The increasing use of unconventional feedstuffs in chicken's diets results in the substitution of starch by lipids as the main dietary energy source. To evaluate the responses of genetically fat or lean chickens to these diets, males of two experimental lines divergently selected for abdominal fat content were fed isocaloric, isonitrogenous diets with either high lipid (80 g/kg), high fiber (64...

OBJECTIVE To determine whether a short set of questions about foods in the household can provide information about the fat-related dietary behaviour of individual household members in less-acculturated Chinese populations. DESIGN Cross-sectional survey. PARTICIPANTS The study population included 244 adult females of Chinese ethnicity in Seattle, WA, and Vancouver, BC, Canada. SETTING Bili...

Spillover of lipoprotein lipase-generated fatty acids from chylomicrons into the plasma free fatty acid (FFA) pool is an important source of FFA and reflects inefficiency in dietary fat storage. We measured spillover in 13 people with type 2 diabetes using infusions of a [(3)H]triolein-labeled lipid emulsion and [U-(13)C]oleate during continuous feeding, before and after weight loss. Body fat w...

OBJECTIVE This report examines how sources of fat and patterns of fat-related dietary habits differed between black, Hispanic and white women participating in a randomized trial of a low-fat diet intervention. DESIGN The intervention consisted of group sessions, which met weekly for 6 weeks, biweekly for 6 weeks and monthly for 9 months, and included didactic nutrition education and activitie...

BACKGROUND & OBJECTIVES Conjugated linoleic acid (CLA) reduces fat deposition in the body, but the mechanism of action is not clear. The present study was conducted to investigate the effects of CLA on body fat metabolism. Since milk fat is the best natural source of dietary CLA, intervention of non-fat milk constituents on CLA treatment was also investigated. METHODS Diets containing CLA (1%...

The drastic worldwide increase in obesity during the last decades is accompanied with several different health disorders. The underlying mechanisms for this escalation is not clear, but certain alterations in the dietary macronutrient composition are suggested to be of importance. In addition to an elevation in energy intake, these alterations include increased consumption of refined carbohydra...

Whereas dietary fibers are well recognized for nutritional management of human health issues, fiber is also known to be one of the dietary factors potentially affecting digestive use of dietary proteins. As a staple food, potato (Solanum tuberosum) may be a significant dietary fiber source. The objective of this study was to examine effects of dietary supplementation of six potato cultivar-geno...

Epidemiologic investigations have suggested an association of dietary fat intake with prostate cancer risk, especially risk of advanced prostate cancer. However, supporting evidence from animal studies is limited. Segments that would bridge animal and human studies on dietary fat and prostate cancer--which would determine the future directions of research--are missing. Such segments include 1) ...

this study was conducted to investigate the effects of l-carnitine and different levels of animal fat on performance, carcass characteristics and some blood parameters of broiler chickens. two hundred one-day old male broiler chicks were allotted to5 treatments in 4 replicates and 10 birds in each replicate. dietary treatments consisted of: 1) diet with 5% vegetable oil (t1), 2) diet with 5% ve...
