"SHINGU, Wakayama -- A team of researchers in Japan has succeeded in making catfish all female with a compound found in soybeans -- a development that promises to increase the production efficiency of this and other species whose females are more valuable than males in the food market.
The team, from Kindai University's Aquaculture Research Institute and based at the institute's Shingu Station in Shingu, Wakayama Prefecture, used isoflavone -- a compound found in soybeans similar in effect to female hormones -- to create the all-female groups of catfish. The feat is a Japan first, according to the university.
As female catfish grow faster than males, "by making them all female, production efficiency will rise," commented team leader and aquaculture science associate professor Toshinao Ineno. "This can be applied to other farm-raised fish whose females are more valuable."
According to Ineno, in catfish cultivation, which has been attracting attention as an alternative to increasingly scant eel, females grow to shipping weight -- at least 600 grams -- in six to 10 months after hatching. Males, which grow more slowly, are often discarded. Though it has been known that administering female hormone turns male catfish into females, this method is banned for fish for human consumption. So Ineno came up with the idea of using soybean isoflavone, which is sold commercially as a dietary supplement...."

How clever. Except that soybean isoflavone acts like estrogen in the human body as well. But, hey, if it's not banned, it must be good for you!
Soybeans are highly estrogenic. Not enough that eating the occasional meal with soy sauce would have an effective. But, unfortunately, the two most estrogenic soy products, soybean oil and soy lecithin, are in nearly every item of processed food on store shelves.
Bread, chocolate, mayonnaise, stock, whey protein... the most random things, and pretty much anything you can think of. It's all full of soy now. And the meat you're eating... guess what they like to use as feed when raising it, these days?
Yep, I've cut out nearly all food that have soy in them, with the exception of a pizza every once in a blue moon. Since I started last fall, I've lost 50 pounds, I was 240 now I'm 190, I've had an easier time of building muscle, and my cognitive capabilities have improved.
At the minimum, cut out all foods with soy in them, it will help. If you have time to cook for yourself, buy local ingredients from farmers, many of them advertise on places like craigslist, and you can usually find a farmers market in any given farming community.
Long term the solution of course if too grow and raise all of your own food, avoiding any plants that are GMOs. Growing crops is pretty space efficient, but raising livestock isn't. In the event you don't have enough space for livestock, use a mixture of getting your meet from trusted farmers, and hunting.
Also, fractionally distill, or have a reverse osmosis filtration system for your water, if you're living in, or near a city.
