Should You Eat Saukerkraut Every Day? (Here’s What Science Says) | EP 399.C

Sometimes the simplest foods can have the biggest impact on your health.

Fermented foods like sauerkraut have been used for generations, but what happens when

you eat them every single day?

Today we're taking a closer look at what happens of 30 days of sauerkraut eating can

do for your gut and overall wellness.

I'll walk you through the potential benefits, what to expect, and whether this daily

habit is worth it.

So stay tuned.

Craving something decadent like a double fudge brownie, lasagna, or an almond-joy muffin

that's secretly good for you, then you'll love my Dr. Gundry newsletter each week.

I send out an exclusive recipe that not only tastes incredible, but also supports your

gut, your heart, and your long-term health.

From snacks to desserts, these recipes prove you don't have to give up flavor to eat right.

You just need the right ingredients and a little guidance.

But if you eat sauerkraut or kimchi every day for 30 days, all right.

So sauerkraut and kimchi are actually becoming readily accessible.

So what the heck is that?

Well, if you're new to fermented foods, fermented cabbage has been around probably since

the beginning of civilization.

And cheese, as many of you know, is from Korea, and has been a staple of Korean cuisine

for centuries.

Typically, kimchi is made from cabbage.

It can be made from radishes or scallions or cucumbers, or often a combination of these

vegetables.

Sauerkraut traditionally is made from cabbage.

What exactly is the reason to do this?

Well, several reasons.

First of all, remember that long ago, there was no refrigeration.

And so a vegetable like cabbage, which is actually pretty good for storing in a root

cellar, eventually goes bad.

But if you use fermentation, you actually break down a lot of the sugars into compounds

that preserve that food for an extended period of time.

Also, the fermentation process produces a lot of hugely, we now know, beneficial compounds

that are good for your health.

So let's just talk about the fermentation process for a minute.

Bacteria and or yeast eat sugar.

And they turn that sugar into ATP, the energy currency, through a process called glycolysis,

which we call fermentation.

It's actually a very inefficient process.

You and I don't use much glycolysis.

We use oxidative phosphorylation, but we won't talk about that today.

So in the process of glycolysis, you convert these sugar molecules among other things

into alcohol.

That's why when you ferment grapes, you get wine that has alcohol in it.

When you ferment yogurts, you actually get a small amount of alcohol in it through the

fermentation.

And certainly with kombucha, you do get a small amount of alcohol.

But the big benefit is that you get what are called postbiotics.

And postbiotics are the leftover products of fermentation.

Those include the dead bacteria cell walls and or the dead yeast cell walls.

And if you read my new book Gut Check, you know that these dead bacteria or yeast carry

information.

And they carry information down to your gut after you swallow them, regardless of whether

they're living or dead.

Now that brings me to an important point.

You will see in my cold foods, you will see fresh sauerkraut or fresh kimchi.

Then you will also find sauerkraut or kimchi in glass jars or even cans where they have

been pasteurized.

The great news is that it really doesn't matter whether those bacteria are living or dead

honest.

Most of the time when we eat living bacteria in these foods, those bacteria are killed

by our stomach acid.

They never make it past stomach acid.

But the dead bacteria does make it past stomach acid.

And it turns out it's the cell wall of the bacteria that actually carries the information

that tells our gut microbiome kind of who's in the house.

And that's really exciting news.

This was first proven a few years ago by the husband and wife team at Stanford, the

Sonnenbergs.

And I've talked about the study again, but it's important to hear this study.

We know that prebiotics are really good for friendly bacteria.

It's what our probiotics, friendly bacteria, want to eat.

And it makes sense that if we ate a lot of prebiotic fiber, that our friendly bacteria

would be really happy.

And our friendly bacteria would make us really happy, not so fast.

The Sonnenbergs took some humans.

They gave them a ton of prebiotic fiber.

And they looked at whether or not they had improved gut microbiome diversity.

The more different kinds of bacteria in your gut, the better.

Let's leave it at that.

The less types of bacteria in your gut, the worse.

So they looked at the microbiome diversity.

And all this fiber didn't change the gut diversity.

And they looked at markers of inflammation.

And all this fiber didn't change the markers of inflammation.

And you go, well, what the heck?

I thought that, you know, that's what was needed.

So then they took another group.

They gave them the same prebiotic fiber, but this time they gave them fermented foods.

Now it was primarily in the form of yogurt and key fears.

But the point is these had postbiotics in them.

And lo and behold, when the prebiotic fiber was combined with the postbiotics from the

fermented foods, lo and behold, the gut microbiome diversity bloomed lots of new species.

And lo and behold, the markers of inflammation plummeted.

I'm Jen Scheiman, registered dietician nutritionist and director of science communications

at Timeline.

And I want to share a simple way to think about healthy aging that most people overlook.

A lot of us focus on diet, supplements, or exercise, but one of the biggest drivers

of how we age starts in our cells.

As we get older, they naturally make less energy, and when that happens, it can show up

as feeling more tired, less resilient, or like it takes more effort to do the things

you enjoy.

That's why Timeline created mitochondria gummies.

Mydopure is the only clinically proven form of uralithane, a molecule that helps renew

your mitochondria, those energy-producing powerhouses in your cells.

Supporting mitochondrial health is one of the key ways to support healthy aging at the

biological level.

Mydopure gummies make this easy.

Just two gummies a day deliver a research-backed dose of uralithane in a sugar-free, vegan

format that's simple to stay consistent with.

And now Timeline is offering 20% off mydopure gummies.

You can learn more and get the offer at Timeline.com-backslash-gundry.

So, getting back to Sour Crout and Kim Chi, what's going on?

