A follow-up to a University of Alberta study done in 2016 confirms that pregnant women who eat more fruit during pregnancy may be giving their babies' cognitive development a boost.

"Our research followed up on results from the original CHILD Cohort Study, which found that consumption in pregnant mothers influences infant measures of cognition up to one year after birth," said U of A post-doctoral researcher in psychology Claire Scavuzzo, the co-lead author of the study.

"Although the findings from the (original) study were exciting, they could not establish that , rather than other factors, caused the improvements on infant cognition."

To determine whether fruit was truly the factor influencing infant cognition, the scientists aimed to replicate the findings from the original study.

They found that infant rats born to mothers that had their diets supplemented with performed significantly better on tests of memory—consistent with the previous study.

"Our findings replicated what was found in humans and fruit flies. In a controlled, isolated way, we were able to confirm a role for prenatal fruit exposure on the cognitive development of newborns," explained Scavuzzo.

"We see this as especially valuable information for pregnant mothers, as this offers a non-pharmacological, dietary intervention to boost infant brain development."

"The idea that nutrition may also impact and cognition has only recently started to gain traction," said co-lead author Rachel Ward-Flanagan. "People want to be able give their kids the best possible start in life, and from our findings, it seems that a diet enriched with fruit is a possible way to do so."

A Ph.D. student studying under the supervision of Clayton Dickson, Ward-Flanagan embarked on the followup study with Scavuzzo in collaboration with pediatrics professors Francois Bolduc and Piushkumar Mandhane.

Dickson, Scavuzzo, Ward-Flanagan and Bolduc are part of the U of A's Neuroscience and Mental Health Institute. Bolduc and Mandhane, are both members of the Women and Children's Health Research Institute, which helped support the original study through funding provided by the Stollery Children's Hospital Foundation and supporters of the Lois Hole Hospital for Women.

The study, "Prenatal Fruit Juice Exposure Enhances Memory Consolidation in Male Post-weanling Sprague-Dawley Rats," was published in PLOS ONE.
