Linoleic acid requirement of rats fed trans fatty acids.

The amount of linoleic acid required to prevent undesirable effects of C18 trans fatty acids was investigated. In a first experiment, six groups of rats were fed diets with a high content of trans fatty acids (20% of energy [en%]), and increasing amounts of linoleic acid (0.4 to 7.

[Nutritional aspects of hydrogenated soy oils and their isomeric unsaturated fatty acids].

The results of long-term feeding experiments with three species of animals which received considerable amounts of soyabean oil hydrogenated in different ways confirm the safety-in-use of this type of product. Just like saturated or cis monoenoic fatty acids, monoenoic and polyenoic fatty acids with the trans configuration always have to be supplemented with an adequate amount of cis-cis linoleic acid. The unfavourable effects observed in rabbits after prolonged feeding with one of the studied hydrogenated fats were to be expected in view of the marginal amounts of linoleic acid present in the diet they received.
