Numerous studies suggest that specific foods and drinks, including soda, might elevate the risk of developing a urinary tract infection (UTI). Nevertheless, further research is essential to thoroughly investigate the relationship between dietary habits and the incidence of UTIs. It is widely acknowledged that your dietary choices can influence your vulnerability to urinary tract infections. Many online resources advocate for the avoidance of particular foods and drinks while promoting the consumption of others to effectively manage and prevent recurrent UTIs. Yet, a significant portion of these suggestions lacks robust scientific backing, leading many individuals to wonder if any particular dietary patterns or specific foods can genuinely prevent or treat UTIs. This article delves into the role of your diet in the onset of UTIs and proposes evidence-based lifestyle and dietary changes that may assist in preventing and managing these infections.

Can Diet Play a Role in Preventing or Treating UTIs?

Despite numerous claims on various websites regarding the impact of diet on urinary tract infections (UTIs), substantial scientific evidence supporting this connection remains elusive. While some studies indicate that certain beverages and dietary habits might heighten the risk of developing UTIs, research specifically examining how diet influences this risk, or if particular foods and drinks can mitigate the duration or severity of a UTI, is quite limited.

Interestingly, research findings suggest that both dietary choices and fluid consumption are not regarded as independent risk factors for the onset of UTIs. Nevertheless, the current body of research exploring the relationship between dietary patterns and the likelihood of developing a UTI points to some intriguing possibilities.

In summary, while the evidence linking diet to UTIs is not robust, it is important to acknowledge that some studies hint at the potential for certain dietary habits to offer protection against these infections. The forthcoming section will delve into the specific dietary patterns, foods, and beverages that might influence UTI risk.

Can Your Diet Influence the Risk of UTIs?

Emerging research indicates that specific dietary habits could potentially offer protection against urinary tract infections (UTIs). Conversely, certain foods and drinks may increase the likelihood of developing these infections.

Benefits of Vegetarian Diets

Several studies have pointed towards a correlation between vegetarian diets and a diminished risk of UTIs. For instance, a comprehensive 2020 study involving 9,724 Buddhists over a span of 9 years revealed that those adhering to a vegetarian dietary pattern experienced a remarkable 16% reduction in the risk of developing a UTI, particularly evident among women.

Investigators have hypothesized that specific foods, such as chicken (??????) and pork (???? ?? ????), may serve as “food reservoirs” for certain strains of the bacterium E. coli, notably the extraintestinal pathogenic E. coli (ExPEC), responsible for 65–75% of all UTIs. This implies that these food reservoirs could facilitate the transmission of ExPEC. The researchers from the 2020 study proposed that by avoiding common food reservoirs of ExPEC, individuals following vegetarian dietary patterns might gain a protective advantage against UTIs.

Moreover, vegetarian diets might help in reducing UTI risks by making urine less acidic. Studies have indicated that when urine maintains a more neutral pH, it hinders the growth of bacteria linked to UTIs. On the contrary, red meat and various animal proteins are known for their high potential renal acid loads (PRALs), which contribute to increased acidity in urine. In stark contrast, fruits and vegetables boast low PRALs, thereby helping to maintain a less acidic environment. These considerations could elucidate why vegetarian diets may offer a protective effect against UTIs. However, further investigation into this potential benefit is warranted.

In summary, there is emerging evidence that vegetarian diets may shield individuals from UTIs, primarily due to the role of certain foods, such as pork, as significant “food reservoirs” for bacterial strains of E. coli, which are responsible for the majority of these infections.

Beverages that may influence UTI risk

Research has established a notable connection between the intake of specific beverages and urinary tract infections (UTIs). Old studies have indicated that the consumption of soda may correlate with recurrent instances of UTIs. An investigation from 1985 involving 225 women revealed a strong association between the intake of cola soft drinks and UTI occurrences.

Furthermore, several studies have indicated that particular beverages may irritate the bladder and are linked to lower urinary tract symptoms. In a study conducted with 30 women, it was found that reducing the intake of potentially irritating foods and drinks, including coffee, tea, alcohol, and carbonated or artificially sweetened beverages, led to a decrease in lower urinary tract symptoms, such as urgency and frequency of urination.

Nonetheless, the researchers could not ascertain whether the alleviation of symptoms resulted from the reduction of one or all of the irritating beverages. Another study encompassing 4,145 adults also identified a correlation between the consumption of coffee and soda and infections affecting the lower urinary tract.

