Current Opinion in Gastroenterology, 2001
Many advances in the study of nutrient absorption have been made with the use of molecular and genetic techniques; however, standard in vivo studies have provided interesting and important new information. Omega-3 long-chain fatty acids have unexpected effects on lipoprotein formation and secretion in neonatal intestinal cells; this needs to be ...

Because it is ultimately dispersed back to space as heat, energy flows in only one direction through an ecosystem. In contrast, the materials from which living matter is fashioned are in constant circulation back and forth between plants and animals and the non-living environment.

Why are nutrients considered pollutants, since they are required for life? Input of excess nutrients such as nitrogen (N) and phosphorus (P) causes major problems in the aquatic environment.

Nutrient Cycles and Nutrient Limitations in the South [PDF]
, 1989 The impact of acidic deposition on forest soils depends largely on the nutrient cycles of the forest, and management treatments (such as fertilization) may also be important. As noted in chapter 2, if a forest utilizes the nitrate or sulfate from atmospheric deposition, the associated acidity is neutralized.

Nutrient efficiency along nutrient availability gradients
Oecologia, 1999The validity of nutrient use efficiency as a central concept in ecosystem ecology has recently been subject to challenge based upon arguments over autocorrelation of data, interpretation of graphical approaches, and appropriate statistical analyses. Much of the confusion on the measurement and interpretation of nutrient use efficiency results from the ...

Mitochondria in response to nutrients and nutrient-sensitive pathways
Mitochondrion, 2010Mitochondria are abundant cellular organelles, and are required for the generation of energy through oxidative catabolism. Equally important, mitochondria also provide substrates for de novo synthesis of fatty acids and multiple amino acids. Mitochondrial functions must therefore be tightly linked to cellular nutrient availability.

Nutrition Reviews, 2012
Nutrient intake recommendations, unlike hormone replacement standards, are based empirically, rather than physiologically, i.e., they lack an a priori normal referent. Randomized controlled trials do not provide the needed referent and are unlikely to distinguish between fully normal and various suboptimal nutritional states.
