    Meta-analysis of prospective cohort studies evaluating the association of saturated fat with cardiovascular disease.
    Siri-Tarino PW, Sun Q, Hu FB, Krauss RM.
    Am J Clin Nutr. 2010 Jan 13. [Epub ahead of print]
    PMID: 20071648
    doi:10.3945/ajcn.2009.27725

    Conclusions: A meta-analysis of prospective epidemiologic studies showed that there is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of CHD or CVD. More data are needed to elucidate whether CVD risks are likely to be influenced by the specific nutrients used to replace saturated fat.

    Fish consumption and risk of major chronic disease in men.
    Virtanen JK, Mozaffarian D, Chiuve SE, Rimm EB.
    Am J Clin Nutr. 2008 Dec;88(6):1618-25.
    PMID: 19064523
    doi:10.3945/ajcn.2007.25816

    Conclusions: Modest fish consumption was associated with a lower risk of total cardiovascular disease, consistent with cardiac mortality benefits but not with total cancer or overall major chronic disease; n-6 fatty acid consumption did not influence these relations.

    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

    Am J Clin Nutr. 2009 Sep;90(3):602-12. Epub 2009 Jun 2.
    PMID: 19491385
    doi:10.3945/ajcn.2008.27173

    Conclusions: We have not consistently identified intakes of meat, eggs, or dairy products as risk factors for breast cancer. Future studies should investigate the possible role of high-temperature cooking in the relation of red meat intake with breast cancer risk.

    Egg consumption, serum cholesterol, and cause-specific and all-cause mortality: the National Integrated Project for Prospective Observation of Non-communicable Disease and Its Trends in the Aged, 1980 (NIPPON DATA80).
    Nakamura Y, Okamura T, Tamaki S, Kadowaki T, Hayakawa T, Kita Y, Okayama A, Ueshima H; NIPPON DATA80 Research Group.
    Am J Clin Nutr. 2004 Jul;80(1):58-63.
    PMID: 15213028

    Results: The subjects were categorized into 5 egg consumption groups on the basis of their responses to a questionnaire (≥2/d, 1/d, 1/2 d, 1-2/wk, and seldom). There were 69, 1396, 1667, 1742, and 315 women in each of the 5 groups, respectively. Age-adjusted total cholesterol (5.21, 5.04, 4.95, 4.91, and 4.92 mmol/L in the 5 egg consumption categories, respectively) was related to egg consumption (P < 0.0001, analysis of covariance). In women, unadjusted IHD mortality and all-cause mortality differed significantly between the groups [IHD mortality: 1.1, 0.5, 0.4, 0.5, and 2.0 per 1000 person-years, respectively (P = 0.008, chi-square test); all-cause mortality: 14.8, 8.0, 7.5, 7.5, and 14.5 per 1000 person-years, respectively (P < 0.0001, chi-square test)]. In men, egg consumption was not related to age-adjusted total cholesterol. Cox analysis found that, in women, all-cause mortality in the 1-2-eggs/wk group was significantly lower than that in the 1-egg/d group, whereas no such relations were noted in men.

    Conclusion: Limiting egg consumption may have some health benefits, at least in women in geographic areas where egg consumption makes a relatively large contribution to total dietary cholesterol intake.

    Egg consumption in relation to cardiovascular disease and mortality: the Physicians' Health Study.
    Djoussé L, Gaziano JM.
    Am J Clin Nutr. 2008 Apr;87(4):964-9.
    PMID: 18400720

    Results: In an average follow-up of 20 y, 1550 new myocardial infarctions (MIs), 1342 incident strokes, and 5169 deaths occurred. Egg consumption was not associated with incident MI or stroke in a multivariate Cox regression. In contrast, adjusted hazard ratios (95% CI) for mortality were 1.0 (reference), 0.94 (0.87, 1.02), 1.03 (0.95, 1.11), 1.05 (0.93, 1.19), and 1.23 (1.11, 1.36) for the consumption of <1, 1>< 0.0001). This association was stronger among diabetic subjects, in whom the risk of death in a comparison of the highest with the lowest category of egg consumption was twofold (hazard ratio: 2.01; 95% CI: 1.26, 3.20; P for interaction = 0.09).

    Conclusions: Infrequent egg consumption does not seem to influence the risk of CVD in male physicians. In addition, egg consumption was positively related to mortality, more strongly so in diabetic subjects, in the study population.

    Plant-animal subsistence ratios and macronutrient energy estimations in worldwide hunter-gatherer diets.
    Cordain L, Miller JB, Eaton SB, Mann N, Holt SH, Speth JD.
    Am J Clin Nutr. 2000 Mar;71(3):682-92.
    PMID: 10702160

    Our analysis showed that whenever and wherever it was ecologically possible, hunter-gatherers consumed high amounts (45-65% of energy) of animal food. Most (73%) of the worldwide hunter-gatherer societies derived >50% (> or =56-65% of energy) of their subsistence from animal foods, whereas only 14% of these societies derived >50% (> or =56-65% of energy) of their subsistence from gathered plant foods. This high reliance on animal-based foods coupled with the relatively low carbohydrate content of wild plant foods produces universally characteristic macronutrient consumption ratios in which protein is elevated (19-35% of energy) at the expense of carbohydrates (22-40% of energy).

