I have heard that beets may contribute to the development of male breasts. At the same time, some sources are also telling me that they raise testosterone levels? Here's a scenario: an adolescent male loves to drink beetroot juice, and he drinks a cup a day. Will this cause him to develop breasts? And does weight play a factor - e.g. will an overweight male be more vulnerable to gynecomastia than an underweight male? Like I said at the beginning, I am getting mixed answers; unless you could develop gynecomastia whilst having high testosterone levels?

Searching online for "beets testosterone" there are sources that state that beets boost testosterone levels. e.g.

The vitamin and antioxidant content of beetroot is high. It is also rich in dietary nitrates, which boost testosterone levels

Searching online for "beets gynecomastia" there are sources that state that beets increase estrogen levels (hence men should avoid beets). E.g.

Beetroots: Beetroots contain high estrogen levels, which could cause your testosterone levels to decrease. Try to avoid this food to balance your hormones.

Also from an article that says is written from a doctor but there are no references mentioned

The top foods that cause man breasts are soy products, beetroot, ....

.

If beets do cause gynecomastia that would mean that regardless of what they do to testosterone levels, they should increase estrogen abnormally high.

What is the source of this contradiction? What do reputable medical sources report on this?
