Poor Diet & Aggressive Behavior in Children

Early Childhood

A 2004 study at the University of Southern California (USC) found a strong link between infant and toddler malnutrition and antisocial behavior in childhood through adolescents. In other words, a very poor diet during the first few years of life causes aggression later, in children and teens. This study followed children who, at the age of three, had physical symptoms of either protein deficiency, vitamin B deficiency, anemia or zinc and iron deficiency.


The above-referenced study at USC uncovered a link between lack of good nutrition in the first three years and lower IQ. Adrian Raine, a co-author of the study, points out that zinc, iron, protein and vitamin B are all necessary for brain development. While lower IQ does not intrinsically cause aggressive behavior, poor nutrition early in life causes brain deficiencies that result in both lower IQ and aggressive behavior. The three are strongly correlated.

Attention Deficit Hyperactivity Disorder

Attention Deficit Hyperactivity Disorder (ADHD) does not intrinsically cause aggression, but the behaviors of ADHD children often create a dynamic of frustration between child and caregiver or teacher. The mutual frustration may elicit aggression in the child. At the University of Maryland Medical Center, experts discuss diet as a treatment for ADHD. Some parents have found eliminating sugars, artificial sweeteners and artificial colors from children's diets helpful. Feeding the child a diet high in protein and complex carbohydrates may eliminate some of the ADHD behaviors.

Prevent Aggressive Behavior With Fruits and Vegetables

The Harvard School of Public Health has conducted various studies about children's diets and what factors go into children eating more fruits and vegetables. Fruits and vegetables are good ways to get the vitamins and minerals that help prevent aggressive behavior into your child's diet. They found that two simple things encourage healthier eating in childhood: stocking the refrigerator at home with healthy snacks, such as fruits and vegetables, and eating dinner together as a family. During family dinner, parents serve, eat, and expect children to eat produce.

Cut the ends off the vegetables and fruits, and peel the skins off with a vegetable peeler. Remove seeds and cores with the knife, then chop the fruits and vegetables into small 1/2-inch cubes. The skins and seeds will not puree and can be a choking hazard, especially for babies.

Place the fruit and vegetable cubes into a pot, and add just enough water to cover the bottom of the pot. Too much water in the pot removes important vitamins and nutrients. Cover the pot with a lid, and cook the fruits and vegetables until they are tender when you poke them with a fork.

Use a colander to drain the water from your cooked vegetables.

Remove the pot from the stove top, and place on a hot pad. Pour the vegetables through a colander to remove the liquid, then leave them to sit in the colander for a few minutes to cool.

Pour the cooked fruits or vegetables into a blender and puree. Rub a bit of the pureed food between two fingers to make sure it has a thin consistency. If the consistency is too thick, add 1 tsp. water and puree again, repeating until the desired consistency is achieved.

Store pureed fruits and vegetables for a few days in the refrigerator, or keep them in the freezer for up to six months. Use plastic containers for the refrigerator and freezer bags for the freezer.
