Write an executive summary in the form of a blog article on the topic of "Researched Chinese medicine treatments for Tree Nut" summarising the research below in an objective and easy to understand way, and using language that can be easily understood by patients. Group the article into Chinese medicine treatments first, followed by nutrition and other treatments. Avoid using medical jargon and use a professional and caring tone of voice.

Write me a concise but easy to understand executive summary on the topic of "Chinese medicine treatments for Tree Nut" based on the following research that I will give you. Your summary should be 2 paragraphs long in Australian English spelling and include references to the studies.

A Cohort Study published in 2022 in the journal Nutrition Research found that Tree nut consumption is inversely associated with the prevalence of hyperestrogenism and circulating estradiol levels in men. This cross-sectional study utilized data from the US National Health and Nutrition Examination Survey between 2013 and 2016, and involved 3340 men aged 20 years and above. The associations of tree nut consumption with circulating estradiol - a form of the female sex hormone estrogen - and the prevalence of hyperestrogenism - a condition characterized by excess estrogen - were analyzed using weighted linear regression and binary logistic regression, respectively. Tree nut consumption was observed in 207 of the participants, with the average usual intake amounting to 34.2g per day. The study noticed an inverse relationship between the typical intake of tree nuts and levels of bioavailable estradiol, even after taking into account all confounding factors. Regular consumption of 30g/day or more of tree nuts was associated with significantly lower risk of hyperestrogenism. Furthermore, higher consumption of tree nuts was linked with higher levels of circulating folate, which was in turn inversely related to circulating estradiol. Therefore, the study concluded that increased tree nut consumption could potentially lower the risk of hyperestrogenism in men by reducing circulating estradiol levels.

A Cohort Study published in 2021 in the journal Nutrition Research found that The consumption of tree nuts is associated with increased levels of sex hormone-binding globulin in premenopausal women. In a cohort study of 2699 adult women participants from the 2013 to 2016 US National Health and Nutrition Examination Survey, the association of tree nut consumption with sex hormone-binding globulin levels was assessed. Tree nut consumers were identified as those who ate tree nuts within the two 24-hours recall days. The associations between tree nut consumption and sex hormone-binding globulin were studied using least squares regression. Results showed that among the participants, 234 women consumed tree nuts and tree nut consumption was positively associated with the levels of sex hormone-binding globulin. On further analysis, it was found that this positive association was present in premenopausal women but not in postmenopausal women. Furthermore, tree nut consumption remained independently related to higher circulating levels of sex hormone-binding globulin in premenopausal women irrespective of the percentage of energy derived from tree nuts or daily tree nut intake amount.

A Randomised Controlled Trial published in 2020 in the journal Andrology found that Incorporating tree nuts into a Western-style diet subtly modifies specific DNA methylation regions within sperm, thereby showing parts of the sperm epigenome can respond to dietary changes. The study methodology involved a post hoc analysis with a subset of the participants (healthy, non-smoking, and young) from the FERTINUTS 14-week randomized-controlled, parallel trial. The selected participants were from the pool of individuals who completed the entire dietary intervention trial. These individuals were split into two groups: the nut group, which consumed 60 grams per day of mixed nuts for 14 weeks, and the control group, who maintained their regular Western-style diet devoid of nuts. Investigation of the trial's results revealed no significant changes in overall methylation between the two groups. However, for the nut group, there were 36 genomic regions distinctly showing differential methylation between the beginning and end of the trial with a marked increase in methylation. No such changes were identified in the control group. Analysis also involved examining if nut consumption led to changes in the epigenetic age of cells, but no significant differences were discovered.
