“…The second hypothesis suggested that some children experience a functional reactive hypoglycemia after ingesting sugar. This hypothesis gained attention after Langseth and Dowd [1978] found that 271 hyperactive children demonstrated lower blood glucose levels than expected during glucose tolerance tests, although some have described these blood glucose patterns as normal variation in children [Josefsberg et al, 1976] and others have not observed adrenergic symptoms associated with clinical reactive hypoglycemia [Gans et al, 1990]. Wolraich and colleagues [1995] conducted a systematic review of 16 double-blind, placebo-controlled studies examining the effect of a known quantity of sugar on behavior (Table 4).…”

Use of complementary and alternative medicine (CAM) for treatment of attention-deficit hyperactivity disorder (ADHD) has become widespread in both referral and primary care populations. We review the purported mechanism of action and available evidence for selected CAM therapies for ADHD. Enduring controversies, such as elimination of artificial food additives, colors, and/or preservatives; the effect of sugar on behavior in children; and the use of EEG biofeedback, have been well studied but lack support as effective sole treatments for ADHD. The initial evidence for some emerging CAM therapies, such as essential fatty acid supplementation, yoga, massage, homeopathy, and green outdoor spaces, suggests potential benefits as part of an overall ADHD treatment plan. More rigorously designed studies are needed to evaluate their effectiveness as single therapy for ADHD.

“…It has been suggested that reactive hypoglycemia, associated with increased production of epinephrine, could produce restlessness in hyperactive children who eat sugar. Langseth and Dowd (1978) claimed that 75% of 265 hyperactive 7- to 9-year-olds showed abnormal glucose tolerance curves. The study lacked a normal control group, however, and Langseth and Dowd used norms that are at variance with other data for normal children (Josefsberg et al, 1976).…”

In this methodological review, we examine the behavioral effects of carbohydrates and tryptophan and conclude that high-carbohydrate foods do not provoke hyperactivity, contrary to popular beliefs. Unbalanced carbohydrate meals, however, often induce fatigue and can impair performance among both children and adults. Although tryptophan hastens sleep onset, dulls pain sensitivity, and may reduce aggressiveness, it is unclear whether similar effects can be obtained through carbohydrate ingestion. We provide support for the hypothesis that carbohydrates and tryptophan function similarly and like drugs that modify brain biochemistry and accompanying mood and behavior. We also examine implications for clinical populations who selectively crave carbohydrates.Despite professional skepticism, both anecdotal and empirical evidence continue to suggest that foods affect behavior. The empirical literature has now grown sufficiently to evaluate the validity of beliefs about one nutrient category, carbohydrates.Claims about the psychological effects of carbohydrates, especially sugar, are multiple. They range from the assumption that sugar enhances activity and aggression, to the premise that sugar has an energizing effect on behavior, to the assertion that sugar induces an anxious or depressed mood. Scientific evaluation and dissemination of accurate information about diet-behavior relations may lead to beneficial applications. They may also help to dispel folk wisdoms that can justify ineffective or even harmful health practices.Recent clinical research suggests that certain population subgroups selectively crave carbohydrates, usually as snack foods.Examples include some proportion of individuals with obesity

“…His hypothesis is that this may be caused by a de®ciency in peptidase activity (Hole et al, 1988). Several other nutritional and toxicological factors may play a role in the development of hyperactivity (ADD/ADHD): de®ciencies of essential nutrients (essential fatty acids, especially omega-3 fatty acids, zinc, iron, vitamins B 3 and C, vitamin B 6 in cases of low brain serotonin levels, calcium, folic acid and general malnutrition), the presence of environmental toxins and pesticides, the socalled candida syndrome (or fungal overgrowth disease) and sugar intolerance (Feingold, 1976;Langseth and Dowd, 1979;Swanson and Kinsbourne, 1980;Weiss et al, 1980;Stevens et al, 1996;Dommisse, 2000).

Prospective studies show that approximately one quarter of all hyperactive children go on to commit at least one criminal offense as juveniles (Mannuzza et al, 1989) and to abuse drugs and/or exhibit antisocial behavior as adults (Mannuzza et al, 1998).…”

The``mainstream'' evolutionary psychology model is currently under criticism from scientists of other persuasions wanting to expand the model or to make it more realistic in various ways. We argue that focusing on the environment as if it consisted only of social (or sociocultural) factors gives too limited a perspective if evolutionary approaches are to understand the behavior of modern humans. Taking the case of violence, we argue that numerous novel environmental factors of nutritional and physical-chemical origin should be considered as relevant proximate factors. The common thesis presented here is that several aspects of the biotic or abiotic environment are able to change brain chemistry, thus predisposing individuals to has greatly in¯uenced this ®eld of research. Through numerous articles, books and lectures he has made the research community as well as the public aware of how nutrition and heavy metals may in¯uence violence and criminal behavior. In Norway, biologist Ivar Mysterud (born 1938) took this message seriously as early as the 1970s. He initiated and headed the ecology and environment part of the broad, introductory course in General Biology (BIO 101) at the Department of Biology, University of Oslo, where he lectured on heavy metals, crime and violence from 1973 until 1999. Ivar Mysterud attempted (in vain) to get media attention for these topics. When the connections between lead exposure, behavior and crime became known after Bryce-Smith and Waldron's article in 1974, this and some other articles on heavy metals and human/animal behavior were sent to Dagbladet (one of the largest newspapers in Norway) and subsequently to the Minister of the Environment/Prime Minister Gro Harlem Brundtland, but to no avail.
