BACKGROUND Current dietary guidelines recommend that dietary fat should comprise 20-35% percent of total energy intake, with less than 10% of energy from saturated fat. However, many Americans exceed these goals and data suggest that African Americans tend to consume a higher percentage of energy from dietary fat than Whites. Because diets low in dietary fat, particularly saturated fat, are ass...

Studies were carried out to determine the independent and interactive effects of dietary fat and cholesterol on the regulation of hepatic apoB/E receptor expression and its relationship to hepatic cholesterol concentrations and low density lipoprotein (LDL) particle characteristics. Guinea pigs were fed 15% (w/w) fat diets (lard, olive oil, or corn oil) with cholesterol levels corresponding to ...

An experiment was conducted to study the interrelationships between dietary fat and protein levels in the regulation of lipid metabolism in the broiler chicken. Birds were fed diets containing 300, 600, or 1,200 kcal ME from fat (corn oil) with either 124 or 190 g CP/kg. Two additional experimental diets contained 234 or 285 g CP and 300 kcal ME from fat. Regardless of fat level, birds fed the ...

BACKGROUND Large cohort studies have reported no relationship between dietary fat and nonmelanoma skin cancer (NMSC), although a low-fat diet intervention reduced NMSC risk in a small clinical trial. In animal studies, skin tumor development has been reduced by low-fat diet. We evaluated the effect of a low-fat dietary pattern on NMSC and melanoma in the Women's Health Initiative Dietary Modifi...

Isocaloric substitution of polyunsaturated fat for saturated fat reduces concentrations of total plasma cholesterol and high density lipoproteins (HDL) in nonhuman primates. The biochemical mechanisms through which polyunsaturated fat lowers plasma HDL concentrations are not well understood but must involve changes in HDL production or HDL clearance from plasma, or both. To determine whether di...

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...

Background: Studies have shown that zinc and selenium deficiency is common in nonalcoholic fatty liver disease (NAFLD). However, the effects of zinc and selenium co-supplementation before and/or after disease progression on NAFLD are not clear enough. The aim of this study was to compare the effects of zinc and selenium co-supplementation before and/or after disease progression on NAFLD prognos...
