what is trans fat in foods.?

Answer 1

Trans fat is the common name for a type of unsaturated fat with trans isomer fatty acid(s). Trans fats may be monounsaturated or polyunsaturated.

A particular class of trans fats occurs, in small quantities, in meat and dairy products from ruminants. Most trans fats consumed today, however, are industrially created as a side effect of hydrogenation of plant oils — a process developed in the early 1900s and first commercialized as Crisco in 1911. The end effect of hydrogenation is to add hydrogen atoms to unsaturated fats, making them more saturated. These more saturated fats have a higher melting point and a reduced tendency for oxidation, resulting in a longer shelf-life. Chemically, trans fats are made of the same building blocks as non-trans fats, but have a different arrangement. In trans fatty acid molecules, the hydrogen atoms bonded to pair(s) of doubly bonded carbon atoms (characteristic of all unsaturated fats) are in the trans rather than the cis arrangement. This results in a straight, rather than kinked, shape for the carbon chain. The shapes of these trans molecules are similar to saturated fats, which are always straight chains. One result of a change in arrangement from cis to trans is a higher melting point.

Unlike other fats, trans fats are neither required nor beneficial for health.[1] Eating trans fats increases the risk of coronary heart disease.[2] For these reasons, health authorities worldwide recommend that consumption of trans fat be reduced to trace amounts. Trans fats from partially hydrogenated oils are generally considered to be more of a health risk than those occurring naturally.[3]

Trans fats are tightly regulated in some countries, must be disclosed on product labels in many others, and are the central issue in several ongoing lawsuits (particularly against fast food outlets). Many companies are voluntarily removing trans fats from their products, or establishing trans-free product lines.

I don't know if it's true or not, but I've heard that things like margarine is just a molecule away from plastic and/or Vaseline/petroleum jelly. How's that for good eats?
