Brain Health

Brain Health is used to describe how well a brain is functioning, and it is also used as synonym for mental health. Whether or not a brain is healthy is mainly measured through behavior, which can be the ability to cope with normal life situations, and also performance on computerized tasks. Scans such as Magnetic Resonance Imaging (MRI) or electroencephalography (EEG) can sometimes be used to investigate brain health, but only in specific situations such as to identify epilepsy, brain tumors or large-scale loss of neurons.


Elimination Diet

An elimination diet can be useful for seeing if psychological symptoms are reduced.  It involves a temporary (5 weeks) total change of diet in which the patient is only allowed to eat a few different hypo-allergenic foods (e.g. rice, turkey, lettuce and pears). After a significant reduction of ADHD symptoms, a 12-month reintroduction phase is needed to find out which products trigger ADHD symptoms.



Exercise (e.g., running, or cycling) is a subcategory of physical activity that describes any physical movement of the skeletal muscles in a planned and structured way to improve physical fitness or getting a health benefit.

Mediterranean Diet

The Mediterranean Diet is based on the traditional cuisine of countries bordering the Mediterranean Sea. It is typically high in vegetables, fruits, whole grains, beans, nuts and seeds, and olive oil. The main components of the Diet include a daily consumption of vegetables, fruits, whole grains, and healthy fats; a weekly intake of fish, poultry, beans and eggs, and moderate portions of dairy products. The intake of red meat should be limited.

Mental Health

Mental health is the level of psychological well-being or an absence of mental illness. According to the World Health Organization (WHO), mental health is an individual’s sense of well-being, the ability to recognize, express and modulate one’s own emotions, as well as empathize with others. Mental health is also the ability to cope with adverse life events and function in social roles.


The microbiome is the collection of microbes from bacteria, fungi, protozoa and viruses that live on and in our body which perform symbiotic functions to maintain and also reflect our state of health, both physically and mentally.  The microbiome can weigh as much as our brain, and produces a wide variety of chemicals that our body cannot produce by itself.  Our largest microbiome exists in our large intestine, and helps to process food and liquid intake to create optimal bodily function. 


Probiotics:  Are defined as live microorganisms that, when administered in adequate amounts, confer a health benefit. Fermented foods such as yoghurt, sauerkraut, kombucha, tempeh, kimchi are probiotics.  Although both probiotics and prebiotics sound similar, they shouldn’t be confused as they work in different ways in the gut.  


Schizophrenia is a severe and chronic mental disorder. It is characterized by disturbance in thought, perception and behavior. The symptoms have a negative impact on most functions and social interactions of the individual suffering from it. Schizophrenia does not imply a “split personality” or dissociative identity disorder, as is often wrongly labelled in the public.



What is stress? Stress is the response of your body to cope with changes in your surroundings. It is normal and necessary to be able to adapt to these changes. However, if the so-called stress response is too long or not helpful for the situation, it becomes a bad thing.



Supplements are pills, capsules, tablets or liquids containing nutrients. They can contain, for instance, (multi)vitamins, minerals or fish oils. As their name suggests, dietary supplements are intended to supplement the diet. People may take supplements when their diet does not provide all the nutrients they need. Dietary supplements are not drugs. They are not intended to treat, prevent or cure diseases.
