Nutritional deficiencies are conditions resulting from inadequate intake, absorption, or utilization of nutrients required for normal physiological function, spanning both macronutrient deficits, such as protein-energy undernutrition, and micronutrient shortfalls in vitamins and minerals. They manifest across a spectrum from subclinical biochemical depletion to overt clinical syndromes, including anemia, osteopenia, impaired immunity, growth and developmental delay in children, and specific deficiency diseases tied to individual nutrients. Etiologies include insufficient or poorly diversified diets, food insecurity, increased physiological demand during pregnancy, lactation, and childhood, malabsorptive disorders, restrictive eating, and the metabolic consequences of gastrointestinal and bariatric surgery. Diagnosis integrates dietary assessment, anthropometry, and biochemical markers, while management combines correction of intake, supplementation, and treatment of underlying causes. The subject matter examined in this area includes nutritional deficiencies in pregnancy after surgery for obesity, serum vitamin D status in vulnerable children, feeding problems and elemental-diet interventions in children with autism spectrum disorders, body composition and nutritional status in older adults, dietary diversity and nutritional status assessment in women and children, and the role of functional foods and nutraceuticals. The journal publishes peer-reviewed research on the causes, assessment, and correction of nutritional deficiencies across populations.
