Each fat molecule (triglyceride) consists of a glycerol molecule connected to 3 fatty acids. All glycerol molecules are very identical, but there are dozens and dozens of different fatty acids in the nature and the health effects vary among them.
Saturated fatty acids have no double bonds, monounsaturated have just you (mono = 1) and polyunsaturated fatty acids have a variety of double bonds (poly = many). Here's the essential aspects. The double bonds are unstable when heated and they have a propensity to react with oxygen.
Therefore, the longer double bonds in a fatty acid molecule has the more unstable it is going to be used for cooking. This is the reason saturated fats (zero double bonds) these as coconut-oil are incredibly resistant to heat.
Although most vegetable oils contain polyunsaturated fatty acids having a handful of double bonds, Olive Oil contains mostly monounsaturated fatty acids with one double bond. As a outcome, having one double bond in the fatty acid gland is maybe not a dreadful point. It is merely the polyunsaturated fatty acids (such as those in soybean and canola oils) that can get harmful. Oils are usually a variety of a variety of fatty acids.
Olive Oil, for example, is 7 3 percent monounsaturated, 1-1% polyunsaturated and 14 percent saturated. In other words, the heat resistant monounsaturated and saturated fats make up 87 percent of olive oil. Olive Oil contains predominantly monounsaturated fatty acids that are actually rather resistant to heating. Damage-prone polyunsaturated fats make up just about 11% of Olive Oil.
Research shows that a diet rich in olive oil may be able to actually slow down the aging of the heart. It is a known fact that as we grow older the heart also goes through a normal aging process. The arteries may not function as well as they did and this can eventually lead to a number of health problems.
However, in a recent study, Spanish researchers from the Lipids and Atherosclerosis Research Unit of the Reina Sofia University Hospital in Cordoba, found out that a diet rich in olive oil or other monounsaturated fats could indeed improve the arterial function of elderly people.The study published in the American Journal of Clinical Nutrition, compared the effect of a Mediterranean style diet rich and vibrant in Olive Oilwith that of a low fat high carbohydrate diet and a diet rich in saturated fats and came to a conclusion that the diet rich in olive oil resulted in bringing down endothelial damage and dysfunction. The endothelium is a layer of cells that line the inner walls of the arteries and help the blood circulate smoothly.
When the endothelium is damaged as a result of us aging, it releases endothelial microparticles. In this study the researchers measured the number of these microparticles as well as another type of cell, which replaces damaged endothelial cells.
The results showed that when healthy elderly participants followed the Mediterranean diet rich in olive oil, they had a lower number of the damaging microparticles and higher concentrations of the cells that replace damaged endothelial cells compared with the other two diets.
Tese measurements suggest that the endothelium of blood vessels are less affected by the deterioration associated with age when following a Mediterranean diet that is based on olive oil.
Although the study was fairly small — it involved 20 healthy elderly individuals — it’s the first to sustain similar results associating the Mediterranean diet with the circulatory system of the elderly, according to a statement from the hospital.
