Consuming pistachios at night could potentially aid digestion.
A new study suggests that replacing a nighttime carbohydrate snack with pistachios could lead to beneficial shifts in the gut microbiome, potentially improving gut health, reducing systemic inflammation, and helping slow the progression to type 2 diabetes.
The 12-week crossover clinical study involved 51 adults diagnosed with prediabetes who alternated between eating about two ounces (57 grams) of unsalted pistachios at night and a typical carbohydrate snack. Stool samples were collected and analyzed via 16S rRNA gene sequencing to identify gut microbial changes.
The findings reveal that the overall bacterial diversity was significantly different between the two conditions. Participants who snacked on pistachios showed significant differences in their stool bacterial communities compared to the carbohydrate snack routine.
One of the key benefits of this switch is improved gut microbiome diversity and composition. The study found an increase in beneficial bacteria that produce butyrate, a compound vital for colon cell energy, maintaining gut barrier integrity, and reducing inflammation.
Moreover, levels of potentially harmful bacteria such as Blautia hydrogenotrophica (linked to toxins affecting kidney and heart health) and Eubacterium flavonifractor (which degrades antioxidants) were reduced during the pistachio phase of the study.
Potential stabilization of blood sugar and insulin levels is another critical factor in preventing or delaying the onset of type 2 diabetes. The study suggests that healthier gut microbial activity and reduced inflammation, facilitated by pistachios, could contribute to this effect.
The timing of consumption may enhance these effects, as beneficial gut bacteria are more active during rest, allowing them to utilize pistachio nutrients effectively to reshape the gut ecosystem.
While it is not implied that pistachios are a miracle cure for prediabetes, the study findings indicate that they may meaningfully shift the gut microbial landscape in adults with prediabetes. Researchers hope to explore in future research potential long-term health benefits, such as helping to slow the development of Type 2 diabetes or reducing systemic inflammation.
In conclusion, replacing a nighttime carbohydrate snack with pistachios could lead to beneficial shifts in the gut microbiome, supporting metabolic and gut health, and potentially reducing the risk of progressing to type 2 diabetes.

Science suggests that replacing a nighttime carbohydrate snack with pistachios could lead to improved health-and-wellness, particularly in individuals with medical-conditions like prediabetes. By incorporating pistachio nuts into one's fitness-and-exercise routine and focusing on nutrition, beneficial shifts in the gut microbiome could be achieved, potentially slowing the progression to type 2 diabetes and reducing systemic inflammation.
