Nutrition and child development



Nutrition and child development
Every human being requires food for proper body functioning. However children  require better nutrition intake than the adults. Children growth and later development (cognitive, physical and psychological) is greatly determined by nutrition intake. 

Cognitive development : Cognitive  development is a term that covers human perception, thinking, and learning.  There are a number of ways in which food and dietary intake determine the future cognitive abilities in children.  Low intake of food or lack of access to proper dietary intake leads to malnutrition and in severe instances can affect the general health.  Stunting and malnutrition is known to be responsible for a lower IQ in children . However with early intervention this can be prevented in children up to 9 years. Still malnutrition is known to affect a child’s education abilities . Gibson & Green (2002) have shown that, in general, nutritional composition does show a tendency to be related to mood and cognitive differences. On an acute basis, a carbohydrate-rich but protein-poor meal can have a sedative and anxiolytic effect. Protein-rich meals may improve reaction time and be generally arousing but at the same time may increase unfocused vigilance. Again, on an acute basis fat-rich meals can lead to a decline in alertness especially where they differ from habitual fat intake. Protein-rich diets as opposed to meals have been associated with a decrease in positive and an increase in negative affect relative to carbohydrate-rich diets. In general, under nutrition results in decreased activity levels, decreased social interactions, decreased curiosity, and decreased cognitive functioning.

Physical  development  : calories are necessary for child growth. Though the calories requirements may differ , in general,  A report from 2011(NHS UK) estimated that the average energy requirements for children aged 7-10 years old a day is:
Age (years)    Boys                              Girls
7                   6900kJ /1649kcal            6400kJ /1530kcal
8                   7300kJ /1745kcal            6800kJ /1625kcal
9                   7700kJ /1840kcal            7200kJ /1721kcal
10                 8500kJ /2032kcal            8100kJ /1936kcal
However these figures are a guide because a child may need more or less depending on the environment and other factors. But limiting intake of fatty foods or fast foods and promoting foods that include fruits, vegetables, whole grains, dairy and lean protein may suffice. Protein aids child body growth and development of strong muscles. Such foods include beef, chicken, fish, beans, milk and nuts are good sources.
On the other hand , failure to meet the dietary body requirements or poor dietary intake has its own side effects in children. A diet too high in fat and calories can lead to obesity, which interferes with physical fitness, but also raises the risk of heart disease, diabetes and cancer. A diet lacking in proper nutrition can also result in stunted growth and bone disorders. Lack of a nutritious diet also effects energy for physical pursuits. Poorly nourished children have more problems fighting infections.  They are sick most of the time and this leads to school absenteeism and failure to cope with school demands. Bone is a living tissue that grows and changes constantly. During childhood, bone grows at a higher rate and it peaks to maximum density by the end of adolescence and early adulthood. Calcium is a necessity for the growth of strong bones in childhood and maintaining healthy bones throughout life.

Mental / psychological health : mental health is defined as "serious changes in the ways children handle their emotions, learn, or behave."(CDC) “we are what we eat” hence the inability to provide nutritious  food to children leads to poor mental health  . The first normative 2 years of a child area  make or break because it is when physical and brain growth is most active hence interference of that growth has dire consequences to the future mental health of a child . It is important to note that brain growth begins before birth—with the nutrition of the mother. Under nutrition and the resulting negative effects on brain  development during pregnancy and the first two years of life may be permanent and irreversible.  Most children vulnerable to this are : children separated from caregivers,  children whose caregiver has a physical or mental disability,  children whose caregiver is alcohol or drug ,dependent  children who are unaccompanied ,  children living in custodial care arrangements (e.g., orphanages).

The brain consumes a greater amount of energy than the rest of the body. That is why a child who hasn’t had a meal will be restless, irritable and in the long run this results in associated disorders like ADHD, stress , effective disorder Mood disorders etc. . A new study published in the Lancet and reported on Civil Eats, confirms that a proper dietary intake makes a difference in our lives. The study's lead author Dr. Lidy Pelsser of the ADHD Research Centre in the Netherlands confirms that "Food is the main cause of ADHD." The study found that in 64 percent of children in the US with ADHD, the symptoms were caused by food. "It's a hypersensitivity reaction to food.
In cases of emergencies where access to food is critical , it’s essential to provide and maintain at least a mean daily per capita intake of 2100Kcal and 46g of protein is recommended (UNICEF/UNHCR/WFP/WHO,2004) with rations that cover the essential micro nutrients

 Food and the right dietary intake have direct consequences on a child’s growth. In cases of emergencies or in cases of poor families who are unable to maintain a stable supply of food, it’s essential to at least to provide high quality food at any given time of feeding.  In most cases , women don’t give greater attention to breast feeding but it’s the source of the main nutrients necessary for child growth , thought mothers stable health plays a bigger role. 

Before writing this article, I was inspired by the video clip I watched on Facebook about a Syrian boy who has to wait for a doughnut to fall from a vendor, eats half and keeps another for the sibling at home.  https://www.facebook.com/video.php?v=614103635375892&set=vb.100003287823803&type=2&theater
