The brain’s growth is mostly complete by adolescence, but a lot of its vital connections are still being made during the teen years. Next to infancy, adolescence is a period that requires a nutritious diet for healthy brain growth, especially if this brain has ADHD. Diets of the average teenager, however, tend to be sorely deficient in important nutrients and fatty acids.  Teens either eat foods with high levels of hydrogenated fats and saturated fats, or they restrict their food intake in order to stay trim. Here are some ADHD diet tips to help your teenager develop healthy eating habits.

Practice what you preach

Instead of telling your child what foods to eat, model healthy eating habits by practicing what you preach. Take your child to the supermarket with you and demonstrate how to buy nutritious foods. Point out which types of foods are just empty calories and which ingredients trigger ADHD, such as artificial coloring, preservatives, and flavoring.  Encourage your child to help plan meals at home so that he or she becomes more motivated to eat healthy.

Say no to processed foods

Resist the temptation to buy frozen foods, canned foods, and other highly processed foods. Not only do these foods offer low nutritional value; they are also loaded with harmful ingredients that aggravate ADHD symptoms.  For instance, processed foods contain high levels of hydrogenated oil, which can be incorporated into the brain structure. Once in the brain, these oils make neuron membranes rigid and inefficient at transmitting and receiving neurotransmitters, which affects brain function and behavior.

Use teenage thinking as a weapon

Teenagers are conscious about their physical appearance, and you can use this to your advantage when it comes to nutrition. Talk to your child about the relationship between a healthy diet and acne-free skin, or say that empty calories will only facilitate weight gain.  This type of teaching uses the idea of “relevance”. In order for a teenager to accept the message, he or she has to believe that it has a direct impact in their life. Be specific – talk to your child about how eating well can improve their growth, their sports performance, their attention span, or whatever issue seems to be important to your child at the moment.

Here are some of the specific nutrients needed by your ADHD teen.

• Iron. Teens with ADHD, especially menstruating girls, tend to be low in iron. Addressing this deficiency is important, because iron aids in the production of neurotransmitters.
• Zinc.  The trace mineral zinc is responsible for brain wave processes, producing serotonin, and vitamin B6 metabolism, to name a few. Dark meat, oysters, and legumes are excellent sources of zinc.
• Calcium. Besides aiding growing bones, calcium helps produce neurotransmitters and aids in vitamin absorption and enzyme digestion.  Instead of adding more milk and dairy to your child’s diet, use dark green vegetables like broccoli, which are healthier sources of calcium.

Exciting news for parents who want their kids to try an ADHD diet! A new study confirms once more that ADHD symptoms can be reduced by eliminating foods that trigger them. The study on the restricted elimination diet (RED) was recently published in The Lancet, with very promising results.

How do ADHD diets work?

If you have been following the UnRitalin Blog for some time, you might already be familiar with how ADHD diets work to relieve symptoms. But for the benefit of those who are new, let me explain the relationship between food and ADHD.  While ADHD is known to be the result of a neurotransmitter deficiency, many cases of childhood ADHD are actually allergic reactions to certain types of food. Dr. Doris Rapp explains that allergic reactions are not limited to familiar symptoms like coughing or watery eyes; some allergies affect how the brain works, which manifests itself as problematic behavior. If you click on the link, you’ll see an amazing video that demonstrates how exposure to allergens can completely transform a child’s behavior.

Most ADHD diets are designed to eliminate foods known to trigger allergic reactions. The tricky part about using a diet to treat ADHD is that each child is sensitive to different foods. For instance, while foods with gluten and casein are generally known to trigger ADHD symptoms, some children may be allergic to certain fruits and vegetables on top of gluten and casein. ADHD diets are not a quick fix; every child has to go through a trial and error process to determine which foods have to be eliminated.

Restricted Elimination Diet

The study on the restricted elimination diet shows more evidence that removing certain foods can indeed improve the behavior of children with ADHD. The study was led by Jan Buitelaar of Radbound University and involved the participation of one hundred children with ADHD between the ages of 4-8. The children were equally divided into two groups – one group was given a general healthy diet, while the other group was given a diet that was restricted to certain foods. These foods included rice, white meat, water, and fruits and vegetables that are least likely to cause allergies. Foods with tomatoes, eggs, oranges, dairy, and wheat were also kept out of the second group because they are related to food intolerances or allergies.

In the second group, 41 of 50 children completed the five-week period, and 32 of the 41 children (78%) responded well by having fewer symptoms.  Not only were their ADHD symptoms less pronounced, but they also had fewer symptoms of oppositional defiance disorder, which is characterized by temper tantrums, stubbornness, and defiance.

