What is ADHD? Attention Deficit Hyperactivity Disorder (ADHD) is one of the neurological-behavioral disorders that begin in childhood. A child suffering from this condition is impulsive, with difficulty concentrating on any tasks. Although from the outside, the state may seem like just a lot of activity in a growing organism, this disorder can have dire consequences, especially in adulthood. According to research, children with ADHD are more at risk of being socially isolated and may experience learning difficulties (Pelsser et al., 2017). However, many of them additionally suffer from other diseases, such as autism. Finally, there is a high probability that the child will carry over the condition into adulthood. Therefore, there is a need to pay close attention to this problem and seek a durable solution that can make life easier for children. The Problems of Medications At the moment, there are several ways in which they mainly help people suffering from the disease. The most common and essential is the pharmacological method, which consists of various kinds of psychostimulants. Despite the method’s apparent effectiveness, many studies show the presence and manifestation of different effects when taking these drugs (Woo et al., 2014). First of all, psychostimulants suppress behavioral reactions, interfering with the natural development of self-discipline in a child. Secondly, these medications must be taken with great frequency; otherwise, their effectiveness is reduced. Thirdly, in addition to possible problems with other body systems, for example, with the skin, narcotic addiction to such drugs can develop in children. Thus, it is necessary to look for similar ways to solve this problem and use non-pharmacological approaches. For example, one such method is choosing the right diet, as studies show that many children with ADHD have low reserves of certain nutrients (Millichap & Yee, 2012). Causes of ADHD Despite many years of research, the causes of this disease are still largely unknown. There are quite a few groups of factors that can, to varying degrees, influence the formation of this condition. Among other things, it is believed that genetics and a hostile environment may cause ADHD. The last factor is a trigger that can lead to the development of a child’s genes’ reaction. According to research that dates back to the 1970s, nutrition can significantly impact human advancement and various conditions. It may be a lack of certain substances that help the development of cognitive functions. In the absence of specific micronutrients acting as neurotransmitters, serotonin production is disrupted, leading to behavioral disturbances. Therefore, the treatment of ADHD can be carried out by medication and by regulating a person’s diet. The Importance of Diet The reason for such a dramatic effect of nutrition on children is the process of human development itself. According to research, children under five years of age are much more vulnerable and susceptible to the characteristics of the food they eat (Zhou et al., 2016). This reaction is due to the active form of the human body at this stage. Therefore, if children lack certain micronutrients, they may develop developmental problems in one area or another, manifested in ADHD conditions. Improper nutrition can lead to a dis
