Sneaky trans fat. You could be consuming it without even knowing that it's lurking in your food choices. We can do our best to keep an eye on products that likely contain trans fat, like cake mixes, chips and crackers, fast food, and packaged cookies and candy, but the printed nutritional data doesn't always tell the whole story.
When a package pronounces that something is trans-fat-free, it does not mean there's zero trans fat — it means the product contains less than .5 grams per serving. Because these are the sneaky facts, it's important to look beneath the nutritional data to the list of ingredients. You can assume that food contains trans fat if the ingredients include any of the following: shortening, partially hydrogenated vegetable oil, or hydrogenated vegetable oil. Be mindful of how much you're eating of foods containing these ingredients, because those smaller amounts of trans fat can add up.
