The harmful trans isomers will disappear from the American diet
In the end it happened! The American Food and Drug Administration (FDA) is commencing work to eliminate harmful trans isomers from food products available in stores. The presence of this inglorious ingredient in food has long been a source of controversy, scientific research unambiguously indicates that its low consumption increases the risk of cardiovascular disease, diabetes and obesity. Until now, as a counter-argument for ideas to remove harmful trans fats from the market of food products, it was a firm statement that is not possible consistently raised by food concerns. The FDA’s announcement, however, shows that the way to eliminate them will eventually have to be found.
The fatty acids contained in food products that we eat differ in terms of both construction and properties. The differences on the one hand include the number of double bonds, the length of the chain, as well as the spatial configuration. In natural food products, fatty acids with a cis configuration prevail. In the food industry, however, the use of catalytic hydrogenation (hardening) of vegetable fats rich in unsaturated acids is often used to give them the desired physical properties. Unfortunately, the change in spatial configuration causes that the fatty acids friendly or neutral for our health become a threat to it.
Scientific research clearly indicates that a small share in the diet of trans industrial isomers may increase the risk of atherosclerotic cardiovascular disease, causing dyslipidemia and enhancing the production of proinflammatory cytokines. Trans fatty acids have the ability to build into phospholipids of cell membranes, altering their properties and leading to dysfunction of membrane receptors such as the insulin receptor. The effect of this is an increased risk of obesity and diabetes. There are data that suggest that route isomers also adversely affect the nervous system, which results in a decrease in mental health and even an increased risk of developing neurodegenerative diseases. A separate issue is the possible participation of these compounds in the process of carcinogenesis … more
