What late-night snacking and stress could mean for your gut health

  • New research suggests that individuals experiencing stress who also indulge in late-night snacking may significantly increase their risk of developing bowel problems.
  • A study involving over 11,000 participants found that those with high chronic stress indicators who consumed a quarter of their daily calories after 9 pm were 1.7 times more likely to experience constipation and diarrhoea.
  • Further analysis of data from over 4,000 individuals in the American Gut Project reinforced these findings, showing a 2.5 times higher propensity for bowel issues among those with high stress and late-night snacking habits.
