Make Your Gut Happy and Cool Off with Kombucha

Kombucha has a plethora of health benefits, including stellar gut health boons.

It’s almost impossible to shop in a health food store or even your neighborhood grocery store and not notice kombucha. It’s the strange-sounding drink that is popping up everywhere. While it may seem like a fad, kombucha indeed appears to be having more than 15 minutes of fame, and for good reason!

The favorite tea-based drink is one of those love it or leave it elixirs. Fans brag about the impressive health benefits, including the most notable—it’s a natural probiotic, providing gut health-loving “good bacteria.” Those who are in the “leave it” category have strong reactions to kombucha’s acidic, often sour taste (although there are tons of flavored fruity versions to try), and have a hard time getting past it.

What Is Kombucha?

Kombucha is a drink made from bacteria and yeast, tea, and sugar. It has a distinct vinegar smell and has been described as tasting like rotten apple cider or like fizzy tart apples. A starter “mother culture” of the yeast and bacteria is combined with black or green tea and allowed to ferment for about 10 days.

This symbiotic colony of bacteria and yeast is commonly known as a SCOBY. It resembles a mushroom in appearance but is entirely unrelated to fungi in nearly every way.

During fermentation, a thin layer of bacteria forms on top. After the fermentation is complete, this layer of bacteria is scooped out and used to start another brew. What’s left below is a fermented tea known as kombucha.

A Brief History of Kombucha

Kombucha dates back 2,000 years to China, where it was consumed as a common remedy to ward off everything from cancer to arthritis. It was believed to promote healing as a home-remedy for conditions such as acne, fatigue, constipation, headaches, and even symptoms of hypertension.

Health Benefits of Kombucha

Modern-day fermented foods such as kefir, sauerkraut, kimchi, and kombucha are believed to provide much needed healthy gut bacteria. Kombucha probiotics contain good bacteria that can help fight the common cold, lower cholesterol, and alleviate symptoms from digestive issues like irritable bowel syndrome and diarrhea.

The health benefits of kombucha are impressive, but when looking for definitive proof, we’re limited to animal studies. These studies show promising results, and anecdotal evidence supports similar effects in humans.

A study conducted in the early 2000s and published in Food Research International showed that kombucha can stimulate the immune system in a way that can improve resistance to certain cancers, reduce inflammation, promote digestive health, and prevent various cardiovascular diseases.

Furthermore, in a study published in the journal Biomedicine and Preventive Nutrition, scientists found that kombucha had a direct effect on downregulating prostate cancer cells, leading researchers to believe that kombucha could be a potent preventative and complementary treatment for prostate cancer.

Kombucha also contains antimicrobial and antioxidant-rich phytochemicals and phytonutrients that have been shown to promote healthy liver and kidney function, as found in this study featured in the US National Library of Medicine. Another study featured in the same organization found that kombucha can reduce complications from diabetes in diabetic laboratory rats.

Kombucha is also rich in folic acid and B vitamins, which are essential for helping the body produce and maintain new healthy cells.

Homemade Kombucha

Kombucha is relatively easy to make at home, although it comes with some warnings if you dare. Homemade kombucha requires tea, sugar, and an active starter of yeast and bacteria.

Cautionary warnings of making a homemade kombucha brew stem from brewing it in uncontrolled and unsanitary environments. Without being able to control the air surrounding the bacteria that’s growing (and which needs to have access to fresh air) the drink can quickly become contaminated and lead to many unpleasant side effects including an upset stomach or other allergic reactions, and in one case, even death.

It’s advised never to make kombucha in a ceramic pot, as the acids draw the lead out of the glaze and can contaminate the tea with dangerous toxins.

If you’re curious about kombucha, stick to the store-bought brands and consider avoiding home brewing, especially at first and mainly if you cannot guarantee a sound environment free of potentially harmful ingredients seeping into your brew.

Additional Caution for Kombucha

Kombucha is naturally alcoholic due to the fermentation process (which is similar to how wine and beer are made). The alcohol content is and continues to be a concern. In fact, in 2010 Whole Foods reportedly pulled some brands of kombucha from their shelves, concerned that the alcohol content listed in the ingredients was much higher than claimed.

It’s common for most store brews to contain less than 0.5% alcohol by volume (or ABV). Kombucha that contains up to 3% alcohol is considered an alcoholic beverage and only sold to those legally able to purchase alcohol. While getting buzzed off of kombucha is certainly possible it’s extremely rare (and not recommended).

It’s also worth noting that while the original batch of kombucha is often made with a significant amount of sugar, this sugar is almost entirely burned off during the fermentation process, leaving kombucha naturally low in sugar and a great alternative to soda and other bottled teas and lemonades.

Be wary of kombucha that lists more than 5 grams of sugar, or any additional added ingredients, particularly those you may not recognize or that may be difficult to pronounce. These are likely added after the fermentation process and can dilute the real health benefits of the kombucha.

You Can Drink Too Much Kombucha

Kombucha is rich in lactic acid believed to cause lactic acidosis in some people. Lactic acidosis is a result of excess lactic acid in the bloodstream that can be life-threatening. However, if you’re not drinking multiple bottles of kombucha a day, then you should be okay. It is always recommended to consult with your physician before consuming any new products intended to promote positive health benefits.

Kombucha Is Not a Caffeine Replacement

While it is made from tea, kombucha does not contain a significant amount of caffeine; in fact, it’s pretty low. Most store-bought kombucha contains anywhere from 2 to 25 mg of caffeine, which is far less than the amount of caffeine found in a cup of coffee (95 mg). However, if you do have caffeine sensitivities, consider other drink alternatives as there is indeed enough to affect you.

Drinking Kombucha

It’s no question that the health benefits of kombucha are worth exploring. Start by trying out a few different brands or asking your grocer for recommendations. You can also sometimes find fresh brewed kombucha at your local health food stores, restaurants, and cafes.

If, however, the taste is still displeasing, or if you’re interested in switching up your kombucha delivery method, check out this delicious Kombucha Smoothie Bowl as an alternative. It contains bananas, berries, and heart-healthy coconut oil, making it a sweeter and, in some ways, an easier kombucha to swallow.
