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.

Hence, its effect on the lipoproteic profile is at least as unfavourable as that of saturated 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.


Several human studies have shown no significant effects of interesterified fats on blood lipid parameters. Si continua navegando, consideramos que acepta su uso. Trans fatty acids and coronary heart disease.

The lowest amounts were found in raw olive and sunflower oils 0. One of the latest reviews on the trans fatty acids and its possible effects on cardiovascular disease has been conducted by Mozaffarian et al. Trans fatty acids and nutrition. The main side effect of this transs is the formation of geometric and positional isomers of the unsaturated fatty acids, primarily trans isomers of fatty acids TFA.

The antiproliferative effects of biologically active isomers of conjugated linoleic acid on human colorectal and prostatic cancer cells. 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 tran children in trxns.

During the technological manipulation of vegetable oils, in order to transform them into more stable products it is applied the process of hydrogenation. But evaluating our results of t FA at different levels of usual food consumption, we fear that these values are higher at present, acdios in the younger population strata of our society children and adolescents. Effects of dietary fatty acids and the carbohydrates on the ratio of serum total to HDL cholesterol and on serum lipids and apolipoproteins: 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.

N Engl J Med,pp. Indeed, taking into account that the main trans isomer which is cited in these foods is the trans isomer of oleic acid called elaidic acid C Besides, trans fats appears to increase the risk of CHD more than any other macronutrient, conferring a substantially increase risk at low levels of consumption 1 to 3 percent of total energy intake. In humans, the consumption of trans fat increases plasma activity of cholesteryl ester transfer protein, the main enzyme for the transfer of cholesterol esters from HDL to LDL and very low – density lipoprotein VLDL.

Because of these findings, scientific and health-related organizations currently recommend limited intake of TFA. Conclusions – Currently the most likely source of trans fatty acids in food are hydrogenated fats. Am J Clin Nutr, 73pp.
