Hacker News users discussed the study linking higher potassium intake at dinner with fewer sleep disturbances, mostly expressing skepticism. Several commenters pointed out the correlation-causation fallacy, suggesting other factors associated with healthy eating (which often includes potassium-rich foods) could be responsible for better sleep. Some questioned the study's methodology and small sample size, while others highlighted the difficulty of isolating potassium's impact from other dietary variables. A few users shared anecdotal experiences of potassium supplements aiding sleep, but overall, the consensus leaned towards cautious interpretation of the findings pending further research. Some also discussed the potential benefits of magnesium for sleep.
The Hacker News post titled "Higher potassium intake at dinner linked to fewer sleep disturbances – study" has generated several comments discussing the study and related topics.
Several commenters express skepticism about the study's methodology and the correlation vs. causation problem. One commenter points out that the study doesn't account for overall diet quality, suggesting that those consuming more potassium at dinner might be adhering to a generally healthier diet, which could be the actual driver of better sleep. They question whether simply increasing potassium intake, without considering other dietary factors, would yield the same results. Another commenter echoes this sentiment, mentioning the difficulty of isolating individual nutrients and attributing specific outcomes solely to them. They raise the possibility of confounding factors, like overall healthier lifestyle choices in the higher-potassium group, influencing the results.
The practicality and implementation of increasing potassium intake at dinner is also discussed. One commenter highlights the challenge of determining the potassium content of home-cooked meals, making it difficult to consciously control intake. Another user suggests practical ways to increase potassium intake at dinner, such as incorporating potassium-rich foods like spinach, sweet potatoes, and beans.
Some commenters share personal anecdotes related to sleep and diet. One relates their experience with magnesium supplementation improving their sleep quality, suggesting magnesium as a potential factor influencing sleep.
The discussion also touches upon the potential benefits of potassium beyond sleep improvement, with one user mentioning its role in blood pressure regulation. Another user raises a concern about the potential negative effects of excessive potassium intake for individuals with kidney issues.
Finally, several commenters critique the sensationalized reporting of nutritional studies in general, highlighting the need for critical evaluation of such studies before drawing definitive conclusions. They caution against assuming causality from correlation and advocate for further research to confirm the findings and explore the underlying mechanisms. One commenter even suggests that the study could just be noise, as with so many other nutritional studies that later turn out to be false.
