The Influence of Dietary Food Moisture on Hydration Status in Adults

Description
Hydration status serves as an essential pillar of human health. Adequate hydration reduces cardiovascular strain, improves the body's ability to thermoregulate, stabilizes mood, and may reduce the risk of physiologic diseases like that of diabetes and urolithiasis.

Hydration status serves as an essential pillar of human health. Adequate hydration reduces cardiovascular strain, improves the body's ability to thermoregulate, stabilizes mood, and may reduce the risk of physiologic diseases like that of diabetes and urolithiasis. While many studies have shown the importance of adequate fluid intake on hydration status, very few have investigated the influence of dietary food moisture on hydration status. This study collected daily food diaries, daily fluid diaries, and spot urine samples over a 24hr period from 694 participants in Northwest Arkansas participating in the HYBISKUS study. Fluid and food diaries were logged in NDSR and analyzed using JMP while combined spot urine samples were analyzed using a freezing point depression osmometer to retrieve 24hr urine osmolality. Urine osmolality data was extracted from 24hr urine samples and used as the hydration status biomarker for study participants. The average contributions of water from fluids and foods in participants was 79.3 ±9.6% and 20.7 ±9.5% respectively. This study found that dietary food moisture has a significant effect on hydration status in adults with no specific macronutrient groups take precedence over any others in regard to dietary food moisture contributions. These results suggest that there are legitmate reasons to consider dietary food moisture intake when water intake recommendations are made for adults attempting to optimize health or prepare for physical exercise.
