Nelkis Circulation, 89pp. UgesKr Laegen,pp. Dietary fat intake graos the risk of coronary heart disease in women. Although the effects of t FA in the early stages of life and its possible negative consequences have not been sufficiently studied, it has been established an inverse correlation between t FA level and polyunsaturated grazos acids PUFA content in blood of premature, in fetal tissue, umbilical blood of babies to term and plasma phospholipids in healthy children. A small amount of TFA are present in natural food, but they are mainly acidls in industrial food.

Nelkis Circulation, 89pp. UgesKr Laegen,pp. Dietary fat intake graos the risk of coronary heart disease in women. Although the effects of t FA in the early stages of life and its possible negative consequences have not been sufficiently studied, it has been established an inverse correlation between t FA level and polyunsaturated grazos acids PUFA content in blood of premature, in fetal tissue, umbilical blood of babies to term and plasma phospholipids in healthy children. A small amount of TFA are present in natural food, but they are mainly acidls in industrial food.

Association between trans fatty acid intake and year risk of coronary heart disease in the Zutphen Eldely Study: September Pages Bakery food are the major dietary source of trans fatty acids among pregnant women with diets providing 30 percent energy from fat.

Eur Heart J, 17pp. Lipid, 36pp. Finally, we believe that observing the results obtained there is a great variability in the content of trans fatty acids in foods consumed by children, we need a special vigilance on the intake levels of these compounds by the general population and especially by the younger population strata of our society.

Our results also show a decrease of these compounds in some bakery products due to tranns of hydrogenated fats for edible oils.

Am J Epidemiol,pp. Voeding, 5pp. But evaluating our results of t FA at different levels of usual food consumption, we fear that these values are higher at present, especially in the younger population strata of our society children and adolescents.

At present, products labelling does not include with limited exceptions their content in trans fatty acids, which complicates their identification by consumers. Eur J Clin Nutr ; Diet and risk of type 2 diabetes; the role of types of fat and carbohydrate. Generally, the composition of fatty acids in food is one of ics methods used to assess the nutritional quality of them.

Dietary fat intake and risk of type 2 diabetes in women. Am J Clin Nutr ; In conclusion, taking into account available data, the general consensus is to moderate the consumption of trans fatty acids due to its potential adverse effects. J Am Coll Nutr, 9pp.

These compounds are formed generally during partial hydrogenation of vegetable oils, a process that converts vegetable oils into semisolid fats. The objective of this review is to evaluate the available data until now on the nutritional and clinical aspects of trans fatty acids and food sources in which they find themselves, in order to advise some dietary recommendations that may help to the consumer in general and our children in particular.

In all the web site. Am J Clin Nutr, 73pp. We can appreciate that in the manufacture of margarines, in some cases, has been replaced industrial method, replacing hydrogenated oils of yesteryear by other manufacturing methods for example the process of interesterificationwhich has affected the levels of trans fatty acids so favourable.

Nutr Cancer, 39pp. The interesterification process involves the rearrangement randomization of the FA on the glycerol backbone of the fat in the presence of a chemical catalyst or an enzyme.

One current application of this process is in the production of trans -free or low- trans fats for margarine, spread, and shortening applications.

While it is clear that all fatty acids are not equal, it is worth recalling that in general unsaturated fatty acids monounsaturated and polyunsaturated whose sources are edible oils olive, sunflower, soybean, corn and nuts almonds, hazelnutswalnuts, pine nuts, pistachios as well as fish oils rich in polyunsaturated fatty acids type w-3 are recommended, compared with less desirable saturated fatty acids present grasis animal fats and vegetable fats such as palm, coconut and palm kernel oils and the aforementioned trans fatty acids.

In Spain, food patterns have changed in recent years, especially by the increased consumption of vegetable oils and fats, having decreased consumption of animal fats. Eur J Clin Nutr, 53pp. The presence of trans isomers may be due either to natural causes, such as side effects that occur in the biological hydrogenation processes in the stomach of some animals ruminants such as cows and sheepor as a result of industrial processes, such as the refining and catalytic hydrogenation.

Esto se muestra en varias encuestas realizadas en distintas poblaciones a nivel mundial 6, 9, En cuanto al consumo de trans, se ha observado un rango considerablemente amplio de ingesta alrededor del mundo. En Estados Unidos se presentan consumos intermedios, alrededor de 6. No obstante, la evidencia sobre los trans y sus efectos nocivos sobre la salud, han superado en un margen considerable a las grasas saturadas 8, Ascherio, A et al.

The evidence of a direct link between saturated fat consumption and an increased risk of cardiovascular diseases has led consumers to consider oils derived from vegetables, and industrial products derived from them, as healthier substitutes than animal fats. During the technological manipulation of vegetable oils, in order to transform them into more stable products it is applied the process of hydrogenation. The main side effect of this process is the formation of geometric and positional isomers of the unsaturated fatty acids, primarily trans isomers of fatty acids TFA. Dietary TFA consumption has a biological and industrial origin; the latter found in margarine, shortening, home and industrial cooking oil, bakery goods, and the wide range of snack foods. The current wisdom is that TFA have an adverse effect on cardiovascular health, and its consumption poses a potential risk for increasing the incidence of heart disease.

Vukinos Firstly it should be noted that the physical properties of biological membranes depend on lipids and fatty acids graasos make up them. Currently there are more data about the effects that the intake of trans fatty acids may have on the human body in general, and its long term consequences on the metabolism in stages of growth and development of children. Diabetes mellitus y riesgo cardiovascular. While it is clear that all fatty acids are not equal, it is worth recalling that in general grzsos fatty acids monounsaturated and polyunsaturated whose sources are edible oils olive, sunflower, soybean, corn and graoss almonds, hazelnutswalnuts, pine nuts, pistachios as well as fish oils rich in polyunsaturated fatty acids type w-3 are recommended, compared with less desirable saturated fatty acids present in animal fats and vegetable fats such as palm, coconut and palm kernel oils and the aforementioned trans fatty acids. Estimated intakes in trans fatty and others fatty acids in the US population. Food intake originated from the National Food and Nutrition Survey carried out by our research team and the National Institute of Statistics in households, where the quantities of all foods and drinks consumed during one week through one year are recorded.
