For more than 25 years, epidemiologic studies have reported on the relation of dietary fat to the risk of prostate cancer. Indeed, fat per se, or food sources of fat, has probably been the most studied of all dietary factors with regard to this cancer site. Despite this extensive investigative effort, the role of dietary fat in prostate cancer remains unclear. The hypothesis that dietary fat in...

The general public's view of macronutrients has undergone sweeping changes in recent years. Dietary fats are a key example. Since the anti-fat health education initiatives of the 1980s and early 1990s, certain dietary fats have been increasingly recognized as actually beneficial to health. Athletes, like the mainstream populace, are now getting the message that wise dietary fat (triacylglycerol...

A total of 600 1-d-old Hybro N broiler chicks were randomly distributed into 24 litter pens and fed from 21 to 52 d of age isocaloric and isonitrogenous diets containing 8% of three different fat sources (tallow, lard or sunflower oil). Dietary treatment produced a significant effect (P < 0.05) in fatty acid composition of the intramuscular neutral lipids among all dietary treatments and for al...

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 ...

This study investigated the effects of replacing soybean meal (SM) with canola meal (CM) and decreasing crude protein (‎CP) levels in CM based diets on performance of dairy cows when different sources of processed grains and CM were used. Canola meal was untreated or roasted at 130°C for 30 minutes and grains sources (corn and barley) were either ground or steamed-flaked. Eight Holstein cows (‎...

It has been shown that children with pancreatic fibrosis who have no pancreatic lipase at all may absorb a considerable proportion of dietary fat (Shohl, 1948; Andersen, 1945a and b; Ross, 1955). In addition it has been demonstrated by Andersen (1945a) that there may be a considerable amount of hydrolyzed fat in the stools of children with pancreatic fibrosis. These findings would indicate the ...

This experiment was conducted to determine the effect of different vegetable oil types on broiler energy expenditure, abdominal fat deposition and fatty acid profile of breast and thigh. A total number of 300 un-sexed day-old cobb 500 broiler chickens were used in a completely randomized design, consisted of five treatments (five different vegetable oil sources including soy, flaxseed, canola, ...

During the past several decades, reduction in fat intake has been the main focus of national dietary recommendations to decrease risk of coronary heart disease (CHD). Several lines of evidence. however, have indicated that types of fat have a more important role in determining risk of CHD than total amount of fat in the diet. Metabolic studies have long established that the type of fat, but not...

Background: The present study was conducted to investigate the effects of dietary fat sources on reproductive performance of mature rams. Materials and Methods: Twelve adult rams, with 32 months of age and a mean weight value of 67 kg, were divided into four dietary treatments using a completely randomized design. Dietary treatments included with the study were: 1. ration with 4% soybean oil (A...

BACKGROUND Consumption of healthy diets that contribute with adequate amounts of fat and fatty acids is needed for children. Among Guatemalan children, there is little information about fat intakes. Therefore, the present study sought to assess intakes of dietary fats and examine food sources of those fats in Guatemalan children. METHODS The study subjects consisted of a convenience sample of...
