<i>Trans</i> fatty acid isomers from hydrogenated fats: The controversy about health implications

Hydrogenated oils and polyunsaturated fatty-acid isomers in nutrition.

Human tissue lipids: occurrence of fatty acid isomers from dietary hydrogenated oils.

Hydrogenation of vegetable oils produces fatty acids with unusual structures having trans double bonds and double bonds in new positions of the acyl chain. This study was designed to determine which of these fatty acid isomers are incorporated or accumulated in humans during long-term dietary consumption of hydrogenated fats. The double bond position and configuration of the octadecenoate fract...

Fats and fatty acid requirements for adults.

Overweight and Obesity In most countries, the prevalence of obesity and overweight have increased severely [WHO, 2000]. Some prospective studies have demonstrated that foods high in fat and energy are associated with weight gain [Klesges et al., 1992; Schulz et al., 2002; Newby et al., 2003]. On the other hand, other prospective studies have yielded conflicting results on this topic [Colditz et...

The omega-6/omega-3 fatty acid ratio: health implications

The Center for Genetics, Nutrition and Health, 2001 S Street, NW, Suite 530, Washington DC 20009 USA Abstract: Today, Western diets are characterized by a higher omega-6 and a lower omega-3 fatty acid intake, whereas during the Paleolithic period when human’s genetic profile was established, there was a balance between omega-6 and omega-3 fatty acids. Their balance is an...