On the flip side, some research has suggested that certain foods and beverages might help lower the risk of developing UTIs. A 2003 study involving 324 women found a significant association between frequent consumption of freshly squeezed, 100% juice—particularly berry juice—and fermented dairy products like yogurt, with a reduced occurrence of UTIs. The previously mentioned 4,145 participant study also indicated that citrus juice intake was linked to a 50% decline in lower urinary tract symptoms, but this was specifically noted in men. Additionally, an increase in water consumption may aid in lowering UTI incidences among certain groups.

A 2019 study focused on older adults residing in nursing homes showed that enhancing hydration to meet the daily fluid intake recommendation of 6–8 glasses of water could lower the requirement for antibiotics by 58% and decrease hospitalizations due to UTIs by 36%. Another investigation involving 140 women with recurrent UTIs, who initially consumed less than 1.5 liters (51 ounces) of water daily, found that increasing their daily water intake by an additional 1.5 liters (51 ounces) over a year significantly protected against recurrent UTIs in comparison to those who did not boost their intake. While increasing water intake appears to be a viable strategy for reducing UTI occurrences in certain populations, further studies exploring this potential connection are essential, as many existing studies on the topic are dated.

Potential bladder irritants

During a UTI, it is advisable to steer clear of beverages that may irritate the bladder, such as coffee, tea, soda, alcohol, and artificially sweetened drinks like diet sodas, as this may alleviate symptoms. Additionally, some research indicates that certain foods and drinks, including spicy peppers, alcohol, tea, soda, artificial sweeteners, and certain fruits and juices, could exacerbate symptoms associated with bladder-related conditions like bladder pain syndrome/interstitial cystitis (BPS/IC).

However, it is important to note that these conditions are separate from UTIs. Although it seems logical to eliminate these foods and drinks for potential relief, current evidence does not strongly support the idea that avoiding specific foods or beverages will cure or significantly diminish UTI symptoms.

Furthermore, this article does not delve into supplements related to UTI prevention or treatment. Research suggests that certain supplements, such as probiotics and cranberry, may assist in preventing and addressing UTIs. Ultimately, consuming soda and coffee may elevate your UTI risk and irritate your bladder, whereas staying well-hydrated and indulging in freshly squeezed juice and fermented dairy could aid in reducing the risk of UTIs.

Lifestyle Recommendations

In addition to exploring the dietary suggestions mentioned earlier, implementing certain lifestyle changes can significantly lower your risk of developing a urinary tract infection (UTI).

Several risk factors are associated with the likelihood of UTI occurrence, including:

  • having a compromised immune system
  • engaging in sexual intercourse four or more times weekly
  • deficiency in estrogen levels
  • anatomical irregularities in the urogenital tract
  • dysfunction of the bladder
  • new sexual partners and the use of spermicides, which may alter vaginal pH
  • a family history of UTIs or experiencing them during childhood
  • possessing a non-secretor blood type, meaning your blood group antigens are absent in bodily fluids such as tears, saliva, urine, or breast milk
  • fluctuations in bacterial flora

Other factors believed to elevate your chances of developing a UTI include the wearing of tight-fitting underwear, using hot tubs, failing to urinate post-intercourse, and douching; however, substantial evidence supporting these claims is currently lacking. While it may not be possible to change some of these factors, if you suffer from recurrent UTIs, it’s advisable to steer clear of controllable risk factors and consider making specific dietary and lifestyle adjustments that may be beneficial. It is important to note that there is no strong evidence indicating that any particular foods or beverages can effectively treat or prevent UTIs.

Additionally, seeking advice from a healthcare professional is crucial if you experience frequent UTIs to receive appropriate treatment. Untreated infections can lead to severe complications, such as urosepsis, a potentially life-threatening condition.

Implementing certain lifestyle changes may aid in reducing both the occurrence and symptoms of UTIs. Nonetheless, consulting a healthcare professional is recommended for those who frequently experience UTIs, as leaving such infections untreated can result in dangerous complications.

The Bottom Line

While some research indicates that specific dietary adjustments might lower the risk of urinary tract infections (UTIs) and alleviate certain bladder-related symptoms, the current body of research in this domain is relatively insufficient. Adopting a vegetarian diet, increasing your fluid consumption, and eliminating potential bladder irritants such as soda, alcohol, artificial sweeteners, and coffee from your meals may assist in preventing UTIs and mitigating symptoms. For instance, in India, traditional beverages like coconut water and chaas (buttermilk) are often recommended for hydration. In Australia, there is a growing trend towards plant-based diets which align with these findings. Nonetheless, further studies delving into the relationship between dietary habits and UTIs are essential to establish firmer conclusions. If you experience frequent bladder infections, it is crucial to consult a healthcare professional who can provide appropriate treatment and guidance. They are equipped to help you feel better and avert complications related to UTIs.
