Fats - harm or benefit?

Our food is a mixture of proteins, fats and carbohydrates with a small addition of trace elements and vitamins. Should we completely abandon the components that seem to us to be harmful to the body, such as fat, says nutritionist our Oleg Vladimirov.

Fats in the body bring the most calories, therefore, doctors often advise to reduce the amount of fatty foods in order to maintain a normal weight, or even better to refuse them altogether! However, not all fats are harmful (see, for example, the film "Lorenzo's Oil" about a father's treatment of his dying son!), There are some that are called useful. Healthy fats are divided into three groups: saturated, polyunsaturated, and monounsaturated hydrogen atoms.

Saturated fats at room temperature more solid source of animal products are (beef, fatty dairy products), and tropical oils (Coconut, palm), which are often used in the food industry because of its low cost and ability for a long time not to spoil, but they benefit to the body is questionable.

Unsaturated fats at room temperature, most liquid, and they are often subjected to hardening of the so-called hydrogenation. To provide the product (margarines, spreads) are more harmful than saturated fats and contain trans fatty acids which increase the risk of coronary heart disease, cardiovascular disease, cancer, Alzheimer's disease, and can lead to infertility.

Source monounsaturated fats - canola oil and walnut oil, and olive oil and peanut oil. Their main useful property - align the ratio of good and bad cholesterol while maintaining normal total cholesterol level.

Polyunsaturated fats are divided into three types, called omega 3, 6 and 9. All of them are of great benefit body, in particular, reduce chronic inflammation and improve tissue metabolism. Polyunsaturated fats are essential to the healthy person in an amount of 5 do10 g per day, their main source of vegetable oils, nuts and oily fish. Fish should be the sea, caught in cold northern waters, when it is not necessary to refuse and from canned fish in oil - they will also bring benefits to the body.

It is clear that fat, which many consider the source of all their troubles, in fact, have a mass of useful properties, however, despite their high caloric content, to exclude them from the diet is dangerous. Meals should be varied as much as possible - for the normal development and functioning of our body requires the entire spectrum of nutrients. From the excess calories can be eliminated by increasing the consumption of energy by the body, the ways it is enough: it is possible to reduce the temperature of the environment simply by opening, for example, the window, and you can make an effort and reach, finally, to the gym! It is this, not the rejection of essential fats, actually benefit the body.
