Do vitamins and supplements help children to pay attention in class? Is there any evidence for protein being a brain food? Do red dyes and other additives cause Attention Deficit Hyperactivity Disorder? How important is a good breakfast, really?

These are many of the questions that are part of the controversy surrounding diet, attention, and learning. While there does not appear to be a consensus on these and many other issues, there are some common-sense approaches that parents can take with their children. We will provide you with some guidance so that you can make informed decisions about these matters.

First, many parents ask their pediatricians, child psychologists, and other clinicians whether their child’s Learning Disability, Attention Deficit Hyperactivity Disorder, or other behavioral difficulty is a direct result of the child’s diet and nutrition. The simple answer is no. The vast majority of our studies indicate that these types of disorders are not caused simply by diet. While there are some exceptions with a particular food or a chemical in food causing acute distress or learning/behavioral changes, such as peanut, shellfish, and strawberry allergies; or the negative side effects that monosodium glutamate (MSG) is presumed to have on developing brains, diet does not appear to be the primary cause of learning/behavioral difficulties in the vast majority of children.

However, what complicates the answer to this question is that, of course, what you ingest has an impact on your behavior, attention, and learning. We ask parents to consider their emotional or cognitive experiences the last time they had too much, or too little, coffee to drink; if they’ve ever had an extra glass of wine that made them uncomfortable; or even a sense of physical and mental sluggishness after having too much to eat at any one time. The impact of food and diet on our emotional, behavioral, and attention processes is there for all of us to see. This is also consistent with the observations of many parents after their children have consumed a large quantity of sweets (think about the last birthday party your child went to) and then began to engage in out-of-control or atypical behavior.

Our advice on this matter is simple: pay attention to what your child eats and see what works best for him/her. The same rules may not hold true for each child, just as some adults may become jittery after one cup of coffee and others are finishing their tenth cup just prior to falling asleep at night. Use the thoughtful and structured attention that you pay to your child’s diet as a model for helping the youngster with structured activities such as doing homework, being organized, and making good decisions. Recognize that this is only one factor among many that will help to improve your child’s attention, learning, and emotional regulation

The following sections include descriptions of some of the latest research that supports the use of dietary supplements to improve attention, learning, and memory. Much of the research data is preliminary and we do not specifically endorse any of the following strategies, but want to help parents to inform themselves. We also provide links so that you can explore additional studies and reports.

Well-Balanced Diet

We have all heard the popular advisory of the importance of a good breakfast. Whether the recommendation came from a grandmother whipping up a special batch of pancakes, a parent slipping an apple into a child’s backpack as he dashes out the door, or a teacher recommending a good meal before tomorrow’s geometry quiz, the advice remains the same. A good breakfast can have a significant impact on academic performance and one’s ability to pay attention, learn, and retain knowledge. The adage that “breakfast is the most important meal of the day” may be true as well, as it refuels the body after a night of fasting and sets the tone for the day. Yet the importance of nutritious breakfasts can similarly be translated to other meals. But what defines a good breakfast or meal, you may ask.

Leading experts generally agree that it is important to maintain a balance of lean proteins and complex carbohydrates (the kind that fuel your body but do not excite it), as these can improve the operation of neurotransmitters in the brain. Proteins provide amino acids which become neurotransmitters, while good carbohydrates (such as grains, vegetables, and fruits) send these neurotransmitters to the brain. Too many carbohydrates and too little protein can cause your child’s blood sugar to spike and then plummet, causing your child to be overexcited and then lethargic or inattentive. Along with maintaining a good carbohydrate and protein balance, it is also important to avoid foods that are high in sugar as these can have adverse effects on learning, and to eat plenty of fiber (found in whole grains), which can also prevent blood sugar levels from rising and falling. The maintenance of blood sugar levels is particularly important for children with ADD and ADHD. For a well-balanced and brain-boosting diet it is also important to consume the right kind of fats, such as Omega-3 fatty acids, found in such sources as fish, vegetable oils, or as a supplement.

Although a child’s diet is not generally the cause of learning, attention or behavioral difficulties, proper food and supplement consumption can be a helpful and effective way of regulating these disabilities. Multivitamins and minerals can be a helpful way of attaining the those found in the above food sources, and are particularly beneficial with picky-eaters and when diets are deficient in these vitamins and minerals.

