What Are Probiotics Benefits? 11 Signs You’re Deficient And What To Do About It

Probiotics Benefits

Hippocrates is famous for saying, “All disease begins in the gut.”

2500 years later, science is proving how right he was. Thousands of studies link an unhealthy gastrointestinal tract to an increasing number of physical and mental diseases, including diabetes, depression, and even Parkinsons’ disease and cancer.

We’re learning that a healthy balance of “good” gut bacteria relative to the bad ones is critical to well being in more ways than we’ve ever known. And key to that balance is the role of probiotics.

I’ve got a huge list of reasons why you need to get more probiotics in your diet. Probiotics benefits can be life-changing for people who have been suffering for years–you’ll be surprised at the range of symptoms due to a simple lack of enough (or the right kind) of probiotics!

But first, a recap of what probiotics are and what they do.

What Are Probiotics?

A healthy adult human should be host to 3-5 pounds of these microbes–at least 70 trillion of these “good guys!”

Probiotics are the “good” or “friendly” bacteria in the GI tract that are markers for good digestive health. A healthy adult human should be host to 3-5 pounds of these microbes–at least 70 trillion of these “good guys!”  That’s more bacterial cells in the host than actual DNA-containing cells!

Probiotics are vital to support the immune system, brain and mood function, and absorption of food and nutrients. They control inflammation, trigger hormone production, and remove waste.

One of my heroes, Dr. Bernard Jensen, was a pioneer in GI tract health. He studied 10,000 people’s colons and noted that the healthiest people had far more beneficial bacteria than the “bad,” like communicable disease germs such as strep and staph. At that time, 30 or more years ago, he reported that Americans’ good-to-bad ratios were far too low. Since then, our ratios have gotten even worse, leading to more and more disease.

That’s because many aspects of modern life are hostile to the good gut microbes, and even encourage the growth of the bad ones.

What Determines How Many Good Bacteria You Have?

There are lots of reasons that you might struggle to have enough good bacteria in your system. Most are things you can control, but others are out of your hands. That’s why you should know what the signs of bacteria imbalance are, and what to do about it. The foods we eat, the medicines we take, the toxins we’re exposed to, stress levels, and even how we’re born all affect which microbes flourish and which ones struggle.

How Do You Know If You Need Probiotics?

There is no easy, reliable way to “measure” your gut bacteria ratios, but there are some telltale signs, situations, and symptoms that probably mean you should take steps to increase the “good guys” column in the balance sheet (more on how to do that later).

You should actively boost your probiotics if:

1. You have used antibiotics. Ever. Even once. Even decades ago. It should come as no surprise that the “anti” of “antibiotics” means that these drugs are not selective when it comes to killing off bacteria. The good “pro”biotics are wiped out along with the bad, but then a vicious cycle can start: probiotics are essential for immune function, so a gut wiped out by antibiotics can’t defend you against bugs like the flu or strep or staph. And what is prescribed for strep and other infections?  Yep. More antibiotics.

You need probiotics to rebuild your gut health if you've ever taken an antibiotic
Antibiotics kill off ALL gut bacteria–the good along with the bad!

Some care standards even require doctors, dentists, or other health professionals to administer antibiotics “proactively.” I’ve questioned that practice before, and my reasons still stand: I used to get strep as a kid, several times a year. I believe that so many courses of AB’s destroyed my immune system, and it took me years of good nutrition to recover.

And of course, the consequence of the “preventative AB” trend is MRSA infections and many other “superbugs” that are antibiotic-resistant. Plus a host of yeast problems and gut issues related to all the natural flora being destroyed in the gut from even one dose of antibiotic. And the longer it goes on, the worse it can get–I wrote about Allie’s horrific story of antibiotic-induced hell, and how she dug herself out of it.

The kicker? If you’ve taken antibiotics, your store of good bacteria does NOT recover naturally. You have to consciously take steps to replace them and restore a healthy balance.

I’ve written a few times about alternatives to antibiotics and how I helped my daughter get well without them. The key is to strengthen and support gut health.

2. You have any digestive issues. Abdominal pain is the number one symptom of insufficient probiotics.  A primary role of beneficial bacteria is to break down food for absorption. When food isn’t broken down properly, you can get any of several symptoms:

  • Acid Reflux, Heartburn, and Ulcers: without enough probiotics in the upper GI tract, you can suffer an overrun of bad bacteria such as h. Pylori, a microbe which can cause sores serious enough to lead to cancer.
  • Bloating: undigested food can begin to ferment in the intestines, and a byproduct of fermentation is gas.  The gas swells the intestines where it is trapped, causing pain and bloating as it moves through the twists and turns.
  • Flatulence: undigested, fermenting food not only produces gas (which eventually needs to escape somewhere), it can also be also extra smelly, as the undigested food begins to putrify.
  • Constipation: The colon is the final chance for probiotics to do their job. If you’ve starved them of the fiber they live on, you’ll have too small of a colony to keep your stools soft and moving.
  • Irritable Bowel Syndrome: The most common GI disorder in the world, this painful disease is related to constipation and other bowel issues, and the latest studies show probiotic therapy to be useful.
  • Diarrhea: One job of colon microbes is to reabsorb water from the stool as it passes through. If an infection (or antibiotics) has wiped the microbes out, too much water is left in the colon, and it passes as diarrhea, putting you at risk for dehydration.

