Simple Science

"All disease begins in the gut." – Hippocrates

Well, not all disease, but research from around the world has linked healthy gut bacteria – probiotics – in aiding many any health issues, such as obesity, diabetes, chronic stress, anxiety, depression, Parkinson’s and autism.

In fact, very few people think of probiotics when it comes to healthy aging (anti-aging). Spanish explorer Juan Ponce de Leon never discovered The Fountain of Youth. But, ironically, the fountain of youth was right under his nose – in his gut.

Here in this quick read, you will discover the science behind how healthy bacteria (probiotics) work in your body for increased energy, better sleep, fighting diseases, and overall better (aging) health.

We won’t get all sciencey on you, either. Because sometimes the best science is simple science.

Are you ready? Let’s hit it!


The Misinformation and Fear Mongering

But first, let’s get this out of the way and done with. There are too many websites out there that give a list of signs of having an imbalance of gut bacteria (more bad bacteria than good).

They give signs like: fatigue, headaches, thyroid problems, brain fog, mood issues, diarrhea, constipation, IBS, bad skin (acne, red flare ups). . . .

Come on now. How many other things, including stress and a bad diet, can cause all of that?

Yes, those are the signs of a bad gut, but it isn’t definite. There are not enough conclusive legitimate studies.

If you have the signs, how do you know for sure if it is your gut? Find a good gastroenterologist in your area to have a test done. Be sure to check for reviews on that doctor.

You could also try doing a food-elimination technique. Start removing certain foods from your diet to see if they have any effect on how you feel. Flour, for example. Stop eating anything with flour for about a week, and see what happens. Then move on to the next food item.

Another piece of misinformation you may have read a time or two is about swapping out, replacing bad bacteria for good bacteria. There is no “swapping out” of anything.

It’s also not necessarily good bacteria killing the bad, either. It’s more about having enough probiotics in your gut to outnumber (outgun) the bad bacteria. A balanced gut.

You still have bad bacteria in you (and probably on you), and you always will, but the bigger population of probiotics will keep the much smaller neighboring bad bacteria in line.

With that out of the way, we can now move on to the good stuff.


The term probiotic was coined fairly recently (in 1965) and is derived from the Latin “pro-” which means “for” and the Greek “-biotic” which means “life.” And antibiotics means against life.

“We help you live healthier and longer.”

Death Begins in the Gut for Many

That’s an ol’ saying – and it was probably started by gastroenterologists standing around the cooler. Here’s a little straightforward, simple science to digest on – without the fluff.


Psychobiotics is a term for probiotics that has a lowering effect for sadness, hopelessness, anxiety and stress.

Scientists have found that probiotics produce neurotransmitters such as serotonin, dopamine and GABA, all of which play a key role in mood.

In addition, they are intertwined with the immune system, which itself influences mood and behavior.

If that weren’t enough, they also help your body absorb more mg of nutrients that affect mood: B complex, zinc and magnesium.


Probiotics help decrease the odds of cancer cells forming due to five reasons:

  1. Has antifungal and antiviral properties.
  2. Helps remove (breaks down) toxins in the immune system.
  3. Breaks down toxins during metabolism, like ammonia.
  4. Helps the body absorb more milligrams of vitamins, minerals, along with healthy fats and antioxidants.
  5. Helps reduce the after effects of stress. Stress can alter healthy cells.

Research has shown that having more bad bacteria in the gut over the long-term can accelerate Alzheimer’s, in addition to other brain issues.
Another good point in having a healthy balanced gut by having more probiotics.


The exact cause of IBS is still unknown, but we do know that probiotics helps relieve IBS by outnumbering the bad bacteria. It’s the bad bacteria that plays a big role in IBS.

And because of this, probiotics fill two need with one deed by also aiding diarrhea.

Too much bad bacteria is what also causes diarrhea.


Helps give more energy because it breaks down toxins in the body, strengthens the immune system and central nervous system, and helps the body absorb more milligrams of vitamins and minerals. They also outnumbers the bad bacteria, which drains your body’s overall energy level.

Let Food Be Thy Medicine and Medicine Be Thy Food

When you get right down to it, the nitty gritty, the brass tacks, our diet plays one heck of a huge role in giving us energy, heart and brain health, better sleep, better digestion – along with a stronger immune system and cellular health.

But what if your body is not absorbing enough of the vitamins, minerals, antioxidants and omega 3? That’s when probiotics – plus a prebiotic to help the probiotics grow in strength – helps your body absorb more nutrients.

It doesn’t take much of a science degree to figure that one out.

Is Having More Probiotic Strains Better?

When it comes to multi-strain probiotics, supplement companies are using the simplest of consumer beliefs which is “more of a good thing must be better.” Actually, when we’re talking about bacteria, more means competition.

Now here’s why multiple strains don’t make a bit of sense:

Bacteria compete for survival, this is, after all, the main mechanism by which probiotics overtake the gut microflora- by overpowering existing bacterial strains. The worry with probiotic supplements boasting “Ten Different Strains!” is that those ten different strains are very likely to compete with each other for the right to live in your gut. This defeats the purpose of taking a probiotic in the first place.

The fact of the matter is that science doesn’t know yet if more bacteria are actually better for you. Multiple strains (10+) have not proven themselves to research to be any better than fewer strains.

We still don’t even know for sure how many different strains of probiotic bacteria are in the gut to begin with.

(A strain is a subdivision of a micro-organism. Like a virus, bacterium or fungus.
For example, a flu strain is a certain biological form of the influenza or flu virus.)

So sales pitches that say more is better are just that – sales pitches!

Let’s Wrap This Up

Just listen to the simple, straightforward science, don’t make it so complicated, have a healthy gut and diet, watch your stress, have good sex, and – with fingers crossed – you’ll have higher odds in your favor at having a much better, healthy-aging life.
