The Claim
In overweight and obese adults, daily intake of 54.5 mg of cranberry polyphenols for 6 weeks increases gut microbial alpha diversity specifically in obese individuals and females.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In overweight and obese adults, taking 54.5 mg of cranberry polyphenols daily for six weeks increases the diversity of gut microbes, but only in those who are obese and in females.
See the scientific wording
In overweight and obese adults, cranberry polyphenol intake (54.5 mg/day for 6 weeks) leads to increased gut microbial alpha diversity specifically in obese individuals and females, suggesting host-specific responses to dietary polyphenols.
Cranberry compounds that survive digestion feed specific gut bacteria, which change how they break down food. These bacteria produce new chemicals that help them grow and thrive, especially in people who are obese or female. This leads to more types of bacteria living in the gut.
What the research says
1 studyPeople who were obese or female had a small increase in good gut bacteria after drinking cranberry juice daily for six weeks, while others didn’t — suggesting your body type might affect how cranberries help your gut.
