RESUMEN
Los niños con cáncer se ven muy comprometidos en su alimentación en cuanto al consumo de proteínas y calorías. Las proteínas deben ser consumidas en cantidades suficientes de acuerdo a lo recomendado por la nutricionista infantil en su plan de alimentación. Las necesidades calóricas del niño con cáncer dependen de la edad, el peso, el estado nutricional, la actividad, el tipo de cáncer, las complicaciones y el estado del niño, entre otros, por lo que la nutricionista infantil junto con el pediatra, indicarán cómo ofrecer estas calorías al niño.
Children with cancer are very committed to their food in the consumption of protein and calories. Protein should be eaten in sufficient quantities in accordance with the recommendations of child nutrition in your food plan. Caloric needs of children with cáncer depends on age, weight, utritional status, type of cancer, complications and the child's condition, amongothers, so the child nutritionist with the pediatrician,tell you how to deliver these calories a child.

Amino acids are building blocks of proteins and key regulators of nutrient metabolism in cells. However, excessive intake of amino acids can be toxic to the body. Therefore, it is important to precisely determine amino acid requirements by organisms. To date, none of the methods is completely satisfactory to generate comprehensive data on amino acid requirements of animals or humans. Because of many influencing factors, amino acid requirements remain a complex and controversial issue in nutrition that warrants further investigations. Benefiting from the rapid advances in the emerging omics technologies and bioinformatics, biomarker discovery shows great potential in obtaining in-depth understanding of regulatory networks in protein metabolism. This review summarizes the current approaches to assess amino acid requirements of animals and humans, as well as the recent development of biomarkers as potentially functional parameters for recommending requirements of individual amino acids in health and disease. Identification of biomarkers in plasma or serum, which is a noninvasive approach, holds great promise in rapidly advancing the field of protein nutrition.

In healthy adult humans, eight amino acids (isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine) were shown classically by nitrogen balance studies to be indispensable. Subsequent studies classifying histidine as indispensable are reviewed in this article. We also review the evidence that in certain nutritional or disease states or in certain stages of development otherwise dispensable amino acids may become indispensable. Arginine, citrulline, ornithine, cysteine, and tyrosine thus may be considered as acquired indispensable amino acids. Evidence for the indispensability of taurine is also considered. We propose a classification of the indispensability of amino acids based on clinical and therapeutic considerations.
