Summary
Yogurt consumption increased susceptibility to motion sickness in human volunteers during Coriolis stimulation. However, the electrogastrogram (EGG) patterns associated with motion sickness remained unchanged regardless of dietary state.
Area of Science:
- Neuroscience
- Human Physiology
- Gastroenterology
Background:
- Motion sickness is a common condition affecting human well-being.
- Dietary factors may influence susceptibility to motion sickness.
- Electrogastrogram (EGG) measures gastric electrical activity, potentially linked to nausea.
Purpose of the Study:
- To investigate the effect of yogurt ingestion on motion sickness susceptibility.
- To examine the relationship between diet, motion sickness, and electrogastrogram (EGG) patterns.
Main Methods:
- Seven human volunteers underwent Coriolis stimulation (rotating chair).
- Testing occurred in both fasted and post-yogurt (6 oz) ingestion states.
- Surface electrogastrogram (EGG) recordings were taken until the Malaise-III (M-III) endpoint.
Main Results:
- Subjects consuming yogurt reached the M-III endpoint with significantly fewer head movements (p<0.01).
- Yogurt ingestion enhanced motion sickness susceptibility.
- EGG recordings at M-III showed similar patterns (tachygastria followed by low amplitude waves) in both dietary states.
Conclusions:
- Yogurt consumption increases susceptibility to motion sickness.
- Dietary intake, specifically yogurt, does not alter the electrogastrogram (EGG) pattern associated with motion sickness.
