FOODS RICH IN TRANS FATS: PROMOTE MEMORY PROBLEMS




Supplements for cardiovascular fitness





A trans fatty acid (or trans fat) is an unsaturated fatty acid, that is, that contains one or more double bonds of trans isomerism between two carbon atoms.

Some research has found a relationship between diets containing many trans fats and coronary heart disease and atherosclerosis. It was recently published a study in which there is a significant correlation between the use of trans fatty acids and cerebral ischemic events (stroke) in women after menopause.

Trans fats are lipid molecules recognized as harmful. Are naturally present in some foods (in particular in the milk and derivatives and some meats), but in reduced concentrations compared to those of industrial products. The latter are often called hydrogenated fats. By means of the hydrogenation process, performed the food industries, it breaks artificially the double bond and the hydrogen is added, obtaining products in which the proportion of the trans form is very high. During the hydrogenation, according to need, is chosen the specific consistency of hydrogenated fat (there are different levels of hydrogenation).

  
   
    
Found in copious amounts of processed foods, trans fats are pro-oxidant compounds that may have a deleterious impact on energy cell.

Beatrice A. Golomb, MD, Ph.D., of the University of California / San Diego (California, USA), and colleagues studied 1,018 men aged between 20 years and 45 years, and in post-menopausal women without the disease coronary. The subjects completed a survey to determine the dietary intake of trans fats; the researchers gave them a test of word recall standardized.

Among men under 45 years, those who ate the most trans fats showed the worst performance in the memory test / word, with every extra gram of trans fat consumed daily associated with an estimate of 0.76 fewer words correctly recalled. For those who consumed the highest amounts of trans fat, this has resulted in about 11 words less (with a reduction of over 10% of the terms mentioned) than adults who ate small amounts of trans fats.

The study's authors argue that: "Large amounts of trans fats are significantly associated with a significant reduction in memory, in adults aged between 20 and 45 years old, often critical years for the construction of the career."
