The need for a good diet begins early. A study published in 2013 in the “Journal of the American Academy of Child and Adolescent Psychiatry” examined the diet of children age 6 months to 5 years old, as well as the diet of the mother while she was pregnant. Researchers concluded that the diet of both the pregnant mother and the child after birth can have an effect on mental health of the child; a diet high in unhealthy junk food and low in nutrient-dense food were linked to behavioral and emotional problems, including anxiety and depression.
