Fat digestion and metabolism differ widely between animal species. In ruminants, dietary fats are hydrogenated in the rumen before intestinal absorption so that absorbed fatty acids (FA) are more saturated than dietary FA. In non-ruminants, intestinal FA digestibility depends on the level of saturation of dietary FA. Fat supplementation of the diet of cows decreases milk protein and has a varia...

Recent meta-analyses have found no association between heart disease and dietary saturated fat; however, higher proportions of plasma saturated fatty acids (SFA) predict greater risk for developing type-2 diabetes and heart disease. These observations suggest a disconnect between dietary saturated fat and plasma SFA, but few controlled feeding studies have specifically examined how varying satu...

BACKGROUND Fatty acids play a vital role in glucose homeostasis; however, studies on habitual dietary fat intakes and gestational diabetes mellitus (GDM) risk are limited and provide conflicting findings. OBJECTIVE We determined whether the total amount and the type and source of prepregnancy dietary fats are related to risk of GDM. DESIGN A prospective study was conducted in 13,475 women w...

BACKGROUND It is unclear whether immediate dietary effects on blood glucose influence the risk of developing type 2 diabetes. OBJECTIVE The objective of this study was to examine whether the dietary glycemic index (GI) and glycemic load (GL) were associated with the risk of type 2 diabetes in older adults. DESIGN The Health, Aging, and Body Composition Study is a prospective cohort study of...

Data are limited on how dietary sources of energy and nutrient intakes differ among ethnic groups in the USA. The objective of the present study was to characterise dietary sources of energy, total fat, saturated fat, protein, dietary fibre and added sugar for five ethnic groups. A validated quantitative FFQ was used to collect dietary data from 186,916 men and women aged 45-75 years who were l...

OBJECTIVES To compare the diet quality and weight status of girls consuming diets meeting the recommendation of the American Academy of Pediatrics for dietary fat with those of girls consuming >30% of energy from fat and to examine relationships between girls' dietary fat intake, mothers' nutrient intakes, and mothers' child-feeding practices. DESIGN Participants were 192 white girls and thei...

Overweight and obesity are chronic diseases, which are increasingly affecting children and adolescents, and if not treated immediately then fat children from today will become patients from tomorrow. The objective of this study was to investigate whether dietary fat restriction normalizes body weight, impaired glucose tolerance and endothelium-dependent contractions induced by high dietary fat ...

OBJECTIVE To examine the associations between reported intakes of dietary fat and incident type 2 diabetes. RESEARCH DESIGN AND METHODS We studied the relation between dietary fatty acids and diabetes in a prospective cohort study of 35,988 older women who initially did not have diabetes. Diet was assessed with a food frequency questionnaire at baseline, and 1,890 incident cases of diabetes o...

background: high dietary fat consumption may alter oocyte development and embryonic development. this prospective study was conducted to determine the relation between dietary fat consumption level, its food sources and the assisted reproduction parameters. methods: a prospective study was conducted on 240 infertile women. in assisted reproduction treatment cycle, fat consumption and major food...

A study was undertaken with marketable size turbot to evaluate the effects of dietary fat levels on chemical composition, lipogenesis and flesh quality. Four experimental diets containing graded levels of fish oil in order to obtain 10%, 15%, 20% and 25% of crude fat were fed to triplicate Ž . groups of turbot initial body weight of 660 g for 12 weeks in full strength seawater at temperature of...
