Prune Juice & Constipation


HOW PRUNE JUICE WORKS

prunes


1) Sorbitol


A sugar alcohol found in prunes, apples, pears and peaches. Prune juice has relatively high levels of sorbitol. Sorbitol is Sunsweet's favourite selling point, sorbitol is prebiotics, hard-to-digest sorbitol holds up water in the intestines.


Sorbitol is most popular as the sweetener in "sugar-free" chewing gums.


Over zealous gum chewing can therefore cause diarrhea and stomach pain. That's how a 21 year old woman lost 11 kilos in eight months. She must have been relieved when her doctor traced the mysterious weight loss to her gum chewing habit, thankfully not cancer. Of course, she didn't notice tiny prints on the chewing gum packet about the laxative property of sorbitol. That was what I read from BBC, on how people unknowingly soften their stools by enjoying chewing gums.


2) Dihydrophenylisatin/ dihydroxyphenyl satin


The natural laxative in prunes which stimulates muscle contractions, a chemical relative of over the counter laxative biscodyl.


A combination of sorbitol and dihydrophenylisatin makes prune a better constipation relief than psyllium husk which has ten times more dietary fiber. In a research supported by the California Dried Plum Board, prune increases average weekly bowel movements from 1.8 to 3.5 defeating psyllium husk , which increases bowel movements from 1.6 to 2.8.


FIBER

As a dried fruit, prunes are considered as high fiber food. However, prune juice which is basically soaking/heating/blending soften prunes has very little fiber. The nutritional value of various forms of prunes compared with the juice and puree is based on nutritiondata.self.com

DOWN SIDE


Unable to digest sorbitol well, the body leaves it for the gas-producing bacteria in the large intestine. This makes prune juice a "gas producer ".


In a study conducted in Finland, 54 volunteers reported fewer days in defecation on days they consumed prune juice, which consisted of plum juice concentrate, prune puree, water, and fructose, 125ml twice a day. However...this "pruney" cocktail also increased flatulence.


Not forgetting also the high calories.


Appropriate Age


When can a baby be introduced to prune juice as a constipation relief? Generally pediatricians give a range between two months to six months. However, the state government of Victoria advised against giving prune juice to babies under nine months of age even when diluted due to a "natural bowel irritant" which is not suitable for very little ones.
