Nuts and Dried Fruits May Help Improve Intestinal Health

REUS, Spain, July 10, 2018 /PRNewswire/ --

A study recently published in The Journal of Nutrition looked at the impact of walnut consumption on intestinal health (human gastrointestinal microbiota). Results showed that walnut intake (42g/day) has an effect on human gastrointestinal microbiota by increasing beneficial bacteria, which contributes to better digestive health[1].



Almond consumption has been also associated with better gut health (42g/day). Due to their unsaturated fatty acid content, eating almonds may cause changes in the microbes present within the human gastrointestinal tract. It has been observed that "good" fats (unsaturated fatty acids) have antimicrobial properties which may help reduce microbial adhesion to the gut mucus[2].

It has also been shown that prune consumption may help to increase Bifidobacteria. This is possibly due to the dietary fiber content of prunes, along with other nutrients (sorbitol or phenolic compounds[3]).

The human gastrointestinal tract is one of the most densely populated microbial communities, with approximately 1,014 microorganisms, mainly bacteria. Microbial communities contribute to host health through various functions, including probiotic properties which may regulate the composition of the human gastrointestinal microbiota[4].
