Many people know that drinking soup before a meal can help with weight loss. But is it suitable for everyone? From a nutritional perspective, drinking soup before a meal can easily create a feeling of fullness. Therefore, obese individuals should drink soup before meals, which can slow down their eating speed and prevent overeating. However, patients with chronic atrophic gastritis have reduced gastric acid secretion. Drinking soup before a meal can dilute gastric juice, further affecting food digestion, so it is not advisable to drink too much soup before meals.
