Summarize this article:

Persons with ADHD tend to have lower serotonin and dopamine levels. Many people experiment with changes in their diet in order to counter-effect these deficiencies to some extent. Experts recommend a complex-carb diet to boost serotonin for improved mood, sleep, and appetite.  Skip simple carbs (sugars, honey, jelly, candy, soda, etc.) ) that cause a temporary serotonin spike.  Instead, choose complex carbohydrates such as whole grains, green vegetables, starchy vegetables, and beans.  These all act as an energy “time-release.” Eat a protein-rich diet that includes several proteins over the course of the day to keep dopamine levels high.  This will help you improve your focus. Proteins include meat, fish, and nuts, as well as several foods that double as complex carbs: legumes and beans. ADHD experts recommend improving the brain by avoiding “bad fats” such as those found in trans-fats and fried foods, burgers and pizzas. Instead, choose omega-3 fats from salmon, walnuts, avocados and more.  These foods may help lower hyperactivity while improving organizational skills. Seafoods, poultry, fortified cereals and other foods with a high zinc content or taking zinc supplements are linked to lower levels of hyperactivity and impulsivity in some studies. Don’t forget that some spices do more than add flavor. For example, saffron counters depression, while cinnamon helps with attention. Some studies show that eliminating wheat and dairy, as well as processed foods, sugars, additives and dyes (especially red food coloring), can have a positive impact on behavior in children with ADHD.   While not everyone will be willing or able to go to that length, some experimentation may produce improvements that make a difference. Be certain to run any major changes in diet by your doctor. This includes changes related to vitamins and supplements. Ask your doctor about any conflicts that could negatively impact your ADHD medication. Your doctor can also suggest recommended dosages of various supplements and warn of possible side effects.   For instance, melatonin may improve sleep in persons with ADHD, but it might also induce vivid dreaming which may be unpleasant.

Summary:
Eat complex carbohydrates to boost serotonin levels. Improve your focus by eating more protein. Choose omega-3 fats. Increase your intake of zinc. Add spices to your food. Experiment with eliminating certain foods. Talk to your doctor about dietary changes.
