All About Fats Good To Know

With the low carbohydrate craze, many people have turned their attention to fats. They eat more of it and think it is fine. Depending on what kind of fat you are consuming and how much of it you take in, fats can be beneficial or harmful to your health.

There are three main types of fat. They are saturated, unsaturated and trans fats. Saturated fats come mainly from animal sources such as meat and dairy. FatsAt room temperature, saturated fats are solid. Unsaturated fats come mainly from plant sources such as olives and nuts and contain no cholesterol. They are liquid (oil) at room temperature. Unsaturated fats are broken down further in monounsaturated (one double bond) and polyunsaturated (more than one double bond).

You might be asking yourself what a fat is saturated or unsaturated with. A fat molecule (without getting into too much chemistry) is made up of carbon atoms that have hydrogen atoms attached to them.

In saturated fats, all carbon atoms have a single bond to another carbon atom and are also bonded to hydrogen atoms. In unsaturated fats, not all carbons are saturated with hydrogens so double bonds form between carbons. Depending on what carbon the double bond is formed determines the fat’s properties.

Trans fat is man-made fat. It is made by taking an unsaturated fat and putting hydrogen through it in a process called hydrogenation. The purpose is to transform the liquid fat into solid fat at room temperature. Trans fat is very bad for your health. Whereas, whole saturated fat increases LDL (bad) cholesterol slightly, while it significantly increases HDL (good) cholesterol.

Trans fat, however, increases LDL cholesterol and decreases HDL cholesterol. Trans fat is the cause of many chronic diseases. See the labels of packaged foods before you buy it.  If the ingredients shows hydrogenated oil or partially hydrogenated oil, avoid it like a plague.

Several studies, both epidemiological and clinical, have demonstrated that saturated fat is beneficial to our health. This is contrary to the prevailing theory that fat is linked to heart disease and other chronic diseases. The details are brilliantly explained in the book, “The Big Fat Surprise”, written by Nina Teicholz. It is available in digital format at Amazon.
