“…However, the findings of this study converge with the rodent literature in this regard. Hsu et al [27] reported that the consumption of sucrose and high-fructose corn syrup were both associated with impaired hippocampal-dependent spatial learning and memory in adolescent rats, and additional studies have observed deficits in hippocampal-dependent learning and memory following consumption of a Western diet (characterized in part by large amounts of added sugar) [3,5,54]. Strikingly, Noble et al…”

Creativity depends on the ability to combine existing mental representations in new ways and depends, in part, on the hippocampus. Hippocampal function is, in turn, affected by a number of health factors, including aerobic fitness, excess adiposity, and diet. Specifically, in rodent studies, diets high in saturated fatty acids and sugar -hallmarks of a western diet-have been shown to negatively impact hippocampal function and thereby impair performance on cognitive tasks that require the hippocampus. Yet relatively few studies have examined the relationship between diet and hippocampal-dependent cognition in children. The current study therefore sought to explore the relationship of several diet quality markers including dietary lipids (saturated fatty acids and omega-3 fatty acids), simple carbohydrates (added sugars), and dietary fiber with creativity in preadolescent children. Participants (N = 57; mean age = 9.1 years) completed the Verbal Form of the Torrance Test of Creative Thinking (TTCT), a standardized test of creativity known to require the hippocampus. Additionally, participants completed a 3-day food intake record with the assistance of a parent, underwent dual energy x-ray absorptiometry (DXA) to assess central adiposity, and VO 2 max testing to assess aerobic fitness. Added sugar intake was negatively associated, and dietary fiber was positively associated with overall TTCT performance. These