    Hypovitaminosis D is associated with insulin resistance and beta cell dysfunction.
    Chiu KC, Chu A, Go VL, Saad MF.
    Am J Clin Nutr. 2004 May;79(5):820-5.
    PMID: 15113720

    Conclusions: The data show a positive correlation of 25(OH)D concentration with insulin sensitivity and a negative effect of hypovitaminosis D on ß cell function. Subjects with hypovitaminosis D are at higher risk of insulin resistance and the metabolic syndrome. Further studies are required to explore the underlying mechanisms.

    Use of cod liver oil during the first year of life is associated with lower risk of childhood-onset type 1 diabetes: a large, population-based, case-control study.
    Stene LC, Joner G; Norwegian Childhood Diabetes Study Group.
    Am J Clin Nutr. 2003 Dec;78(6):1128-34.
    PMID: 14668274

    Conclusion: Cod liver oil may reduce the risk of type 1 diabetes, perhaps through the antiinflammatory effects of long-chain n-3 fatty acids.

    Relation of body fat indexes to vitamin D status and deficiency among obese adolescents.
    Lenders CM, Feldman HA, Von Scheven E, Merewood A, Sweeney C, Wilson DM, Lee PD, Abrams SH, Gitelman SE, Wertz MS, Klish WJ, Taylor GA, Chen TC, Holick MF; Elizabeth Glaser Pediatric Research Network Obesity Study Group.
    Am J Clin Nutr. 2009 Sep;90(3):459-67. Epub 2009 Jul 29.
    PMID: 19640956

    RESULTS: The mean (+/-SD) age of the adolescents was 14.9 +/- 1.4 y; 38 (66%) were female, and 8 (14%) were black. The mean (+/-SD) body mass index (in kg/m(2)) was 36 +/- 5, FM was 40.0 +/- 5.5%, and VAT was 12.4 +/- 4.3%. Seventeen of the adolescents were vitamin D deficient, but none had elevated PTH concentrations. Bone mineral content and bone mineral density were within 2 SDs of national standards. In a multivariate analysis, 25(OH)D decreased by 0.46 +/- 0.22 ng/mL per 1% increment in FM (beta +/- SE, P = 0.05), whereas PTH decreased by 0.78 +/- 0.29 pg/mL per 1% increment in VAT (P = 0.01). CONCLUSIONS: To the best of our knowledge, our results show for the first time that obese adolescents with 25(OH)D deficiency, but without elevated PTH concentrations, have a bone mass within the range of national standards (+/-2 SD). The findings provide initial evidence that the distribution of fat may be associated with vitamin D status, but this relation may be dependent on metabolic factors

    Association of low 25-hydroxyvitamin D concentrations with elevated parathyroid hormone concentrations and low cortical bone density in early pubertal and prepubertal Finnish girls.
    Cheng S, Tylavsky F, Kröger H, Kärkkäinen M, Lyytikäinen A, Koistinen A, Mahonen A, Alen M, Halleen J, Väänänen K, Lamberg-Allardt C.
    Am J Clin Nutr. 2003 Sep;78(3):485-92. Erratum in: Am J Clin Nutr. 2006 Jan;83(1):174.
    PMID: 12936933

    CONCLUSIONS: Vitamin D-deficient girls have low cortical BMD and high iPTH concentrations, which are consistent with secondary hyperparathyroidism. A low vitamin D concentration accompanied by high bone resorption (TRAP 5b) may limit the accretion of bone mass in young girls.

    Low serum 25-hydroxyvitamin D concentrations and secondary hyperparathyroidism in middle-aged white strict vegetarians.
    Lamberg-Allardt C, Kärkkäinen M, Seppänen R, Biström H.
    Am J Clin Nutr. 1993 Nov;58(5):684-9.
    PMID: 8237875

    In conclusion, white strict vegetarians are at risk of vitamin D deficiency, at least in the winter, primarily because of a low dietary vitamin D intake, despite a normal sunlight exposure in summer. Low serum 25(OH)D concentrations are accompanied by high S-iPTH concentrations, which also are affected by a low calcium intake. The effect of these changes on bone health remains to be evaluated.

    Fruit and vegetable consumption and bone mineral density: the Northern Ireland Young Hearts Project.
    McGartland CP, Robson PJ, Murray LJ, Cran GW, Savage MJ, Watkins DC, Rooney MM, Boreham CA.
    Am J Clin Nutr. 2004 Oct;80(4):1019-23.
    PMID: 15447914

    Conclusion: High intakes of fruit may be important for bone health in girls. It is possible that fruit's alkaline-forming properties mediate the body's acid-base balance. However, intervention studies are required to confirm the findings of this observational study.

    Optimal vitamin D status attenuates the age-associated increase in systolic blood pressure in white Americans: results from the third National Health and Nutrition Examination Survey.
    Judd SE, Nanes MS, Ziegler TR, Wilson PW, Tangpricha V.
    Am J Clin Nutr. 2008 Jan;87(1):136-41.
    PMID: 18175747

    Conclusions: SBP is inversely associated with serum vitamin D concentrations in nonhypertensive white persons in the United States. This observation provides a rationale for studies on the potential effects of vitamin D supplementation as a method to reduce SBP in persons at risk of hypertension.

    PMID: 19064523
    doi:10.3945/ajcn.2007.25816

    Conclusions: Modest fish consumption was associated with a lower risk of total cardiovascular disease, consistent with cardiac mortality benefits but not with total cancer or overall major chronic disease; n-6 fatty acid consumption did not influence these relations.
