Vaccenic acid is a naturally occurring trans fatty acid and an omega-7 fatty acid. It is the predominant kind of trans-fatty acid found in human milk, in the fat of ruminants, and in dairy products such as milk, butter, and yogurt. [1] [2] Trans fat in human milk may depend on trans fat content in food.
Studies show however that individual isomers have distinct health effects. [4] [5] Conjugated linoleic acid is both a trans fatty acid and a cis fatty acid. The cis bond causes a lower melting point and, ostensibly, also the observed beneficial health effects. Unlike other trans fatty acids, it may have beneficial effects on human health. [6]
Seafood chain Long John Silver's recently announced that its entire menu now has zero grams of trans fat due to a transition from partially hydrogenated cooking oils to 100 percent soybean oil in ...
High-fat dairy products such as butter contain about 4%. Margarines not reformulated to reduce trans fats may contain up to 15% trans fat by weight, [57] but some reformulated ones are less than 1% trans fat. Shortenings for deep-frying in restaurants can be used for longer than most conventional oils before becoming rancid.
Saturated and some trans fats are typically solid at room temperature (such as butter or lard), while unsaturated fats are typically liquids (such as olive oil or flaxseed oil). Trans fats are very rare in nature, and have been shown to be highly detrimental to human health, but have properties useful in the food processing industry, such as ...
Fred August Kummerow (October 4, 1914 – May 31, 2017) was a German-born American biochemist.A longtime professor of comparative biosciences at the University of Illinois at Urbana–Champaign, Kummerow was best known as an opponent of the use of artificial trans fats in processed foods, carrying out a 50-year campaign for a federal ban on the use of the substance in processed foods.

The products claim to have no partially hydrogenated vegetable oils added, no trans fat, [1] and to be comparable in quality to vegetable oil based products. [ citation needed ] The oils used in Smart Balance products contain low levels of naturally occurring trans fats, about 70 mcg of trans fat per serving.
