Pistachios are highly beneficial for gut health, packed with fiber, polyphenols and proteins that nourish gut microbes.
A U.S. study indicated that consuming pistachios at night can positively affect gut bacteria and reshape the gut microbiome, particularly in adults with pre-diabetes.
Pistachios act as prebiotics, feeding beneficial gut bacteria like Bifidobacteria and Lactobacillus, which produce short-chain fatty acids that reduce inflammation and support a healthy gut lining.
These nuts also contain compounds such as polyphenols, tocopherols and lutein, which are metabolized by gut microbes and help modulate the gut's microbial composition.
Choosing pistachios over high-sugar or high-salt snacks like biscuits or chips can further enhance gut health by avoiding disruptive additives.
