Trans fat is a type of unsaturated fat that occurs in foods. [1] [2] Small amounts of trans fats occur naturally, but large amounts are found in some processed foods made with partially hydrogenated oils.
Cis unsaturated fatty acids, however, increase cellular membrane fluidity, whereas trans unsaturated fatty acids do not. trans A trans configuration, by contrast, means that the adjacent two hydrogen atoms lie on opposite sides of the chain. As a result, they do not cause the chain to bend much, and their shape is similar to straight saturated ...
The processing of fats by hydrogenation can convert some unsaturated fats into trans fat]]s. The presence of trans fats in various processed foods has received much attention. Margarine, a common product that can contain trans fats Cover of original Crisco cookbook, 1912. Crisco was made by hydrogenating cottonseed oil.
A saturated fat is a type of fat in which the fatty acid chains have all single bonds between the carbon atoms. A fat known as a glyceride is made of two kinds of smaller molecules: a short glycerol backbone and fatty acids that each contain a long linear or branched chain of carbon (C) atoms.
Meat products contain both saturated and unsaturated fats. Although unsaturated fats are conventionally regarded as 'healthier' than saturated fats, [6] the United States Food and Drug Administration (FDA) recommendation stated that the amount of unsaturated fat consumed should not exceed 30% of one's daily caloric intake. [7] Most foods ...
Aim to avoid saturated and trans fats. Foods high in saturated fats include red meat, butter, full-fat dairy products, baked goods, and palm and coconut oil. Trans fats are typically found in ...
Limit your intake of sugar and foods high in saturated or trans fats, such as fried foods, processed meats and baked goods. Especially try to cut out sugary drinks such as sodas, which have been ...
The desirable (left) and undesirable pathways for partial hydrogenation of an unsaturated fat. Elaidic acid is a trans fat with negative health effects. Full hydrogenation results in the conversion of all of the unsaturated fats into saturated fats by transforming all of the double bonds in the fat into single bonds.
