Kombucha is a fermented tea that has been consumed for thousands of years.
Not only does it have the same health benefits as tea — it's also rich in beneficial probiotics.
Kombucha also contains antioxidants, can kill harmful bacteria and may help fight several diseases.
Here are the top 8 health benefits of kombucha, based on scientific evidence.
Kombucha is thought to originate in China or Japan.
It's made by adding specific strains of bacteria, yeast and sugar to black or green tea, then allowing it to ferment for a week or more (1).
During this process, bacteria and yeast form a mushroom-like film on the surface of the liquid. This is why kombucha is also known as "mushroom tea."
This blob is a living symbiotic colony of bacteria and yeast, or a SCOBY, and can be used to ferment new kombucha.
The fermentation process produces acetic acid (also found in vinegar) and several other acidic compounds, trace levels of alcohol and gases that make it carbonated (2).
A large amount of bacteria also grow in the mixture. Although there is still no evidence for the probiotic benefits of kombucha, it contains several species of lactic-acid bacteria which may have probiotic function. (3).
Probiotics provide your gut with healthy bacteria. These bacteria can improve many aspects of health, including digestion, inflammation and even weight loss.
For this reason, adding beverages like kombucha to your diet might improve your health in many ways.
Summary Kombucha is a type of tea that has been fermented. This makes it a good source of probiotics, which have many health benefits.
Green tea is one of the healthiest beverages on the planet.
This is because green tea contains many bioactive compounds, such as polyphenols, which function as powerful antioxidants in the body (4).
Kombucha made from green tea contains many of the same plant compounds and presumably boasts some of the same benefits (5).
Studies show that drinking green tea regularly can increase the number of calories you burn, reduce belly fat, improve cholesterol levels, help with blood sugar control and more (6, 7, 8, 9).
Studies also show that green tea drinkers have a reduced risk of prostate, breast and colon cancers (10, 11, 12).
Summary Kombucha made from green tea may offer many of the same health benefits as green tea itself, such as weight loss and blood sugar control.
When is yogurt good for you?
Whether yogurt is a healthful choice depends on the person consuming it and the type of yogurt.
Yogurts can be high in protein, calcium, vitamins, and live culture, or probiotics, which can enhance the gut microbiota.
These can offer protection for bones and teeth and help prevent digestive problems.
Low-fat yogurt can be a useful source of protein on a weight-loss diet.
Probiotics may boost the immune system.
Some argue that they could also impact brain functioning, too, although more research is necessary to confirm some of these claims.
In 2014, researchers found that consuming yogurt may help protect against type 2 diabetes. Other types of dairy product did not appear to impact the likelihood of developing the condition.
Other scientists have suggested that yogurt containing probiotic bacteria successfully protects children and pregnant women against the effects of heavy metal exposure.
It is also a nutritious option when people find it difficult to chew their food.
Non-dairy yogurts offer an alternative for people who do not consume dairy or animal products or have allergies or intolerances.
Yogurt contains less lactose than milk because the lactose is used up in the fermentation process.
Not all yogurts are healthful. Those without added sugar or unnecessary additives can be a healthful addition to the diet, but some products have high quantities of added sugar and other ingredients that may not be beneficial.
Natural yogurt can be a low-calorie, high-nutrient food packed with protein.
However, many manufacturers add sugar, artificial sweeteners, and other ingredients that are not healthful.
All yogurts contain some natural sugars, but consumers are advised to look for a product with less than 15 grams of sugar per serving. The lower the sugar, the better, as long as it does not contain any artificial sweeteners.
Some studies have refuted the view that yogurt consumption is linked to good health, causing authorities to question whether health claims can be made for commercial purposes. However, people who eat yogurt are more likely to have an otherwise healthy diet.
Packaged products like cereals and bars claiming to be "made with real yogurt," yogurt-covered raisins and other products with yogurt coating contain only a small amount of yogurt powder.
Yogurt powder is heat-treated, and heat kills the beneficial bacteria. Yogurt coatings are made of sugar, oil, whey, and yogurt powder.
