    Hypovitaminosis D in British adults at age 45 y: nationwide cohort study of dietary and lifestyle predictors. Hyppönen E, Power C. Am J Clin Nutr. 2007 Mar;85(3):860-8. PMID: 17344510 Conclusion: Prevalence of hypovitaminosis D in the general population was alarmingly high during the winter and spring, which warrants action at a population level rather than at a risk group level. Data from the 1958 birth cohort suggest that, at different cutoffs for hypovitaminosis D, a substantial public health problem exists in British whites. Obese participants and those living in Scotland were at the highest risk of hypovitaminosis D. However, the prevalence in the general population was very high during the winter and spring, which suggests that, to improve the situation, action is required at a population level rather than at a risk-group level. In the United States, calls have gone out for an increase in vitamin D fortification of foods (11), and the data from the current study suggest that such action is also warranted in the United Kingdom. Vitamin D is currently available without prescription as a dietary supplement only as part of cod liver oil or multivitamin products; hence, a need clearly exists to consider increased availability of over-the-counter supplements. Hypovitaminosis D has been implicated in the development of serious conditions, including diabetes, various types of cancer, and cardiovascular diseases, in addition to its essential role in maintaining bone health (1, 2). The high rates of hypovitaminosis D reported in this study suggest that immediate action is needed to improve the vitamin D status of the British population.

Smoking trumps omega-3s to drive up atherosclerosis rates in Alaskan Eskimos - theheart... - 0 views

    "July 10, 2008 | Shelley Wood New York, NY - Despite eating a diet rich in omega-3 fatty acids, Alaskan Eskimo are developing subclinical atherosclerosis at an early age, likely due in large part to heavy smoking, a new study shows [1]. According to investigators, in a paper published online July 10, 2008 in Stroke, rates of carotid atherosclerosis in the mostly young to middle-aged subjects participating in the Genetics of Coronary Artery Disease in Alaska Natives (GOCADAN) study were significantly higher than those reported in US population-based studies of other ethnic groups. But as Dr Alexis Cutchins (Weill Cornell Medical College, New York, NY) and colleagues report, rates of current smoking among the Eskimo population studied were also four to six times higher than that of other US populations in similar studies. "I don't think there's anything very surprising here, but I guess what is novel is that the findings relate to a population that has not been studied much, if at all, in this regard," study coauthor Dr Mary J Roman (Weill Cornell Medical College) told heartwire. "And I think that the message is one that has public-health implications for everybody else: this is basically a reiteration of the fact that smoking is a very potent cardiovascular risk factor, and I think the indoctrination that most of us have received about the ills of smoking have clearly not penetrated the Alaska Eskimo population.""

    Intima-media thickness of the carotid artery and the distribution of lipoprotein subclasses in men aged 40 to 49 years between whites in the United States and the Japanese in Japan for the ERA JUMP study. Sekikawa A, Ueshima H, Sutton-Tyrrell K, Kadowaki T, El-Saed A, Okamura T, Takamiya T, Ueno Y, Evans RW, Nakamura Y, Edmundowicz D, Kashiwagi A, Maegawa H, Kuller LH. Metabolism. 2008 Feb;57(2):177-82. PMID: 18191046 doi: 10.1016/j.metabol.2007.08.022. In men in the post World War II birth cohort, i.e., men aged 40-49, whites in the United States (U.S.) had significantly higher levels of intima-media thickness of the carotid arteries (IMT) than the Japanese in Japan. The whites had significantly higher levels of large very-low-density-lipoprotein particles and significantly lower levels of large high-density-lipoprotein particles than the Japanese, whereas the two populations had similar levels of small low-density-lipoprotein particles. The two populations had similar associations of IMT with NMR lipoproteins. Adjusting for NMR lipoproteins did not attenuate the significant difference in IMT between the two populations (0.671 ± 0.006 for the whites and 0.618 ± 0.006 mm for the Japanese, P=0.01, mean (standard error)). Differences in the distributions of NMR lipoproteins between the two populations did not explain the higher IMT in the whites.

