Ferrándiz, in Encyclopedia of Applied Psychology, 2004. Therefore, inadequate nutrition is more common among children with ASD (Sharp et al., 2013). For example, some reports show that ASD features improve after the introduction of a gluten-free/casein-free diet, fatty acid supplementation, and/or treatment with pre/probiotics (Ng et al., 2019; Hartman and Patel, 2020). There are good reasons to believe that verbal reports of learned food aversions underestimate the actual number of such aversions. Therefore, a much more promising approach with regard to trace metal supplementation may be not to treat the individual with ASD using commonly available supplements that do not cross the BBB but to avoid maternal trace metal imbalances during pregnancy as a prevention strategy. The next time you went foraging for food and came across a berry that made you feel sick in the past, you would get hit with an overwhelming feeling of nausea and go eat something else.

Emesis, the process of vomiting a poisonous food item, costs an animal not only that specific meal, but other food items and often the ability to eat for a period of time. Characteristics of food aversions reported by humans are generally similar to those observed in laboratory studies of rats. This article discusses the definitions and mechanisms of the various types of food intolerance, as well as the clinical symptoms, diagnosis, treatment, and prevalence of food intolerances and their predisposing factors. However, it is very likely that nutritional differences, although possibly a significant modulator of the ASD phenotype, are not a causative factor for ASD.

Is there a food you just don’t like, and you can’t explain why? It is certain that far fewer reactions are due to true allergy (involving the immune system) than is commonly believed.

Many toddlers and young children can be “picky” when it comes to their dietary preferences, so the diagnosis of SFA should only be made if the food selectivity is so severe that it leads to nutritional deficiencies, oral motor or speech delays, and/or social anxiety surrounding eating, which causes interference in psychosocial functioning in older children. To summarize, taste-aversion learning and associative learning are vastly different, and there is a high likelihood that they use different neural mechanisms. The oral motor and speech delays can occur because these children are not engaging their oral muscles in chewing, as they otherwise would when eating a more varied diet. Also some people who are chronically ill, prone to motion sickness, or otherwise vulnerable to experiencing unpleasant gastrointestinal symptoms may be at a much higher risk of developing these aversions and having them limit their acceptable food choices (Bernstein, I. L. and Borson, S., 1986). This raises the question of what role this powerful and primitive learning plays in human food choice. Food aversions are a serious clinical problem, especially those developed by association with the nausea produced by chemotherapy for cancer, which may later interfere with eating many foods.

Also, as in nature, a food does not have to cause the sickness for it to become aversive. In a study, intravenous delivery of 30 mg zinc acetate for 30 min, followed by continuous delivery of 0.125 mg zinc per minute for 7 hours, raised the plasma zinc concentration approximately by 10-fold in animal studies. Since classical conditioning is more likely to generate implicit than explicit memories, most food aversion learning experiences in humans may form implicit, not explicit, memories. That’s how taste aversions work properly – you no longer want to eat the thing that made you sick. A year later, you may push away a plate of coconut-battered shrimp at a restaurant, and have no idea why you find it so repulsive.

Few studies have looked at the effects of trace metal supplementation (see Chapter 7), with some of these reporting beneficial effects. While mice vary in their ability to taste and respond to aversive stimuli, some species demonstrate an ability to form strong specific aversions.35 Poisonous marine larvae can elicit taste aversion in their predators.36 Interestingly, vampire bats, which feed on blood and would not normally encounter toxic food, do not demonstrate an ability for taste aversive learning to unpalatable food, although other bats have that ability (see the case study at the beginning of this chapter for more detail).37 For humans, eating a food and experiencing strong nausea and vomiting shortly thereafter result in an aversion to that food that often lasts for decades. Food aversions are natural survival mechanisms based on millions of years of evolution. Causes can include decreased oral intake (due to anorexia.
