the aim of the present study was to assess the effect of slaughter and carcass weight, age at slaughter and sex on the fatty acid profile of the greek boutsiko sheep breed. twenty lambs (ten females and ten males) were examined. the lambs were slaughtered at the age of 48 days. carcasses were chopped in nine specific cuts and a random sample of 100 g was taken from each cut, with a total of 180...

This review considers evidence for a protective effect of PUFA on chronic disease. Estimates of PUFA intakes in prospective cohort studies are usually based on FFQ or biomarkers of intake. Cohort studies suggest that both linoleic and linolenic acid intake are associated with a lower risk of CHD. The intake of fish, the major source of long-chain n-3 PUFA is associated with a lower risk of both...

In 1991, the Committee on Medical Aspects of Food Policy produced a report on the dietary reference values for food energy and nutrients for groups of people in the United Kingdom. The resulting recommendations, which included specific limits for intakes of total, saturated, trans- and cis-polyunsaturated fatty acids (PUFA) have remained a cornerstone of public health policy ever since, and sim...

The objective of this study was to evaluate the impact of diets enriched with plant oils or seeds, high in polyunsaturated fatty acids (PUFA), on the fatty acid profile of sheep intramuscular and subcutaneous adipose tissue (SAT). Sixty-six lambs were blocked according to initial body weight and randomly assigned to six concentrate-based rations containing 60 g fat/kg dry matter from different ...

Postprandial plasma insulin concentrations after a single high-fat meal may be modified by the presence of specific fatty acids although the effects of sequential meal ingestion are unknown. The aim of the present study was to examine the effects of altering the fatty acid composition in a single mixed fat-carbohydrate meal on glucose metabolism and insulin sensitivity of a second meal eaten 5 ...

The relevance of dietary fatty acids (FA) for blood lipids should be assessed in the context of substituting nutrients. Such evidence is lacking for adolescents. This study describes prospective associations of dietary FA with changes in serum lipids during adolescence, and considers the theoretical isocaloric replacements of saturated FA (SFA) with other FA or carbohydrates (CHO). Children fro...

Few EU countries meet targets for saturated fatty acid (SFA) intake. Dairy products usually represent the single largest source of SFA, yet evidence indicates that milk has cardioprotective properties. Options for replacing some of the SFA in milk fat with cis-monounsaturated fatty acids (MUFA) through alteration of the cow's diet are examined. Also, few people achieve minimum recommended intak...

The present study aimed to evaluate the lipid content and oxidation of fallow deer (FD), wild boar (WB), pig meat (PM) at −18 °C for a 360-day storage period. lowest fat was observed in thigh (TM) FD (2.53%; p ˂ 0.05). ratio polyunsaturated/saturated fatty acids (PUFA/SFA), n-6/n-3, hypocholesterolemic/hypercholesterolemic index (h/H), nutritional quality indexes were calculated. PUFA/SFA each ...

Adipose tissue (AT) fatty acid (FA) composition partly reflects habitual dietary intake. Circulating NEFA are mobilised from AT and might act as a minimally invasive surrogate marker of AT FA profile. Agreement between twenty-eight FA in AT and plasma NEFA was assessed using concordance coefficients in 204 male and female participants in a 12-month intervention using supplements to increase the...
