Why We Need FAT?

Saturated Fats and Trans Fats can be found in most
fast-foods and fried products.
There are lots of reasons why our bodies need fat. Firstly Fat acts as the storage system for excess calories we consume mainly from dietary fat, carbohydrates and proteins. Fats are essential ingredients used to maintain healthy skin and hair also it acts as a carrier for the transportation of fat-soluble vitamins like A,D,E and vitamin K. Dietary Fats provides us with essential fatty acids, and these fatty acids our bodies don't produce, they also help with the regulation of blood pressure and cholesterol in your body. While we need fats in our diet it is also important to identify the types of fats that can damage our cardiovascular system and clog our arteries these being Saturated Fats and Trans Fat. Saturated Fats comes mainly from animal products and dairy but also it can be found in coconut and palm oils as well. Trans Fat comes from hydrogenated vegetables oils such as margarine and vegetable shortening, you might ask what is hydrogenated vegetable oil well it is high tech process in which Vegetable seeds are cleaned and bleached to remove all colour, taste, smells and impurities. The liquid vegetable oil is then heated to high temperatures and a catalyst (commonly nickel, but could be palladium, platinum or rhodium) is added. Hydrogen is bubbled through the liquid. The mixture is then filtered to remove the metal, leaving hydrogenated vegetable oil.Water, whey, salt, vitamins, colourings, flavourings and emulsifiers may then be added to produce hydrogenated margarine. More on this topic to come until then be wise about your fats, be healthy.
