Approaches to removing trans fats from the food supply in industrialized and developing countries
A number of approaches have been initiated by governmental and public health organizations in different countries to reduce trans-fatty acid (TFA) intakes. These have included nutrition recommendations with regard to TFAs and general nutrition recommendations regarding the selection of healthy fats, programmes to raise awareness about the adverse effects of TFAs through nutrition and health claims, voluntary or mandatory labelling of the trans content of foods, voluntary or legislated programmes to encourage or force industry to reformulate food products to remove TFAs, the promotion of health and agricultural policies that encourage the production of healthy alternatives to trans fat and finally, mandatory regulation of food standards to remove or reduce the TFA content. This paper reviews a number of initiatives to reduce the intake of TFAs underway in selected industrialized and developing countries, which serves to illustrate the merits and limitations of the available options and how the approaches that have been taken reflect local conditions.Facultad de Ciencias MĂ©dica

WHO scientific update on trans fatty acids: Summary and conclusions
The purpose of the WHO scientific review on trans fatty acids (TFAs) was to examine the evidence generated since the 1993 Joint FAO/WHO Expert Consultation on Fats and Oils in Human Nutrition, and to inform member countries on the health consequences of TFAs consumption that have emerged since the last report was released. The new information was deemed sufficient to recommend the need to significantly reduce or to virtually eliminate industrially produced TFA from the food supply in agreement with the implementation of the 2004 WHO Global Strategy on Diet, Physical Activity and Health. This goal has been accomplished in some countries and cities, by the virtual elimination of partially hydrogenated vegetable oils in the human food supply, replacing them with healthy cis-unsaturated fatty acids. The document provides the evidence base to promote discussion between the international scientific community related to nutrition and health as well as between agriculturalists, food producers, relevant health professionals, national and international food regulatory agencies, civil society and the private sector to achieve the stated goal.Facultad de Ciencias MĂ©dica

Vitamin and mineral supplements in pregnancy and the risk of childhood acute lymphoblastic leukaemia: a case-control study
<p>Abstract</p> <p>Background</p> <p>An earlier case-control study from Western Australia reported a protective effect of maternal folic acid supplementation during pregnancy on the risk of childhood acute lymphoblastic leukaemia (ALL). The present study tested that association.</p> <p>Methods</p> <p>A national case-control study was conducted in New Zealand. The mothers of 97 children with ALL and of 303 controls were asked about vitamin and mineral supplements taken during pregnancy.</p> <p>Results</p> <p>There was no association between reported folate intake during pregnancy and childhood ALL (adjusted odds ratio (OR) 1.1, 95% confidence interval (CI) 0.5–2.7). Combining our results with the study from Western Australia and another study from Québec in a meta-analysis gave a summary OR of 0.9 (95% CI 0.8–1.1).</p> <p>Conclusion</p> <p>Our own study, of similar size to the Australian study, does not support the hypothesis of a protective effect of folate on childhood ALL. Neither do the findings of the meta-analysis.</p

Prostate cancer risk and consumption of fish oils: a dietary biomarker-based case–control study
Experimental studies suggest that the risk of prostate cancer is reduced with the intake of long-chain n-3 polyunsaturated fatty acids derived from marine foods, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). However, few human studies have been conducted due to difficulties in assessing the dietary intake of these fatty acids. The authors examined the relationship between prostate cancer risk and EPA and DHA in erythrocyte biomarkers in a population-based case–control study in Auckland, New Zealand during 1996–1997 involving 317 prostate cancer cases and 480 age-matched community controls. Reduced prostate cancer risk was associated with high erythrocyte phosphatidylcholine levels of EPA (multivariate relative risk = 0.59; 95% confidence interval 0.37–0.95, upper vs lowest quartile) and DHA (multivariate relative risk = 0.62; 95% confidence interval 0.39–0.98, upper vs lowest quartile). These analyses support evidence from in vitro experiments for a reduced risk of prostate cancer associated with dietary fish oils, possibly acting via inhibition of arachidonic acid-derived eicosanoid biosynthesis. © 1999 Cancer Research Campaig
