Q: Is it true that drinking water with your meal dilutes stomach acid therefore hindering digestion?
Drinking water by itself can dilute stomach acid to pH>4 for a short period of 3 minutes, in which after it returns to the normal stomach pH of 1.5-3.5. On the contrary, water actually aids digestion by dissolving soluble fibres to feel fuller for longer and is absorbed by insoluble fibres to prevent constipation.
Tip? Have 8-10 cups of water a day to reach the fluid recommendations of 2.1L for women and 2.6L for men. Having water before and during meals can also make you feel full so you consume less kilojoules for that meal. Keep your body happily hydrated :D
