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.

Conjugated linoleic acid impairs endothelial function. Taylor JS, Williams SR, Rhys R, James P, Frenneaux MP. Arterioscler Thromb Vasc Biol. 2006 Feb;26(2):307-12. Epub 2005 Dec 8. PMID: 16339498 CONCLUSIONS: A CLA isomeric mixture had at most modest effects on adiposity and worsened endothelial function. On the basis of these results, the use of the isomeric mixture of CLA as an aid to weight loss cannot be recommended

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.

The effect of vitamin D2 and vitamin D3 on intestinal calcium absorption in Nigerian children with rickets. Thacher TD, Obadofin MO, O'Brien KO, Abrams SA. J Clin Endocrinol Metab. 2009 Sep;94(9):3314-21. Epub 2009 Jun 30. PMID: 19567516 Conclusions: Despite similar increases in 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D with vitamin D2 or vitamin D3, fractional calcium absorption did not increase, indicating that rickets in Nigerian children is not primarily due to vitamin D-deficient calcium malabsorption

Is a lower dose of vitamin D supplementation enough to increase 25(OH)D status in a sunny country? Pignotti GA, Genaro PS, Pinheiro MM, Szejnfeld VL, Martini LA. Eur J Nutr. 2009 Nov 28. [Epub ahead of print] PMID: 19946776 CONCLUSION: The dose given (400 IU/day) was not enough to achieve 25(OH)D concentration, considered optimal for bone health.

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.

Eggs modulate the inflammatory response to carbohydrate restricted diets in overweight men. Ratliff JC, Mutungi G, Puglisi MJ, Volek JS, Fernandez ML. Nutr Metab (Lond). 2008 Feb 20;5:6. PMID: 18289377 Carbohydrate restricted diets (CRD) consistently lower glucose and insulin levels and improve atherogenic dyslipidemia [decreasing triglycerides and increasing HDL cholesterol (HDL-C)]. We have previously shown that male subjects following a CRD experienced significant increases in HDL-C only if they were consuming a higher intake of cholesterol provided by eggs compared to those individuals who were taking lower concentrations of dietary cholesterol. Here, as a follow up of our previous study, we examined the effects of eggs (a source of both dietary cholesterol and lutein) on adiponectin, a marker of insulin sensitivity, and on inflammatory markers in the context of a CRD. Conclusion A CRD with daily intake of eggs decreased plasma CRP and increased plasma adiponectin compared to a CRD without eggs. These findings indicate that eggs make a significant contribution to the anti-inflammatory effects of CRD, possibly due to the presence of cholesterol, which increases HDL-C and to the antioxidant lutein which modulates certain inflammatory responses.

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.

Egg consumption and endothelial function: a randomized controlled crossover trial. Katz DL, Evans MA, Nawaz H, Njike VY, Chan W, Comerford BP, Hoxley ML. Int J Cardiol. 2005 Mar 10;99(1):65-70. PMID: 15721501 Conclusion: Short-term egg consumption does not adversely affect endothelial function in healthy adults, supporting the view that dietary cholesterol may be less detrimental to cardiovascular health than previously thought

Dietary cod protein improves insulin sensitivity in insulin-resistant men and women: a randomized controlled trial. Ouellet V, Marois J, Weisnagel SJ, Jacques H. Diabetes Care. 2007 Nov;30(11):2816-21. Epub 2007 Aug 6. PMID: 17682120 CONCLUSIONS - Dietary cod protein improves insulin sensitivity in insulin-resistant individuals and thus could contribute to prevention of type 2 diabetes by reducing the metabolic complications related to insulin resistance.

Dietary cod protein reduces plasma C-reactive protein in insulin-resistant men and women. Ouellet V, Weisnagel SJ, Marois J, Bergeron J, Julien P, Gougeon R, Tchernof A, Holub BJ, Jacques H. J Nutr. 2008 Dec;138(12):2386-91. PMID: 19022962 Therefore, these results show that CP can lower hsCRP, a marker of inflammation associated with insulin resistance and type 2 diabetes.

Consumption of cod and weight loss in young overweight and obese adults on an energy reduced diet for 8-weeks. Ramel A, Jonsdottir MT, Thorsdottir I. Nutr Metab Cardiovasc Dis. 2009 Dec;19(10):690-6. Epub 2009 Apr 8. PMID: 19356912 Conclusion A dose-response relationship between cod consumption and weight loss during an 8-week energy restriction diet is found and 5×150g cod/week results in 1.7kg greater weight loss in young overweight or obese adults than a isocaloric diet without seafood

Omega-3 fatty acids in major depressive disorder. A preliminary double-blind, placebo-controlled trial. Su KP, Huang SY, Chiu CC, Shen WW. Eur Neuropsychopharmacol. 2003 Aug;13(4):267-71. Erratum in: Eur Neuropsychopharmacol. 2004 Mar;14(2):173. PMID: 12888186 From the preliminary findings in this study, omega-3 PUFAs could improve the short-term course of illness and were well tolerated in patients in major depressive disorder.

Separate effects of reduced carbohydrate intake and weight loss on atherogenic dyslipidemia -- Krauss et al. 83 (5): 1025 -- American Journal of Clinical Nutrition Changes in peak LDL diameter (Table 2) and mass concentrations of LDL subfractions (Table 3) induced by each of the diets were reflected by changes in the proportions of subjects exhibiting LDL subclass pattern B (Figure 2). There were linear reductions in the prevalence of pattern B as a function of reduced carbohydrate intake after both the stable-weight and weight-loss periods. However, the slopes of these relations differed (P = 0.04) such that the magnitude of the reduction in expression of pattern B induced by weight loss increased in association with the percentage of carbohydrate intake. Conclusions: Moderate carbohydrate restriction and weight loss provide equivalent but nonadditive approaches to improving atherogenic dyslipidemia. Moreover, beneficial lipid changes resulting from a reduced carbohydrate intake were not significant after weight loss.
