Why Fizzy Drinks Quench Thirst Better than Water: A Study from Monell Center

While it's commonly believed that cold, fizzy drinks like Coca-Cola are the best quencher of thirst, a new study from the Monell Center sheds light on why certain beverages are more effective at satisfying our thirst.

Introduction to the Study

A recent study from the Monell Center aimed to understand the factors that influence thirst and hydration. To achieve this, 98 experimental subjects were deprived of food and drink for over 12 hours overnight, and then given cold, room-temperature, and warm beverages, both with and without carbonation.

Key Findings

The results of the study revealed that both low temperature and carbonation significantly reduce thirst. Specifically, participants drank less additional room-temperature water after drinking a cold or carbonated beverage. Menthol, which made the temperature of warm beverages feel colder, had a similar effect. However, acidity, astringency, and sweetness had no measurable impact on thirst.

Implications for Hydration

Contrary to popular belief, cold, fizzy drinks like plain seltzer or carbonated mineral water are the most effective at quenching thirst. In contrast, if you're dehydrated and want to drink a lot of water, room-temperature water may be more beneficial. This is because the carbonation in fizzy drinks can simply make the stomach feel fuller, rather than helping with hydration.

Wider Implications

Understanding these findings can help in promoting better hydration, especially among at-risk populations such as laborers, soldiers, and the elderly. For instance, administering cold, carbonated drinks can be a more effective way to rehydrate in these groups.

Conclusion

While the findings of this study align with existing knowledge about consumer preferences, it offers valuable insights into the mechanisms behind thirst and hydration. This information could be used to develop better strategies for addressing dehydration, whether due to physical labor, illness, or other factors.
