What foods have naturally occurring trans fatty acids?

Trans fats, or trans-fatty acids, are a form of unsaturated fat. They come in both natural and artificial forms. Natural, or ruminant, trans fats occur in the meat and dairy from ruminant animals, such as cattle, sheep, and goats. They form naturally when bacteria in these animals’ stomachs digest grass.

Does hydrogenation increase trans fat?

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.

Is oleic acid a trans fat?

The trans isomer of oleic acid is called elaidic acid or trans-9-octadecenoic acid. These isomers have distinct physical properties and biochemical properties. Elaidic acid, the most abundant trans fatty acid in diet, appears to have an adverse effect on health.

How are trans fatty acids produced in food?

Trans fatty acids are solid at room temperature and occur, in small amounts, naturally in some food. However, most of the solid fats content of trans fatty acids is produced by part hydrogenation of oils, which causes isomerization and relocation of some double bonds giving more solidity to the fat and increasing its trans fatty acids content.

Are there any foods that are high in trans fats?

Summary Popcorn is a healthy, high-fiber snack. However, some varieties of microwaveable popcorn hold trans fats. To avoid trans fats, refrain from store-bought popcorn made with partially hydrogenated vegetable oil — or make your own. 3. Certain Margarines and Vegetable Oils

Are there any trans fats in vegetable oils?

Some vegetable oils may contain trans fats, especially if the oils are hydrogenated. As hydrogenation solidifies oil, these partially hydrogenated oils were long used to make margarine. Therefore, most margarines on the market were high in trans fats. Fortunately, trans-fat-free margarine is increasingly available as these oils are phased out.

Why are hydrogenated oils used in food formulation?

Hydrogenated oils are popular for food formulation (Podmore, 2008) because they are versatile, oxidatively stable, and crystallize well in the desired beta-prime form (Floeter and Duijin, 2006). Animal fats, while essentially trans free, are higher in saturated acids and contain cholesterol which detracts from a health/nutrition perspective.
