Healthy Eating Week: The Intersection of Diet and Mental Wellbeing in Children cover image

Healthy Eating Week, led by the British Nutrition Foundation (BNF), is a key campaign promoting healthier eating for everyone, especially children. This event not only encourages balanced eating habits but also highlights the strong link between nutrition and mental health, particularly during childhood.

The correlation between diet and mental health has garnered substantial attention in recent years, with a growing body of research underscoring the critical impact of nutrition on psychological wellbeing. For children, whose brains and bodies are in a continuous state of growth and development, the role of a balanced diet cannot be overstated.


Nutritional Foundations for Children’s Mental Health

  1. Essential Nutrients: A child’s diet must encompass a broad spectrum of nutrients that are vital for cognitive function and emotional stability. Omega-3 fatty acids, found in oily fish, have been linked to reduced symptoms of depression and anxiety. Similarly, a diet rich in fruits, vegetables, whole grains, and lean proteins provides the necessary vitamins and minerals that support brain health. For instance, vitamins such as B6, B12, and folate are crucial for the production of neurotransmitters that regulate mood .
  2. Gut-Brain Axis: Emerging research has highlighted the significance of the gut-brain axis, indicating that a healthy gut microbiome can positively influence mental health. Diets high in fibre, probiotics, and prebiotics contribute to a healthy gut, which in turn can help mitigate mood disorders and enhance overall cognitive function .


Healthy Eating Week: Objectives and Impact

Healthy Eating Week aims to create awareness and encourage practical steps towards better dietary habits. The campaign is designed around five key themes:

  1. Eat more wholegrains: Encouraging the consumption of wholegrain foods to ensure an adequate intake of dietary fibre.
  2. Vary your veg: Promoting the inclusion of a wide variety of vegetables in daily meals.
  3. Drink plenty: Highlighting the importance of staying hydrated.
  4. Move more: Advocating for increased physical activity to complement a healthy diet.
  5. Be mind kind: Focusing on the psychological aspects of eating, such as mindful eating and the emotional impact of food choices .


Practical Steps for Parents and Educators

  1. Creating a Balanced Diet: Parents and educators can foster healthier eating habits by providing meals that incorporate the BNF’s themes. Practical steps include serving a variety of colourful vegetables, choosing wholegrain options, and ensuring regular water intake.
  2. Educating on Nutrition: Schools can integrate nutrition education into their curriculum, teaching children about the benefits of different food groups and how to make healthier choices.
  3. Encouraging Physical Activity: Alongside dietary advice, promoting regular physical activity is essential. Physical exercise is known to enhance mood and cognitive function, thereby supporting mental wellbeing.
  4. Mindful Eating Practices: Teaching children to practise mindful eating can help them develop a healthy relationship with food, recognising hunger and fullness cues and understanding the emotional triggers that influence eating habits.



Healthy Eating Week serves as an essential reminder of the profound impact that diet has on children’s mental health and wellbeing. By adopting a holistic approach that combines balanced nutrition, physical activity, and mindful eating practices, we can foster a generation of healthier, happier children. Ensuring that these practices are embedded in both home and educational environments will help nurture not only the physical health of children but also their mental and emotional resilience.
