7. Caffeine
Caffeine is a natural stimulant that can adversely affect the central nervous system and heart when consumed in large amounts. The American Academy of Pediatrics (AAP) advises against the use of caffeine or caffeinated beverages, such as soft drinks, for children under five years of age. Although caffeine has shown effectiveness in improving functioning and reducing hyperactivity, it can amplify the effect of ADHD medications, and its excessive intake can have side effects, such as appetite suppression and insomnia, which can worsen ADHD symptoms. Thus, all children should avoid caffeine and caffeinated products. As for the use of caffeine for improving ADHD symptoms, it’s a matter one should discuss with a pediatrician.
8. Allergens
Some children with ADHD may have sensitivity or intolerance to specific foods, such as salicylate-containing foods (tomato and grapes) and common allergens such as milk, soy, seafood, wheat, and peanuts. A cross-sectional study conducted on school children concluded that “early food allergy is associated with ADHD”. Thus, eliminating foods that cause sensitivity may help. However, this needs to be done with close pediatric guidance as the intervention may not be helpful for children with ADHD who aren’t allergic or sensitive to foods.
