Previous analysis has proven that prune consumption stimulates favorable adjustments to intestine microbiota and protects bone well being. These results have been largely attributed to the polyphenolic compounds in prunes, though the precise mechanisms and the contribution of different important vitamins like carbohydrates haven’t been clear.
A examine has now supplied proof that prunes are a prebiotic meals and that bone loss was reversed in mice that consumed prunes. The researchers found that polyphenols and carbohydrates in prunes behave as prebiotics and assist in restoring bone well being.
Both the polyphenols and the carbohydrate part within the prunes modified the microbiota of the intestine and have been linked to optimistic results on the well being of bone, particularly bone restoration. Prebiotics are by definition substrates that change microbiota exercise or composition and confer the advantages to the individual’s well being. In this occasion, the profit conferred was bone loss restoration.
For the examine, the carbohydrates, in addition to the polyphenol compounds, have been remoted from prunes and fed to 2 separate teams of feminine mice poor in estrogen with important bone loss for durations of 5 and 10 weeks. For comparability, 3 different teams have been fed diets that contained both complete prunes, a prune crude extract with each carbohydrate and polyphenol prune parts, or a weight loss program that contained no prunes or parts of prunes, which was the management group. Macronutrients have been equal in all diets.
In comparability to the mice who did not eat any prunes or parts of prunes, those that consumed complete prunes, prune crude extract, remoted polyphenol, or remoted carbohydrates skilled restored bone that had been previously misplaced. These mice additionally exhibited elevated manufacturing of short-chain fatty acids of their guts, in addition to favorable intestine microbiota adjustments.
Short-chain fatty acids n-butyrate and propionate will increase have been noticed particularly, that are considered handiest for the prevention of bone loss by the suppression of biomarkers linked to the breakdown of bone. These observations point out that prunes and parts of prunes might have an effect on the intestine in a method that helps to enhance immune system processes, mineral absorption, and the integrity of the intestine barrier, which might all have an effect on immune cells, metabolites, and hormones that play a component in bone well being.
It was additionally noticed that the carbohydrates might restore bone independently early within the examine whereas the polyphenol results on bone grew to become noticeable and extra important later.
According to the researchers, though they each have prebiotic exercise, there are in all probability completely different mechanisms concerned in how these prebiotics happen. They say the outcomes counsel consuming complete prunes due to the short-term advantages from the carbohydrates, and the polyphenols profit within the long-term.
They additionally talked about that the minerals, nutritional vitamins, and plant compounds in prunes may be contributing to the intestine and bone advantages.
