In this newsletter, I want to talk about what factors influence testosterone and estrogen levels as a man gets older.
And specifically, I want to tell you about two VERY important findings.
The first thing I want to do is put to rest the myth that testosterone always declines rapidly as a man ages.
It’s just not true.
This chart is a little confusing, but only healthy men were studied.
We’ll be talking about them quite a bit today.
Let’s take a look at this:
The chart shows that over 80% of aging men had testosterone levels over 300.
Note that these are healthy aging men.
Keep in mind that this study was done in the 1990s.
And about 1/3 of these healthy elderly men had normal testosterone levels.
That’s normal even for a far younger man:
It is quite possible to be in this “high T” group, even as you enter your 70s, 80s, or 90s.
It is true that as you get much older, men’s testosterone drops.
But this is not because the men are getting older.
It’s because the men are getting sicker as they get older.
It is the sickness that results in low testosterone.
And so the medical community focuses on raising testosterone levels in men rather than curing the cause.
There are ways how to increase your testosterone naturally.
Boost testosterone levels by cutting estrogenic foods.
It also pays to lower your fat mass and drink less (or no) alcohol.
You should also be physically active and have lots of sex.
And when I say you should be physically active, I don’t mean working out.
You can just have a robust lifestyle that keeps you moving and not stuck sitting for hours on end.
There is a connection between exercise and testosterone levels, but it’s not necessary to work out.
All these factors have been shown to raise testosterone.
Another study bears the same message but shows a huge decline in testosterone levels over 20 or 30 years.
It is a big problem that men’s testosterone levels have been plummeting.
So a man who was 75 years old in 1980 had a testosterone level that was probably twice as high as a 75-year old man today.
This chart was taken from a study done in the mid-1990s.
Testosterone levels have been plummeting ever since.
Note that it follows men at the same ages.
You can see that all men’s testosterone levels been falling dramatically since 1980.
It’s much much worse today.
Men routinely have a testosterone level of 200 or 300 — and this is for men who are far younger than 74.
So what’s changed between now and the “old days?”
If you ask most people, they’ll say sugar and white flour consumption is higher.
But I think the truth is quite different.
I think that there are two reasons for lower testosterone rates over the last few decades.
People are highly medicated today.
Polypharmacy is the norm, with many older men taking 5 to 10 medications at one time.
The other reason is that we are consuming high levels of polyunsaturated fatty acids which we never did before.
These PUFAs lower metabolism and testosterone and they make us sick.
Of course, it’s difficult to find studies that bear all this out all at once.
Those studies are not easily funded.
But if you continue reading Daily Medical Discoveries, I’ll show them to you.
So we’ve just seen how testosterone levels can stay high even as you get quite old.
And we’ve seen how testosterone levels correlate with health.
We’ve seen that in general, as people become sicker, testosterone levels have been plummeting.
