1. Fruits
Melons (such as watermelon) require the shortest time to digest, while bananas take the longest time. If you feel hungry between meals and want to eat some fruit to resist for a while, banana is a good choice. Watermelon will quickly provide energy and raise blood sugar, which is especially not suitable for diabetics.
2. Vegetables
Melon vegetables (such as winter melon) take the shortest time, followed by solanaceous vegetables (such as tomatoes), followed by leafy vegetables (such as spinach, spinach, etc.) Cabbage) and cruciferous vegetables (such as broccoli), root vegetables (such as taro) take the longest to digest. Therefore, root vegetables can be used as staple food. People with poor digestion should eat less cruciferous vegetables such as broccoli. If they are eaten, they must be cooked until soft.
3. Cereals
Liquid or semi-liquid cereal foods (such as porridge) have a short digestion time, fermented foods without added fat (such as steamed buns, fat-free bread) ), which is also easier to digest. They have the highest digestibility in the body, reaching 98%. Therefore, for people with weak gastrointestinal conditions, porridge, steamed buns, etc. are good choices.
4. Protein
Liquid protein foods such as milk and soy milk are easier to digest, but it takes 4 hours or more to fully digest protein-rich meats such as beef and chicken. long time.
5. Fats
The digestibility of fats is related to the content of lower fatty acids and unsaturated fatty acids. The higher the content of these fatty acids, the easier it is to digest. Vegetable oils are therefore easier to digest than animal oils. Consuming fat with grains or protein foods will prolong the digestion time of the latter. Therefore, eating oily staple foods and dishes will cause a great burden on the gastrointestinal tract.
Extended information
Long-term lack of dietary fiber can easily lead to constipation, hemorrhoids, intestinal diverticula and colon tumors, as well as hyperlipidemia, atherosclerosis and Diabetes etc. Therefore, a low-residue diet is not suitable for long-term consumption.
Benefits of fiber
1. Treatment of diabetes
Dietary fiber can improve the sensitivity of insulin receptors and improve the utilization rate of insulin; dietary fiber can wrap The sugar content of food is gradually absorbed, which has the effect of balancing blood sugar after meals, thereby regulating the blood sugar level of diabetic patients and treating diabetes.
2. Prevention and treatment of coronary heart disease
Elevated serum cholesterol levels can lead to coronary heart disease. The excretion of cholesterol and bile acid is closely related to dietary fiber. Dietary fiber can combine with cholic acid, causing cholic acid to be quickly excreted from the body. At the same time, the combination of dietary fiber and cholic acid will promote the conversion of cholesterol into cholic acid, thereby reducing cholesterol levels.
3. Antihypertensive effect
Dietary fiber can absorb ions and exchange with sodium ions and potassium ions in the intestine, thereby reducing the sodium-potassium ratio in the blood, thus reducing blood pressure. The role of blood pressure.
