The Claim
8-prenylnaringenin, a phytoestrogen derived from hops, acts as a xenoestrogen that binds to estrogen receptors and may promote visceral adiposity through estrogenic activity.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting 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.
A compound found in hops called 8-prenylnaringenin can act like the hormone estrogen in the body. It might attach to estrogen receptors and could potentially cause fat to build up around the belly area.
See the scientific wording
Hops-derived phytoestrogens (8-prenylnaringenin) act as xenoestrogens that bind estrogen receptors and may promote visceral adiposity through estrogenic activity.
What the research says
3 studiesStudy: Disposition of hop prenylflavonoids in human breast tissue.
The study gave women hop supplements containing 8-prenylnaringenin and measured how much estrogenic activity they produced in breast tissue. They found the effect was tiny compared to the body's own estrogen, concluding these compounds are unlikely to cause estrogen-like effects in breast tissue.
The study tests the same hop compound (8-PN) but looks at bone protection, not fat accumulation. It shows 8-PN has weak effects on uterine tissue, which might suggest it wouldn't strongly promote fat storage either, but the study doesn't actually measure adiposity.
