Summary
Nutrition and dietetics encompass the scientific study of nutrients in foods, their metabolism within the body and the application of this knowledge to promote health, prevent disease and manage clinical conditions. The field integrates biochemistry, physiology and behavioural science to understand how dietary patterns, food quality and nutrient interactions influence growth, energy balance, immune function and chronic‐disease risk across the life course. Dietetic practice applies evidence‐based guidelines to design individualised meal plans—ranging from therapeutic regimens for metabolic disorders to public health interventions such as food fortification and dietary policies. Emerging areas include precision nutrition, which tailors dietary advice using genetic, epigenetic and exposomal profiles, and sustainability‐focused diet modelling that aligns human health with environmental impact. By bridging fundamental research, technological innovation in food systems and personalised counselling, nutrition and dietetics aim to optimise nutrient adequacy, support functional well‐being and reduce the global burden of malnutrition and noncommunicable diseases.
Research from Nature Portfolio
Analyses of global food retail data from 2009 to 2023 reveal a rapid shift towards chain‐dominated brick‐and‐mortar and digital grocery sales, changes that correlate with rising obesity prevalence, particularly in lower‐income regions. These findings underscore the need for real‐time monitoring of retail environments to inform targeted interventions promoting healthier options. In complementary work, a major trial of a microbiome‐directed complementary food formulated with defined glycans demonstrated enhanced weight gain in malnourished children; metagenomic and gnotobiotic mouse studies identified Prevotella copri strains as key mediators of glycan metabolism and host energy regulation, paving the way for next‐generation therapeutic foods. A genotype‐stratified weight‐loss trial assessed “fat‐responder” and “carbohydrate‐responder” panels on high‐fat versus high‐carbohydrate diets, showing no significant benefit of matching diets to current genetic panels—highlighting the complexity of translating polygenic data into effective dietary prescriptions.

Technical terms
Microbiome-directed complementary food: A therapeutic formulation designed with specific glycans to selectively nourish beneficial gut microbes and restore healthy community structures, thereby improving host nutritional status.
Exposome: The cumulative measure of environmental, dietary, lifestyle and endogenous exposures across an individual’s lifespan that influences health and disease risk.
Functional unit: A reference measure (e.g., per 100 kcal or per unit of micronutrient) used in environmental and nutritional life-cycle assessments to standardise comparisons of foods.
Polygenic risk score (PRS): A composite metric derived from multiple genetic variants to estimate an individual’s inherited predisposition to traits such as dietary response or disease susceptibility.
Precision nutrition: The application of an individual’s genetic, metabolic and exposomal data to tailor dietary recommendations for optimal health outcomes.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
