Focus on Trans Fat by: Jon Gestl There's no doubt--carbohydrates have taken center stage in public discourse about dietary practices. You can't turn on the TV, open a newspaper or walk past the office water cooler these days without hearing a debate about this nutrient du jour. Recently, however, increasing attention is being given to an all but forgotten part of our diet. Move over, carbohydrates: fat is making a comeback in the headlines. More specifically, trans fat. Of the four types of dietary fat (monounsaturated, polyunsaturated, saturated and trans), the focus recently has been on trans fat. Abundant in margarine, shortening, packaged baked goods and French fries to name a few, trans fat is a widely used ingredient for food manufacturers because it is cheap and contributes to increased shelf life. It is listed as 'partially hydrogenated vegetable oil' and 'vegetable shortening' on product ingredient lists. Hydrogenation is the process of heating an oil and passing hydrogen bubbles through it. The fat's density is increased, and food manufacturers use it frequently because it gives products a richer butter flavor. Saturated butter is much more expensive to use, so manufacturers reduce costs by using partially hydrogenated oils. Partially hydrogenated oils, however, have a much different effect on the body than even the demonized saturated fats. We all know that we need to limit saturated fat in our diets, but specific amounts, although small, have been deemed acceptable, and even help to facilitate a variety of processes for the body. Trans fat, however, provides no positive effects whatsoever. Studies have consistently shown that trans fat raises LDL (bad) cholesterol and lowers HDL (good) cholesterol. It contributes to clogging of the arteries and type 2 diabetes. Trans fat has also been linked to an estimated '30
