Diet may play a significant role in managing symptoms in children with ADHD. Adding certain foods and nutrients that may boost brain function, eliminating foods that seem to worsen ADHD symptoms, and trying other diet and nutrition tips to improve your child’s diet may all help with ADHD.
1. Eliminate Processed Foods
Recent research has shown that people with ADHD are more likely to be sensitive to food dyes and other additives typically found in processed foods. “The more you stick to whole foods, the better,” says Sally Hara, MS, RD, a spokesperson for the American Dietetic Association and a nutritionist in Kirkland, Wash.
“Parents today are into convenience such as packaged food and fast food,” says Elizabeth Strickland, MS, RD, an integrative dietitian specializing in ADHD and autism in San Antonio, Texas. “But food is critical for brain function. Natural vitamins and natural fiber are important. Make time to cook real food.”
One strategy is to cook dinners for the first few nights of the upcoming week on a Sunday. Then all you’ll need to do is reheat your homemade meals. Another way to get kids into eating fresh food is to involve them in growing a vegetable garden. “Kids are more likely to eat things they’ve grown,” says Hara.
2. Put Protein in Your Kids’ Diet
Children with ADHD need protein along with complex carbohydrates, especially at breakfast, says Hara. She says studies have shown that kids who eat sugary carbs for breakfast, such as a donut, were fidgety and hungry before lunch. Switching to whole grains is good, but not good enough — youngsters who ate protein were the ones who didn’t have these problems. By combining an immediate source of energy — the carbs — and a later source — the protein, kids were able to stay still and focus more, says Hara. Ideas for a balanced breakfast for a child with ADHD are scrambled or boiled eggs or a piece of turkey on whole-grain toast.
Note that stimulants such as methylphenidate (Ritalin) can decrease appetite, which can then result in a drop in blood sugar and affect concentration and attention, and they also don’t work as well when kids haven’t eaten — another reason breakfast is important. If your child is not hungry for a full meal at breakfast, try a smoothie with protein powder or, as a last resort, an energy drink, says Hara.
3. Think Organic
A recent study found that kids with high levels of common pesticides in their urine were significantly more likely to have ADHD than kids whose pesticide levels were lower. “Organic is definitely a benefit,” says Hara. “It depends on the individual’s sensitivity. I can’t see a downside to organic, and it takes out any possibility of chemical reaction.”
Adds Strickland, “Buy organically grown fruits and vegetables as much as you can afford. Pesticides contain arsenic, which is a neurotoxin that damages the brain. It can cause problems with attention, hyperactivity, and aggression.” Pesticides also contain lead, which can lead to ADHD and impulse control problems even in small amounts.
4. Avoid Trigger Foods
Recent research has shown that diet contributes to ADHD, says Strickland. Elimination diets, such as the
Feingold Diet, can help parents pinpoint foods that may be contributing to a child’s ADHD symptoms. “Certain foods can cause headaches, GI [gastrointestinal] tract problems, and itchy skin,” says Strickland. These symptoms can then become a part of everyday life.
Eliminating foods with artificial colors, flavors, and preservatives from a diet and then gradually adding foods back one at a time can help parents identify those causing problems, says Strickland. A
gluten and casein-free diet can be helpful for a child with gastrointestinal problems and headaches, she says. Casein is a protein found in dairy foods.
Many kids on such a diet find that they have improved gastrointestinal function, better sleep (since tummy troubles can cause kids to wake up throughout the night), and improved behavior and concentration. Today, making substitutions for gluten in a child’s diet is easier than it used to be. “Start introducing new foods such as gluten-free pasta, rice flour, and corn tortillas,” says Hara.
Another tip to keep in mind is that a prolonged drastic elimination diet may not be necessary. “The Feingold Diet removes every possible trigger,” says Hara. “But why eliminate things that may not be a problem? Gradually, over time, you can add things back slowly.”
Hara cites her own son, 12, who was diagnosed at age 5 with ADHD. “He can tolerate milk once a week, but not more than that,” says Hara. “Kids can eat up to their tolerance level.”
Another way parents can help identify trigger foods is by carefully observing their child. “When my son was little he would say ‘my head hurts’ after five minutes of reading,” says Hara. “But when we took the offending foods out, we realized it was his tummy that hurt. For kids, we may think it’s picky eating when it’s really careful eating. Their mouth may itch or their tummy may feel upset.”
5. Consider Supplements
Strickland says that children are not getting enough of the nutrients that are important for brain and nervous system function. Fewer mothers are breastfeeding, she says, and fewer people are eating fish because of concerns about contaminants such as mercury. “Today’s diet is deficient in omega-3 fatty acids,” Strickland says.
This lack of brain-boosting nutrients is compounded by the fact that people eat too much pre-packaged food high in preservatives and trans fats. “Trans fats interfere with omega-3 fatty acids in our body,” says Strickland. “Multivitamins and supplements are critical. You see improvement in symptoms in children with ADHD.”
The B vitamins and B6 in particular along with omega-3 fatty acid supplements may help. Talk to your child’s pediatrician and nutritionist first and, if you decide to try them, make sure the vitamins are free of artificial colors and flavors and look for a fish oil supplement with no mercury, says Strickland.
6. Evaluate Caffeine
As surprising as it may sound, a stimulant like caffeine can be good for a child with ADHD. “For my son, caffeine knocks his behavior into place,” says Hara. She sometimes gives her son a Coke after school. It can help him focus on his homework and improve his concentration, and it wears off in time for bed.
When looking for solutions to manage your child’s ADHD symptoms, experts say that patience and perseverance are crucial. “With kids, you can’t change a diet overnight and you can’t expect behavior to improve immediately,” says Hara. “Work with a dietitian who’s trained in food sensitivity or ADHD.”
