Cut Back on Chemicals
Several studies suggest that artificial additives make non-ADHD children more hyperactive, and make hyperactive children worse. The European Union requires a warning label on food packaging that contains additives: "This food may have an adverse effect on activity and attention in children." Gatorade, cheese puffs, and candy are typical examples of foods containing artificial colors and preservatives, but additives and colors can be found in other foods.
The first step in avoiding additives is to read food ingredient labels until you've found a wide range of foods that are additive-free. In most cases, fresh, unprocessed foods are your best bet, as they contain few additives.
However, these days you can find bread, cereal, cookies, pizza, and just about anything else made without additives. Avoid colorful cereals, like Fruit Loops and Lucky Charms. Cheerios are better, and lower in sugar. Substitute 100-percent fruit juice for soft drinks and fruit punches, most of which are artificially colored and flavored.
