WHO’s 2023 complementary-feeding guideline recommends a diverse diet for infants and young children aged 6–23 months because different foods contribute different nutrients and food experiences.

How to read this guidance

Population nutrition guidance explains patterns and prevention; it does not establish an individual deficiency, excess or feeding prescription. Growth history, dietary pattern, illness, absorption, laboratory findings and the child’s developmental stage all influence interpretation.

The sections below retain the factual scope of the linked source. They add practical questions and safety-netting without claiming that a symptom, measurement or exposure proves a diagnosis in one child.

What does dietary diversity mean in complementary feeding?

WHO’s 2023 guideline says infants and young children aged 6–23 months should consume a diverse diet. The guideline explains that a variety of foods helps meet nutritional needs and exposes young children to different tastes and textures.

Which food groups does WHO highlight?

WHO’s dietary-diversity recommendation specifically highlights animal-source foods such as meat, fish or eggs, fruits and vegetables, and pulses, nuts and seeds. The guideline also discusses grains, roots, tubers and dairy within the wider set of food groups used to describe dietary diversity.

Why can one staple food group be insufficient?

WHO explains that diets dominated by starchy staples may not provide the same range or quality of nutrients as a more diverse diet. The guideline notes that different food groups contribute different nutrients and that dietary diversity helps reduce the risk of nutrient deficiencies.

What does WHO say about fruits and vegetables?

WHO’s guideline recommends daily consumption of fruits and vegetables for children aged 6–23 months as part of dietary diversity. This is a global population-level recommendation, not a judgment about the intake of an individual child.

How does dietary diversity relate to complementary feeding overall?

Complementary feeding is the period when foods are provided in addition to milk because milk alone is no longer adequate to meet all nutritional requirements. WHO describes 6–23 months as a period in which children learn to accept healthy foods and beverages while growth and nutrient needs are substantial.

This page does not assess nutrition. Questions about an individual child’s growth, feeding difficulty, allergy, swallowing, nutrient deficiency or special dietary needs require qualified professional assessment.

Using dietary diversity as a pattern, not a score for one meal

A varied complementary diet is built across repeated meals and days. One meal does not have to contain every food group, and a child’s intake can change with appetite, illness and opportunity. A short food record can show the overall pattern more clearly than memory. Record the foods offered, what was accepted, the texture and any difficulty chewing, swallowing or staying comfortable during the meal.

The WHO recommendation describes food groups at population level. It does not set an individual portion, diagnose a deficiency or prescribe a menu for a child with allergy, growth concern or a medical feeding problem. Those decisions need the child’s growth history, health and feeding skills.

Building variety practically

  • continue the child’s usual milk feeding while offering age-appropriate complementary foods
  • offer different food groups across the day and week rather than relying mainly on a starchy staple
  • adapt texture and size to the child’s developmental ability and safe eating skills
  • repeat exposure calmly when a safe food is initially refused

Variety can come from ordinary family foods when they are prepared in a form suitable for the child. Families can use foods that are locally available, affordable and culturally acceptable. Avoid turning the recommendation into pressure to buy special products. Fortified foods or supplements may have a role in recognised programmes or an individual clinical plan, but more is not automatically better.

Food groups and meal planning

WHO highlights animal-source foods, fruits and vegetables, and pulses, nuts and seeds within dietary diversity, alongside the wider food-group framework described in the source. When planning, think about which groups have appeared recently and which can be added safely. Nuts and other foods must be offered in a texture and form that does not create a choking hazard.

Ask what could safely add another food group, taste or texture to foods the child already accepts. Aim for a sustainable household pattern.

Observe feeding as well as food choice

Notice whether the child can sit and eat safely, move food in the mouth, swallow comfortably and signal hunger or fullness. Also note repeated coughing or choking, prolonged meals, pain, vomiting, diarrhoea, constipation, rash or distress linked with eating. These observations can be more useful to a clinician than a list of disliked foods alone.

Growth should be interpreted from repeated, accurate measurements rather than one number. If there is concern about growth, nutrient intake or feeding skill, bring the food record and any product or supplement labels to a qualified professional.

Responsive mealtimes

Offer food patiently and allow the child to decide whether and how much to eat from what is safely provided. Avoid force, threats or using food as punishment. Keep distractions manageable and allow enough time without making meals indefinitely long. A consistent routine can make it easier to see whether appetite and participation are changing.

Food refusal is common, but persistent restriction, distress or inability to manage appropriate textures needs assessment. Advice may differ when a child was born preterm or has allergy, swallowing difficulty, disability, chronic illness or a prescribed therapeutic diet.

When to seek urgent or prompt help

  • the child cannot feed or drink, repeatedly chokes or has breathing difficulty
  • there are signs of severe dehydration, marked weakness or reduced alertness
  • weight is falling rapidly, severe wasting is visible or swelling develops
  • a food reaction includes breathing difficulty, facial swelling or collapse

Use emergency services for severe breathing difficulty, collapse or another rapidly worsening reaction. Arrange timely review for persistent feeding difficulty, poor growth, suspected allergy or a diet that has become very narrow. Do not remove major food groups or start concentrated supplements without appropriate advice.

Questions to take to a nutrition or healthcare review

Ask whether growth has been measured and interpreted correctly, which part of the food record needs attention, whether feeding skills should be assessed, and what realistic change to try first. Confirm how progress will be followed and what should trigger earlier reassessment.

Limits and source boundaries

Read the publication date and scope of the source. A global fact sheet may describe burden and prevention without providing a local treatment pathway; a surveillance or screening page may describe population practice without estimating one child’s risk.

Recommendations, schedules and available services differ by country and can change. Use the official source for its stated evidence and a qualified professional for decisions about the individual child.
