    High-dose vitamin D3 supplementation in a cohort of breastfeeding mothers and their infants: a 6-month follow-up pilot study. Wagner CL, Hulsey TC, Fanning D, Ebeling M, Hollis BW. Breastfeed Med. 2006 Summer;1(2):59-70. PMID: 17661565 doi:10.1089/bfm.2006.1.59. Objective: To examine the effect of high-dose maternal vitamin D3 (vitD) supplementation on the nutritional vitD status of breastfeeding (BF) women and their infants compared with maternal and infant controls receiving 400 and 300 IU vitD/day, respectively. Design: Fully lactating women (n = 19) were enrolled at 1-month postpartum into a randomized- control pilot trial. Each mother received one of two treatments for a 6-month study period: 0 or 6000 IU vitD3 plus a prenatal vitamin containing 400 IU vitD3. The infants of mothers assigned to the control group received 300 IU vitD3/day; those infants of mothers in the high-dose group received 0 IU (placebo). Maternal serum and milk vitD and 25(OH)D were measured at baseline then monthly; infant serum vitD and 25(OH)D were measured at baseline, and months 4 and 7. Urinary calcium/creatinine ratios were measured monthly in both mothers and infants. Dietary and BF history and outdoor activity questionnaires were completed at each visit. Changes in skin pigmentation were measured by spectrophotometry. Data were analyzed using chi-square, t-test, and analysis of variance (ANOVA) on an intent-to-treat basis. Conclusion: With limited sun exposure, an intake of 400 IU/day vitamin D3 did not sustain circulating maternal 25(OH)D levels, and thus, supplied only extremely limited amounts of vitamin D to the nursing infant via breast milk. Infant levels achieved exclusively through maternal supplementation were equivalent to levels in infants who received oral vitamin D supplementation. Thus, a maternal intake of 6400 IU/day vitamin D elevated circulating 25(OH)D in both mother and nursing infant.

    Marine-derived n-3 fatty acids and atherosclerosis in Japanese, Japanese-American, and white men: a cross-sectional study. Sekikawa A, Curb JD, Ueshima H, El-Saed A, Kadowaki T, Abbott RD, Evans RW, Rodriguez BL, Okamura T, Sutton-Tyrrell K, Nakamura Y, Masaki K, Edmundowicz D, Kashiwagi A, Willcox BJ, Takamiya T, Mitsunami K, Seto TB, Murata K, White RL, Kuller LH; ERA JUMP (Electron-Beam Tomography, Risk Factor Assessment Among Japanese and U.S. Men in the Post-World War II Birth Cohort) Study Group. J Am Coll Cardiol. 2008 Aug 5;52(6):417-24. PMID: 18672160 Conclusions Very high levels of marine-derived n-3 FAs have anti-atherogenic properties independent of traditional cardiovascular risk factors and may contribute to lower burden of atherosclerosis in Japanese in Japan, which is unlikely due to genetic factors.

    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.

    Vitamin D-Related Changes in Physical Performance: A Systematic Review. Annweiler C, Schott AM, Berrut G, Fantino B, Beauchet O. J Nutr Health Aging. 2009;13(10):893-898. PMID: 19924350 Conclusions: The findings show that the association between vitamin D and physical performance remains controversial. Observational studies and clinical trials yielded divergent results, which highlights the complex and to date still poorly understood association between serum vitamin D concentration or vitamin D supplementation and physical performance.

    Serum 25-Hydroxyvitamin D Levels Among US Children Aged 1 to 11 Years: Do Children Need More Vitamin D? Mansbach JM, Ginde AA, Camargo CA Jr. Pediatrics. 2009 Nov;124(5):1404-1410. PMID: 19951983 CONCLUSIONS: On the basis of a nationally representative sample of US children aged 1 to 11 years, millions of children may have suboptimal levels of 25(OH)D, especially non-Hispanic black and Hispanic children. More data in children are needed not only to understand better the health implications of specific serum levels of 25(OH)D but also to determine the appropriate vitamin D supplement requirements for children.

    "[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."

    Biochemical effects of consumption of eggs containing omega-3 polyunsaturated fatty acids. Ohman M, Akerfeldt T, Nilsson I, Rosen C, Hansson LO, Carlsson M, Larsson A. Ups J Med Sci. 2008;113(3):315-23.P MID: 18991244 Today, eggs with an increased content of -3 fatty acids are available but there are few publications on the effects of consumption of such eggs on the lipoproteins and acute phase markers in humans. The aim of the present study was to evaluate the effects of consumption of standard eggs and -3 enriched eggs on lipoproteins, glucose and inflammation markers. Nineteen healthy volunteers consumed one extra egg per day of either standard eggs or omega-3 enriched eggs in a double-blind, cross-over study. The duration of each period was 1 month. The effects of the different egg diets on apolipoprotein A1 and B (Apo A1 and B), lipoprotein (a), creatinine, cystatin C, C-reactive protein, serum amyloid protein A, interleukin 6, triglycerides, glucose, total-, high-density lipoprotein and low-density lipo-protein cholesterol concentrations were analyzed. Addition of one regular egg per day to the normal diet had no negative impact on blood lipids or inflammation markers. Consumption of omega-3 enriched eggs resulted in higher levels of ApoA1, lower ApoB/ApoA1 ratio and lower plasma glucose. These effects have been associated in previous studies with a reduced risk for cardiovascular mortality and diabetes.

    Egg breakfast enhances weight loss. Vander Wal JS, Gupta A, Khosla P, Dhurandhar NV. Int J Obes (Lond). 2008 Oct;32(10):1545-51. Epub 2008 Aug 5. PMID: 18679412 doi: 10.1038/ijo.2008.130 Conclusions The egg breakfast enhances weight loss, when combined with an energy-deficit diet, but does not induce weight loss in a free-living condition. The inclusion of eggs in a weight management program may offer a nutritious supplement to enhance weight loss.

    Dietary cholesterol and the risk of cardiovascular disease in patients: a review of the Harvard Egg Study and other data. Jones PJ. Int J Clin Pract Suppl. 2009 Oct;(163):1-8, 28-36. English, French. PMID: 19751443 For many years, both the medical community and the general public have incorrectly associated eggs with high serum cholesterol and being deleterious to health, even though cholesterol is an essential component of cells and organisms. It is now acknowledged that the original studies purporting to show a linear relation between cholesterol intake and coronary heart disease (CHD) may have contained fundamental study design flaws, including conflated cholesterol and saturated fat consumption rates and inaccurately assessed actual dietary intake of fats by study subjects. Newer and more accurate trials, such as that conducted by Frank B. Hu of the Harvard School of Public Health (1999), have shown that consumption of up to seven eggs per week is harmonious with a healthful diet, except in male patients with diabetes for whom an association in higher egg intake and CHD was shown. The degree to which serum cholesterol is increased by dietary cholesterol depends upon whether the individual's cholesterol synthesis is stimulated or down-regulated by such increased intake, and the extent to which each of these phenomena occurs varies from person to person. Several recent studies have shed additional light on the specific interplay between dietary cholesterol and cardiovascular health risk. It is evident that the dynamics of cholesterol homeostasis, and of development of CHD, are extremely complex and multifactorial. In summary, the earlier purported adverse relationship between dietary cholesterol and heart disease risk was likely largely over-exaggerated.
