The biggest cause of low testosterone
The most obvious, in-your-face cause of low testosterone is something that is probably in your diet everyday: cow milk.
Question: What is the one thing in common with all dairy products?
Answer: It comes from female animals. Of course!
This fact alone is not a big deal. Humans have been eating dairy for centuries and we're doing fine with that reproduction thing. But you may not realize just how much estrogen you're getting when you eat commercial milk produced from hormone-driven or pregnant cows. A study in Japan found a direct link between deceased testosterone levels and increased estrogen in adult males after milk intake (1).
Moreover, the concentration of estrogen in cow's milk has become much higher than was previously understood over the last several years (2). This fact alone may be responsible for the remarkable drop in human sperm quality that has been recorded in recent years (3).
Evidence is strongly indicates that drinking milk from today's cows is a cause of low testosterone.
So what can you do about this?
First things first, you can stop buying the cheap milk. That's right, spend a little more money and get milk and dairy products that are certified to be free from added hormones. This actually goes beyond the simple ceritification of bGH free. That's just the growth hormone that is added to make the animals bigger. You also need to watch out for added estrogen and hormones that stretch out the gestation period of the cows. Those added hormones are the cause of low testosterone, so check to make sure you are clear there.
But there's more. Even if you get the most vegan grass fed, hormone-free cow milk around, you're still drinking a liquid from a pregnant or lactating female animals. It's still loaded with estrogen!!! Cutting down on your dairy intake remains the hands-down easiest way to eliminate estrogen, a cause of low testosterone, from your diet.
