Fact is that estrogen - even though it's called the female hormone - is also present in the male body.
It has some functions, for joints and memory mainly, but in excess it leads to problems such as: man boobs, mood swings, feminizing body changes, and generally, lack of masculine traits with increased feminine kind.
Estrogen in males is primarily produced from testosterone, as an enzyme called aromatase, converts T to E.
Now, there are several foods that can block the aromatase enzyme (resulting in more testosterone, less estrogen) and block and downregulate the estrogen receptors (making estrogen less effective in the body).
In this article, you'll learn about the three surprising foods that are anti-estrogenic:
Liver is loaded with nutrients.
...But perhaps the most important of these nutrients is choline, a water-soluble vitamin that acts as a methyl donor in the body.
When you consume adequate amounts of choline, you're introducing methyl rings into your body. Estrogen is structurally incomplete and lacks one methyl ring in its structure. Methylating it makes it easier for the liver to remove it from the body.
#2. Citrus Fruits
Not only are citrus fruits high in fructose (which can lower SHBG, make androgens more active, and boost thyroid function)...
Quercetin (a powerful aromatase blocker), limonoids, and naringening to name a few.
Bottom line being that for anyone seeking to lower estrogen, increase testosterone, and boost thyroid function, drinking 1-2 quarts of non-concentrated citrus fruit juice per day would be a great idea.
#1. White Button Mushrooms
Research on breast cancer (which is believed to be somewhat caused by too high estrogen levels) has shown us some impressive benefits of white button mushrooms.
Specifically in their effect of blocking the aromatase enzyme (which works by converting free-testosterone into estrogen).
According to several studies, white button mushrooms as well as the supplemental extracts of them, are potent at blocking the enzyme aromatase, and thus can fairly effectively reduce estrogen levels (study, study, study).
