About trans fat
Trans fat is a required line on the Nutrition Facts label, stated in grams per serving. It may be left off when a serving has less than 0.5 gram of total fat and the label makes no claim about fat, fatty acids or cholesterol. Except on the simplified format, the label then says “Not a significant source of trans fat” at the bottom of the nutrient table. When it is declared, the word “trans” may be set in italics.

When can a label leave trans fat off?
A label may leave trans fat off when a serving has less than 0.5 gram of total fat and no claim is made about fat, fatty acids or cholesterol. Except on the simplified format, the label must then print “Not a significant source of trans fat” at the bottom of the nutrient table. A label in the simplified format may also leave it off when the amount rounds to zero.
How do I find out how much trans fat is in a food?
A Daily Value is a reference target, not a measurement of any particular food. To find the trans fat content of a specific ingredient or product, look it up in USDA FoodData Central, then use that amount here to see what a label would declare.