All the children who completed the five-week period went on another diet where the allergenic foods were reintroduced. After another trial, the symptoms returned in the children who showed positive improvements.

Going on an ADHD diet

Parents who are looking for an alternative ADHD treatment might find success in doing an ADHD diet. However, it is important that you do the diet with the help of a doctor or nutritionist. Some ADHD diets require the elimination of nutrient-rich foods, which can increase the risk of malnutrition if a balance of nutrients is not achieved.  ADHD diets will also require the involvement and participation of the entire family. In order to keep your child from getting tempted by the eliminated foods, everyone in the family has to go on the diet as well.  Getting used to a restrictive new diet will take some adjustment, but I never fail to get surprised by children’s high response rate to an ADHD diet.

Getting your child to give up favorite foods for an ADHD diet is tricky, and the holiday season might make it more difficult.  The last few weeks of the year will be filled with dinner parties, family reunions, and other types of gatherings centered on food.  Your child might feel left out when cousins enjoy forbidden holiday treats, and relatives won’t understand why he or she can’t have just one tiny cookie.  It may not be a good idea to take a break from your child’s diet and start from scratch after a few weeks, but here are some tips that will make eating a fun occasion for your child during the holidays.

Host the party

Offer to host this year’s holiday dinner party or family gathering.  This way, you can make sure that all dishes being served is allowed by your child’s diet, be it the Feingold diet or the gluten-free casein-free diet. If your house cannot accommodate all your guests, offer to prepare the food for the party instead.

Look for alternatives to forbidden ingredients

The holidays won’t be as magical for a child without a steaming mug of hot chocolate, gingerbread cookies, or candy cane.  The problem is that these foods are normally eliminated in most ADHD diets.  However, you can easily give your child some holiday treats if you can find additive-free, gluten-free, or casein-free alternatives to these unwanted ingredients.  Gluten-free casein-free cookbooks are easily available in all bookstores, but you can also find useful recipes when you search online.

Consider a desensitization treatment

If you do not have time to host parties or prepare holiday feasts, consider a desensitization treatment to make your child less sensitive to food allergens. Look for chiropractors or doctors who specialize in enzyme therapy, food allergy elimination, or organ-specific detoxification. A caveat: these techniques won’t work overnight; it may take several months before you see any noticeable results.

Ask for support

Support from family and friends can make it easier for your child to stick to a diet but it’s likely that your relatives don’t understand why your child can’t just take a pill. When planning the holiday festivities, take time to educate them on the logic behind your child’s diet – certain food substances or ingredients influence brain activity and trigger hyperactive behavior, aggression, or inattention.

Last week, I talked about how the number of children diagnosed with ADHD has skyrocketed over the last few years, and posited some possible explanations for this phenomenon.  While some might argue that ADHD awareness and overeager doctors contributed to this increase, a new study published in the journal Pediatrics finds that diet and lifestyle parallels the high rate of childhood ADHD cases today.

This study, which was done by researchers from University of Rochester Medical Center, looked at 201 children and adolescents between the ages 10 and 18.  All children were referred the URMC’s Children’s Hospital hypertension clinic, and it was found that 101 had sustained high blood pressure or hypertension.  We’re all familiar with how hypertension increases the risk of heart disease among adults but in young children, high blood pressure has a stronger impact on their mental development and functioning.  Not surprisingly, 28% of the 101 children were found to have ADHD and learning disabilities.

Children with ADHD used to be excluded from studies like this because the medications they take may increase blood pressure. However, the researchers included ADHD children this time because they wanted to see if high blood pressure impaired their mental functioning. What’s interesting is that when ADHD was removed from the picture, hypertension was still related to a higher rate of learning disabilities in children.  This suggests that high blood pressure may contribute to mental development problems among children.

Hypertension in infants is usually caused by problems with the kidneys or heart, or premature birth. With proper management, blood pressure normalizes during early childhood. However, at least 3% of children today have high blood pressure, and many of these cases are not due to birth complications.  Many adolescents and teens with hypertension do not have other health problems, but they do have a family history of hypertension and live an unhealthy lifestyle characterized by excess weight, bad diet, lack of physical activity, and stress.

