Balanced nutrition & growth
Adequate energy, protein, calcium and iron underpin a healthy height-weight curve and bone development.
Nutrition & growth
Read nutrition as part of growth, not on its own.
Nutrition directly affects the height-weight curve, bone development, athletic performance and mood. Child Growth reads nutrition together with growth tracking and digital-health screening; the goal is not a strict diet but a measurable, actionable family plan.

Nutrition domains
6This guide treats nutrition not as a single meal but as interconnected domains that affect growth.
Child-athlete nutrition
Nutrition that supports training, recovery and growth together; mindful of RED-S risk.
Obesity & BMI interpretation
Reading BMI percentile by age; not a single measure but the trend and lifestyle matter.
Micronutrients
Micronutrient gaps such as vitamin D and iron can affect growth and development.
Eating behaviour
Spotting picky eating, emotional eating and eating-disorder signals in adolescents early.
Clinical causes
Some conditions such as celiac disease can cause short stature; see a clinician for persistent issues.

How nutrition becomes product
Child Growth offers nutrition not only as content but as a measurable screen:
- Family screen: scores nutrition, sleep, screen, posture and psychosocial signals.
- Results are read together with the child’s growth percentiles.
- A nutrition summary is added to the PDF Child Growth Passport.
- For risky signals, clinician/dietitian referral is recommended.

Frequently asked questions
How does nutrition affect height?
Adequate energy, protein, calcium and vitamin D are needed for bone development and growth. Chronic shortfall or malabsorption (e.g. celiac) can contribute to short stature.
Is my child overweight? How is BMI interpreted?
In children, BMI is assessed by age- and sex-specific percentiles, not fixed adult thresholds. The trend and lifestyle matter more than a single measurement.
Is a child athlete’s nutrition different?
Yes. Because growth continues alongside training and recovery, energy and nutrient needs are higher. Inadequate intake can harm performance and growth (RED-S).
Does this page provide a diet prescription?
No. The content is educational and does not replace an individual diet plan. For a personalized plan, see a pediatrician and dietitian.
