How does nutrition impact ADHD symptoms in children? And what action can we, as parents, take to better support our children and their diet?

In this episode of  the All Aboard ADHD podcast, Claire is joined by expert guest Lucinda Miller - family naturopath, functional medicine practitioner, author, coach and mentor for kids with ADHD and autism. She and Claire discuss how the food can affect the mood, behaviour and concentration of children with ADHD and other neurodevelopmental conditions. This episode offers judgement-free insight and practical, achievable strategies for parents facing the very real food challenges of their neurodivergent children.

Lucinda begins by sharing her approach to nutrition - which you can read more about in her new book Brain Brilliance - along with her own experience with ADHD and how food affects her day-to-day life. She describes the importance of zinc and iron in brain function, mood, and behavior, and how deficiencies can affect children with ADHD, for example expressing their mood and behaviour through food choices. We learn the crucial role zinc plays in a wide range of areas, from supporting the immune system and digestive health, to taste and smell, which can affect a child’s willingness to try new foods. Lucinda goes on to explain the role of dopamine and tyrosine in ADHD and how iron deficiencies can impair dopamine production - a crucial neurotransmitter for anyone with ADHD.

Claire and Lucinda also dive into the impact of nutritional deficiencies on ADHD and gut health in neurodivergent children. Lucinda talks through the daily nutritional needs for iron and zinc (especially for teenagers and children going through growth spurts), shares insight into the high prevalence of gut issues in children with autism, and how this can affect both nutrient absorption and brain function. She explains how ultra-processed foods are highly addictive and can exacerbate ADHD symptoms and suggests some simple, practical strategies parents can adopt to introduce new foods and improve their child’s nutrient intake through dietary changes. For example, adding zinc drops to favourite foods, as well as using probiotics to support gut health and digestive enzymes to improve nutrient absorption. She also shares insight into the role of using supplements as "scaffolding" while working on longer-term dietary changes, particularly for fussy eaters.

Blood sugar can also affect brain function and behaviour in children with ADHD, so Lucinda briefly explains how this can look. She also shares key information around the benefits of a high-protein, high-fat diet to help children maintain stable blood sugar levels and improve their focus and concentration. 

This episode is a must-listen for parents looking to understand how diet and nutrition can help their children with ADHD, especially if they are fussy eaters, and offers practical, achievable solutions, rather than yet another guilt trip!
