With the advent of present-day tools and techniques of analysis, it is possible and practical to measure accurately the essential trace element content of human foods. Although this is a major step forward in assessing nutrient needs and status, an important unknown remains. To meet nutritional requirements it is important to know not only the quantity consumed but the proportion of that consum...

Changes in nutrient bioavailability due to increased loading of dissolved organic matter (DOM) may impact boreal freshwaters. Yet, the relative carbon (C), nitrogen (N), and phosphorus (P) associated with terrestrial DOM remains poorly understood. We applied short-term bioassays natural bacterial inocula determine seasonal variation bioavailable pools from four headwater streams northern Sweden...

Background: Preventing the development of iron deficiency anemia during infancy requires the appropriate complementary foods with high energy, nutrient density, and adequate iron content, as well as high nutrient bioavailability. We aimed to evaluate iron intake, bioavailability, and absorption from foods, in healthy infants and toddlers at a Well Child Clinic. Methods: This observational, cros...

Several experiments were conducted to evaluate the variation in nutrient content and digestibility among different commercial samples of DDGS, the effects of different processing methods and feed additives on the bioavailability of P in DDGS and the effect of new processing technologies on the nutritional value of DDGS for poultry. The nutrient composition varied substantially among DDGS sample...

By identifying the relationship between calcium location in the plant cell and nutrient bioavailability, the plant characteristics leading to maximal calcium absorption by humans can be identified. Knowledge of plant cellular and molecular targets controlling calcium location in plants is emerging. These insights should allow for better strategies for increasing the nutritional content of foods...

BACKGROUND Codex documents may be used as educational and consensus materials for member governments. Also, the WTO SPS Agreement recognizes Codex as the presumptive international authority on food issues. Nutrient bioavailability is a critical factor in determining the ability of nutrients to provide beneficial effects. Bioavailability also influences the quantitative dietary requirements that...

Thin porridge from cereals and starchy tubers is a common complementary food in Sub Saharan Africa. It may be high in antinutrients, low in energy, and nutrient density hence inadequate in providing infants' high energy and nutrients requirements per unit body weight. Consequently, undernourishment levels among children under 5 years are high. Therefore, there is need to avail nutrient-dense co...
