Yogurt, particularly those containing probiotics, may help in preventing urinary tract infections (UTIs) by promoting a healthy balance of bacteria in the body. However, yogurt is not a substitute for proper medical treatment for UTIs.
Key facts:
Yogurt is a good source of probiotics (may prevent UTIs).
Yogurt is not a substitute for UTI treatments.
Yogurt can boost your immune system to fight bacteria.
Probiotic-rich yogurt may decrease your risk of recurrent UTIs.
Choose live-culture yogurts with proper strains.
Beware of sweetened yogurt and lactose intolerance.
1. Yogurt is a good source of probiotics (may prevent UTIs).
Yogurt is made by fermenting milk using specific bacteria, which can produce beneficial microorganisms called probiotics.
These probiotics, particularly Lactobacillus strains, have been studied for their potential role in preventing UTIs.
They may help maintain a healthy balance of bacteria in the urogenital tract, preventing harmful bacteria from causing infections.
The role of probiotic-containing yogurt (and probiotics in general) is yet to be established.
Several studies have been carried out to determine its effectiveness; for example, a 2018 study concluded that yogurt that contains certain lactobacillus bacteria strains (lactobacillus paracasei N1115) decreased the risk of getting UTI by about 45%.
Other studies about the role of probiotics (the active component in yogurt) in UTI prevention are enlisted in the table below.
No significant benefit was found for probiotics in UTI prevention; limited data from small, poorly reported studies.
2. Yogurt is not a substitute for UTI treatments.
While yogurt containing probiotics may help prevent UTIs, it should not be considered a substitute for proper medical treatment.
UTIs require antibiotics to eliminate the infection-causing bacteria. If you suspect you have a UTI, consult your healthcare provider for appropriate diagnosis and treatment.
Until now, no diet or supplement can treat UTI without antibiotics. So, use such remedies as support to treatment or for prevention (although their role is not fully established).
3. Yogurt can boost your immune system to fight bacteria.
Probiotics in yogurt can support your immune system by stimulating the production of immune cells and enhancing their function.
A strong immune system can help your body fight off harmful bacteria, potentially reducing the risk of UTIs.
Probiotics in yogurt maintain a healthy gut microbiota, which is crucial for immune function.
Probiotic interaction with immune cells stimulates the production and activation of these cells.
Some probiotics exhibit anti-inflammatory properties, regulating the immune system.
Yogurt contains essential nutrients (protein, vitamins, minerals) that support immune system function.
4. Probiotic-rich yogurt may decrease your risk of recurrent UTI.
Studies have shown that certain probiotic strains, such as Lactobacillus rhamnosus and Lactobacillus reuteri, may be effective in preventing recurrent UTIs in women. Consuming yogurt with these specific strains might help reduce the risk of UTI recurrence. However, more research is needed before recommending probiotic-rich yogurt as a preventive measure for everyone.
5. Choose live-culture yogurts with proper strains.
Not all yogurts contain active cultures. While traditional yogurt is made using active cultures, some commercial yogurt brands may not contain live and active cultures or a limited number of strains.
To determine whether a yogurt contains active cultures, look for the “live and active cultures” seal on the packaging. This seal indicates that the yogurt meets the National Yogurt Association’s criteria for containing at least 100 million cultures per gram at the time of manufacture.
It’s also important to note that some yogurts may contain added sugars, flavorings, and other ingredients that can reduce the health benefits of active cultures. To get the most health benefits from yogurt, choose plain, unsweetened yogurt containing active cultures and add your toppings, such as fresh fruit, nuts, or honey.
6. Beware of sweetened yogurt and lactose intolerance.
Sweetened yogurts can contain high amounts of sugar, which can not only negate the potential health benefits of yogurt but also contribute to weight gain and other health issues. Opt for unsweetened yogurt and add natural sweeteners like fruit or honey if needed.
Additionally, some people may be lactose intolerant and unable to digest the lactose found in yogurt. In such cases, consumption of yogurt may lead to gastrointestinal discomfort. If you’re lactose intolerant, consider trying lactose-free yogurt alternatives.
7. My opinion: Probiotic supplements are better than yogurt for UTI.
As a kidney doctor, I always advise patients with recurrent UTIs (rUTIs) to add a probiotic for protection.
Despite being a good source of probiotics, probiotic is not as good as probiotic supplements.
Here is why probiotic supplements are a better option than yogurt:
Specificity: Probiotic supplements contain targeted strains for UTI prevention.
Higher concentration: Supplements offer higher concentrations of beneficial bacteria.
Controlled dosage: Supplements provide consistent and controlled dosages.
Less risk of Lactose intolerance and dietary restrictions: Supplements can be lactose-free and suitable for various diets.
Less added sugar: Supplements typically lack added sugars, unlike some yogurts. Even unsweetened yogurt contain lactose (the main sugar in dairy), which can add to your overall calories.
FAQs:
Is Activia yogurt good for UTI?
Activia is a brand of yogurt that contains a specific probiotic strain called Bifidobacterium animalis lactis DN-173 010. While this strain has been shown to improve digestive health, its effectiveness in preventing or treating UTIs is not well-established. For UTI prevention, focus on yogurts with strains like Lactobacillus rhamnosus and Lactobacillus reuteri.
What yogurt is good for UTI?
Yogurt containing specific probiotic strains, such as Lactobacillus rhamnosus and Lactobacillus reuteri, may be beneficial for preventing UTIs. Look for yogurt with the “live and active cultures” seal and choose plain, unsweetened varieties to maximize health benefits.
Is Greek yogurt good for UTI?
Greek yogurt, like regular yogurt, can be a good source of probiotics if it contains live and active cultures. The straining process of making Greek yogurt results in a thicker, creamier texture and higher protein content. As long as it contains the right probiotic strains and minimal added sugars, Greek yogurt can be a healthy choice for UTI prevention.
