Dr. Victoria Boghosian, a gastroenterology specialist, said the belief that drinking water while eating dilutes stomach acid and interferes with digestion is mistaken. Water does not remain in the stomach in the same way food does; rather, it leaves much more quickly, particularly when consumed between meals. Meanwhile, the speed at which the stomach empties depends on the amount and composition of the food it contains.
The doctor explained that water may temporarily alter the acidity level inside the stomach, but it does not affect the digestive process, because the stomach regulates its own production of acid. Water also helps soften food and makes swallowing easier, so drinking it while eating is completely normal and necessary.
Regarding other drinks, such as juice and carbonated beverages, Dr. Victoria said they do not, by themselves, affect the absorption of food. However, sugary drinks add a large number of calories to the body, while carbonated drinks can cause bloating, belching and heartburn in some people. It is therefore important to choose fluids according to personal preference and not hesitate to drink water whenever needed.
In her final recommendations, the specialist warned that drinking tea, coffee and milk may reduce the absorption of iron from food and may also interfere with the absorption of some medicines. It is therefore better to take all medicines with plain water only, unless a doctor has given different instructions.
