Chronic constipation is a very common disease in children. Successful treatment of constipation can be achieved not only with medication but also with lifestyle changes, including a proper diet. Diets including fruits, fluids, and probiotics are good for constipation. Some dietary components are helpful for constipation, and some are harmful. In this study, we present diets related to constipation from the literature, and propose some perspectives regarding diets related to constipation.
- 아이들에게 변비는 흔함. 적절한 식이요법을 포함한 생활습관의 변화는 성공적인 변비치료법.
- 과일, 물, 프로바이오틱스는 변비에 효과적임.
The outcome of a disease treatment generally depends on patient or guardian cooperation, particularly in pediatric patients. In children with functional constipation, the better the patients eat, the better their bowel movements. This phenomenon is observed more frequently in young patients with a defecation diary. This study focuses on diets associated with constipation, such as the 3Fs: fluid (water, juice, and veberage, etc.), fiber, fruits, probiotics, and milk products. Fruits include bananas, persimmons, kiwifruit, plum, (prune), etc.
The amount of total fiber ingested per day includes that from dietary and functional fiber sources. Dietary fiber is nondigestible carbohydrate and lignin that are intrinsic and intact in plants. Functional fiber includes isolated, nondigestible carbohydrate that has beneficial physiological effects in humans. The recommended daily total fiber consumption for children >1 year is expressed as "age plus 5-(10) g" or "0.5 g/kg" [1,2,34,5,6
Classically, fiber is classified into water-soluble and water-insoluble fiber. Water-insoluble fiber includes cellulose, hemicellulose, methylcelluose, lignin, and synthetic fibers (calcium polycarbophil). Water-soluble fiber includes gums (fenugreek gum, guar gum, tara gum, locust bean gum, or carob gum), pectin, mucilage, psyllium, and glucomannan.
- 섬유소는 수용성 섬유소(물에 녹는 섬유소)와 불용성 섬유소(물에 녹지않는 섬유소)가 있음.
- 참고) 불용성 섬유소는 과일껍질, 고구마, 감자, 통곡물 등에 많고 포만감, 중금속배출 도움, 변비예방
수용성 섬유소는 다시마, 미역, 김 등 해조류에 많고 콜레스테롤조절, 혈당조절에 도움.
However, this classification is too theoretical to apply to actual treatment because every component of fiber exists in nature. A more complex classification for naturally occurring fiber has been proposed. According to this classification, 1) short-chain carbohydrates or fiber are oligosaccharides. 2) Long-chain carbohydrates: ① Soluble, highly fermentable non-starch polysaccharide fiber includes resistant starch, pectin, inulin, and guar gum. ② Intermediate soluble and fermentable fiber includes psyllium, ispaghula and oats. ③ Insoluble, slowly fermentable fiber includes wheat bran, lignin (flax), and fruits and vegetables. ④ Insoluble, non-fermentable fiberincludes cellulose, sterculia, and methylcellulose [778,910,1112,13,1415
For perspective, it is warranted to verify that for which children and at what point should fiber treatment for constipation begin? How should the fiber source be selected? Which constipation subtypes should be considered?
About 10 L of fluid per day, including about 2 L from the diet, are loaded into the adult gastrointestinal tract, and 8.5 L are absorbed by the small intestine. Another 1.3-1.4 L is absorbed in the colon, and 0.1-0.2 L is excreted in stool. About 5 L are loaded into the gastrointestinal tract of a small child per day. The absorptive capacity of the small bowel and colon can increase within a wide range to meet needs [1617
- 하루 10리터의 물 중 2리터는 음식으로부터 장으로 들어오고, 8.5리터는 소장에서 흡수됨.
1.3~1.4리터는 대장에서 흡수되고 0.1~0.2리터는 변으로 빠져나감.
- 어링아이의 장에는 매일 대략 5리터이 들어감. 소장과 대장의 흡수능력은 필요에 따라 증가함.
Against common sense that drinking water is helpful for constipation, many well-known studies, including the 2014 ESPGHAN and ESPGHAN paper, insist that no evidence supports the use of extra fluid intake to treat functional constipation [15Fig. 1 and and2)2) [18

Bowel movement scores for patients on polyethylene glycol 4000 (PEG 4000, Forlax; Beaufour Ipsen Pharma., Paris, France). Scores for the better fluid intake periods were significantly better than those for the worse fluid intake periods (median, 27.78; range, 21.43-30.00 vs. median, 25.13; range, 19.00-30.00; p=0.009).
Stool consistency scores for patients on polyethylene glycol 4000 (PEG 4000, Forlax; Beaufour Ipsen Pharma., Paris, France). Scores for the better fluid intake periods were significantly better than those for the worse fluid intake period (median, 20.00; range, 11.79-20.00; vs. median, 15.91; range, 11.00-25.00; p=0.002).
