We know research shows that reducing trans fat in the American diet helps The primary dietary source for trans fats in processed food is “partially hydrogenated oils. Trans fats raise your bad (LDL) cholesterol levels and lower your good. Peanut butter contains a tiny amount of partially hydrogenated oil This inflammatory food ingredient raises your bad cholesterol (LDL) while. This is where the term “trans fat” originates. Hydrogenation also has the technical advantage of making foods solid or partially solid at room.

Polyunsaturated fatty acids have more than one double bond in the carbon chain and therefore more than one pair of hydrogen atoms. Polyunsaturated oils and fats are typically liquid at room temperature and in the refrigerator. What are trans fatty acids? Trans fatty acids are unsaturated fatty acids that have at least one double bond in the trans configuration.

While most unsaturated fatty acids in foods have the cis configuration, trans fatty acids may also be present. Trans fatty acids in foods originate from three main sources: Bacterial transformation of unsaturated fatty acids in the rumen of ruminant animals. They can subsequently be present in the meat and milk of the animal Hydrogenation and deodorization of unsaturated vegetable oils or occasionally fish oils high in polyunsaturated fatty acids During the heating and frying of oils at high temperatures Unsaturated fatty acid trans Q.

How much trans fatty acid is in food? The TFA content of bakery products rusks, crackers, pies, biscuits, wafers etc. However, surveys have shown that levels of TFAs appear to be decreasing in these products as manufacturers reformulate to remove hydrogenated oils if present.

Are trans fatty acids dangerous to eat? Since the process of hydrogenation adds hydrogen atoms to oil, it will reduce the number of unsaturated fatty acids and increase the number of saturated fatty acids in the oil.

Consumption of a high level of saturated fatty acids is associated with increasing the level of cholesterol in the blood and this may lead to coronary heart disease. Therefore, as part of a healthy diet, consumers are advised to try to lower their intake of saturated fatty acids.

Hydrogenated Oils

Sometimes partial hydrogenation is carried out on oil as this will result in a lower level of saturated fatty acids formed in the product. However, partial hydrogenation does lead to the formation of TFAs, rather than cis fatty acids. TFAs, like saturated fats are also associated with increasing cholesterol in the blood.

Although saturated fats also produce the 'good' cholesterol HDLtrans fats increase levels of the 'harmful' cholesterol LDL and decrease the good cholesterol. TFAs also lead to increased levels of triglycerides in the blood. In these respects trans fat could be considered as more likely to promote heart disease than and equivalent level of saturated fat. However, to put this in context the intake of saturated fats in the European diet is approximately 10 times that of trans fats and therefore saturated fat in the diet is still considered to present the biggest risk with respect to heart disease.

They concluded that the scientific evidence with regards to a possible relationship of TFA intake and cancer, type 2 diabetes or allergies was weak or inconsistent.

How much trans fat can I eat? The major contributors to TFA in the diets of people in these 14 countries were edible fats and ruminant fat with bakery products and French fries being additional contributing foods in some countries.

Unlike other dietary fats, trans fat — also called trans-fatty acids — both raises your LDL "bad" cholesterol and lowers your HDL "good" cholesterol. A diet laden with trans fat increases your risk of heart disease, the leading killer of men and women.

Here's some information about trans fat and how to avoid it. What is trans fat? Some meat and dairy products contain small amounts of naturally occurring trans fat. But most trans fat is formed through an industrial process that adds hydrogen to vegetable oil, which causes the oil to become solid at room temperature.

This partially hydrogenated oil is less likely to spoil, so foods made with it have a longer shelf life. Some restaurants use partially hydrogenated vegetable oil in their deep fryers, because it doesn't have to be changed as often as do other oils.

Trans fat in your food The manufactured form of trans fat, known as partially hydrogenated oil, is found in a variety of food products, including: Most cakes, cookies, pie crusts and crackers contain shortening, which is usually made from partially hydrogenated vegetable oil.

Ready-made frosting is another source of trans fat. Potato, corn and tortilla chips often contain trans fat. And while popcorn can be a healthy snack, many types of packaged or microwave popcorn use trans fat to help cook or flavor the popcorn.

Foods that require deep frying — french fries, doughnuts and fried chicken — can contain trans fat from the oil used in the cooking process.

Products such as canned biscuits and cinnamon rolls often contain trans fat, as do frozen pizza crusts. Nondairy coffee creamer and stick margarines also may contain partially hydrogenated vegetable oils. Reading food labels In the United States if a food has less than 0. This hidden trans fat can add up quickly, especially if you eat several servings of multiple foods containing less than 0.
