Fermenting foods: it’s freaking me out!
Dear GreenSmoothieGirl: I really like the idea of adding the Rejuvelac as my green smoothie base, but I’m honestly totally freaked out to leave something perishable on my countertop in an unsealed container for several days. What are the chances that “bad bacteria” get in there and make me sick? I really appreciate any feedback you have. It sounds like a great opportunity to make green smoothies do even more for me, but I can’t get over the initial concept. –Grace
Answer: Grace, I think it might help if I explain the concept a bit more. Fermented foods are part of your diet already, if you eat yogurt or sauerkraut, or even beer. The manufacturer had to let it sit at room temperature for a time, to grow the cultures.
Also, before refrigeration, human beings had a stronger inner terrain and microbes rarely harmed them. Of course, now we have antibiotics that have seriously damaged most people’s balance of beneficial microorganisms colonizing the digestive tract. We also have refined foods weakening us, and few, if any, cultured foods strengthening us. We now seem to believe that killing a couple million of the billions of microscopic critters around us will somehow do the trick.
It’s a weird modern concept that everything we eat has to be sterilized—ancient peoples lived amongst billions of organisms very peacefully for thousands of years. So maybe our food is sterilized, fumigated, pasteurized, irradiated…..but there are billions of organisms everywhere ELSE (which makes the antibiotic wipes a pointless waste of money).
So, it feels unnatural to you but only because of our strange modern traditions, and the fact that we’ve gotten away from eating foods that nurture our gut’s need for healthy colonization. Just ONE course of antibiotics can change the gut’s internal terrain forever.
Every culture of the world eats cultured foods. Some chew up a food and spit it, with their saliva, into an earthen pot, and drink it a week later. (I won’t be teaching you those methods, don’t worry.) There are literally hundreds of types of cultured foods, in traditional / indigenous peoples, and in people who have not completely adopted processed diets.
The most complete and well known work on this concept is Sally Fallon’s Nourishing Traditions, which has some good info but advocates for lots of meat and dairy and a very rich diet. My 12 Steps to Whole Foods program deals with it in a condensed way in Ch. 8 and uses what I feel are a do-able, moderate amount of probiotic foods that do not require us to purchase $10/lb. animal parts. My work focuses on culturing vegetables, optionally some raw, antibiotic- and hormone-free milk, or coconut liquid. (I now culture my coconut liquid before using it in Hot Pink Breakfast Smoothie).
My blog on 9/15 talks about learning vicariously through others—the examples I gave were learning from others’ health disasters. But you can learn from my health victories, too. Does it help you to know that I have had a quart or a half gallon of raw kefir, or yogurt, or coconut kefir, or sprouts, or Rejuvelac, or sauerkraut, on my counter, pretty much every day of my life for the past 17 years? We have had zero instances of problems, illness, food poisoning.
It also helps if you understand the process of how food has historically been preserved. You can preserve foods a few ways. One, drying it to dramatically slow oxidation, which often involves lots of salt. Two, can it by killing all its lifeforce (enzymes and vitamins) so that there’s very little to oxidize, and then sealing it against air and bacteria. Third, utilizing lactobacillus and other beneficial organisms and lactic acid to break down the proteins and preserve the food (fermenting).
The way I make sauerkraut (see Ch. 8 of 12 Steps) is that the unrefined salt preserves it for a few days while the (slower) lactic acid begins to take over. I have two-year old raw sauerkraut (that I preserved with whey from my yogurt/kefir) that has been unsealed (but covered tightly with a lid) that we are still eating. It’s too soft, and it’s better, texture-wise, at six months old. But it’s preserved, and the healthy bacteria help my family stay healthy.
It might help to address the semantics. The word “fermented” has a negative connotation. (Although beer drinkers who wouldn’t be caught dead eating fermented vegetables drink PLENTY of fermentation.) When you think of fermented, do you think of ROTTEN? We aren’t eating any rotten foods at my house. We could mentally replace that word with a much nicer one: cultured!
So, don’t eat fermented foods. Eat cultured ones!
If “bad” bacteria gets into your cultured foods and makes them “go bad,” you will know. They will taste bad and/or mold. I have almost never had this happen. Once it happened with a bottle of sauerkraut. Never with kefir or Rejuvelac.
My Rejuvelac ferments in a day. At CHI, they told me 3-5 days, but mine tastes plenty tart 24 hours after I blend the sprouts and water, and put it on the counter to grow (aka ferment, aka culture).