3. You catch every bug that goes around. The Human Microbiome Project has spent millions of dollars to catalog “microbiome communities” in people with different diseases. The more data mounts, the clearer it becomes that a varied and healthy gut population has everything to do with a strong immune system and resistance to disease, including cancer.

Beneficial bacteria tackle all the different kinds invaders that come into your body through all the different channels–breathing, touching, eating, sexual contact, etc. Bacteria have specialized jobs that vary from strain to strain, and they work to fight the baddies in different ways. Some of those jobs include:

  • Crowding out invaders by sheer number, keeping them from feeding and multiplying.
  • Strengthening and guarding gut and other cell linings, only allowing molecules they recognize to get through.
  • Regulating the inflammation response–enough action to attack pathogens, without going overboard and attacking your own systems, resulting in allergic or autoimmune disorders.
  • Maintaining pH levels that are inhospitable to infectious bacteria.
  • Being “support staff” to other good bacteria, keeping them fed or carrying off their waste.
  • Breaking down foods into nutrients the body can use to create white blood cells and repair damage.

4. You eat toxic food, including sugar. The Standard American Diet includes “foods” that would upset microbial balance on their own, but the combination common to most SAD eaters is truly toxic. They include:

  • Sugar: Sugar of any kind feeds bad bacteria and yeast organisms, all of which can quickly overwhelm a gut biome too low on the probiotics to fight them.
  • Processed Food: Processed food, with low-to-no natural fiber, feeds only the beneficial bacteria in the upper GI tract. It is digested before it hits the large intestine, starving the beneficial bacteria there and setting you up for colon disorders and disease.
  • Artificial Sweeteners: Besides being neurotoxic, artificial sweeteners have been shown to increase the bacteria associated with glucose intolerance and Type 2 diabetes.
  • GMOs: Hybridized grains have been linked with the pain and inflammation of “leaky gut,” by damaging the bacteria that are responsible for maintaining the gut lining.
  • Fast food: The meats and fried foods common to fast food restaurants feed bad bacteria and starve the good bacteria of fiber and prebiotics that they need to live on.
  • Over-the-counter medications: anti-inflammatories such as ibuprofen and acetaminophen are highly damaging to gut linings and the beneficial bacteria that live there.

5. You are depressed, anxious, stressed, or have other mood, memory, or cognitive symptoms. Some of the most exciting studies released recently show that mental health is closely related to gut health. In fact, the link is so strong, it’s being called the “gut-brain axis.”

Recent studies show that mental health is so closely related to gut health, that it’s being called the “gut-brain axis.”

Seratonin and other neurotransmitters responsible for feelings of well-being are profoundly influenced by any changes in your microbiome. In fact, 90% of your body’s serotonin is produced in your gut! The gut and brain communicate with each other via the vagus nerve, a cranial nerve that runs from the brain stem down to the abdomen. When the brain senses enough serotonin in the gut, it lowers stress hormones like cortisol, helping you feel more calm, relaxed, and content.

The effects go far beyond stress. A 2017 metastudy showed improvements in symptoms of depression, anxiety, and even memory loss after participants took sufficient levels of probiotics.

6. You were born via Caesarean section (really!).  The makeup of your gut microbiome is “hereditary,” meaning that most of the bacteria is passed from mother to baby during a vaginal birth (just as it was passed to the mother from her mother). Babies born vaginally have a much richer variety of bacteria in the weeks immediately following birth than those arriving via the more sterile environment of a C-section.

This early biodiversity can mean better long-term outcomes, but a C-section baby can catch up if parents are diligent about making sure baby gets enough probiotics, either through breastfeeding or supplemented formula.

7. You can’t sleep. It turns out that your gut health has a lot to do with how restfully you sleep.

Remember that “gut-brain axis?” Your microbiome is responsible for making the amino acid tryptophan, a precursor to both serotonin and melatonin, the hormone that regulates sleep-wake cycles. If your gut microbes don’t have enough diversity or numbers to produce sufficient tryptophan, your brain can’t relax and turn off thoughts for the night.

Of course, the serotonin itself is important for sleep, by preventing disorders like depression and anxiety that tend to disrupt sleeping patterns.

Your gut is also responsible for producing GABA, an amino acid that is essential for restorative sleep. GABA works to calm the central nervous system, and even quiets various forms of pain that can keep you from getting enough z’s.

Making sure you get enough probiotics during the day will make all the difference at night.

8. You’re gaining weight. Weight-loss promises are always a big draw, and diet fads come and go while people look for the next big thing. But managing your weight could be as simple as making sure you get enough probiotic-rich food!

And though researchers are just in the beginning phases of understanding how the gut microbiome affects things like fat metabolism and body mass, it’s clear that it does play a role.

A recent study showed that probiotics signal the body to break down fat into forms that cells can use for energy, instead of just storing the fat intact. Probiotics “reduced the body weight, body fat percentage, body fat mass and subcutaneous fat area in overweight subjects.”

