Trans- isomers of fatty acids are prepared by heating liquid vegetable oil to high temperatures, in the presence of hydrogen and catalysts. This is a process known as hydrogenation.

As a result of the chemical reaction vegetable fats are hardened, as seen in margarine. The more hydrogenated the oil is, the harder it is at room temperature.

Fats taken with food are of three types - saturated, unsaturated and trans fats. Saturated fats are of animal origin and in their structure has no double bonds, so that at room temperature, they are solid.

Trans Fats

Unsaturated fats contained in the oil and olive oil have double bonds in their molecules and are liquid at room temperature.

Dangers of trans fats

Other major sources of harmful fats are chips, semi- ready soups, biscuits, concentrated sauces, waffles, chocolates, cakes, fried potatoes at fast meals.

Trans fats naturally occur in meat and dairy products. The higher fat content of these products, the higher are the levels of trans fats.

In some U.S. states the use of trans fats for cooking in restaurants is prohibited. The European Union recommends noting the contained trans fats in products and possible ban of artificial trans fats. When checking the label, and look not only for hydrogenated, but also for partially hydrogenated oils.

Trans fats are widely used because they are cheap and have high durability. There is no law that requires mandatory display of the exact weights of the contained trans fats on the information list. On the other hand, they often pass under the general designation of vegetable oils.

Artificial trans fats

Trans fats should be replaced with foods that are cooked in olive oil, sunflower, linseed and soybean oil. Olive oil is the most useful because it is rich in monounsaturated fat. Virgin olive oil has many health benefits.

Generally, your intake of processed and fried foods should be limited. The intake of animal fat should be reduced too.

According to the American Heart Association, the consumption of trans fats must be kept to less than 1% of total calorie intake for a day.
