This case study examined the nutritional behavior and energy balance in an official finisher of a 24-hour ultracycling race. The food and beverages consumed by the cyclist were continuously weighed and recorded to estimate intake of energy, macronutrients, sodium, and caffeine. In addition, during the race, heart rate was continuously monitored. Energy expenditure was assessed using a heart rat...

BACKGROUND Evidence suggests a relation between short sleep duration and obesity. OBJECTIVE We assessed energy balance during periods of short and habitual sleep in normal-weight men and women. DESIGN Fifteen men and 15 women aged 30-49 y with a body mass index (in kg/m(2)) of 22-26, who regularly slept 7-9 h/night, were recruited to participate in this crossover inpatient study. All partic...

1-kestose is a trisaccharide and is one of the components of fructooligosaccharide (FOS). Although FOS is a typical non-digestible oligosaccharide with several beneficial health effects that have been clarified, the detailed properties of 1-kestose itself remain unknown. We first determined the digestibility of 1-kestose using rat and human small intestinal homogenates and the inhibition of 1-k...

This study was conducted to determine the chemical composition and metabolizable energy of poultry by-product meal (PBPM) from two slaughterhouses in Iran. Samples were analyzed for dry matter, crude protein, ash, ether extract and gross energy. The amounts of calcium, phosphorus, sodium, potassium, Magnesium, Iron, Manganese, copper and Zinc were determined. The apparent metabolizable energy (...

The objectives of this study were to determine the ileal digestible energy (IDE), ME, and ME(n) contents of corn distillers grains (CDG) for broiler chickens and to quantify these energy utilization responses to carbohydrase supplementation by the regression method. The CDG sample used in the current experiment contained (by analysis) 936 g/kg of DM, 4,894 kcal/kg of gross energy, 315.1 g/kg of...

OBJECTIVES The goal of this study was to investigate the nutrition adequacy and energy availability for physical activity in free-living, clinically stable patients with chronic heart failure (CHF). BACKGROUND Little information exists regarding the nutrition adequacy and alimentary habits of patients with clinically stable CHF. We hypothesized that CHF patients have an inadequate intake of c...

Temperature-dependent conformational changes of the principal apoprotein of human plasma high density lipoprotein (HDL), apoA-I, have been studied in the isolated apoprotein, in complexes of apoprotein with phospholipid, and in intact HDL. Differential scanning calorimetry shows that in solution apoA-I undergoes a reversible, two-state thermal denaturation (midpoint temperature 54 degrees). The...

This study was conducted to investigate the effects of corn addition to Italian ryegrass (IRG) (Lolium multi ̄orum Lam.) on rumen environment, nutrient digestibility, methane production and energy and nitrogen utilization by goats at two intake levels. Eight castrated Japanese goats were employed in two sequential digestion and metabolism trials. The goats were divided into two groups, offered t...
