About International Journal of Nutrition
Advancing Nutritional Science Through Rigorous Research and Open Access Publishing
Our Mission
The International Journal of Nutrition (IJN) is a peer-reviewed, open access scientific journal dedicated to advancing the understanding of nutrition's critical role in health maintenance, disease prevention, and therapeutic intervention. We publish high-quality research articles, comprehensive reviews, and impactful clinical studies that address the evolving landscape of nutritional science from molecular mechanisms to public health applications.
Nutrition is the cornerstone of human health, encompassing the study of how nutrients—including vitamins, minerals, carbohydrates, proteins, and fats—support physiological functions and influence disease outcomes. Beyond essential macronutrients and micronutrients, foods contain bioactive compounds such as phytochemicals, polyphenols, and antioxidants that exert profound health-promoting effects.
Optimal nutrition varies significantly across life stages, each presenting unique nutritional requirements and challenges:
- Prenatal & Maternal Nutrition: Critical for fetal development, birth outcomes, and long-term offspring health
- Infant & Childhood Nutrition: Foundation for growth, cognitive development, and metabolic programming
- Adolescent Nutrition: Supporting rapid growth, bone health, and establishing lifelong dietary patterns
- Adult Nutrition: Disease prevention, weight management, and performance optimization
- Geriatric Nutrition: Addressing malnutrition, sarcopenia, and age-related metabolic changes
Emerging research demonstrates the profound connection between nutrition and brain health. Dietary patterns influence neurotransmitter production, neuroplasticity, and inflammatory pathways that affect mood, cognition, and mental health disorders. Evidence supports nutritional interventions for depression, anxiety, cognitive decline, and neurodegenerative diseases.
IJN welcomes original research and comprehensive reviews addressing all aspects of nutritional science, including but not limited to:
Medical nutrition therapy, nutritional assessment, disease-specific dietary interventions
Nutrigenomics, nutrigenetics, metabolomics, and molecular mechanisms of nutrients
Population dietary patterns, nutrition policy, food security, dietary guidelines
Performance optimization, exercise metabolism, supplementation, body composition
Growth & development, childhood obesity, feeding practices, malnutrition
Diet-disease relationships, cohort studies, dietary assessment methods
Bioactive compounds, food processing, nutrient bioavailability, fortification
Energy balance, metabolic syndrome, weight management interventions
Metabolic pathways, nutrient-gene interactions, cellular mechanisms
Aging, sarcopenia, frailty, and nutritional interventions for the elderly
Diet-microbiota interactions, probiotics, prebiotics, metabolic health
Vegetarian diets, vegan nutrition, plant protein, sustainability
