There are many myths surrounding drinking water during meals, with some claiming it can dilute digestive enzymes, worsen GERD, and make digestion more difficult. However, a registered dietitian explains that for most people, drinking water with meals can actually support digestion by helping to break down food, dissolve nutrients, and move food through the digestive system. Certain medical conditions like bariatric surgery or chronic kidney disease may require restricting liquid intake during meals, but for the general population, there is no evidence that drinking water with meals is harmful.

Why it matters

Proper hydration has many health benefits, from skin health to joint function. Understanding the role of water intake during meals can help people maximize the benefits of drinking water while avoiding potential pitfalls for those with specific medical needs.

The details

Drinking water during meals can help break down food, dissolve nutrients, and move food through the digestive system, making it easier to chew, swallow, and digest. Contrary to some myths, water does not dilute stomach acid or interfere with nutrient absorption. In fact, it can support more effective nutrient absorption as food moves through the digestive tract. Drinking water with meals may also help with weight management by promoting feelings of fullness. However, certain medical conditions like bariatric surgery or chronic kidney disease may require restricting liquid intake during meals to avoid discomfort or other complications.

  • Drinking water 30 minutes before and after meals is recommended for those who have undergone bariatric surgery.
