Rats and mice occupy a special niche as animal models for two reasons; first, they share with humans a love of the same types of food, and second, they are the target of a number of well-developed genetic tools.
Numerous examples are cited where animal models have been used to solve nutrient 3 nutrient interactions, to evaluate bioavailability of nutrients and nutrient precursors, and to test for nutrient tolerances and toxicities.
Popular Animal Models for Nutrition and Genetics Research. Given the complexity of human behavior and the complexity of the human genome, the study of animals provides a useful option to learn about genetic influences on food selection.
1 wrz 2011 · Nutrigenomics approach is carefully selecting nutrients for finetuning genes and DNA presents in every cell and every tissue of an animal.
The review that follows focuses on the contributions of experimental animal models to what is known today about nutrient-nutrient interactions, bioavailability of nutrients and nutrient precursors, and tolerance levels for excessive intakes of nutrients.
Epigenetics is a biological phenomenon that involves the regulation of gene expression independent of the DNA base sequence. The field of nutritional epigenetics is further elucidating the nature of nutrient-gene and, more broadly, diet-gene interactions, thus providing support for the role of nutrition in acquiring new phenotypes.
1 lut 2008 · Current knowledge in nutrition is based largely on the use of appropriate animal models together with defined diets to solve nutrient x nutrient interactions, to evaluate bioavailability of nutrients and nutrient precursors, and to test for nutrient tolerances and toxicities.
