Autism is a disorder
of the neural development that is characterized by the disturbed social
communication and interaction. There is a repetitive and restricted behavior. Diet plays a role in autism and care should
be taken to make food choices.
According to the Center
for Disease Control and Prevention, 1 out of every 88 children has autism
spectrum disorder (ASD). This is a serious concern.
Renee Dufault et al
conducted a study to find out the influence of diet on autism. The study revealed that typical American
diet, owing to mineral deficiencies and high fructose content, may trigger
Dufault devised a new
scientific approach, "macroepigenetic" to determine the influence of dietary
factors like fructose on the body and chronic disease development.
the role of various environmental, nutritional and genetic factors in
contributing to any specific ailment.
The researchers used
the macroepigenetic approach to analyze the differences between exposure to
toxic substances and diet and their impact on development of autism between
American and Italian population.
Dufault and his fellow
workers said that the occurrence of autism in USA and Italy was not affected by
mercury exposure to fish, vaccines or dental amalgams. The study highlighted
the presence of high fructose corn syrup (HFCS) in the commonly consumed
American food (cookies, cereals, breads, crackers, etc.). HFCS creates a
deficiency of zinc which in turn interferes with the elimination of cadmium,
arsenic and mercury, thereby causing a negative impact on the neurodevelopment.
The mineral imbalances
can lead to oxidative stress in the brain. The exposure of organophosphates and
pesticides used in crop production are probably concerned with nerve damage and
The blood homocysteine
level increases with exposure to inorganic mercury and intake of high fructose
corn syrup. This adversely affects the neurodevelopment and the occurrence of
Dr. Richard Deth, the
co-author of the study and professor of pharmacology at Northern University
mentioned, "Factors like nutrition and exposure to toxic chemicals are
cumulative and synergistic in their potential to disrupt normal development."
