It's good these man-made fats are being phased out.
"Trans fat can raise your risk of heart disease because it increases your cholesterol levels, specifically the levels of LDL or bad cholesterol," Trisha Calvo of Consumer Reports said.
But many packaged foods still contain trans fat. For example, Duncan Hines Creamy Frosting has one-point-five grams in two tablespoons. And one tablespoon of Land O'Lakes Margarine has three grams. A better choice is "I Can't Believe It's Not Butter" with zero grams.
"You can't assume. You always have to check the trans fat content on the nutrition label," Trisha Calvo of Consumer Reports said.
Marie Callender's Dutch Apple Pie has three grams of trans fat per serving. Sara Lee's Apple Pie lists zero grams per serving.
And Bisquick Original has one gram of trans fat in a third of a cup, while Bisquick Heart Smart has none.
But even some foods like Crisco that list zero grams per serving may still contain trans fat, if you see in the ingredient's list "partially hydrogenated" oil.
"Manufacturers can say zero grams of trans fat on a label if a product contains less than half a gram of trans fat per serving. But there's no amount of trans fat that's good for you," Trisha Calvo of Consumer Reports said.
And if you eat a lot of these products, you could be getting a sizable amount of trans fat. Consumer Reports says trans fat isn't the only fat to watch out for. Saturated fat also is bad for your heart. So that's something else to check when you check the nutrition label.
