A stronger relationship was apparent with an index of nutrient loading that combined residence time and nutrient concentration as the predictor (R2 = 0.289, p = 0.026).
Preliminary DMI, an index of nutrient demand, was determined during the last 4 d of the preliminary period when cows were fed a common diet and used as a covariate.
Effects of forage family on dry matter intake (DMI), milk production, ruminal pool sizes, digestion and passage kinetics, and chewing activity and the relationship of these effects with preliminary DMI (pDMI), an index of nutrient demand, were evaluated using 13 ruminally and duodenally cannulated Holstein cows in a crossover design with a 14-d preliminary period and two 18-d treatment periods.
What might be a useful index of nutrient exposure may not necessarily reflect nutrient status, which, in turn, may not necessarily reflect the impact or function of that nutrient.
Tree islands efficiently utilized both phosphorus and nitrogen, but indices of nutrient-use efficiency indicated stronger P than N limitation.
Nutritional biomarkers biochemical, functional, or clinical indices of nutrient intake, status, or functional effects—are needed to support evidence-based clinical guidance and effective health programs and policies related to food, nutrition, and health.
We examined the possible associations between breast cancer and various indices of nutrient and food intake in two Chinese populations who are at relatively low risk for breast cancer (one-fifth the rate in US white women).
To describe changes in breakfast and cereal consumption of girls between ages 9 and 19 years, and to examine the association of breakfast and cereal intake with body mass index (BMI) and consumption of nutrients.
Appendix 1 lists candidate tools, and we have classified them in three categories as a function of their determination mode, based on a now classical review (Kant 1996): a) indices based on intakes of nutrients (or at least of certain nutrients); b) indices based on the consumption of foods or of groups of foods; and c) indices that combine both approaches resulting in dietary patterns.
After adjustment for body mass index, higher intake of nutrient dense food was associated with a higher BMD among men ages 25-49.
