Childhood is one of the most important stages of life for growth, learning and development. Every day, a child's body is building new brain connections, strengthening their immune system, developing healthy bones and muscles, and laying the foundations for lifelong health.

Yet today's children are growing up in a food environment unlike anything previous generations experienced.

Research suggests that by the age of seven, around 60% of the calories consumed by UK children come from ultra-processed foods. While scientists continue to investigate exactly how these foods affect health, there is growing concern about the impact of diets that are high in ultra-processed products and low in nutrient-rich whole foods.

It's Not About Blaming Parents

As a Diet and Lifestyle Advisor—and after spending six years working in schools—I know that today's parents are under enormous pressure.

Families are balancing work, school runs, clubs, homework, rising food costs and busy schedules. Convenience has become a necessity for many households, not a choice.

This isn't about guilt or striving for perfection.

It's about understanding that the food environment has changed dramatically, and learning how to make small, realistic improvements that support children's health without adding more stress to family life.

Children Need More Than Calories

When we think about feeding children, it's easy to focus on whether they've eaten "enough."

But growing children don't simply need calories—they need nutrients.

• Protein helps build muscles, tissues and important brain chemicals.
• Healthy fats support brain and nervous system development.
• Iron helps carry oxygen around the body and supports learning and concentration.
• Zinc contributes to growth and immunity.
• Omega-3 fats play an important role in healthy brain development.
• Fibre feeds the beneficial bacteria living in the gut.

Every meal is an opportunity to provide the building blocks that growing bodies need.

Why Stable Energy Matters

Many children begin the day with breakfasts that are high in refined carbohydrates and sugar.

While these foods provide quick energy, they can also lead to rapid rises and falls in blood sugar, leaving children feeling hungry, tired or struggling to concentrate before the school morning is over.

Including protein, healthy fats and fibre at breakfast can help provide steadier energy throughout the morning.

Simple examples include:

• Porridge topped with berries and seeds
• Eggs on wholegrain toast
• Natural Greek yoghurt with fruit and nuts
• Peanut or almond butter on wholegrain toast (where appropriate)

Small changes can make a noticeable difference.

The Gut-Brain Connection

One of the most exciting areas of nutrition research is the gut-brain axis—the constant communication between the digestive system and the brain.

Children's gut bacteria thrive on a varied diet that includes vegetables, fruit, beans, lentils, wholegrains, nuts and seeds.

These foods don't just support digestion. They also contribute to immune function and produce compounds that influence brain health and overall wellbeing.

Feeding the gut means supporting far more than the digestive system.

Food Is Just One Piece of the Puzzle

Children's behaviour, mood and ability to learn are influenced by many different factors.

Sleep, physical activity, relationships, emotional wellbeing, neurodiversity and home life all play hugely important roles.

Nutrition is not a magic solution—but it is one of the foundations that supports healthy growth and development.

When children consistently receive the nutrients their bodies need, they're giving themselves the best possible platform from which to learn, play and thrive.

Progress, Not Perfection

Healthy eating doesn't mean banning birthday cake or never relying on fish fingers after a busy day.

Real life doesn't work like that.

Instead, aim to make whole, minimally processed foods the foundation of family meals, while leaving room for flexibility and enjoyment.

• Every extra portion of vegetables counts.
• Every balanced breakfast counts.
• Every family meal shared around the table counts.
• Small choices, repeated consistently, often make the biggest difference over time.