    Serum 25-hydroxyvitamin D status of the US population: 1988-1994 compared with 2000-2004. Looker AC, Pfeiffer CM, Lacher DA, Schleicher RL, Picciano MF, Yetley EA. Am J Clin Nutr. 2008 Dec;88(6):1519-27. PMID: 19064511 doi:10.3945/ajcn.2008.26182 Conclusions: Overall, mean serum 25(OH)D was lower in 2000-2004 than 1988-1994. Assay changes unrelated to changes in vitamin D status accounted for much of the difference in most population groups. In an adult subgroup, combined changes in BMI, milk intake, and sun protection appeared to contribute to a real decline in vitamin D status. In summary, age-standardized mean serum 25(OH)D concentrations based on observed values were significantly lower in 2000-2004 than in 1988-1994 in all groups examined. Adjustment for assay changes noticeably reduced the difference between surveys. However, mean serum 25(OH)D concentrations remained significantly lower in males (except Mexican Americans) in NHANES 2000-2004 than in NHANES III, even after adjustment for assay differences. This remaining difference likely represents a real decline in vitamin D status. Changes in BMI, milk intake, and sun protection appeared to contribute to this decline in a subgroup of non-Hispanic white adults. The possibility that trends in overweight, sun protection, and milk intake may continue supports the need to continue monitoring the serum 25(OH)D status of the population

Mean Serum 25(OH)D Levels Decreasing in All Categories of the US Population - 0 views

  •  
    March 27, 2009 - A significant decrease in serum 25-hydroxyvitamin D (25[OH]D) levels has led to an increase in vitamin D insufficiency in the US population, especially in racial and ethnic groups, according to results of a population-based study reported in the March 23 issue of the Archives of Internal Medicine. "Vitamin D insufficiency has been associated with increases in cardiovascular disease, cancer, and infection," write Adit A. Ginde, MD, from the Department of Emergency Medicine at the University of Colorado Denver School of Medicine, Aurora, Colorado, and colleagues. "Vitamin D supplementation appears to mitigate the incidence and adverse outcomes of these diseases and may reduce all-cause mortality." [...] "These findings have important implications for health disparities and public health," the study authors conclude. "Our data provide additional evidence that current recommendations for vitamin D supplementation (200-600 IU/d) are inadequate to achieve optimal serum 25(OH)D levels in most of the US population." They add that large, randomized controlled trials of higher doses of vitamin D supplementation are needed to evaluate their effect on general health and mortality.

    Cholesterol, coconuts, and diet on Polynesian atolls: a natural experiment: the Pukapuka and Tokelau island studies. Prior IA, Davidson F, Salmond CE, Czochanska Z. Am J Clin Nutr. 1981 Aug;34(8):1552-61. PMID: 7270479 Two populations of Polynesians living on atolls near the equator provide an opportunity to investigate the relative effects of saturated fat and dietary cholesterol in determining serum cholesterol levels. The habitual diets of the toll dwellers from both Pukapuka and Tokelau are high in saturated fat but low in dietary cholesterol and sucrose. Coconut is the chief source of energy for both groups. Tokelauans obtain a much higher percentage of energy from coconut than the Pukapukans, 63% compared with 34%, so their intake of saturated fat is higher. The serum cholesterol levels are 35 to 40 mg higher in Tokelauans than in Pukapukans. These major differences in serum cholesterol levels are considered to be due to the higher saturated fat intake of the Tokelauans. Analysis of a variety of food samples, and human fat biopsies show a high lauric (12:0) and myristic (14:0) content. Vascular disease is uncommon in both populations and there is no evidence of the high saturated fat intake having a harmful effect in these populations.

