As for eating dessert or fruit immediately after a meal, the biggest harm is that it will interrupt and hinder the digestive process in the body. Food in the stomach is perishable and decomposed into alcohol and vinegar by bacteria, resulting in stomach gas and gastrointestinal diseases.
The biggest problem of drinking soup after meals is to dilute the gastric acid needed for food digestion. Therefore, it is most taboo to drink soup while eating, or make rice with soup or drink a big bowl of soup after meals. This will easily hinder normal digestion.
The correct order of eating should be: soup, vegetables, rice, meat, dessert and fruit in half an hour.
