    Intake of fish and n3 fatty acids and risk of coronary heart disease among Japanese: the Japan Public Health Center-Based (JPHC) Study Cohort I.
    Iso H, Kobayashi M, Ishihara J, Sasaki S, Okada K, Kita Y, Kokubo Y, Tsugane S; JPHC Study Group.
    Circulation. 2006 Jan 17;113(2):195-202. Epub 2006 Jan 9.
    PMID: 16401768
    doi: 10.1161/CIRCULATIONAHA.105.581355

    Conclusions- Compared with a modest fish intake of once a week or &20 g/d, a higher intake was associated with substantially reduced risk of coronary heart disease, primarily nonfatal cardiac events, among middle-aged persons

    High dietary methionine intake increases the risk of acute coronary events in middle-aged men.
    Virtanen JK, Voutilainen S, Rissanen TH, Happonen P, Mursu J, Laukkanen JA, Poulsen H, Lakka TA, Salonen JT.
    Nutr Metab Cardiovasc Dis. 2006 Mar;16(2):113-20. Epub 2005 Nov 2.
    PMID: 16487911
    doi:10.1016/j.numecd.2005.05.005

    Conclusions
    The main finding of this study is that long-term, moderately high dietary methionine intake may increase the risk of acute coronary events in middle-aged Finnish men free of prior CHD. More prospective research is needed to confirm the role of dietary methionine in the development of CVD, and whether its effects are independent of homocysteine.

  •  
    Maternal vitamin D status during pregnancy and childhood bone mass at age 9 years: a longitudinal study.
    Javaid MK, Crozier SR, Harvey NC, Gale CR, Dennison EM, Boucher BJ, Arden NK, Godfrey KM, Cooper C; Princess Anne Hospital Study Group.
    Lancet. 2006 Jan 7;367(9504):36-43. Erratum in: Lancet. 2006 May 6;367(9521):1486.
    PMID: 16399151
    doi:10.1016/S0140-6736(06)67922-1

    Interpretation
    Maternal vitamin D insufficiency is common during pregnancy and is associated with reduced bone-mineral accrual in the offspring during childhood; this association is mediated partly through the concentration of umbilical venous calcium. Vitamin D supplementation of pregnant women, especially during winter months, could lead to longlasting reductions in the risk of osteoporotic fracture in their offspring.

NEJM -- Low-Carbohydrate-Diet Score and the Risk of Coronary Heart Disease in Women - 0 views

    Low-carbohydrate-diet score and the risk of coronary heart disease in women.
    Halton TL, Willett WC, Liu S, Manson JE, Albert CM, Rexrode K, Hu FB.
    N Engl J Med. 2006 Nov 9;355(19):1991-2002.
    PMID: 17093250

    Conclusions Our findings suggest that diets lower in carbohydrate and higher in protein and fat are not associated with increased risk of coronary heart disease in women. When vegetable sources of fat and protein are chosen, these diets may moderately reduce the risk of coronary heart disease.

    Association of low intake of milk and vitamin D during pregnancy with decreased birth weight.
    Mannion CA, Gray-Donald K, Koski KG.

    PMID: 16636326

    Interpretation: Milk and vitamin D intakes during pregnancy are each associated with infant birth weight, independently of other risk factors.

Prospective Study of Predictors of Vitamin D Status and Cancer Incidence and Mortality ... - 0 views

  •  
    Prospective study of predictors of vitamin D status and cancer incidence and mortality in men.
    Giovannucci E, Liu Y, Rimm EB, Hollis BW, Fuchs CS, Stampfer MJ, Willett WC.
    J Natl Cancer Inst. 2006 Apr 5;98(7):451-9.
    PMID: 16595781
    doi:10.1093/jnci/djj101

    Conclusions: Low levels of vitamin D may be associated with increased cancer incidence and mortality in men, particularly for digestive-system cancers. The vitamin D supplementation necessary to achieve a 25(OH)D increment of 25 nmol/L may be at least 1500 IU/day.

