The contents of trans-fatty acid (TFA) isomers of human substernal adipose tissue and plasma lipids (cholesterol esters, triacylglycerols, phospholipids), obtained from patients with angiographically documented coronary heart disease (CHD group; n = 24) and from controls (excluded CHD; n = 25), were determined by capillary gas chromatography. No significant difference (P <0.05) could be observed between cases (2.59 +/- 33%) and controls (2.79 +/- 0.76%) with regard to adipose tissue total TFA contents (expressed as proportion of all identified fatty acid methyl esters). The total adipose tissue TFA content reflected the dietary TFA intake, which was estimated by dietary questionnaires. Both groups showed significant differences in several isomeric plasma lipid TFA. Cases generally had a tendency to lower individual TFA contents.

Out-of-home meals are characterized by poor nutritional quality, and their intake has been linked to adverse health outcomes. Therefore, national and local government initiatives have been implemented in the UK to promote healthier out-of-home meals. However, there is limited evidence of their effectiveness.

Aims/hypothesis: Existing evidence on the relationship between intake of monounsaturated fatty acids (MUFAs) and type 2 diabetes is conflicting. Few studies have examined whether MUFAs from plant or animal sources (MUFA-Ps and MUFA-As, respectively) exhibit differential associations with type 2 diabetes. We examined associations of intakes of total MUFAs, MUFA-Ps and MUFA-As with type 2 diabetes risk.

This study aimed to examine the effects of supplementing a basal diet with resveratrol and black soldier fly () larvae meal on Manchurian Golden quail egg production and quality as well as consumer attitudes towards the quail eggs and their acceptability. Quail were allotted three treatments for a laying period of 3 months. The dietary treatment groups were those of a basal diet, a basal diet with 250 mg/kg resveratrol pliusACE, and a diet supplemented with 10% black soldier fly larvae meal (BSF).

This review provides an overview of the main vegetable oils of different botanical origin and composition that can be used for frying worldwide (olive and extra-virgin olive oil, high-oleic sunflower oil, rapeseed oil, peanut oil, rice bran oil, sunflower oil, corn oil, soybean oil, cottonseed oil, palm oil, palm kernel oil and coconut oil) and their degradation during this process. It is well known that during this culinary technique, oil's major and minor components degrade throughout different reactions, mainly thermoxidation, polymerization and, to a lesser extent, hydrolysis. If severe high temperatures are employed, isomerization to fatty acyl chains and cyclization are also possible.

This study aims to comparatively analyze butter, ghee, and margarine fatty acid profiles and their implications for healthier fat and oil group choices. In this cross-sectional study, 60 samples from best-selling brands of butter, ghee, and margarine were randomly selected from five food chain stores in Tehran, Iran. Then, all the samples were coded, packed in cool conditions, and sent to the laboratory to determine the fatty acid profiles by using gas chromatography (GC).