    A comparison of egg consumption with other modifiable coronary heart disease lifestyle risk factors: a relative risk apportionment study. Barraj L, Tran N, Mink P. Risk Anal. 2009 Mar;29(3):401-15. Epub 2008 Nov 4. PMID: 19000074 DOI: 10.1111/j.1539-6924.2008.01149.x Guidelines from the American Heart Association (AHA) recommend that healthy adults limit their intake of dietary cholesterol to less than 300 mg per day. Since a large egg contains about 71% of that amount, the AHA recommends restricting egg consumption unless dietary cholesterol intakes from other sources are limited. We applied a risk apportionment approach to estimate the contribution of egg consumption and other modifiable lifestyle risk factors (e.g., smoking, poor diet, minimal exercise, and alcohol intake) to coronary heart disease (CHD) risk at the population level. Specifically, we categorized the U.S. adult population ages 25+ into distinct risk groups based on the prevalence of modifiable lifestyle risk factors and applied an apportionment model, typically used to assess risk contribution at the individual level, to estimate the contribution of egg intake to CHD risk. Our analysis shows that the combination of modifiable lifestyle risk factors accounts for less than 40% of the population CHD mortality. For the majority of U.S. adults age 25+, consuming one egg a day accounts for <1% of CHD risk. Hence, focusing on decreasing egg intake as an approach to modify CHD risk would be expected to yield minimal results relative to changing other behaviors such as smoking and other dietary habits.

    Circulating vitamin D3 and 25-hydroxyvitamin D in humans: An important tool to define adequate nutritional vitamin D status. Hollis BW, Wagner CL, Drezner MK, Binkley NC. J Steroid Biochem Mol Biol. 2007 Mar;103(3-5):631-4. Epub 2007 Jan 10. PMID: 17218096 In the present study, we sought to investigate what circulating 25(OH)D levels would result in populations exhibiting no substrate limitations to the vitamin D-25-hydroxylase. To perform this, we chose two distinct populations. The first were individuals from a year-found sunny environment who spent a good deal of time outdoors. The second were a group of lactating women receiving a substantial daily oral dose of vitamin D3. Surprisingly, a study such as this previously had not been undertaken. There are several reasons for this. First, finding a group of sun-exposed individuals is not an easy task; in fact, we had to go to Hawaii to find them. Secondly, very few studies have been performed where subjects actually received adequate vitamin D3 supplementation to make them replete. Finally, it is very difficult and costly to measure circulating vitamin D3 and relate it to circulating 25(OH)D. The results of our study are far-reaching. This study also demonstrates that individuals can be vitamin D deficient with significant sun exposure if the skin area exposed is limited as was suggested several years ago (19). Finally, whether one receives their vitamin D3 orally or through UV exposure, the vitamin D-25-hydroxylase appears to handle it in an equivalent fashion with respect to maintaining circulating 25(OH)D levels. Thus, we believe that the relationship between circulating vitamin D and 25(OH)D may define adequate nutritional vitamin D status.

EFSA sets lower tolerable intake level for cadmium in food - 0 views

  •  
    The European Food Safety Authority's Panel on contaminants in the food chain has set a reduced tolerable weekly intake (TWI)[1] for cadmium of 2.5 micrograms per kilogram of body weight (µg/kg bw), based on an analysis of new data. The TWI is the level at which adverse effects are not expected. Average dietary exposure to cadmium for adults across Europe is around this level. Some population groups - vegetarians, children, smokers and people living in highly contaminated areas - can have a higher level of exposure up to twice the TWI. However, the Panel concluded that even for these groups the risk of adverse effects would be very low. The Panel concluded that current exposure to cadmium at the level of the population should be reduced.

