grams of fat on nutrition facts label don't add up

2.8g of total fat. Of that 0.4g is saturated fat, 0.9g is polyunsaturated fat and 1g is monounsaturated fat. Adding saturated / polyunsaturated / monounsaturated yields 2.3g of total fat - not 2.8g. What's composing the remaining 0.5g of fat?
Best Answer
There are different compounds included in the "total fat" calculation, which do not belong to any of the three classifications. Most probably, the larger part of the missing 0.5g are some kinds of phospholipids.

Why don t grams on nutrition labels add up?
Why do you think this is the case? Note: Other nutrients such as sodium (salt) might be listed as well. Their mass per serving is usually expressed in milligrams (mgs). There are 1,000 milligrams in a gram, so although these nutrients are important for a healthy diet, they do not add much mass to a serving of food.How is total fat calculated on nutrition label?
Multiply the grams of saturated fat by 9 = (xx) the number of saturated fat calories in the food item. b. Divide (xx) the number of saturated fat calories in the food item by the total number of calories in the food item = % of saturated fat. 1) Fat \u2013 3 x 9 = 27 fat calories; 27/90 = 30% total fat.Why do the totals of the nutrients not add up to 100 g?
If you are asking why the number of grams of each substance doesn't add up to 100g, then that's because not all of the material in the food is accounted for. A large portion of the mass of food tends to be water, but water content is not disclosed on the label. Dried food still has water in it, just much less.Why is the percentage listed on a nutrition label not always accurate?
Unfortunately, Nutrition Facts labels are not always factual. For starters, the law allows a pretty lax margin of error\u2014up to 20 percent\u2014for the stated value versus actual value of nutrients. In reality, that means a 100-calorie pack could, theoretically, contain up to 120 calories and still not be violating the law.How to Read Nutrition Facts | Food Labels Made Easy
