Abstract
Purpose
Plantain (Musa paradisiaca), a staple food source for many people especially in the tropics, contains the neurotransmitter, serotonin which has analgesic and antidepressant effects. Therefore, this study aims to investigate the effects of chronic consumption of plantain diet on pain perception and social behavior in mice.
Design/methodology/approach
In the first set of experiments, three groups of mice were either fed rodent chow (control) or 50 or 100 per cent plantain diet, while in a second set of experiments, another three groups of mice were fed either rodent chow (control) or 100 per cent plantain or plantain + ritanserin (serotonin antagonist) for 30 days. Response to pain stimuli was studied by hot plate and formalin tests. Also, the ability of the mice to fluff up suitable beds to build nestle from nesting material was used as an index for social behavior. Serotonin concentration in mice brain was measured using high performance liquid chromatography.
Findings
The results showed that plantain diet-fed mice consumed less food but gained more body weight than control mice. Pain perception was significantly reduced in the plantain diet-fed mice compared to the control. Social behavior was enhanced in the plantain diet-fed mice when compared to control (p < 0.05). There was significant increase in serotonin concentration in the brains of 100 per cent diet-fed mice. Administration of serotonin blocker, ritanserin reversed the effects observed in pain and social behavior tests.
Originality/value
Chronic consumption of plantain diet increases serotonin concentration in the brain, suppresses spontaneous perception of pain and improves social behavior in mice. These actions may involve serotonergic pathway.
