Introduction: Liquid protein foods like milk and soy milk are relatively easy to digest, whereas it takes 4 hours or longer to fully digest protein-rich meats such as beef and chicken.
The digestion time for vegetables is 45 minutes to 2 hours.
Gourd vegetables (such as winter melon) take the shortest time to digest, followed by solanaceous vegetables (such as tomatoes and eggplants), then leafy vegetables (such as spinach and bok choy), and cruciferous vegetables (such as broccoli). The longest digestion time is for root and stem vegetables (such as sweet potatoes and taro).
The digestion time for grain foods is between 1 hour 30 minutes and 3 hours.
Liquid or semi-liquid grain foods (like congee) have a shorter digestion time. Fermented foods without added fat (such as steamed buns and fat-free bread) are also relatively easy to digest.
The digestion time for protein foods is 1 hour 30 minutes to 4 hours.
Liquid protein foods like milk and soy milk are relatively easy to digest, whereas it takes 4 hours or longer to fully digest protein-rich meats such as beef and chicken.
Fat foods have the longest digestion time, requiring 2 to 4 hours.
However, we rarely consume fat alone; it is usually ingested together with vegetables or grains.
If fat is consumed together with grains or protein foods, it will extend its digestion time. Therefore, foods like cake, which contain large amounts of fat, protein, and carbohydrates, place a significant burden on the digestive system and require 3 to 4 hours to be fully digested.
