fats for energy intensity has no equal.However, the supply of energy in the body of the exchange - is not their only function.They act as solvents for the fat-soluble vitamins (A, D, E, K) are involved in the absorption of nutrients in the small intestine, part of the nerve cells (human brain is more than half consists of fat cells) and hormone therefore overemphasizedtheir significance.
well as serve as a source of essential (essential) fatty acids) (EFAs), which include those distinguish 5 of polyunsaturated fatty acids (PUFAs):
- linoleic
- linolenic
- arachidonic
- eicosapentaenoic
- docosahexaenoic
body is able to synthesize them in very small quantities.The latter are essential as precursors leykotrientov, prostaglandins and thromboxanes, which function as "local hormones."
number of essential fatty acids in the body depends on how many of fats and oils person eats.Fatty acids - basic building blocks not only in the fat contained in human tissues, but are in foods.They are an important source of energy for all the body.Essential fatty acids to occupy most part of the containment or membranes surrounding every cell.
Daily demand for them is 10-20% of total calories derived.Lack of these substances poses a serious threat to health.However, many experts believe that about 80% of our population consumes insufficient essential fatty acids.
in dietary literature and on product packaging can find information about fatty acids "Omega".The fact that there are two main classes of polyunsaturated fatty acids (PUFAs) - omega-6 and omega-3 and one main class of monounsaturated fatty acids (MNZHK) - omega-9.
to omega-3 - fatty acids include a-linolenic, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are present mainly in fish, and also in small quantities, can be synthesized in the body from a-linolenic acid.On them above.Low levels of EPA and DHA in the diet can cause serious health problems - affect the functioning of the eye and the brain.Also, these substances help cope with inflammatory processes, such as arthritis, may reduce triglycerides in the blood, which are directly associated with heart disease and stroke.
Monounsaturated fats contain unsaturated fatty acid with one double bond - omega-9.The most important of monounsaturated fatty acids in the diet is oleic acid.It is present in the cell membranes of animals and plants, and helps to maintain arterial elasticity and skin.MNZHK stable at high temperatures (and therefore well suited for frying olive oil).Sources of exposure: olive and almond oil.
characteristic signs and symptoms inherent deficiency of omega-9 fatty acids: the aggravation of cardiovascular diseases, high blood pressure, joint pain, arthritis, poor digestion, constipation, decreased immunity, frequent colds, sore throat, depression, confusion, memory impairment, fatigue, malaise, dry skin, brittle (cracked) nails, dry, lifeless hair, dry mucous membranes, tear ducts, mouth, vagina.
In Mediterranean countries, where the food consumed a large amount of olive oil, olives, avocados and nuts are relatively rare cases of cardiovascular diseases and cancer.To a large extent this is attributable to the omega-9 fatty acids present in all of these foods.
