The Food and Drug Administration announced the preliminary determination that partially hydrogenated oils, or PHOs, are not “generally recognized as safe” for use in food. PHOs are the main source of trans-fats in processed food and cause the body to produce more low-densitylipoprotein, or “bad cholesterol,” which increases the risk of coronary heart disease. The stigma of trans-fat over the past few years has already prompted manufactures and retailers to significantly decrease levels in many foods. But what you think is trans fat free, may not necessarily be. A loophole allows such labeling if the product contains .5 grams or less of trans fat. The FDA isn’t the first to wage war on PHOs. Policies enacted in Costa Rica, the Netherlands, Brazil, Denmark and South Korea have been important in decreasing trans-fat consumption.
