend to be deficient in vitamin D.

Commonly recommended daily intake of vitamin D is not sufficient if sunlight exposure is limited. Glerup H, Mikkelsen K, Poulsen L, Hass E, Overbeck S, Thomsen J, Charles P, Eriksen EF. J Intern Med. 2000 Feb;247(2):260-8. PMID: 10692090 Conclusions. Severe vitamin D deficiency is prevalent amongst sunlight-deprived individuals living in Denmark. In veiled Arab women, vitamin D deficiency is the result of a combination of limitations in sunlight exposure and a low oral intake of vitamin D. The oral intake of vitamin D amongst veiled ethnic Danish Moslems was, however, very high, at 13.53 µg (approximately 600 IU), but they were still vitamin D-deficient. Our results suggest that the daily oral intake of vitamin D in sunlight-deprived individuals should exceed 600 IU; most probably it should be 1000 IU day-1 to secure a normal level of 25-hydroxyvitamin D. This finding is in contrast with the commonly used RDA (recommended daily allowance) for adults in Europe: 200 IU day-1.

The role of vitamin D in cancer prevention. Garland CF, Garland FC, Gorham ED, Lipkin M, Newmark H, Mohr SB, Holick MF. Am J Public Health. 2006 Feb;96(2):252-61. Epub 2005 Dec 27. Review. PMID: 16380576 DOI: 10.2105/AJPH.2004.045260 Vitamin D status differs by latitude and race, with residents of the northeastern United States and individuals with more skin pigmentation being at increased risk of deficiency. A PubMed database search yielded 63 observational studies of vitamin D status in relation to cancer risk, including 30 of colon, 13 of breast, 26 of prostate, and 7 of ovarian cancer, and several that assessed the association of vitamin D receptor genotype with cancer risk. The majority of studies found a protective relationship between sufficient vitamin D status and lower risk of cancer. The evidence suggests that efforts to improve vitamin D status, for example by vitamin D supplementation, could reduce cancer incidence and mortality at low cost, with few or no adverse effects.

Differences in vitamin D status between countries in young adults and the elderly. McKenna MJ. Am J Med. 1992 Jul;93(1):69-77. PMID: 1385673 PURPOSE: To compare vitamin D status between countries in young adults and in the elderly. MATERIALS AND METHODS: Reports on vitamin D status (as assessed by serum 25-hydroxyvitamin D) from 1971 to 1990 were reviewed. Studies were grouped according to geographic regions: North America (including Canada and the United States); Scandinavia (including Denmark, Finland, Norway, and Sweden); and Central and Western Europe (including Belgium, France, Germany, Ireland, The Netherlands, Switzerland, and the United Kingdom). RESULTS: Vitamin D status varies with the season in young adults and in the elderly, and is lower during the winter in Europe than in both North America and Scandinavia. Oral vitamin D intake is lower in Europe than in both North America and Scandinavia. Hypovitaminosis D and related abnormalities in bone chemistry are most common in elderly residents in Europe but are reported in all elderly populations. CONCLUSIONS: The vitamin D status in young adults and the elderly varies widely with the country of residence. Adequate exposure to summer sunlight is the essential means to ample supply, but oral intake augmented by both fortification and supplementation is necessary to maintain baseline stores. All countries should adopt a fortification policy. It seems likely that the elderly would benefit additionally from a daily supplement of 10 micrograms of vitamin D.
