Trans Fats What are they? Where are they found? Where are they found? What’s the hype? What’s the hype? Is there reason to be concerned? Is there reason to be concerned?
What are they? Trans fats for the most part are oils that have been chemically treated with hydrogen creating a “new” chemical structure thus changing both the chemical & physical properties. These fatty acids are chains of carbon atoms which combine with other molecules. This is a manufacturing process called hydrogenation. Actually the liquid oil can be made more viscous to a point where the oil becomes a solid. hydrogenation. Actually the liquid oil can be made more viscous to a point where the oil becomes a solid.
Let’s Discuss Fats First Let’s Discuss Fats First There are THREE BASIC CLASSIFICATIONS There are THREE BASIC CLASSIFICATIONSSaturatedMonounsaturatedPolyunsaturated All fats are identified as fatty acids that are recognized by the chemical formula. The molecule of fat is totally filled with hydrogen making it a “saturated” molecule. When the molecule of fat has only one available space for hydrogen it is known as a “monounsaturated” fat. And… if there are more than one availability for hydrogen, the fat is known as a “polyunsaturated” fat.
So now what? How can I tell which is which? Let’s take a look at a few sample fats & oils. Saturated Monounsaturated Polyunsaturated
Where are they found? Cakes Cookies Crackers Pies Processed Foods Fast Foods Fried Foods
So What’s the Hype Trans fats have been about for about 100 years. So what’s up all of a sudden? Trans fats are mostly unsaturated so isn’t that a nutritive improvement? Trans fats improve the flavor & texture of foods. Trans fats have a longer shelf life than the oils or animal fats. Trans fats maintain high temperatures for frying without burning.
Is there reason for concern? In 1990 scientists discovered a relationship between trans fats & cholesterol. Raises the LDL Raises the LDL Lowers the HDL Lowers the HDL These two conditions significantly increase the chance of heart disease. 1. making the arteries more rigid 1. making the arteries more rigid 2. causing major clogs in the arteries 2. causing major clogs in the arteries 3. creating insulin resistance 3. creating insulin resistance 4. actually cause or contribute to type 2 diabetes. 4. actually cause or contribute to type 2 diabetes.
In January 2006 the US government requires all manufacturers to list the trans fat content on the nutrition labels. At this time it is recommended that we only intake 1-2 grams per day of trans fat. When is Zero not Zero? Absolutely YES!! We are on the right track but must be active consumers and citizens for a healthier you.
