Objective: In the first days of life, breast-fed infants consume minimal amounts of milk; this may be explained by substrate limitation (limited milk output) and/or by self-limitation (through low appetite and/or suck-swallow competency). The spontaneous milk intake of unrestricted formula-fed infants has not been studied to date. We compared the spontaneous formula intake of unrestricted formula-fed infants to that of breast-fed infants over the first 48 hours of life. We hypothesized that 1) spontaneous formula intake of unrestricted infants is much higher than that of breast-fed infants and 2) spontaneous formula intake correlates positively with gestational age or birthweight.

High-Energy Diets, Fatty Acids and Endothelial Cell Function: Implications for Atherosclerosis

Diets high in fat and/or calories can lead to hypertriglyceridemia and postprandial lipemia and thus are considered a risk factor for the development of atherosclerosis. Plasma chylomicron levels are elevated in humans after consuming a high-fat meal, and hepatic synthesis of VLDL is increased when caloric intake is in excess of body needs. Continue reading →

Calcium Requirements during Adolescence to Maximize Bone Health

The calcium requirements of boys and girls during adolescence have largely been based on balance studies, including more recently the use of stable nuclides. Bone measurements by dual energy X-ray absorptiometry (DXA) and similar instruments have provided an end-point by which to assess skeletal development, either of the entire skeleton or of specific bones, in relation to the consumption of calcium and other nutrients and to physical activity.
