The effect of consuming different amounts of whey protein on appetite and energy intake was investigated in two separate studies using randomised, crossover designs. Healthy-weight men and women (range: BMI 19·0-25·0 kg/m², age 19·4-40·4 years) consumed one of four 400 ml liquid preloads, followed by an ad libitum test meal 90 min later. In study 1, preloads were 1675 kJ with 12·5, 25 or 50 % o...

Hypokalemia can result from an absence of cellular redistribution accompanied by low serum potassium levels, which can be secondary to inadequate dietary intake, external losses (for example, through the gut or skin), or renal losses. However, low serum potassium secondary to low potassium ingestion usually occurs after an extended period of low oral potassium intake. Also, increased renal pota...

The objective of this study was to evaluate the effect of three levels of supplement on forage intake and animal performance of early weaned calves grazing rye-ryegrass pastures from January to May. Treatments were three levels of concentrate (1, 1.5, and 2% of body weight [BW]), and animals were 90-d-old Angus-crossbred early weaned calves. Calf ADG increased from 1.6 to 1.9 lb/d as supplement...

The prevalence of overweight and obesity is increasing worldwide, affecting approximately 15% of adolescents in Venezuela, 17% in United States, and more than 30% in Mexico and Puerto Rico. Recent studies have shown that dietary calcium and dairy intake are associated with body fat. These studies show that a high calcium intake results in low body mass index (BMI). Therefore, the objective of t...

BACKGROUND There is growing evidence that quality, rather that quantity of fat is the determinant of cardiovascular risk. The objective of the study is to describe quantitatively the intake and adequacy of fatty acid classes among the Mexican population aged 5-90 years from a probabilistic survey. METHODS Dietary intake of individual and classes of fatty acids was computed from the dataset of...
