Trans fats would be the unhealthiest from all fats in a modern diet – it is so called processed fats. It is a kind of fats that we can‘t find in the nature, but can find in processed food.
Trans fat definition Trans fatty acids form, when vegetable oil becomes hard and it converts into margarine. Trans fatty acids are aplenty in margarine and there where last mentioned compound is used – in roasted food, horsd’oeuvres, fast food. We can diagnose availability of trans fats just in laboratory research. This is because fats become trans fats at the time of operational process – hydrogenization – in industry, like a lateral product of this process. Hydrogenization of natural fats, mostly of different vegetable oils, was introduced at the beginning of 20th century. Industrialists noticed that heating oils and volatilizing a particular quantity of their volume, obtained oils dissolve in higher temperature and food, made with these oils, spoils slower. Food with trans fat is cheaper than natural fats as butter or grease.
Ban trans fats Recently a law was enacted in the USA. It binds all producers of food to declare processed fats content, being in their made food, but this law hasn’t passed yet. In the concrete, it will become operative from the July 1, 2008. And from July 1, 2007 all restaurants of the New York City will have to withdraw oils with trans fat from circulation, but they still will be able to market other articles of food, containing trans fat. Unless the researches of scientists, many customers would never know about harmful matters in their food – food with trans fat doesn’t differ from food without trans fat.
Trans fat in food and diseases Trans fatty acids motivate atherosclerosis, because it increases cholesterol concenration in blood. Trans fatty acids don’t have to total over 2% of value of energy of daily dietary. Even little stock of trans fatty acids can bring on disorders of fecundity. Women, who are going to conceive, should steer clear of this kind of food not just for their forms and health, but for that trans fat can bring on serious disorders of fecundity. Scientists of Harvard school of public health in Boston explored the bigger stock of trans fat is in woman’s menu the bigger probability of discomfiting of her cycle of fecundity. If 2% of daily calories, which we get from carbohydrates, would be changed to trans fat, risk, that fecundity will discomfit, graduates to 73%. If we replaced 2% of daily calories that we would get from omega-6 polyunsaturated fatty acids, to trans fats, hazard would add up to 79%. Woman who gets 1800 kcal per day, 2% of calories is 4 g of trans fat. Trans fats immediately bring on heart diseases, type 2 diabetes and actuate obesity. It hasn’t agreed yet whether trans fat immediately brings on cancer, but there are some research works, tending to agree with this hypothesis. Nowadays every from us should read carefully tags on alimentary products. Pay attention to the word “hydrogenated” or “partially hydrogenated”. Trans fatty acids work like a surplus of saturated fatty acids – it means, these acids induce atherosclerosis, heart and blood vessels diseases, increase mortality from them. Dieticians recommend using as less artificial trans fats. Also they recommend getting no more like 35% of fats together with daily food, and not so many as 10% of daily calories should compose saturated fats. |