    Association between serum 25(OH)D concentrations and bone stress fractures in Finnish young men.
    Ruohola JP, Laaksi I, Ylikomi T, Haataja R, Mattila VM, Sahi T, Tuohimaa P, Pihlajamäki H.
    J Bone Miner Res. 2006 Sep;21(9):1483-8.
    doi: 10.1359/jbmr.060607

    Conclusions: A lower level of serum 25(OH)D concentration may be a generally predisposing element for bone stress fractures. Considering the obvious need of additional vitamin D in prevention of stress fractures, the effects of vitamin D fortification of foods and supplementation will be subjects of interest for future research

  •  
    A prospective nested case-control study of vitamin D status and pancreatic cancer risk in male smokers.
    Stolzenberg-Solomon RZ, Vieth R, Azad A, Pietinen P, Taylor PR, Virtamo J, Albanes D.
    Cancer Res. 2006 Oct 15;66(20):10213-9.
    PMID: 17047087
    doi: 10.1158/0008-5472.CAN-06-1876

    Contrary to expectations, subjects with higher prediagnostic vitamin D status had an increased pancreatic cancer risk compared with those with lower status. Our findings need to be replicated in other populations and caution is warranted in their interpretation and implication. Our results are intriguing and may provide clues that further the understanding of the etiology of this highly fatal cancer.

  •  
    A seasonal variation of calcitropic hormones, bone turnover and bone mineral density in early and mid-puberty girls - a cross-sectional study.
    Viljakainen HT, Palssa A, Kärkkäinen M, Jakobsen J, Cashman KD, Mølgaard C, Lamberg-Allardt C.
    Br J Nutr. 2006 Jul;96(1):124-30.
    PMID: 16870000

    Seasonal variation in S-25-OHD and bone remodelling markers accompanied by negative correlation between S-25-OHD and S-iPTH was seen in this cross-sectional study of adolescent girls. In addition, the seasonal rhythm contributed 7.0-7.6 % difference in the BMD of lumbar vertebrae and left femur in early puberty girls. This variation should be avoided since it could hamper peak bone mass attainment.

Vitamin D Status and Glucose Homeostasis in the 1958 British Birth Cohort - Diabetes Care - 0 views

  •  
    Vitamin D status and glucose homeostasis in the 1958 British birth cohort: the role of obesity.
    Hyppönen E, Power C.
    Diabetes Care. 2006 Oct;29(10):2244-6.
    PMID: 17003300
    doi: 10.2337/dc06-0946

    CONCLUSIONS-Body size was a strong determinant for 25(OH)D, with concentrations being suboptimal in most obese participants. Randomized controlled trials [using dosages sufficient to improve 25(OH)D also for the obese] are required to determine whether clinically relevant improvements in glucose metabolism can be obtained by vitamin D supplementation.

    Serum 25-hydroxyvitamin D3 concentrations and carotid artery intima-media thickness among type 2 diabetic patients.
    Targher G, Bertolini L, Padovani R, Zenari L, Scala L, Cigolini M, Arcaro G.
    Clin Endocrinol (Oxf). 2006 Nov;65(5):593-7.
    PMID: 17054459
    DOI: 10.1111/j.1365-2265.2006.02633.x

    CONCLUSIONS: Hypovitaminosis D is highly prevalent in type 2 diabetic adults and is strongly and independently associated with increased carotid IMT. Further investigation into whether vitamin D may play a role in the prevention of atherosclerosis appears to be warranted.

    In conclusion, our results show that type 2 diabetic adults have significant reductions in serum 25(OH)D concentrations (vs matched controls) that predict preclinical atherosclerosis, independent of classical risk factors, renal function tests, inflammatory markers, use of medications and presence of the metabolic syndrome. These findings suggest the need for ongoing evaluation of the possible protective role of vitamin D3 supplementation in the development of atherosclerosis.
