In the unsaturated fatty acids two carbon atoms are joined by a double bond, this kind of t can produce an stereochemistry isomerization, and sections of the molecule that are on both sides of the double bond may be at the same side cis isomers or on opposite sides trans isomers.

Biol Res ; In the present geasos we review the possible health risks of TFA and analyze the factors that may acids or decrease these risks. These authors determined that this ratio was decreased most effectively corresponding to decreased risk of CHD when trans FA and saturated FA were replaced with cis unsaturated FA.

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.

Trends to an increased consumption of some foods manufactured with hydrogenated fats can lead to a higher T FA intake, which has a controversial role as cardiovascular disease risk factor. Am J Clin Nutr ; Expert Panel on Trans Fatty Acids and coronary heart disease risk.

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 fatty acids PUFA content in blood of premature, in fetal tissue, umbilical blood of babies to term and plasma phospholipids in healthy children.

As we all know the diet is one of the so-called environmental factors that are better defined, and within the food, the type of fats are more closely associated with macronutrient levels and quality of plasma lipids. 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.
