Gibraltar's monkeys avoid junk food bellyache through clever method
The Jerusalem Post • • world
Key Points:
- Researchers observed Barbary macaques in Gibraltar increasingly eating soil, a behavior believed to help mitigate stomach upset caused by consuming tourists' junk food like chocolate, crisps, and ice cream.
- Soil-eating, or geophagy, may act similarly to antacids by alleviating gut acidity, adsorbing toxins, and potentially buffering microbiome disruption from an unnatural diet.
- The study tracked 230 macaques across eight groups and found soil consumption was more frequent in monkey groups with greater access to human food, especially during peak tourist seasons.
- This soil-eating behavior appears socially learned, as different groups favor specific soil types and younger macaques observe and mimic older individuals.
- Findings highlight primates' adaptability to environmental changes and suggest the potential to influence tourist feeding habits, though concerns remain about unintended encouragement of the behavior.
