Jake works with children and adolescents across a full spectrum of nutrition needs, from foundational healthy development to specific clinical conditions with significant nutritional dimensions.
ADHD Nutritionist
Attention, focus, and emotional regulation all have direct nutritional drivers: iron, zinc, omega-3s, and magnesium directly affect dopamine and noradrenaline. Jake builds ADHD-specific nutrition plans for children and teenagers that address the biochemistry, not just the behaviour.
Teenager Nutritionist
Puberty doubles the demand for protein, iron, zinc, magnesium and vitamin D, and most teenagers fall short. Jake builds teenager nutrition plans that fuel growth, stable energy and strong daily performance through every stage of adolescence.
Children’s Nutritionist
Fussy eating, low energy, slow growth or recurring tummy issues are rarely about willpower. Jake builds children’s nutrition plans that steady eating patterns, support growth and build a healthy relationship with food from the ground up.
The nutritional demands of growth, cognitive development, and hormonal maturation create requirements that are distinct, and in some cases dramatically higher, than adult needs. Iron, omega-3 DHA, zinc, calcium, vitamin D, and iodine are all critical at specific developmental stages in ways that don’t apply to adults. Clinical nutrition for young people requires age-specific, development-aware expertise.
Jake’s approach to youth nutrition is practical by design, built around the real challenges of feeding children and teenagers, working with families on achievable dietary changes rather than unrealistic ideals.
78%
Children with ADHD have been found to be deficient in Vitamin D
Vitamin D is essential for children because it supports bone growth, immune strength, and healthy muscle function.
90%
Adolescents with ADHD have inadequate omega‑3 intake
Most teens fall far below recommended DHA and EPA levels, reducing cognitive endurance and working memory.
60%
Children on stimulant medication experience appetite suppression
More than half show reduced daytime intake, leading to inadequate energy availability and increased risk of micronutrient deficiencies.
Poor school performance
Difficulty focusing, learning, or retaining information, particularly when combined with sleep issues or dietary patterns.
Fatigue & low energy
Persistent tiredness that affects school, sport, or mood. One of the most common presentations of iron deficiency in youth.
Digestive complaints
Constipation, bloating, recurrent stomach pain, or food aversions, common in children with gut health issues or food intolerances.
Mood changes & irritability
Emotional dysregulation, low mood, or anxiety in young people, all with well-documented nutritional dimensions.
Slow growth or underweight
Growth concerns identified by a paediatrician, or persistent difficulty maintaining healthy weight in the context of adequate food availability.
Poor immune function
Frequent illness, slow recovery, or recurring infections, often linked to zinc, vitamin D, or gut health deficiency.
ADHD diagnosis
A formal or suspected ADHD diagnosis, the nutritional dimensions are well-evidenced and consistently undertreated.
Picky eating
Limited food variety creating measurable nutritional gaps in vitamins, minerals, or food groups critical for development.

Jake works with children, pre teens and teenagers, tailoring his approach to the developmental, emotional and nutritional needs of each age group.
He supports young people ADHD, eating disorders, anxiety related eating patterns, gut issues, growth and energy concerns, and general nutrition challenges.
His work always includes parent involvement and coordination with existing healthcare providers so progress feels safe, structured and consistent for your child or teenager.
Yes. Jake works collaboratively with paediatricians and child psychologists.
Each clinician supports a different part of your child’s health, and Jake’s nutrition work is designed to fit seamlessly alongside medical and psychological care.
Paediatricians oversee diagnosis, investigations and medical monitoring, while child psychologists support emotional, behavioural and developmental needs.
Jake focuses on the nutritional, metabolic and daily patterns that influence mood, energy, growth, eating behaviours and overall stability.
When these areas are aligned, children and teenagers progress more smoothly and feel more supported across all parts of their care.
Yes. Nutrition plays a major role in both eating disorders and ADHD because it directly influences the brain, the nervous system, appetite regulation, mood stability and daily behavioural patterns.
In eating disorders, targeted nutrition helps stabilise energy, reduce extremes in hunger and fullness, support the gut, rebuild metabolic function and calm the physiological stress response that keeps symptoms active.
In ADHD, nutrition supports neurotransmitter pathways, blood sugar stability, focus, emotional regulation and predictable eating patterns.
Jake is flexible. Some families prefer that their child or teenager attends the consultation because it allows Jake to understand their patterns, routines, energy, mood, appetite and day to day challenges directly.
For younger children, the session can be a mix of parent discussion and child involvement so the process feels safe and age appropriate. For teenagers, being part of the consultation often helps them feel included, respected and supported in their own health journey.
Parent involvement is always included, and Jake guides you on the best structure for your child’s age, needs and comfort level.
No. Your child or teenager will not be asked to change everything they eat. Jake’s approach is flexible, realistic and designed to meet young people where they are. The focus is on understanding their current patterns, identifying what is driving their symptoms or challenges, and making targeted adjustments that
feel achievable rather than overwhelming.
Most children and teenagers actually gain more clarity, confidence and predictability around food without needing a complete overhaul.
Changes are introduced gradually, with parent involvement and a clear plan that supports growth, energy, mood and daily functioning while keeping their diet as broad and enjoyable as possible.
Clinical nutrition is one of the most overlooked pillars in supporting the health of children and teenagers. Jake’s world‑class expertise in paediatric nutrition allows your child or teenager to rebuild optimal nutritional status, strengthen long‑term health, and establish the foundations for lifelong wellbeing.
