Two studies were conducted to evaluate the effects of increasing dietary lysine and energy density on performance of Genetiporc nursery pigs. Experiment 1 was organized as a combination of two simultaneous experiments with one set of diets consisting of five treatments with increasing true ileal digestible (TID) lysine (0.99, 1.07, 1.14, 1.22, and 1.30%) and the second set of diets consisting o...

OBJECTIVE High consumption of energy-dense foods has been linked to high energy intakes and excess weight gain. This study tested the hypothesis that high energy density of the total diet is associated with lower diet costs. DESIGN Dietary intakes of 837 French adults, aged 18-76 years, were assessed using a dietary history method. Dietary energy density (MJ kg(-1)) was calculated by dividing...

BACKGROUND Gestational Diabetes Mellitus (GDM) increases risks for type 2 diabetes and weight management is recommended to reduce the risk. Conventional dietary recommendations (energy-restricted, low fat) have limited success in women with previous GDM. The effect of lowering Glycaemic Index (GI) in managing glycaemic variables and body weight in women post-GDM is unknown. OBJECTIVE To evalu...

Twelve groups of eight rats and two control groups of sixteen rats were given semisynthetic diets with 40% energy as fat for a period of 76 d. All diets contained a minimum of 3% energy as linoleic acid and comparable basal levels of D-alpha- and D-gamma-tocopherol. The diets varied in fat composition and in the content of DL-alpha-tocopheryl acetate. The diets high in polyunsaturated fatty aci...

although on the basis of geo-economic theories, study of energy-related issues is of strategic importance to all countries, energy resources are no more restricted to oil and gas reserves as was the case during the past century. of course, these resources are still key elements of global energy reserves. today, in addition to geo-politics and geo-economics, the concept of hydro-geopolitics puts...

to compare the nutritional value of rapeseed meal and cottonseed meal in holstein cows, feeding 20 lactating holstein cows each with an average weight of 580± 34 kg and 100± 10 days in milk were studied in a randomized complete block design. the experimental diets consisted of 4 levels of 0, 8, 14 and 25 percent rapeseed meal replaced with cottonseed meal and barley grain in the diets. diets we...

Calorie restriction (CR) via manipulating dietary carbohydrates has attracted increasing interest in the prevention and treatment of metabolic syndrome. There is little consensus about the extent of carbohydrate restriction to elicit optimal results in controlling metabolic parameters. Our study will identify a better carbohydrate-restricted diet using rat models. Rats were fed with one of the ...

Magnesium is an essential mineral that is required for optimal biological function including energy metabolism. Although national nutritional surveys indicate that usual magnesium intakes do not meet recommendations, particularly among older women, diet-induced magnesium depletion is considered rare among humans without concurrent illness. We examined the effects of dietary magnesium restrictio...

BACKGROUND Obesity and diabetes are frequently associated with nonalcoholic steatohepatitis (NASH), but studies have been hampered by the absence of a suitable experimental model. OBJECTIVE Our objective was to create a rat model of NASH. DESIGN Sprague-Dawley rats were fed a high-fat, liquid diet (71% of energy from fat, 11% from carbohydrates, 18% from protein) or the standard Lieber-DeCa...
