why is partially hydrogenated oil bad for you

Question: Do All Foods Listing Hydrogenated Oils Contain Trans Fats? While scientists dispute the benefits or hazards of saturated fats, they are at least agreed that trans fats, or partially hydrogenated oils, are harmful. To this end, the U. S. Food and Drug Administration is requiring food companies to phase out artificial trans fats by 2018, unless they can prove that their use is safe. Foods that contain trans fats have partially hydrogenated oil or hydrogenated oil listed in the ingredients. Before trans fats were required to be listed on nutrition labels, from January 2006, this was our only way of knowing whether these harmful fats were present. Yet a number of products state 0g Trans Fat or declare themselves to be trans-fat free but
still Phave these oils listed in their ingredients. How can this be? Answer: There are two reasons why foods containing hydrogenated oils may be labeled trans-fat free, or list 0g trans fats on the label.


First, items that list partially hydrogenated oils in the ingredients but contain less than 0. 5g of trans fats per serving are considered by the government to be trans-fat free. A good example of this would be commercial, which contains a tiny amount of partially hydrogenated oil to prevent separation. The problem with this definition, though, is that if you eat more than the stated serving size, those fractions of a gram add up, and you are most certainly consuming trans fats. Second, products that contain fully hydrogenated oils are trans-fat free. Let s take a closer look at hydrogenation. What isPHydrogenation? Hydrogenation is the chemical process by which liquid vegetable oil is turned into. Partially hydrogenated oils contain, or trans fats, which are thought to be more harmful than.


Trans fats raise levels of bad cholesterol and lower levels of good cholesterol. You can read more on this in my. When the liquid vegetable oil is fully hydrogenated, however, almost no trans fats remain. The resulting is even more solid, taking on a hard, waxy consistency, even at room temperature. Full hydrogenation increases the amount of saturated fat, although much of it is in the form of stearic acid, which is converted by the body to oleic acid, a monounsaturated fat, which doesn t raise levels of bad cholesterol. This makes fully hydrogenated fats less harmful than partially hydrogenated fats. When Crisco introduced its trans-fat free shortening in 2004, it contained fully hydrogenated cottonseed oil, which was blended with sunflower oil and soybean oil to soften what would otherwise be a too-hard fat.


This particular formula was discontinued as it was relatively expensive. Now, Crisco uses soybean oil, fully hydrogenated palm oil, and partially hydrogenated palm and soybean oils. To be clear: just because it is trans-fat-free doesn t mean it is. One tablespoon of trans-fat free shortening contains 110 calories, 12g of fat, 3g of which is saturated. It is cholesterol free, however. Beware: if a package simply lists hydrogenated oil, without expressly stating whether it is partially or fully hydrogenated, it may not be trans-fat free. Sometimes the terms hydrogenated and partially hydrogenated are used interchangeably. If the package clearly states that it contains fully hydrogenated oil, then it will be trans-fat free. Since stricter labeling laws came into effect, trans fats are more transparent than they used to be, and many food manufacturers continue to look for healthier alternatives for their products.


Food companies began using hydrogenated oil to help increase shelf life and save costs. Hydrogenation is a process in which a liquid unsaturated fat is turned into a solid fat by adding hydrogen. During this processing, a type of fat called is made. While small amounts of trans fats are found naturally in some foods, most trans fats in the diet come from these processed hydrogenated fats. Hydrogenated oils can affect heart health because they increase БbadБ ( ) cholesterol and lower БgoodБ ( ) cholesterol. Still, food manufacturers continue to use them Б especially partially hydrogenated oils (POH) Б to: Hydrogenated oil isnБt always easy to spot, but there are ways to spot it and avoid it.
