Food and Mood: How What You Eat Impacts Mental Health
Aug 24, 2026 Season 4 Episode 70
HSH Initiative

What you eat changes how you think and feel. Dietitian Claudia Jahjah joins Eddie Reaiche and psychologist Natalie Moujalli to talk about the mental health cost of ultra processed convenience food, why iron deficiency shows up as brain fog and irritability, and what is really happening when we reach for the chocolate at nine at night. Natalie shares her own struggle with food. Claudia never once shames her for it. You will learn what the gut brain axis does, and how to swap without punishing yourself.


About the Guest

Claudia Jahjah is a seasoned dietitian with over 20 years of experience. She works at Westmead and runs a private practice. Claudia specialises in a variety of areas, including diabetes care, weight management, cholesterol reduction, and sports nutrition for children. Her unexpected journey into private practice began with a serendipitous encounter following a job interview, where her faith played a significant role in guiding her career path. Claudia is passionate about using her expansive knowledge to educate and assist clients, making tangible impacts on their health and well-being.

Key Takeaways:

  • The Serendipitous Career Path: Claudia Jahjah’s career in private nutrition practice was initiated by a moment of reflection and faith, directing her away from optometry towards dietetics after a lapse in a job interview.
  • Nutrition & Mental Health: There is a significant connection between diet and mental health. Eating nutrient-dense foods can vastly influence emotional stability and overall mental wellness.
  • Mediterranean Diet Benefits: Recognised as highly beneficial for mental health, the Mediterranean diet's integrative approach—rich in healthy fats, vegetables, and whole grains—serves as a model for nutrition.
  • Challenges of Modern Eating Habits: Busy lifestyles lead to increased reliance on fast foods. Claudia highlights the importance of meal planning and simple, practical dietary adjustments to maintain health.
  • Emotional Eating Insight: Non-hungry eating and reliance on comfort foods can often indicate deeper emotional issues; swapping out snacks with healthier options can aid in breaking this cycle.

Notable Quotes:
