The teenage years bring big changes in body, appetite, and habits — and nutrition plays a major role in growth, mood, concentration, and long-term health. Whether your teen is gaining or losing weight, or simply not eating well, supportive guidance makes a difference.

What teenagers need: enough energy and protein for growth, plenty of fruit and vegetables, whole grains for steady energy, calcium and vitamin D for developing bones, and iron (especially important for teenage girls).

Supportive strategies for parents:

• Keep nutritious food easy to grab at home; limit sugary drinks and ultra-processed snacks.
• Eat together when you can — family meals support better eating.
• Avoid framing food around weight or shame; focus on energy, health, and feeling good.
• Watch for warning signs of disordered eating, and seek help early if you’re concerned.

If your teenager has nutrition-related concerns or you’d like tailored guidance, a pediatric consultation can help.
