MORE Testosterone & LESS Estrogen (WITH THIS VEGAN DRINK!)


I want to start by saying that I hate the word “superfood”, but I won’t deny that it’s an attention-grabbing buzzword, so there’s that. And I do want people to watch my videos. I mean, after all, I don’t make them to collect the proverbial dust!

Anyhow, I got an interesting paper to share with you all this week, that was published this past March in The American Journal of Clinical Nutrition.

Researchers from Harvard University examined the data of 22,948 people extracted from two different cohort studies. The participant breakdown was 15,551 women, all taken from the Nurses’ Health Study, and 7,397 men, all taken from the Health Professionals Follow-Up Study. Researchers investigated the effects of caffeinated, decaffeinated, and total coffee consumption on 14 different plasma biomarkers, including but not limited to IGF-1, total and free estrogen, total and free testosterone, SHBG, and IL-6. Based on initial blood-drawings, all participants had tested free of diabetes, cardiovascular disease, and cancer. Furthermore, all participant data was adjusted for demographic, clinical, and lifestyle factors which included sex, age, race, fasting status, BMI, physical activity, alcohol consumption, smoking status, calorie intake, caffeine intake, multivitamin use, painkiller use, hypertension, cholesterol levels, whether or not they used any sort of hormone therapy, and lastly, menopausal status in the case of female participants.

What the researchers discovered was that coffee consumption is associated with favorable profiles of numerous biomarkers in key metabolic and inflammatory pathways. And these results were dose-dependent. For instance, at 2-3 cups of coffee per day, total and free estrogen decreased by 2.1 and 2.6 picograms per millilitre respectively. Whereas total and free testosterone increased in women by 6.5 and 8 nanograms per millilitre respectively, and in men by 1.9 and 0.7 nanograms per millilitre respectively. But, at 4 or MORE cups per day, total and free estrogen decreased by 5.7 and 8.1 picograms per millilitre respectively. And total and free testosterone increased in women by 9.3 and 7.3 nanograms per millilitre respectively, and in men by 5.3 and 3.6 nanograms per millilitre respectively.

Moreover, these results remained consistent whether or not the coffee included caffeine. Thus, the researchers theorize that this may be the work of the polyphenols in coffee, such as chlorogenic acid.

Nonetheless, the researchers stated that future prospective and interventional studies are warranted to confirm their findings.

Now, as someone who drinks 4-to-5 8 oz. coffees-per-day, whose interests include life improvement, health and fitness, this study certainly caught my interest!

And I’ve created videos in the past discussing other health benefits associated with coffee consumption, including but not limited to improved fat loss and longevity. Simply search this channel for the keyword “coffee” to access those videos.

I am certainly a proponent of coffee consumption for the purpose of health improvement. Nonetheless, I urge you all to enjoy coffee responsibly. If you are particularly sensitive to caffeine, then either consume your coffee earlier in the day, or drink decaf. In the case of this particular paper, the hormonal benefits were consistent regardless of whether the coffee consumed was caffeinated or not. Granted, that isn’t the case for all of the coffee research that I’ve covered, such as the one regarding longevity from my video published February 9th, 2017.

Anyway, leave your thoughts and comments below.
