Coenzyme Q10. Bonakdar RA, Guarneri E. Am Fam Physician. 2005 Sep 15;72(6):1065-70. Review. PMID: 16190504 Coenzyme Q10 is a vitamin-like substance used in the treatment of a variety of disorders primarily related to suboptimal cellular energy metabolism and oxidative injury. Studies supporting the efficacy of coenzyme Q10 appear most promising for neurodegenerative disorders such as Parkinson's disease and certain encephalomyopathies for which coenzyme Q10 has gained orphan drug status. Results in other areas of research, including treatment of congestive heart failure and diabetes, appear to be contradictory or need further clarification before proceeding with recommendations. Coenzyme Q10 appears to be a safe supplement with minimal side effects and low drug interaction potential.

Dietary protein and bone health: a systematic review and meta-analysis. Darling AL, Millward DJ, Torgerson DJ, Hewitt CE, Lanham-New SA. Am J Clin Nutr. 2009 Nov 4. [Epub ahead of print] PMID: 19889822

Safety of vitamin D3 in adults with multiple sclerosis. Kimball SM, Ursell MR, O'Connor P, Vieth R. Am J Clin Nutr. 2007 Sep;86(3):645-51. PMID: 17823429 Conclusions: Patients' serum 25(OH)D concentrations reached twice the top of the physiologic range without eliciting hypercalcemia or hypercalciuria. The data support the feasibility of pharmacologic doses of vitamin D3 for clinical research, and they provide objective evidence that vitamin D intake beyond the current upper limit is safe by a large margin.

Metabolic effects of conjugated linoleic acid in humans: the Swedish experience. Riserus U, Smedman A, Basu S, Vessby B. Am J Clin Nutr. 2004 Jun;79(6 Suppl):1146S-1148S. PMID: 15159248 CONCLUSIONS CLA and specifically the isolated isomers are interesting model fatty acids for studies of the effects of (structural differences of) unsaturated fatty acids in humans. Today, there is no clear indication for human use of CLA concentrates. The possible importance of the small reduction of body fat after supplementation with the commercially available CLA products, without evidence of an associated improvement in the metabolic profile, has to be weighed against the apparent reduction of HDL cholesterol and an increased lipid peroxidation. The possible health consequences of prolonged treatment periods are at present unknown. Human supplementation with high doses of the trans-10,cis-12 CLA isomer should be avoided while awaiting further information on possible effects and side effects. However, it cannot be excluded that future studies could point to clinical applications, eg, as a result of antitumorigenic properties or as a tool to prevent weight gain. This possibility certainly requires more research to increase the understanding of the mechanisms behind the effects of CLA and specific CLA isomers on a molecular level. More controlled studies in defined populations are needed, as are controlled studies for comparisons of the effects of different and well-defined (mixtures of) isomers and human studies of longer duration to secure long-term effects and safety.

Effects of cis-9,trans-11 conjugated linoleic acid supplementation on insulin sensitivity, lipid peroxidation, and proinflammatory markers in obese men. Riserus U, Vessby B, Arnlov J, Basu S. Am J Clin Nutr. 2004 Aug;80(2):279-83. PMID: 15277146 CONCLUSIONS: A CLA preparation containing the purified c9,t11 CLA isomer increased insulin resistance and lipid peroxidation compared with placebo in obese men. Because c9,t11 CLA occurs in commercial supplements as well as in the diet, the present results should be confirmed in larger studies that also include women.

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).

Opposing effects of cis-9,trans-11 and trans-10,cis-12 conjugated linoleic acid on blood lipids in healthy humans. Tricon S, Burdge GC, Kew S, Banerjee T, Russell JJ, Jones EL, Grimble RF, Williams CM, Yaqoob P, Calder PC. Am J Clin Nutr. 2004 Sep;80(3):614-20. PMID: 15321800 Conclusion: Divergent effects of cis-9,trans-11 CLA and trans-10,cis-12 CLA appear on the blood lipid profile in healthy humans: trans-10,cis-12 CLA increases LDL:HDL cholesterol and total:HDL cholesterol, whereas cis-9,trans-11 CLA decreases them.

Effects of dairy products naturally enriched with cis-9,trans-11 conjugated linoleic acid on the blood lipid profile in healthy middle-aged men. Tricon S, Burdge GC, Jones EL, Russell JJ, El-Khazen S, Moretti E, Hall WL, Gerry AB, Leake DS, Grimble RF, Williams CM, Calder PC, Yaqoob P. Am J Clin Nutr. 2006 Apr;83(4):744-53. PMID: 16600923 CONCLUSION: Dairy products naturally enriched with cis-9,trans-11 CLA and trans-11 18:1 do not appear to have a significant effect on the blood lipid profile

Conjugated linoleic acid supplementation for 1 y does not prevent weight or body fat regain. Larsen TM, Toubro S, Gudmundsen O, Astrup A. Am J Clin Nutr. 2006 Mar;83(3):606-12. PMID: 16522907 CONCLUSION: A 3.4-g daily CLA supplementation for 1 y does not prevent weight or fat mass regain in a healthy obese population.

A vitamin D nutritional cornucopia: new insights concerning the serum 25-hydroxyvitamin D status of the US population. Norman AW. Am J Clin Nutr. 2008 Dec;88(6):1455-6. PMID: 19064502 doi:10.3945/ajcn.2008.27049 In summary, the report of Looker et al should be required reading for all nutritionists, clinicians, and vitamin D aficionados who are decision makers with regard to 25(OH)D assays, vitamin D nutritional policy, and the care of patients with vitamin D-related diseases.

Types of dietary fat and risk of coronary heart disease: a critical review. Hu FB, Manson JE, Willett WC. J Am Coll Nutr. 2001 Feb;20(1):5-19. Review. PMID: 11293467

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.
