Fatty fish and fish omega-3 fatty acid intakes decrease the breast cancer risk: a case-control study. Kim J, Lim SY, Shin A, Sung MK, Ro J, Kang HS, Lee KS, Kim SW, Lee ES. BMC Cancer. 2009 Jun 30;9:216. PMID: 19566923 doi: 10.1186/1471-2407-9-216 Conclusion These results suggest that high consumption of fatty fish is associated with a reduced risk for breast cancer, and that the intake of omega-3 fatty acids from fish is inversely associated with postmenopausal breast cancer risk

Nutritional contribution of eggs to American diets. Song WO, Kerver JM. J Am Coll Nutr. 2000 Oct;19(5 Suppl):556S-562S. PMID: 11023007 Conclusions: In this cross-sectional and population-based study, egg consumption made important nutritional contributions to the American diet and was not associated with high serum cholesterol concentrations.

Meat, eggs, dairy products, and risk of breast cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. Pala V, Krogh V, Berrino F, Sieri S, Grioni S, Tjønneland A, Olsen A, Jakobsen MU, Overvad K, Clavel-Chapelon F, Boutron-Ruault MC, Romieu I, Linseisen J, Rohrmann S, Boeing H, Steffen A, Trichopoulou A, Benetou V, Naska A, Vineis P, Tumino R, Panico S, Masala G, Agnoli C, Engeset D, Skeie G, Lund E, Ardanaz E, Navarro C, Sánchez MJ, Amiano P, Svatetz CA, Rodriguez L, Wirfält E, Manjer J, Lenner P, Hallmans G, Peeters PH, van Gils CH, Bueno-de-Mesquita HB, van Duijnhoven FJ, Key TJ, Spencer E, Bingham S, Khaw KT, Ferrari P, Byrnes G, Rinaldi S, Norat T, Michaud DS, Riboli E. 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 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 < 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.

Egg consumption in relation to cardiovascular disease and mortality: the story gets more complex. Eckel RH. Am J Clin Nutr. 2008 Apr;87(4):799-800. PMID: 1840069

Egg consumption and risk of type 2 diabetes in men and women. Djoussé L, Gaziano JM, Buring JE, Lee IM. Diabetes Care. 2009 Feb;32(2):295-300. Epub 2008 Nov 18. PMID: 1901777 doi: 10.2337/dc08-1271 RESULTS-During mean follow-up of 20.0 years in men and 11.7 years in women, 1,921 men and 2,112 women developed type 2 diabetes. Compared with no egg consumption, multivariable adjusted hazard ratios for type 2 diabetes were 1.09 (95% CI 0.87-1.37), 1.09 (0.88-1.34), 1.18 (0.95-1.45), 1.46 (1.14-1.86), and 1.58 (1.25-2.01) for consumption of <0.0001). CONCLUSIONS-These data suggest that high levels of egg consumption (daily) are associated with an increased risk of type 2 diabetes in men and women. Confirmation of these findings in other populations is warranted.

A prospective study of egg consumption and risk of cardiovascular disease in men and women. Hu FB, Stampfer MJ, Rimm EB, Manson JE, Ascherio A, Colditz GA, Rosner BA, Spiegelman D, Speizer FE, Sacks FM, Hennekens CH, Willett WC. JAMA. 1999 Apr 21;281(15):1387-94. PMID: 10217054 Results We documented 866 incident cases of CHD and 258 incident cases of stroke in men during 8 years of follow-up and 939 incident cases of CHD and 563 incident cases of stroke in women during 14 years of follow-up. After adjustment for age, smoking, and other potential CHD risk factors, we found no evidence of an overall significant association between egg consumption and risk of CHD or stroke in either men or women. The relative risks (RRs) of CHD across categories of intake were less than 1 per week (1.0), 1 per week (1.06), 2 to 4 per week (1.12), 5 to 6 per week (0.90), and >=1 per day (1.08) (P for trend=.75) for men; and less than 1 per week (1.0), 1 per week (0.82), 2 to 4 per week (0.99), 5 to 6 per week (0.95), and >=1 per day (0.82) (P for trend=.95) for women. In subgroup analyses, higher egg consumption appeared to be associated with increased risk of CHD only among diabetic subjects (RR of CHD comparing more than 1 egg per day with less than 1 egg per week among diabetic men, 2.02 [95% confidence interval, 1.05-3.87; P for trend=.04], and among diabetic women, 1.49 [0.88-2.52; P for trend=.008]). Conclusions These findings suggest that consumption of up to 1 egg per day is unlikely to have substantial overall impact on the risk of CHD or stroke among healthy men and women. The apparent increased risk of CHD associated with higher egg consumption among diabetic participants warrants further research.

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.

Meat and egg consumption and risk of breast cancer among Chinese women. Zhang CX, Ho SC, Chen YM, Lin FY, Fu JH, Cheng SZ. Cancer Causes Control. 2009 Jun 17. [Epub ahead of print] PMID: 19533390 Conclusions This study suggested that processed meat intake was associated with a possible increased risk of breast cancer. There was no significant association between consumption of total and red meat, poultry, fish, or egg with breast cancer risk

Association between type of dietary fish and seafood intake and the risk of incident type 2 diabetes: the European prospective investigation of cancer (EPIC)-Norfolk cohort study. Patel PS, Sharp SJ, Luben RN, Khaw KT, Bingham SA, Wareham NJ, Forouhi NG. Diabetes Care. 2009 Oct;32(10):1857-63. Epub 2009 Jul 10. PMID: 19592633 doi: 10.2337/dc09-0116 CONCLUSIONS Total, white, and oily fish consumption may be beneficial for reducing risk of diabetes, reinforcing the public health message to consume fish regularly. Greater shellfish intake seems to be associated with an increased risk of diabetes, warranting further investigation into cooking methods and mechanisms. In summary, we report that specific types of fish intake are differentially associated with the risk of diabetes. Total intake of both white fish and oily fish was associated with a lower risk of diabetes, reinforcing the public health message to consume fish regularly. Shellfish intake was associated with an increased risk of diabetes, which highlights the potential importance of seafood preparation and cooking methods. The increased risk of diabetes with shellfish intake requires further study.

Association between 25-hydroxyvitamin D levels and cognitive performance in middle-aged and older European men. Lee DM, Tajar A, Ulubaev A, Pendleton N, O'Neill TW, O'Connor DB, Bartfai G, Boonen S, Bouillon R, Casanueva FF, Finn JD, Forti G, Giwercman A, Han TS, Huhtaniemi IT, Kula K, Lean ME, Punab M, Silman AJ, Vanderschueren D, Wu FC; EMAS study group. J Neurol Neurosurg Psychiatry. 2009 Jul;80(7):722-9. Epub 2009 May 21. PMID: 19460797 doi:10.1136/jnnp.2008.165720 Conclusion: In this study, lower 25(OH)D levels were associated with poorer performance on the DSST. Further research is warranted to determine whether vitamin D sufficiency might have a role in preserving cognitive function in older adults.

"High serum selenium associated with elevated LDL and total cholesterol By Helen Albert 21 January 2010 Atherosclerosis 2009; Advance online publication MedWire News: High levels of serum selenium are associated with elevated total and low-density lipoprotein (LDL) cholesterol, report US researchers. The results add weight to those of a previous UK study, reported by MedWire News, that reported an association between high plasma selenium and an adverse lipid profile. Eliseo Guallar (Johns Hopkins University Bloomberg School of Public Health, Baltimore, Maryland) and colleagues carried out a cross-sectional analysis of 1159 individuals aged 56.8 years on average who participated in the National Health and Nutrition Examination Survey (NHANES) 2003-2004."
