They are hated by all and little known. In the flesh, they can be seen as white tissue; we find them in the form of butter and in the cream: it is found in almost everything we eat, both in animal foods such as legumes and cereals. They represent a problem for humans because they contain calories and when stored they are converted into adipose tissue.

However, more than demonizing them, we should know a little more about them to moderate their consumption in our diet .

Lipids are known in the following physical states: liquids and solids. From the chemical perspective, fats are fatty acids and triglycerides. Its composition has a lower density than water, so it helps to fulfill some physiological functions in the human organism.

As food they give flavor and texture; also provide an energy reserve of 9 kilocalories per gram; carry liposoluble proteins and vitamins; produce hormones; protect our body and internal organs; regulate blood pressure; keep skin and hair healthy; benefit brain function, especially children; help cell membranes and nerves; also fight against bad cholesterol, menopause, heart disease and some types of cancer.

Animal products are considered to be harmful to health, as are all modified fats, while those of vegetable origin require for the proper functioning of the organism. Here are the types of fats that we can find

Unsaturated fats (monounsaturated and polyunsaturated)

These are formed by unsaturated fatty acids: oleic or palmitoleic. And they are divided into monosaturated and polyunsaturated. In general, they are in liquid form. They are of natural origin and, therefore, beneficial to the human, because they improve the performance of the plasma lipids and contain essential nutrients. Some examples are olive oil, corn, sunflower, among others.

These fats reduce and eliminate bad cholesterol and raise lipoproteins suitable for good cholesterol. They have been associated with decreased risk of cancer. It has also been linked to an increase in longevity. It can be found in olive oil, avocado, sesame, Angola, some nuts, macadamia nuts and lean meat.

These vegetable fats are formed by fatty acids of the omega 3 and omega 6 series; have vitamin E and benefit from the symptoms of premenstrual syndrome and motor coordination. Fatty acids rich in omega-6 fatty acids reduce the levels of LDL and HDL lipoproteins, which are responsible for bringing cholesterol to the liver, but when there is an excess of cholesterol, they attach to the arteries. On the other hand, omega-3 series decrease plasma triglyceride levels. They are found in sunflower oil, safflower oil, fish, tuna, salmon, oilseeds and sesame seeds, in some nuts, almonds and in hazelnuts.

It is important to note that vegetable oils should not be boiled because they alter their composition. On the contrary, it is recommended to ingest it coldly so that they are beneficial for health. It is also not recommended to prepare products with fats, since, as we have seen, each food has its respective fat. And if cooking oils are to be used, it is best to use oils in the form of an aerosol.
