The new U.S. Food and Drug Administration (FDA) food labeling rules allow food manufacturers to list “zero” grams of trans fat (hydrogenated fat) on a food label when the amount of trans fat is less than .5 grams. If you eat several foods a day with under .5 grams of trans fats, you could be consuming several grams of trans fat. If you want to avoid foods with trans fats, check the ingredients listed on the label to see if a “hydrogenated” fat is listed. Like saturated fats, trans fats can raise the risk of heart disease by increasing the levels of LDL (“bad”) cholesterol in the blood.