9. You have acne, rosacea, eczema, or other skin disorders. Your skin is home to its own colonies of bacteria. In fact, the skin has its own microbiome, science is discovering. So healthy, clear skin relies on maintaining good bacteria, both inside and out. Here’s what we know about three common skin conditions and how probiotics can help:

  • Acne: One common cause of acne is a particular group of bacteria, so it has often been treated with antibiotics to kill them (and, unfortunately, all the good bacteria, too). Some bacteria produce antimicrobials, helping skin clear from within–and new probiotic treatments to apply directly to the skin are promising, as well.
  • Rosacea: As with acne, rosacea flare-ups are complex, and there are several ways that oral or topical probiotics can help: as a protective, antimicrobial shield if used topically, and as a stress-calmer and inflammation-tamer when taken orally, reducing breakouts.
  • Eczema: Studies on infants at risk for eczema have shown that when the mother takes probiotics before and after birth, the babies have a more diverse microbiome, and are less likely to develop eczema.
Fiber from whole-food sources supports healthy gut flora
Whole foods like fruits, vegetables, and whole grains are packed full of fiber…and that fiber feeds the good bacteria in your colon!

10. You don’t eat your veggies. It’s all about fiber! Fiber from whole grains, fruits, and vegetables are not actually digested by humans–it’s food for the billions of friendly bacteria that live in your colon. It’s a symbiotic relationship: you feed the colon’s bacterial colony, and they take care of you in countless ways. Fiber has other benefits, of course–it provides bulk to move wastes through the colon and out of your body, plus it holds enough water to keep stools soft and avoid constipation. Eat your veggies!

11. You are over age 40. Aging bodies have a harder time maintaining the balance of beneficial vs. harmful gut bacteria. The growing imbalance leads to deteriorating gut linings, susceptibility to disease, and increasing inflammation (and even more rapid aging).

People over 40 need to be deliberate and diligent about making sure they get lots of probiotics (and the prebiotics that feed them) in their diets, and should probably supplement, as well.

How Do You Get Enough Probiotics?

Helping people heal their gut with whole foods has been a passion of mine from Day 1.  It’s a whole chapter in 12 Steps to Whole Foods, and I’ve got a Video Masterclass series about it.  Here are the ways I suggest making sure you get enough probiotics, daily:

1. Eat cultured foods. Are you scared of fermented food? Cultured and fermented foods are part of your diet already if you eat yogurt or sauerkraut or kefir.

Every culture of the world eats cultured foods. My work focuses on culturing vegetables, optionally some raw, antibiotic- and hormone-free milk, or coconut liquid. In fact, I now culture my coconut liquid before using it in Hot Pink Breakfast Smoothie, which is one of my most-loved recipes in the 12 Steps course where we shift to whole-foods breakfasts.

Yogurt always comes up when discussing cultured foods–make sure you skip the fake flavorings and sweeteners. And if you’re buying pasteurized stuff, the cultures are likely already dead. Try making your own, with raw, hormone-free milk.

Check out my Facebook Live where I ate 10-year old RAW cabbage…and lived to tell about it!  We talked about the importance of fermented and cultured food, and getting over the fear of both making and eating them!

You can also make your own kefir–it’s a cheap and easy way to rehab and strengthen your microbiome that gives you more diversity in healthy microbes than yogurt does.

I have an entire Rehab Your Gut With Food video in the 12 Steps to Whole Foods Video Masterclass to learn more.

2. Take probiotic supplements. Not all probiotic supplements are created equal! Twenty years ago, the first probiotic supplements were just acidophilus, or perhaps two or three strains. Then we learned that there are actually hundreds of strains of healthy bacteria in the human gut, so the more variety, the better, for colonizing a strong microbiome. Look for a supplement that has:

  • At least 10-15 strains of probiotics (the more, the better!).  Since different bacteria do different jobs, you need a broad diversity of types to strengthen and colonize your gut.
  • Fresh ingredients with live cultures: Many probiotic supplements have been in the supply chain too long, and the cultures are old and dead. In a recent Facebook Live video, I show you an at-home experiment to do overnight that will show you if your probiotic is still viable.
  • An added prebiotic: Prebiotics feed probiotics, increasing their number and optimizing their ability to do their work in the gut.
  • Digestive enzymes: good digestion also requires enzymes in your diet. Enzymes break down proteins, fats, and carbs, these nutrients so they can be better used by your gut flora, as they travel through the digestive tract.

Since I couldn’t find a probiotic supplement that fit all those requirements, I researched and made my own, so we could all have live cultures, made in small batches. Because I want small batches with very little time in the supply chain, we’re often sold out! Check out PreZymePro in the GSG store!

The good news is that getting and maintaining a good gut bacteria balance is completely doable.  Knowing where you’re at risk, and what to do about it, are important first steps.

  1. I don’t believe and promote PRObiotic. Supplements are not the way to good health. People needs to EAT their food, and fruits and veggie are loaded with soluble fiber (Prebiotic) for our microbiome. So your green smoothies are good source.