  •  
    A recently published study in Nutrition and Cancer (60(5), 643-651) by researchers at Kansai Medical University in Osaka, Japan has shown that AHCC (Active Hexose Correlated Compound) enhances immune function by increasing the number of dendritic cells (DCs). DCs are a key part of the immune system responsible for presenting foreign substances to other immune system cells. The study was conducted in a double-blind randomized fashion where twenty-one healthy subjects received a placebo or AHCC at 3.0 g/day for 4 weeks. Blood samples were obtained and measured at baseline and at 4 weeks. The number of circulating types of DCs was measured which included CD 11c+ DCs (myeloid DC population; DC1) and CD11c- DCs (lymphoid DC population; DC2). Other parameters measured included mixed-leukocyte reaction (MLR), natural killer (NK) cell activity, the proliferative response of T lymphocytes toward mitogen (phytohemagglutinin [PHA]) and cytokine production of interleukin (IL)-2, IL-4, IL-6, IL-10, interferon gamma-gamma, and (alpha)-tumor necrosis factor.

Coconut oil - Wikipedia, the free encyclopedia - 0 views

  •  
    "Coconut oil is extracted from the kernel or meat of matured coconut harvested from the coconut palm (Cocos nucifera). Throughout the tropical world it has provided the primary source of fat in the diets of millions of people for generations. It has various applications in food, medicine, and industry. What makes coconut oil different from most other dietary oils is the basic building blocks or fatty acids making up the oil. Coconut oil is composed predominately of a special group of fat molecules known as medium chain fatty acids (MCFA). The majority of fats in the human diet are composed almost entirely of long chain fatty acids (LCFA). The primary difference between MCFA and LCFA is the size of the molecule, or more precisely, the length of the carbon chain that makes up the backbone of the fatty acid. MCFA have a chain length of 6 to 12 carbons. LCFA contain 14 or more carbon Historically, many populations within the tropics have used coconut medicinally as a treatment for a wide variety of ailments.[8] A study into the effects of a "diet rich in.." medium-chain fatty acids (such as in coconut oil and butter) concluded that "MCFAs in the form of MCTs significantly increased plasma triacylglycerol and LDL-cholesterol concentrations and the ratio of LDL to HDL cholesterol and thereby resulted in a less beneficial lipid profile overall."[9] Further, research done by nutritionist Mary Enig has found that non-hydrogenated coconut oil (i.e. extra-virgin) consumed in moderate amounts "is at worst neutral with respect to atherogenicity of fats and oils and, in fact, is likely to be a beneficial oil for prevention and treatment of some heart disease."[10] The lack of negative effects of a diet rich in coconut oil on cardiovascular health is born out in studies of Polynesian populations who consume as much as 65% of their calories in the form of coconut oil and yet, have almost no incidence of heart disease and normal blood lipid profiles.[11]

    Serum 25(OH)-vitamin D concentration and risk of esophageal squamous dysplasia. Abnet CC, Chen W, Dawsey SM, Wei WQ, Roth MJ, Liu B, Lu N, Taylor PR, Qiao YL. Cancer Epidemiol Biomarkers Prev. 2007 Sep;16(9):1889-93. PMID: 17855710 doi: 10.1158/1055-9965.EPI-07-0461 Background: Squamous dysplasia is the precursor lesion for esophageal squamous cell carcinoma, and nutritional factors play an important role in the etiology of this cancer. Previous studies using a variety of measures for vitamin D exposure have reached different conclusions about the association between vitamin D and the risk of developing esophageal cancer. Conclusions: Higher serum 25(OH)D concentrations were associated with significantly increased risk of squamous dysplasia. No obvious source of measured or unmeasured confounding explains this finding. In conclusion, we found that a higher serum 25(OH)D concentration was associated with an increased risk of esophageal squamous dysplasia, the precursor lesion for ESCC. This finding concurs with our previous prospective study which found that higher vitamin D status was associated with increased risk of incident ESCC in this same population. These unexpected findings suggest that further studies of the association of vitamin D and digestive tract cancers are needed before the effect of vitamin D in different populations can be elucidated.

Optimal Serum 25-Hydroxyvitamin D Levels for Multiple Health Outcomes - SpringerLink - ... - 0 views

    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.