Fortunately, it’s not difficult to prevent hypertension in children, even if the child has a family history of the condition. These preventative measures are also often used as natural ADHD treatments:

• Regular exercise not only keeps ADHD symptoms at bay; it strengthens the blood vessels and helps control weight.  Though organized sports is the most common way to get regular exercise, unstructured activity like running, biking, or skating also works for kids with ADHD.
• Avoid high-fat and high-sodium foods – the two culprits behind high blood pressure. Give your child healthy meals with low-fat products, fruits, vegetables, and fish.
• Supplement meals with omega-3 essential fatty acids from fish oil. For ADHD kids with hypertension, omega-3 fats serve a double purpose – it reduces ADHD symptoms by forming the structure of the neuron membranes and facilitating neurotransmitter communication, and it prevents hypertension by keeping blood vessels supple.
• Get a regular check-up. A child’s blood pressure naturally increases with age, and a doctor can tell if your child’s blood pressure is normal for his or her age, height, and weight.

We’ve long suspected that the typical Western diet might be the reason why so many children are diagnosed with ADHD today.  The brain requires a healthy number of nutrients, essential fatty acids, and amino acids to release and regulate neurotransmitters (brain chemicals responsible for mood, attention, concentration, and impulse control).  Although these nutrients can be obtained from a healthy diet of fruits and vegetables, the typical Western diet has little room for such healthy options.  Why? This type of diet prioritizes the convenience of cooking rather than nutritional value. Unfortunately, these fast food meals are high in fat, refined sugar, and sodium, and offer few nutrients in return. Can such a diet be responsible for the increase of ADHD epidemic among children and teens today?

An exciting new study from Perth’s Telethon Institute for Child Health Research may have just confirmed the link between ADHD and Western-style diets.  This study, which was published in the Journal of Attention Disorders, examined the dietary habits of 1,800 adolescents from the Raine Study, an ongoing long-term health research project. The Raine Study has been tracking the health and diet of these kids since they were born in the late 80s and early 90s.

The diets of the adolescents were classified into two groups. The “Healthy diet” group is characterized by high intakes of fresh vegetables and fruits, fish, and whole grains. This diet tends to be higher in fiber, folate, and omega-3 essential fatty acids.  The “Western-style diet” is characterized by fast food takeout, fried food, refined foods, and processed foods. This diet is higher in total fat, saturated fat, sodium, and refined sugar.  The dietary patterns were then compared to whether the individual received an ADHD diagnoses before the age of 14. In this study, 115 adolescents were diagnosed with ADHD – 24 girls and 91 boys.

After adjusting the data for other social influences, it seems that those in the Western diet group had double the risk of having an ADHD diagnosis compared to those who ate healthier foods. Lead researcher Dr. Wendy Oddy says, “When we looked at specific foods, having an ADHD diagnosis was associated with a diet high in takeaway foods, processed meats, red meat, high fat dairy products and confectionery.”  She also pointed out that the typical Western diet does not provide the essential micronutrients required for proper brain function, especially for tasks like concentration and attention. Not to mention that Western diets contain more artificial additives, flavors, and food dyes, which have been linked to the onset of ADHD in the past. Finally, Dr. Oddy suggests that impulsivity, a hallmark symptom of ADHD, may also lead to poor dietary choices like quick snacks.

Although the study was not able to determine a causal relationship (e.g. researchers are not sure if a poor diet leads to ADHD or if ADHD leads to poor dietary choices), there is definitely a link between ADHD and the typical Western diet.  Here’s a little experiment you can try: remove junk food, processed food, fast food, and fried food from your child’s diet for a week. Replace these with lots of green leafy vegetables, fresh fruits, and non-processed meats.  Are there any noticeable improvements in behavior and overall symptoms?

It’s quite shocking to see how eating the wrong food has such a profound effect on a child’s personality, outlook, and behavior. It’s just as amazing to know that getting rid of the allergenic substance was enough to turn a screaming, flailing child into a calm, peaceful one.

There are two ways to find out if your child’s ADHD symptoms are caused by allergies. The first is through a specialized allergy testing, which is only available among alternative medical practitioners. However, these tests have a serious limitation – although they can confirm any brain-based allergic reactions, they cannot identify exactly what food or substance your child is allergic to. The best way to go about doing this is to go on the allergy diet proposed by Dr. Rapp, also known as the rotation diet. It might be difficult to get used to the rhythm of a rotation diet at first, but you can stop it as soon as you have identified the food your child is allergic to. Start by rotating wheat products and dairy products as these contain gluten and casein, two proteins that are notorious for their impact on behavior and brain activity.

If your child is anything like the children you’ve seen in the video, and if nothing you have done made a difference in your child’s behavior, try to pick up a copy of Dr. Rapp’s book “Is This Your Child?”. This 600-page book is one of the comprehensive resources on allergies, ADHD, and other realistic solutions that will get rid of your child’s problematic behavior.

