Digestion is more complicated than a fixed timer for each food. How quickly the stomach empties depends on the meal’s portion size and its amounts of fat, protein, fiber and carbohydrates, as well as individual factors.
A mixed meal can take several hours to leave the stomach, while the entire journey through the digestive tract takes much longer.
So exact claims such as “this food digests in 30 minutes” shouldn’t be treated as universal rules. Your digestive system processes meals differently depending on what—and how much—you eat.