Fruit juices contain sorbitol, fructose, and phytochemicals as well as water. Some juices have a fiber component. Fruits juices are generally helpful for constipation, particularly in young children, whose intestinal function has not fully matured. Apple, prune, and pear juices are usually recommended for constipation.
- 과일주스는 sorbitol, fructose, 파이토케미칼과 물을 함유하고 있음.
- 과일주스는 특히 어린아이의 변비에 도움이 됨. 사과, 자두, 배 주스는 변비에 추천됨.
Lubiprostone (type-2 chloride channels) and linaclotide (cystic fibrosis transmembrane conductance regulator) are recently introduced drugs for treatment of adult constipation that act on intestinal epithelial ion channels and increase intestinal luminal water content [19,20
Probiotics are live microorganisms that confer a health benefit on the host when administered in adequate amounts. Dysbiosis of intestinal flora, high frequencies of Clostridium and Enterobacteriaceae species, which are rarely isolated in healthy children, have been reported in children with constipation [2122
Lactobacillus reuteri has a positive effect on bowel frequency in infants with functional chronic constipation but no improvements in stool consistency are observed [23B. bifidum, B. infantis, and B. longum) and Lactobacillus (L. casei, L. plantarum, and L. rhamnosus) increase bowel movement frequency, decrease fecal incontinence, and reduce abdominal pain in children 4-16 years of age; however, they have no effect on stool consistency [24Lactobacillus GG was ineffective as an adjunct to lactulose for treating constipation in children [2515Lactobacillus species?
Breast-milk-fed infants are less frequently constipated than those who are formula fed. Several mechanisms were proposed for this.
1) Large amounts of prebiotic oligosaccharides in human milk provide substrates for gut bacteria and this improves osmotic balance and stool consistency.
2) The fat composition of human milk may help create softer stools.
3) Breast milk contains non-digestible oligosaccharides, which act like dietary fiber, stimulate the growth of beneficial bacteria, and promote maturation of the gastrointestinal tract.
4) Breast milk also has the optimal whey protein composition and a low phosphorous content.
5) Increased levels of gastric inhibitory peptide, neurotensin, and vasoactive intestinal peptide are observed in formula-fed infants compared with those in breast-fed infants [2627282915
Fruits contain water, sorbitol, fructose, fiber, and phytochemicals. Fruits thought to be useful for treating constipation are pear, grape, plump, and apple with peel, which are rich in fiber. Here, some fruits available in Korea will be considered, including green kiwifruit, prune (plum), banana, and persimmon.
Green kiwifruit significantly increases defecation frequency, stool volume, softness of bowel motion, and ease of defecation in adult clinical studies. The proposed mechanisms for this are as follow: 1) Green kiwifruit contains 2-3 g of dietary fiber per 100 gm. Fiber plays a physicochemical role during constipation. 2) Actinidine, a protease enzyme in green kiwifruit, stimulates upper gastrointestinal tract motility. Possible induction of activity in the colon remains to be clarified. 3) Kissper, a peptide in green kiwifruit, has been characterized by anion selectivity and ion channeling. 4) Phytochemicals occurring naturally in the fruit may have biological significance [30
A prune is a dried plum, and these fruits are beneficial for constipation. They contain high levels of fiber (6.1 g/100 g), fructose (fructan), and sorbitol (14.7 g/100 g). Large amounts of phenolic compounds (184 mg/100 g), mainly as neochlorogenic and chlorogenic acids, may aid in the laxative effect [1231
Persimmons are not usually eaten in western countries; however, they are one of the most popular fruits in eastern Asia. Several types of persimmon are available. However, we will classify them into non-astringent varieties (sweet persimmon), which have a lower tannin acid concentration, and astringent varieties (mellowed persimmon and dried persimmon), which have a higher tannin acid concentration. Astringency of persimmons depends on the quantity of soluble tannins in the fruit flesh. As persimmons mature, soluble tannins become insoluble, which makes the fruit much less bitter. The total quantity of tannins decreases as the persimmon increases in size [32
Several types of banana are available worldwide. However, we will consider only the species of banana that is normally available in markets. Unripe bananas contain 100-250 mg tannins/100 g and have high amylase-resistant starch content. Thus, they can cause or aggravate pre-existing constipation. This property has been used in the BRAT (banana, rice, apple sauce, and toast) diet for diarrhea. As bananas ripen, the quantities of tannins and amylase-resistant starch decrease, while soluble sugars accumulate. Ripe bananas contain 3 g fiber/120 g, mostly in the form of soluble fiber. They also contain amylase-resistant starch and tannins [33
Constipation cannot be managed using medication alone. Better short- and long-term outcomes are achieved with lifestyle changes, including a proper diet. Pediatricians treating a child with constipation should pay more attention to these changes.