Foods & Supplements to Consider – Proteins – Complex Carbohydrates – Omega-3 Fatty Acids – Whole Grains – Oats – Multivitamins – Minerals (Magnesium, Zinc, Iron)

Foods & Supplements to Avoid – Sugary snacks – Simple Carbohydrates – Preservatives – Allergy-causing foods – Artificial dyes

Omega-3

Recent studies have found that omega-3s can have beneficial effects one anyone’s mental focus, but in particular on that of children with ADHD. Tests have noted that ADHD symptoms decreased in children who took fish oil daily, and that ADD children often demonstrated low blood levels of omega-3. Omega -3 fatty acids are prominent in the brain and are believed to be important in cognitive, behavioral, and brain and nerve cell function.

 

 

Sources of Omega-3

• Fatty Fish (e.g. salmon, tuna, herring, sardines)
• Vegetable & Nut Oils
• Omega-3 Supplements (e.g. fish oil)

Protein

As we have noted, proteins provide the amino acids that become neurotransmitters (which carry signals from one brain cell to another.) Proteins can also deter spikes in blood sugar levels. Remember, in order for proteins to stimulate the brain, they need to be balanced properly with complex carbohydrates. Some researchers have described protein as “brain food” and suggest that a glass of milk and a protein bar can enhance the effectiveness of studying.

Sources of Protein

• Nuts
• Soy
• Lean beef
• Fish
• Pork
• Poultry
• Dairy Product
• Eggs
• Beans
• Protein Bars or Shakes

Magnesium

How many times have you walked into a room only to realize that you cannot remember why you went in there? How often has your child forgotten an assignment or failed to be able to recall vital information during a History exam? Recent research is suggesting that memory lapses may be partially caused by a magnesium deficiency in the body, and that increasing magnesium intake can help to lessen these memory lapses. Research is also exploring the benefits of using magnesium with individuals with extreme memory impairments, such as Alzheimer’s disease. Magnesium maintains the plasticity (or the ability to change, remember, and learn) of synapses in the brain. Thus a deficiency of magnesium would decrease this plasticity and would inhibit learning and memory. It is believed that the majority of Americans are not receiving enough magnesium in their diets. Magnesium is essential to hundreds of biochemical reactions in the body, and it is also active in making the neurotransmitters involved in concentration and attention (particularly beneficial for children with ADHD.) The benefits of magnesium are numerous and the mineral would make a great addition to yours and your child’s diet.

Sources of Magnesium

• Nuts
• Soybeans
• Dark leafy vegetables (e.g. spinach)
• Meats

Zinc & Iron

If your child experiences rollercoaster-like highs and lows in mood, or suffers from ADHD, symptoms may be worsened by a deficiency in the minerals zinc or iron. Zinc and iron regulate the production of dopamine (a neurotransmitter that controls mood.) Research has linked low serum zinc levels to depression, and suggests that iron deficiencies can have a significant, negative impact on the symptoms of children with ADHD. Like Magnesium, zinc and iron are also essential for hundreds of other activities and functions in the body. Consider adding or boosting your zinc and iron intake to improve bodily health, and to level out roller-coaster moods. Diet is the safest way to increase zinc and iron levels but a multivitamin can also be effective.

Sources of Zinc – Red Meats (e.g. Beef, Pork, Lamb) – Poultry (e.g. Chicken, Turkey) – Beans – Nuts – Soy – Seafood (e.g. oysters) – Fortified Cereals

Sources of Iron – Red Meat – Organ Meats (e.g. liver) – Beans – Nuts – Soy – Seafood (e.g. clams) – Fortified Cereals

Green Tea

The miraculous effects of green tea and green tea extract are often advertised. The sweet-smelling beverage has been said to boost metabolism and support weight loss, among various other claims. While many of these have not been substantiated, researchers are beginning to recognize the benefits that green tea may have in improving memory function. It is also believed that it may deter Alzheimer’s disease by preventing the development of certain enzymes believed to be important in its development. If you consider the best part of waking up to be Folgers in your cup, consider a cup of sweet-smelling and memory-retaining green tea.

Be aware that caffeine may have adverse affects on children with high energy levels
