Should I take a prebiotic?

Like probiotics, prebiotics are a popular brand-new food additive. Should your household be consuming them? Experiments suggest that prebiotic supplements are safe. They are most likely healthful, too. Here is an introduction of the topic: What prebiotics are, where you can discover them, and why you may desire to make them a routine part of your diet.

What is a prebiotic?

Prebiotics are hard-to-digest food components that can be metabolized by probiotics, the useful microbes living in your gastrointestinal tract (Gibson and Roberfroid 1995). To date, the majority of research study has actually focused on particular oligosaccharides, in particular: fructooligossacharides (FOS) galactooligosaccharides (GOS) inulinThese are in fact carbohydrates, albeit carbs that people can’t digest. The only energy we obtain from FOS, GOS, and inulin is supplied by our gut flora.

The process supplies us with a little energy, but not much: FOS and inulin yield about 1.5 calories per gram (Niness 1999). A variety of bacteria can metabolize the nondigestible oligosaccharides. Nevertheless, two groups– the probiotic bifidobacteria and lactobacilli– appear to flourish on these prebiotics. In experiments where individuals have consumed prebiotic oligosaccharides, the composition of their gut plants altered.

coli (see listed below). Because of their enjoyable taste qualities and low-calorie status, FOS and inulin have actually been contributed to lots of food products. Inulin has a creamy, fatlike texture that makes it a great fat alternative. You’ll discover it in numerous table spreads, salad dressings, and dairy products. Oligofructose (a FOS) tastes sweet, and is about 30% as sweet as sucrose.

What about probiotics?

Probiotic supplements might be valuable for other disorders as well. As an outcome, researchers have actually reasoned that increasing amounts of lactobaccili and bifidobacteria already in the gut– by feeding them prebiotic oligosaccharides– would produce comparable advantages (Roberfroid 2000). There’s evidence from breast milk, too. Breast milk consists of oligosaccharides. These prebiotics promote the development of beneficial bifidobacteria in the gut, and may describe why breastfed babies suffer fewer infections than do formula-fed babies.

Randomized, controlled experiments on grownups have shown that prebiotics supplements increase the percentage of “great” bifidobacteria in stools (e.g., Depeint et al 2008; Kolida et al 2007). Research studies of formula-fed children have actually yielded similar results. In one randomized, double-blind research study, formula-fed newborns were given one of 2 treatments. Feedings with prebiotic-fortified child formula (0.4 g/100 ml prebiotic galacto- and long-chain fructooligosaccharides) Feedings with basic child formulaResearchers kept an eye on the children for 12 weeks.

However, the oligosaccharide-treated infants had fewer diarrhea-causing germs in their stools (Costalos et al 2008). Another, similar experiment found that babies receiving fructooligosaccharides in their formula had more bifidobacteria in their stool and less E.coli (Kapiki et al 2007). And an earlier experiment compared the stools of infants who had actually received prepared infant formula with the stools of breastfed babies (Knol et al 2005). In this case, some babies were offered formula with.8 g/100 ml GOS/FOS in a ratio of 9:1.

The outcomes have been duplicated because then (Holsher et al 2012). These are just a few examples. Not every study has actually reported statistically significant results. But the weight of the evidence seems to favor making use of prebiotics. As Gnther Boehm and Guido Moro conclude” The data clearly show that prebiotics of nonmilk origin can mimic the prebiotic effect of breast-feeding, and this has favorable effects for the postnatal advancement of the body immune system” (Boehm and Moro 2008). In addition to stimulating the growth of probiotics, oligofructose and inulin have other advantages.