ADHD cannot be diagnosed by checking off a laundry list of symptoms because many disorders often cause similar problems. Celiac disease is one such overlooked disorder. You might have been aware that food intolerances and intestinal problems have a hand in causing ADHD symptoms. Celiac disease is a condition where a person is intolerant to the plant protein gluten, which is found in wheat and wheat products. When a child with celiac disease eats pizza, pasta, or any food with wheat in it, the immune system reacts by damaging the upper region of the small intestine. The initial damage only amounts to minor inflammation but if the child continues to eat foods with gluten, painful symptoms and impaired nutrient absorption can occur.

The latter effect is particularly significant. In our previous articles, we have shown how deficiencies in zinc, magnesium, calcium, and other nutrients can trigger or aggravate ADHD symptoms. Iron in particular has been found to be useful in suppressing ADHD symptoms, assuming that there is indeed an iron deficiency. Research shows that a gastro-intestinal system damaged by celiac disease can lead to an iron deficiency, which can complicate things for a child with ADHD.

Celiac disease has also been linked to other common psychological conditions like chronic depression. This could be due to the fact that the gastro-intestinal tract produces 90% of the body’s serotonin, the neurotransmitter responsible for mood control and feelings of happiness. Another possible reason is that a damaged gastro-intestinal tract might be unable to absorb adequate amounts of tryptophan, the amino acid precursor to serotonin. Tryptophan is found in high concentrations in meats like turkey.

Given that ADHD has so many potential causes, it’s likely that your child’s symptoms may be caused by an underlying factor like celiac disease. You can confirm your suspicions through a combination of lab tests. The first step to a celiac disease diagnosis are blood tests designed to measure levels of a certain auto-antibody. Unlike antibodies, which attack foreign substances and viruses in the body, auto-antibodies target the body’s own tissues. The auto-antibodies measured for celiac disease are immunoglobulin A, anti-endomysium antibodies, and anti-tissue transglutaminase. The blood work might also include a complete blood count to rule out anemia. Other tests you might want to include are nutrient element test to check for vitamin deficiencies and an intestinal permeability test with stool analysis.

The good news is that the effects of celiac disease can be avoided by a gluten-free diet. An Italian study on celiac patients with ADHD symptoms discovered that eliminating gluten for six months reduced the severity of ADHD symptoms. Although the prevalence of wheat products in the typical Western diet might be hard to implement the gluten-free diet on a child, ADHD cookbooks can help you find alternative ingredients for gluten-free cooking and baking.

In our Article Library, you’ll find several discussions on various nutritional interventions for ADHD. Although vitamin C is known more for its immune-boosting and antioxidant properties, some studies suggest that it may play an important role in managing hyperactivity, impulsivity, and inattention. Before you get excited and start buying vitamin C supplements, take note that vitamin C works more as a secondary treatment that boosts the efficacy of supplements and dietary methods; in other words, it should not be used as a single, stand-alone treatment. Although some of its speculative benefits still need to be confirmed by further studies, it seems like maintaining or increasing vitamin C levels can reduce ADHD symptoms in five ways:

Protects omega-3 fatty acids from oxidation

Omega-3 fatty acid supplements containing DHA and EPA are known to improve brain function among individuals with ADHD. However, one of the main problems of supplementing with fatty acids is that they are prone to oxidation after the slightest exposure to sun, air, or light. Oxidation basically means that the fatty acids break down, go rancid, and no longer contain their nutritional benefits. A natural antioxidant can prevent this problem, but vitamin C is actually not the best choice where fatty acids are concerned. Vitamin C is a water-soluble vitamin, which means it has limited effects on a less water soluble substance like omega-3 fats. However, it does boost the levels of other important antioxidants like glutathione and vitamin E, which are better equipped to protect omega-3 fats from oxidation. It’s also important to note that vitamins C and E work very well as an anti-oxidant team.

Neuroprotective properties

Did you know that the brain’s nerve endings have the second highest concentration of vitamin C in the body? (The first is the adrenal glands.) New research shows that vitamin C performs a strong protective role in the brain, especially when used with vitamin D. It protects against a specific type of oxidative damage called ischemia, which causes reduced blood supply to the brain. This is important to children with ADHD because ischemia is actually one of the lesser known causes of ADHD, especially during a child’s early years. Ischemia can interfere with the dopamine receptors in the brain, causing symptoms like poor attention span and slow reaction time.

Neutralizes the effects of lead

Current research shows that ADHD-like behaviors and symptoms may be connected to increased lead levels. Vitamin C can reduce lead’s negative effects on memory and learning, especially when used together with zinc, methionine, taurine, and glycene.

