Adverse behavioral responses to ingestion of any kind of candy have been reported repeatedly in the lay press. Parents and teachers alike attribute excessive motor activity and other disruptive behaviors to candy consumption. However, anecdotal observations of this kind need to be tested scientifically before conclusions can be drawn, and criteria for interpreting diet behavior studies must be rigorous. Ingredients in nonchocolate candy (sugar, artificial food colors), components in chocolate… 
Life is sweet: candy consumption and longevity
TLDR
Investigation of whether candy consumption was associated with longevity found that it cannot be totally unhealthy, and since candy has existed for centuries, it was surmised that it could be totally healthy.
Dietary and Nutritional Treatments for Attention-Deficit/Hyperactivity Disorder: Current Research Support and Recommendations for Practitioners
TLDR
Clinicians can apply the SECS versus RUDE rule: treatments that are Safe, Easy, Cheap, and Sensible (SECS) require less evidence than those that are Risky, Unrealistic, Difficult, or Expensive (RUDE).
Treatment alternatives for Attention-Deficit! Hyperactivity Disorder (ADHD)
TLDR
Some alternate treatments of ADHD are effective or probably effective, but mainly for restricted etiologic subgroups, and initial evaluation should consider the relevant etiologies.

TLDR
Some alternative treatments of ADHD are effective or probably effective, but mainly for certain patients, and initial evaluation should consider the relevant etiologies.
Is Sugar Consumption Detrimental to Health? A Review of the Evidence 1995—2006
TLDR
Overall, the available evidence did not support a single quantitative sugar guideline covering all health issues, and combinations of sugar amount/frequency, fluoride exposure, and food adhesiveness were more reliable predictors of caries risk than the amount of sugar alone.
The effect of childhood malnutrition on externalizing behavior
TLDR
Different lines of evidence support the view that poor nutrition contributes to the development of child behavior problems, with an emphasis on micronutrient deficiency.
Practice guidelines and parental ADHD treatment evaluations: friends or foes?
TLDR
Examination of parental evaluations of treatment approaches to attention-deficit/hyperactivity disorder and the congruence of these evaluations with professional practice guidelines indicate that professional guidelines and parent ADHD treatment evaluations are only partially congruent.
Evaluation and treatment of ADHD.
TLDR
The recommended evaluation for ADHD-specific questionnaires can help determine whether children meet diagnostic criteria for the disorder, and psychosocial, behavioral and educational strategies that enhance specific behaviors may improve educational and social functioning in the child with ADHD.

Relative effects of drugs and diet on hyperactive behaviors: an experimental study.
TLDR
There is evidence to suggest that the behavior of three to eight children was diet-responsive, depending on the criteria used, and there is evidence, particularly in teacher ratings, in support of Feingold's hypothesis if it is modified.
Synthetic food colors and hyperactivity in children: a double-blind challenge experiment.
Nine hyperactive male subjects, selected on the basis of showing a favorable "response" to the Feingold diet in an earlier study, were maintained on a strict elimination (Feingold) diet for 11 weeks,
Effects of artificial food colorings in children with hyperactive symptoms. A critical review and results of a controlled study.
TLDR
This study studied only children who were already on the Feingold diet and who were reported by their parents to respond markedly to artificial food colorings, attempting to exclude placebo responders, and administering high dosages of coloring.
Dietary factors and hyperactivity: a failure to replicate.
TLDR
Suggestions for further research are outlined, and the need to separate hyperactive children according to whether they receive stimulant medication or not, and assess attention deficit disorders in addition to behavioral components of hyperactivity are stressed.
Effects of sugar on aggressive and inattentive behavior in children with attention deficit disorder with hyperactivity and normal children.
TLDR
Cognitive attention and aggressive behavior immediately following an acute ingestion of sugar compared with saccharin and aspartame-sweetened placebos in 17 subjects with attention deficit disorder with hyperactivity compared with 9 age-matched control subjects were assessed.
Food Additives and Hyperkinesis: A Controlled Double-Blind Experiment
TLDR
It is concluded that the K-P diet may reduce hyperkinetic symptoms, though this result is put forth with caution in view of several features inherent in the present study which need further evaluation.
Behavioral effects of caffeine in children. Relationship between dietary choice and effects of caffeine challenge.
TLDR
While receiving caffeine, low consumers were perceived by their parents as more emotional, inattentive, and restless, while high consumers were not rated as changed, suggesting a possible physiological basis in children for dietary caffeine preference.
Sugar "allergy" and children's behavior.
TLDR
Sixteen children whose behavior was said to become aggressive, overly active, loud, and noncompliant when ingesting sugar were tested, and results indicate that high doses of sugar are not related to abnormal behavior.
