ABSTRACT​

Hyperestrogenism may affect 2% to 8% of men globally. Previous studies indicate that tree nut consumption is associated with sex hormones in women. Whether this is the case in men remains unknown. This study hypothesized that consumption of tree nuts was inversely associated with circulating estradiol and prevalence of hyperestrogenism in men. This cross-sectional study included 3340 men aged ≥20 years from the US National Health and Nutrition Examination Survey from 2013 to 2016. Associations of tree nut consumption with circulating estradiol and prevalence of hyperestrogenism were assessed using weighted linear regression and binary logistic regression, respectively. Among the 3340 men, 207 consumed tree nuts. The mean usual intake of tree nuts among tree nut consumers was 34.2 g/d. Amounts of usual intake of tree nuts were inversely associated with bioavailable estradiol (β = -0.032, P = .037) after adjustment for all confounders. Usual intake of tree nuts of ≥ 30 g/d (vs <30 g/d) or ≥42.52 g/d (vs <42.52 g/d) was associated with a 24% or 7% lower multivariate-adjusted risk of hyperestrogenism, respectively. Further analyses showed that usual intake of tree nuts was positively associated with circulating folate, and the latter was inversely associated with circulating estradiol. In conclusion, higher tree nut consumption was independently associated with lower circulating levels of bioavailable estradiol and a lower risk of hyperestrogenism in men. Further research is needed to verify the effectiveness of using tree nuts to treat hyperestrogenism in men.

Tree nut consumption is associated with higher sex hormone-binding globulin levels in premenopausal US women

ABSTRACT​

Low levels of sex hormone-binding globulin (SHBG) are associated with many diseases including hypertension, diabetes, and polycystic ovarian syndrome. Walnuts increased circulating SHBG in 31 women complicated with polycystic ovarian syndrome. However, whether tree nuts increase SHBG in women in a general population is unknown. It was hypothesized in this study that consumption of tree nuts was positively associated with SHBG levels in women in a general population. This cohort study included 2699 adult women from the 2013- to 2016 US National Health and Nutrition Examination Survey. Tree nut consumers were defined as those who consumed tree nuts on either of the 2 24-hours recall days. Associations of tree nut consumption with SHBG were assessed using least squares regression. Among the 2699 women, 234 were consuming tree nuts. The median SHBG concentrations were 67.1 and 59.3 nmol/L among tree nut consumers and non–consumers, respectively. Tree nut consumption was positively associated with circulating SHBG (β = 0.041, P = .018) but not testosterone nor estradiol after adjustment for all tested confounders. Sub-analyses showed that the positive association of tree nuts with SHBG presented in premenopausal women but not in postmenopausal women. Tree nut consumption remained independently associated with higher circulating levels of SHBG in premenopausal women when tree nut consumption was expressed as percentage of energy derived from tree nuts or when tree nut consumption was defined as a tree nut intake of ≥0.25 ounce per day. Future research will verify the effectiveness of using tree nuts to treat low SHBG in premenopausal women in the general population.


I'll have to get a hold of the paper and see if the SHBG correlation holds for men as with women.

Thanks Nelson for posting this paper.

Tree nuts have a lot of health benefits.

 

[Outcome]

I have a weakness for cashews and pecans. I knew about the overall health benefits of tree nuts. Good to know they can keep estrogen moderated too or at least keep hyperestrogenism in check

 

[Coconutz]

So that means guys that struggle with LOW estrogen, have to avoid tree nuts??? Jeez, what other foods can have that same effect?? Every day we learn more and more about what affects our hormones.
