Overview

Nutrient deficiencies are states in which the intake or bioavailability of one or more essential nutrients is insufficient to meet physiological requirements, leading to impaired function and, if sustained, to characteristic clinical disorders. They arise from inadequate dietary intake, malabsorption, increased requirement or loss, and interactions among nutrients, and may involve macronutrients, with protein-energy malnutrition, or micronutrients, with the classic deficiency syndromes of vitamins and minerals. Micronutrient deficiencies, sometimes termed hidden hunger, can impair immune function, growth, cognition, and reproductive and metabolic health even in the absence of overt undernutrition, and they are shaped by socioeconomic conditions, food systems, and disease. Peer-reviewed research relevant to this area examines childhood micronutrient deficiency in relation to household economic status, the nutritional consequences of obesity and of bariatric surgery including thiamine deficiency and Wernicke encephalopathy, the impact of intestinal helminth infection on malnutrition and haematological indices, the diet and nutritional status of older adults, and the food-system determinants of deficiency including agricultural productivity and food security. Studies employ national surveys, clinical and observational research, and review across diverse settings. This work connects dietary inadequacy and its causes to clinical and population outcomes. The journal publishes peer-reviewed research in nutrition addressing nutrient deficiencies, nutritional status, and their determinants.
