How Can Foods With Partially Hydrogenated Oil Be Trans-Fat Free?

Question: How Can Foods With Partially Hydrogenated Oil Be Trans-Fat Free?

Answer: The United States Food and Drug Administration (FDA) requires trans-fats to be listed on Nutrition Facts labels of packaged foods, but only when there is more than 0.5 grams trans-fat per serving. The "per serving" is the key to the problem. If a food product has less than 0.5 grams trans-fat per serving, the label will show zero grams trans fats even if partially hydrogenated oil is one of the ingredients.

If the labels says the food is trans-fat free, but the ingredients list includes partially hydrogenated oils, then you have to figure out how many servings of the food you're actually going to eat. If you're going to eat a whole bag of chips cooked in trans-fats, then you're going to get some trans-fats. It's difficult, then, to know exactly how much trans-fat you're consuming, so it's best to choose products that don't have partially hydrogenated oils in the first place.

So what are partially hydrogenated oils, anyway? Partially hydrogenated oils are liquid poly-unsaturated fats in liquid form that are treated with hydrogen molecules to create a semi-solid texture (like some types of stick margarine) and to improve storage time for the fats. The process of hydrogenating the oil consists of forced hydrogen molecules onto the poly-unsaturated fats, which changes their chemical shape into something resembling saturated fat. The chemical change creates trans-fats, which turns out are worse for your health than saturated fats. Because of potential health issues, the amount of trans-fats must be listed on the Nutrition Facts labels, but as I stated, that can be a little deceiving.
