There's no concern that water will dilute the digestive juices or interfere with digestion. In fact, drinking water during or after a meal actually aids digestion. Water and other liquids help break down food so that your body can absorb the nutrients. Water also softens stools, which helps prevent constipation.
Looking for other ways to promote good digestion? Focus on a healthy lifestyle. Eat plenty of fruits, vegetables and whole grains. Maintain a healthy weight. Include physical activity in your daily routine.