Well, here's the one to punch.

You now have the fermented foods, you have the postbiotics, the dead bacteria, the dead

used, all the other short-chain fatty acids that are made with fermentation, plus you

got oodles of fiber in the various forms of cabbages, radishes, scallions that the gut

bacteria then eat because they've been primed with the postbiotics and the fermented food.

So, that's what these ancient cultures obviously knew.

Now, which came first?

Did they know that that's why they were doing it?

Probably not.

We didn't have these really cool tests that we have now.

But the number one knew that they could preserve foods that they otherwise couldn't store

using this technique.

And oh, by the way, people through centuries who were eating foods preserved this way were

clearly healthier than people who weren't doing it.

The other thing that these cultures learn almost from day one, that plant compounds that

exist in a lot of foods to prevent us from eating them.

And these are the plant defense compounds like lectins, like oxalates.

These were eaten in the fermentation process.

That actually brings me up to one of the questions that we've gotten about kimchi.

Much of kimchi has red pepper flakes in them.

And as you know, the peel and the seeds of peppers are loaded with lectins.

And yet, I tell you, kimchi, what gives?

Well, it turns out that the fermentation process eats the lectins even in the peppers.

That's why hot pepper sauces that have been fermented are perfectly safe to eat.

Whereas hot peppers that haven't been fermented are not safe to eat unless you peel and

deced them.

So that explains the paradox of why I would allow you to have those pepper flakes in your

kimchi because they've been fermented and rendered harmless.

Now, what happens if you eat this stuff for 30 days?

First of all, please, please, please.

If you're not used to eating fermented foods or you're not used to eating a lot of fiber,

start slow.

Your gut bacteria think fiber is delicious and they ferment that fiber and tell you how

happy they are by producing lots of gas and bloating and may even change your frequency

of your bowel movements.

Now, the good news is, if you start slow, you will adapt to that.

And within 30 days, you'll be up and running on a generous dose of sauerkraut and kimchi.

But please, please, please, don't eat the whole jar the first day.

I don't want cards and letters coming in saying, what you make me do that for, I'm miserable.

Start slow and then work your way up.

These have shown that humans who have done this actually have remarkable improvement in

inflammatory markers, have remarkable improvements in gut biodiversity.

And that's what's going to happen when you eat these foods for 30 days.

But please, please start slow.

Be careful, a number of these products, because Americans in general don't like sauer and tangy,

a lot of these products to get them more palatable will put a remarkable amount of sugar into their products.

Now, it's okay to add a little bit of sugar to start the fermentation process,

but it's not okay to add sugar to make it palatable to you.

If it really bothers you, the tartness, what I like to do is I like to use alyolose,

which is a true sugar that has no calories, but is a prebiotic in itself.

And so, use alyolose to make that taste more to your liking.

Again, read the label, look for added sugar content.

It'll surprise you how many of these companies have added a lot of sugar to make you like the product.

The other last benefit, particularly if it's made with garlic and scallions,

I've talked a lot about this.

There's some really cool compounds in garlic and scallions called Alison,

which really helps repair the lining of your blood vessels and your blood-brain barrier,

which is called the glyco-calix.

And so, anytime you can get these compounds in you, the better.

Now, it's time for the question of the week.

A question from at Little Monstrito over on YouTube on my episode about food products to never eat.

They asked when I was a little girl, my mom used to give me a bowl of plain yogurt

with sprinkled wheat germ on top.

Since it's a no, any idea what I can top yogurt off with other than fruits?

Well, yeah, top it off with chopped up nuts,

particularly walnuts, pistachios, macadamia nuts, hazelnuts, pecans,

list goes on and on, but please, in general, avoid almonds if they have the peel on them.

So many of my patients react to them, but you'll get the same crunch you're looking for

from kind of the granola wheat germ that you're putting on,

but you get so many more benefits.

And wheat germ is one of the highest concentrations of wheat germ glutinant,

which is one of the worst nasty electrons I've ever found.

Thanks for writing.

Now it's time for the review of the week.

A review at Veran Ramiston 4095 over on YouTube on my episode about how to take your supplements.

They said I am taking so many all caps supplements.

Most of them are yours, Gundry MD,

but also additional ones that have been recommended from your online health service.

I used to hate the idea of taking supplements because the costs add up.

Now, I consider it my body car payment worth every penny, because I feel amazing,

just like the commercials.

I am still a frugal gal, but I make health my priority.

Well, thanks for writing.

You know, I used to say supplements made expensive urine,

but after 30 years of measuring the effects of supplements on my patients' well-being,

and probably more importantly, on markers of health, longevity,

and overall fitness supplements supplement a well-chosen diet.

And it's exciting to see that supplements that I designed for Gundry MD

based on the results of 30 years of testing patients with these products are working for you.

And you're right, this is the only house we're going to ever live in our body.

And if we spend as much time and money on taking care of our house, our body,

that we do for our car, or our home, or our apartment, or even the clothes we wear,

it's amazing what happens.

So, thanks for writing.

You're right, this stuff unfortunately is expensive,

and I always try to get you a good deal whenever I can,

because I want everyone to have great health.

Did you know the air inside your home could be up to 100 times more toxic than the air outside?

Chemicals from your furniture and cleaning products, invisible harmful particles from your stove,

and candles, mold spores floating through every room.

These toxic invaders are silently linked to brain fog, fatigue, heart disease, and more.

That's why I created Total Air.

From my new home wellness brand, HomeKind, Total Air uses a true surgical grade HEPA filter.

The same standard I trusted in the operating room.

Plus, an activated carbon layer for chemicals,

and microband technology to stop molding bacteria from spreading.
