Think about hydration, protect your health!

Hydration has been shown to have a positive impact on health, and despite the accumulating evidence, still one out of 2 women and 2 out three men do not meet the EFSA daily adequate intake recommendations for water, according to the Liq.In7 database.

Hooton and colleagues demonstrated a beneficial effect by showing that increasing water intake by 1,2L /day reduces urinary tract infections recurrence by 50% in women with recurrent UTI. Thus, there is a consequential proportion of women who could benefit from a reduction in the number of UTI by increasing their water intake.

Hydration has been shown to have a positive effect on cognition and mood in adults and children. Khan and colleagues very recently demonstrated positive effect of increased water intake on cognitive performance in children by showing for the first time that increasing water intake to 2,5L/day during four days significantly improved cognitive flexibility compared to low water intake (0,5L/day) in children.

Moreover, in addition to kidney-related pathologies and cognitive performance, there is increasing evidence linking hydration to glycemic and hormonal responses and metabolic dysfunction.

However, establishing links between water intake, hydration and health is not enough: adopting sustainable healthy behaviors is a complex challenge.

This year at the EFAD conference, the EUHHAC session on Friday at 14h will present the latest research on water and health. This year will focus on metabolic health and behavior change.
