PREbiotics vs PRObiotics: What’s the difference?!


I had a client ask me what the difference is between probiotics and prebiotics - so let’s talk about it!

Many people are popping a probiotic pill every day , and not really thinking much more about it.

But here's what's actually happening inside your gut - your probiotic doesn't have much to work with if you're not feeding it. That's where PREbiotics come in. And nope, a trendy soda with "prebiotic fiber" on the label doesn't count (keep reading to learn more…).

What's the difference, actually?

PRObiotics are live beneficial bacteria. You want them in your gut.

PREbiotics are the fiber those bacteria eat. You want to be consuming prebiotics constantly to feed that bacteria.

You can think of probiotics as seeds, and prebiotics as the soil. You can throw seeds into dry, barren dirt every single day - they're not going to thrive.

How often should you be including each?

PRObiotics: once a day is enough. Fermented foods like sauerkraut, kimchi, or yogurt are perfect sources.

PREbiotics: EVERY single meal (yup). This is what so many people don’t realize! (but, if you eat a healthy balanced diet, you might already be doing it without realizing).

Here's a list of prebiotic foods:

  • legumes
  • avocado
  • apples
  • blackberries
  • raspberries
  • nuts
  • mushrooms
  • shirataki noodles
  • asparagus
  • jicama
  • turnips
  • parsnips
  • onion
  • garlic
  • shallots
  • carrots
  • leeks
  • dandelion greens
  • radishes
  • cabbage
  • brussels sprouts

It’s not as complicated as it sounds! Some easy ways to add prebiotics in:

  • Throw a couple tablespoons of black beans into your omelet
  • Sauté up onions and garlic for all dishes
  • Dip your veggies into hummus instead of ranch
  • Add apples or berries into your salads

Not all fiber is created equal

Most of the fiber supplements people are using (inulin, wheat dextrin, the trendy fermentable stuff) get rapidly broken down by gut bacteria. That produces a LOT of gas... but questionable metabolic benefit.

The real driver of clinically proven effects - improved blood sugar control, lower LDL, appetite regulation, normalized stool consistency - is viscosity, or gel formation. And, only a few fibers actually do this.

Psyllium husk is one of them. Beta glucan is another. Psyllium forms a thick, viscous gel that slows nutrient absorption, improves glycemic control, and lowers LDL cholesterol. The evidence behind it is on a completely different level than most fiber supplements out there!

Prebiotic sodas: what’s the deal?

I know they're everywhere right now - and I love to have one once in a while, too! They're fizzy and fun and they say "prebiotic" on the can. But they are NOT a substitute for real food.

Here's why. When you eat a prebiotic-rich food, you're getting a LOT more than one isolated fiber. You're getting:

  • Pectin
  • Mucilage
  • Resistant starch
  • Cellulose
  • Inulin

...all working together in ways a can of soda with added chicory root can never replicate. The synergy in real food is the whole point. No supplement, drink, or powder can capture the complexity of what whole foods deliver to your microbiome.

To summarize:

Eat your vegetables.

Feed your bacteria.

This is what makes probiotics actually work.

In health,

Still pregnant as I write this... it's Tuesday 6/23 and baby is now over a week late, which feels like the universe giving me a lesson to surrender! Baby will come when baby is ready, and all I can do is let go and trust the timing... so we'll see when this little one decides to make an appearance! Last weekend we celebrated a small Blessingway. In case you've never heard of one, a Blessingway is a sacred ceremony traditionally practiced by the Navajo people to honor and support a woman as...

So this is what I've been doing to my drinking water every day... yup, setting it out in the sun. It sounds SO ridiculous and woo-woo, I know. But what the sun is actually doing is helping structure my water. Let’s talk about what the heck that means! What is structured water? The water inside your cells isn't the same as the water coming out of your tap. In your body, water exists in a gel-like state called structured water (you might also hear it called EZ, or exclusion zone water). The...

I had a client tell me recently that she eats tons of fiber every day... and then when I asked her to track her food journal, it was very eye-opening. The real number came out somewhere between 4 and 6 grams daily (she was shooting for at least 25 grams). Yikes. This happens all the time! Most of us assume that if we're having a salad most days, we're reaching our fiber goals (I used to think this, too!). But the reality is that something like a Caesar salad gets you to about 2 grams of...
