ADHD
Lifestyle modifications
NUTRITION
Dietary patterns: Weak evidence suggest that a diet high in refined sugar and saturated fats increase the risk of ADHD, while a healthy diet characterized by a high intake of fruits and vegetable may prevent ADHD and hyperactivity (2)
Vitamin D: Supplementation as an adjunct therapy to methylphenidate may improve symptoms (5)
Omega 3: There are mixed findings on the effect of supplementation with omega 3 fatty acids on ADHD symptoms (3, 4)
PHYSICAL ACTIVITY
Exercise may reduce cognitive symptoms among people with ADHD (1)
