Cognitive benefits from a sweet potato meal may be overstated according to a study published today in the journal JAMA Network Open led by Christina Reiman Ph. D. of the Department of Nutrition Sciences Imperial College London.
According to the study participants who ate the sweet potato meal were found to have higher working memory than those who did not consume the meal mirroring previous research that found participants thinking and memory invigorating brain function was influenced by appetite.
This study which shows a clear benefit from the consumption of a small amount of sweet potato in healthy adults is highly encouraging stated Dr. Reiman the lead author and a postdoctoral fellow in the Department of Nutrition Sciences Imperial College London.
Based on the studys findings its a good idea to chew up a handful of the sweet potato to be sedentary and continue to reap the benefits when self-reported feeling envious.
Cognitive Benefits of Sweet PotatoesTodays study offers a new learning resource for those interested in sweet potato consumption. This new research-led by COURIOUS investigator pub health professor Christina Reiman (DNM no. 41138) shows that produced a significant effect on the effects of the main food on brain functioning in healthy adults.
In this case the effects reported were found to be sustained at 12 weeks.
Similar to past studies participants had to consume their equivalent of a highly active week of chocolate which is a good level of chocolate consumption.
On the morning of the day study participants ate the chocolate regularly but not for 30 minutes the previous seven days and were asked to either report a feeling high or very satisfied using a touch screen. Thereafter participants were tested to see which or both their performance and mood were unaffected by eating chocolate.
What the study did.
Following an eight week stress control period participants randomized into one of the two groups completed a series of tests to assess mood and cognition. The researchers tested mood working memory concentration impulsivity and emotional empathy assessed in both well-fed and unwell fed groups.
Participants were actually tested using 15 convenient laboratory reactions and were presented three days prior to a dose of the sweet potato meal.
The data were then collected in an online link for statistical analysis.
The results produced a comprehensive view of both brain function before and after the consumption of the sweet potato meal.
As it was found to be poorer than in the placebo group the effects of the sweet potato fruit were found to be:
This study was undertaken as part of the World Sugars for Healthy Kids dietary intervention.
This work is an important step in researching what sweet potatoes actually do to the brain due to previous studies. The sweetness of the sweet potato is the factor that differs from the sweetness of a regular potato and we need to desensitize our brains to random effects so that we have better outcomes noted Dr. Reiman.
Its important that anyone who has had a troubling experience with consuming sweet potato should be mindful of this finding as it challenges assumptions and perceptions about the benefits of consuming sweet potatoes she said.
Also the studys authors admit they cannot prove that eating sweet potatoes causes improvements. In future research they will investigate whether healthy adults have a similar improvement for brain function that follows consumption.
