Attention Deficit Hyperactivity Disorder (ADHD) is a condition that affects behaviour and is characterised by inattentiveness, impulsivity and distractibility. For many children, ADHD co-exists with some form of anxiety.



The nutritional consequences of ADHD are far ranging and there is a huge amount of information out there making it difficult to separate fact from fiction. To make it more complicated, the issues vary according to the individual, as well as their environment and family circumstances. As regulated healthcare professionals, Dietitians must keep up to date with the latest evidence and our role is to tailor this to your personal circumstances. In this post I have tried to cover some general tips on the topics that frequently arise in my practice.

Mealtimes and eating out.


Distractibility can be a real problem for some children, making sitting at a table for a family meal difficult and eating at a restaurant a stressful experience. Observe your child really carefully to work out what conditions help them remain calm and what factors cause distraction during a meal. This will be different for every child, but working this out may help you alter the environment to meet their needs. Avoid comparing yourself to other families or social expectations as your family has its own specific needs.

Anxieties around picky eating


It is not uncommon for children to go through stages of picky eating, but these can be particularly difficult when behaviour is challenging to manage. To avoid creating a battleground over food, stick to a three meal a day and three snack a day routine. Keep mealtimes to 30 minutes and present and clear away uneaten food without judgement. Keep rewards for good behaviour unrelated to food to prevent ‘treat’ foods having emotional significance. Similarly with-holding food to manage behaviour is likely to raise tensions further and may result in inadequate nutrition.

Medications

Loss of appetite is a common side effect of some of the drugs used to treat ADHD. For those who experience this, provide a good meal before taking medication and after it has worn off in the evening. During the rest of the day, your child will need small regular snacks to keep their blood sugars and brain chemicals stable.

Planning and organisation of meals

ADHD is associated with difficulty managing executive functions such as planning and organisation, skills that are key for shopping, cooking and eating well. Many adults and older children with ADHD show greater reliance on less healthy convenience foods and take-aways. As children grow and become more independent it is important to think ahead with strategies to plan meals to remain healthy.

Foods that may make symptoms worse


You may read about foods that are said to make ADHD behaviours worse, such as sugar, artificial sweeteners and and some colourants and preservatives [1].

The science doesn’t support the theory that sugar or artificial sweeteners make ADHD symptoms worse. That said, we know that limiting free sugar can prevent weight gain and tooth decay. Government guidelines recommend all children aged 4 to 6 years old should have no more than 5 sugar cubes and children 7 to 10 years should have no more that 6 sugar cubes of free sugar a day [2].


Recent research shows that there is a possible link between some artificial additives and hyperactivity, however this is no worse in ADHD than the general population. The British Food Standards Agency advises parents to consider avoiding a list of 7 additives if you think this may be an issue. If you think there may be a link, it is a good idea to keep a food and symptom diary.

Treatment with elimination diets has shown some limited success and is based on the idea that ADHD behaviours may be triggered by food sensitivity as an immune reaction to food [3-4]. If you do try a restrictive diet it is important you do this under medical or dietetic advice for a limited time only to ensure growth and nutritional adequacy is not affected.

Foods that improve symptoms


Additional zinc, vitamins A and C and fish oil supplementation have been studied to see if they improve symptoms however there is little robust evidence to support this [1,5]. A dietitian can help ensure your child has a balanced diet and receives all the nutrition required from food sources.


There is building evidence that the quality of our overall diet is not only critical for our physical health, but has significant effects on our mental wellbeing and mood. Of particular interest is the relationship between the food we eat and the bacteria in our gut, or the microbiome. On a mechanistic level there is a lot of evidence that complex communication occurs between the microbiome, our gut and our brain which alters our mood and our behaviour [6]. Improving our diet quality has been shown to be an effective treatment for mental health conditions [7] and may be a useful adjunct to manage anxiety.



The experience of ADHD is different for every individual and is dependent on the environment in which we live. If you would like tailored nutrition advice for ADHD, please get in touch. After a full assessment of your needs, I can help make a personalised plan and provide ongoing support as needed.

There has been a great deal of discussion about the effects of the most recent winter lockdown on our eating habits.

  • The media widely reported a joint Ipsos Mori and King’s College survey of 2000 people indicating almost half had gained weight during this period.

  • Marcus Rashford placed a spotlight on the importance of free school meals and problem of holiday hunger for those at risk of food insecurity.

  • BEAT, the country’s leading Eating Disorder charity, reported a rise of 73% increase in people accessing their services.


But it’s not been bad news for everyone. We also hear about people who have had more time to shop locally, cook from scratch, eat fewer take-outs or cook and eat together more as a family.


This illustration shows some of the ways the winter lockdown has changed the nutrition of young people.





Bite sized tips


Nobody wants to make this lockdown more difficult than it already is, so self-compassion is key.


Tiny habits

Make small goals that are easy to meet, so you feel good about the change you have made. For example, if the goal is to drink more water, start with one glass first thing every morning. If you achieve it and feel good, you will be more likely to carry on or even drink more.


Focus on the positive

Rather than looking at the things that aren’t going so well and are difficult to stop or provide a coping strategy at a difficult time, focus on something positive. This might be eating more vegetables and fruit or learning how to cook a new savoury dish.


A note on nutrition and mental health

National data indicates a rise in mental health concerns of the nation and this can affect eating habits and gastrointestinal problems. There has also been a rise in the this sector for urgent referrals for Eating Disorders such as Anorexia Nervosa and Bulimia Nervosa. Working in an in-patient Child and Adolescent Mental Health (CAMHS) hospital, this has been a trend that I have witnessed.


Eating Disorders are easier to treat if detected early, so if you have noticed changes in eating or exercise behaviours that concern you, please get in touch to talk these through, or contact your GP.
