ELI5: What happens to stomach acid when we drink while eating? Does it dilute?
gpt
Yes, but your stomach can absorb water pretty well so the dilution doesn't last long.  Drinking water with your food actually helps digestion because churning food with a liquid breaks it up better than without (your stomach "churns" food to a degree.  The liquid component gives more surface area for enzymes to contact it the food.

This is why liquid diets are preferred for the very very weak and sick; they are absorbed faster.