Improves absorption of minerals

Deficiencies in zinc, iron, and magnesium are just some of the nutrition-related triggers of ADHD. Researchers hypothesize that vitamin C’s ability to fight off the effects of lead has to do with the way it increases iron absorption, especially if iron is deficient. Take note that vitamin C can possibly work as a pro-oxidant if found at low levels in the body; in higher levels, it has an anti-oxidant effect.

Regulate blood sugar levels

Some research suggests that children with ADHD have low glucose metabolism in certain regions, especially those that control attention and movement. This effect seems to be more pronounced among girls and women. Although vitamin C’s ability to regulate blood sugar levels is more theoretical at this point, some diabetics already use vitamin C to help treat their condition.

Getting your kids started on a gluten-free casein-free diet (GFCF) or the Feingold Diet can be difficult. After all, these diets forbid children from eating candy, cookies, pizza, and other foods they love. ADHD diets make cooking and doing the groceries difficult for parents too; gone are the days when you can just buy bags of potato chips or whip up a plate of pasta to ease your children’s hunger pangs. But you don’t have to come up with gourmet dishes to cook for ADHD kids, and implementing an ADHD diet does not mean restricting your children to bland, uninteresting food while their friends feast on tasty morsels. With the help of these ADHD cookbooks, your kids can eat delicious, nutritious meals without becoming uncontrollably hyperactive and inattentive after.

In the UnRitalin Solution, we place a lot of importance on diet and proper nutrition as a key to overcoming ADHD. Research shows that artificial additives and certain other food substances can aggravate the trademark symptoms of ADHD, including inattention and hyperactive behavior. These foods cause adverse reactions that impact the brain wave patterns in specific areas of the brain, which in turn triggers the ADHD-like symptoms.

Although very few researchers have looked into the actual mechanisms by which food allergies affect ADHD symptoms, a small study done in 1997 was able to document the phenomenon well. Researchers from Australia’s Institute for Child Health Research investigated the changes in brainwave patterns when participants with ADHD ate foods they were allergic too. The results are very telling and support the theory that an intolerance to certain foods are responsible for ADHD-like behaviors.

Before moving on to the study’s main points, it might help to have a brief discussion on how ADHD is traditionally diagnosed. Since the three hallmark symptoms of ADHD are also symptoms of other disorders, simply checking them off a list is not enough. One other widely-used diagnostic tool is called the Conner’s Rating Scale. This numerical scale is usually filled up by parents or teachers to provide an objective measure of the ADHD symptoms. The higher the numerical score, the more intense the ADHD symptom is. Using a certain cut-off point, the clinician can determine if a child qualifies for ADHD. Aside from that, the symptoms should have been present for over six months in at least two different environments. Although other professionals use different tests to make the diagnosis, the Conner’s Rating Scale plays an important role in screening ADHD from other behavioral disorders.

In the Australian study, twelve children with known mild to moderate food allergies had their brain wave activation patterns mapped by a Quantitative Electroencephalography (QEEG). You might want to read our article on the QEEG test to understand the differences in the ADHD mind’s brain wave patterns. The QEEG scan was done twice – once after five days of consuming the allergenic food, and once after two weeks of avoiding these foods. In addition, the children were made to take the Conner’s Rating Scale twice – once after eating the allergenic foods, another after the two week period of avoiding the allergenic foods.

Below is a table of the children’s Conner scores. In the version of the scale used by the study, the cut-off score for ADHD is 15.

As you can see, ten of the participants had scores above the threshold for ADHD once allergenic foods were introduced to their diets. It seems that consuming foods that provoke allergies is enough to cause ADHD-like symptoms when they weren’t there before. The researchers also noted that the most common allergenic foods among the children were wheat, milk, food colorings, and beet sugar.

Aside from that, the QEEG scans showed the changes in sixteen different brain regions after eating the allergenic foods and after avoiding the allergenic foods. To help you understand the results, below is a table of the brain wave types and activity levels.

Of all the brain waves, the researchers noted that the beta-1brainwave was most affected by the food allergies. The frequency changes were highly concentrated in the temporal and right frontal regions of the brain – the brain regions most associated with ADHD.

Although the population of the study is very small, the findings pose interesting questions as to how many cases of ADHD are actually caused by food intolerances and can be treated with the right ADHD diet. Of course, food allergies are just one potential cause of ADHD, but studies like this one lend credibility to the effectiveness of eliminating gluten, casein, and food additives from a diet.