Here’s my new video showing this easy, inexpensive habit that has the potential to see you through the winter without viruses or infections!

$30 bucks for a bottle of Kombucha? Does it have diamonds etched on it or something? 🙂 Every health food store in Denver sells 16 oz bottles for about from $2.50-$2.99.
For those who want alternatives to quinoa and wheat: buckwheat and rye work very, very well for Rejuvelac. My sister thinks rye makes a sweeter tasting Rejuvelac. Make sure the buckwheat you buy is NOT toasted (otherwise it won’t sprout). Toasted buckwheat is usually labeled as Kasha and raw buckwheat is usually known as buckwheat groats.
thanks for the rejuvelac video. I’ll be making it and putting in the smoothies. very helpful
Just made my first batch and drinking it in my green smoothie. I can’t even tell it is in there. Thank you for your videos, keep posting them. That is how I learn best.
I’ve heard of this before and you’re right; it sounded awful. However, just watching you demonstrate how simple it is and the health benefits, I have some on my counter now “culturing”. Can’t wait to have it in my smoothie tomorrow. Thank you for demystifying this probiotic.
I did this, but when it was finished fermenting it had a thick 1/4 inch yellow layer on the top. i skimmed it off and put the liquid in the fridge. Can I drink it or did I do something wrong? Is it safe? I did just what you did on your video so I don’t know how it could be wrong. Just don’t want to go forward until I know what this stuff on top is.
Thanks!!
I just started soaking some quinoa to try to making my first batch. I’m so excited! I’m gluten intolerant, so won’t do the wheat berries, but the quinoa is perfect. Thank you Robyn!
Hi Robyn,
This is an excellent video. I def. want to give this a try. Thanks for the info!
Hi Robyn, what are you thoughts on the new book out by Timothy Ferriss, 4-hour body. Do you think this is a healthy way to lose weight or not. Also, do you mix up the rejuvelac or just drink the water on top of it? Thanks Mike
Mike, I read 4-Hour Workweek and I’m generally pretty fascinated by Tim Ferriss, a really unique guy. Haven’t read 4-hour body but I’ve heard a little about it, would have to study it more. What specifically does he say that you’re wondering about? Rejuvelac: you can strain out the solids with a nutmilk bag if you want–then drink all of it. Look at my video–I blend up water and the sprouted wheat berries.
Also, can this be consumed during pregnancy and breastfeeding?
made my first 2 batches one with spelt berries one with quinoa everything was going very well, tested the taste along the way kinda lemony perfect, but when I went to bottle it for the fridge the next day it tastes like feta cheese,. does that means it is off. I have googled around the internet and can’t find out if that is good or bad. I am afraid to drink it but don’t want to through it out. I guess we learn as we go.
Still good, just stronger—unless it tastes like it’s gone bad. I’ve not had anything go bad yet in a few weeks of making it.
After it ferments on the counter a day or two i put some in a sealed mason jar in the back of the fridge…..after a while it begins to carbonate…..I like it both ways. I have also made some with the “jelly” palm fruits that fell too the ground in my neighbors yard, they just let them spoil on the ground so i sent my kids over to pick the good fruit, we ate some and i put some in a jar in water in the fridge, it fermented well and tastes good.
I had the same problem as Katrina. What’s with the yellow stuff on top? It smells pretty bad too…hmm.
April, does it smell bad, or fermented? It should be a little tart, lemony. Not rotten. I’ve never had any fermented food go “bad,” so I kind of doubt that’s it–you probably just aren’t used to it. The stuff on top is the solids from the sprouts you blended in. Best idea if you’re going to drink it straight is to strain that out. Nut milk bag will be easiest and most effective, or a very fine-mesh strainer. If I use it in green smoothie, I use all of it including the solids, though!
Robyn, Does drinking this help prevent just intestinal illnesses or coughs and colds as well? Do you think it is better than kefir? Thanks.
Gentry, it’s just different than kefir. Getting a few different fermented foods, for the most strains of beneficial bacteria possible, is a GREAT idea to be strong against viruses and bacterial infections, yes.
I see on your video for making rejuvelac that you are drinking the water or lighter fluid off the top of the culture sediment in the bottom of each jar. Do you ever shake up that sediment with the floating liquid and use it all, and then when you can see you are about to use up your rejuvelac in the next couple of days you restart the process of soaking the seeds etc.etc.?
Thank you SO MUCH for all your study, sharing and helping America particularly, to heal.
I love watching your videos!
Keep it up!
