  • One of the main causes of bad breath, also known as halitosis, is the buildup of volatile sulfate compounds in the mouth produced by anaerobic bacteria that eat leftover food.
  • A new meta-analysis found that intake of four probiotics can reduce compounds that cause bad breath, at least in the short term.
  • 4 Beneficial Probiotics Are Lactobacillus salivarius, Reuteri bacteria, Streptococcus salivariusWhen Weissella Sibaria, all of which can benefit gut health. They are found in fermented foods.

There are many possible causes of persistent bad breath and bad breath, but one of the main factors is poor dental hygiene.

A recent meta-analysis suggests that certain probiotics can address one of the main causes of bad breath. has been shown to help eliminate the buildup of biofilm.

The author of the analysis report is Lactobacillus salivarius, Reuteri bacteria, Streptococcus salivariusWhen Weissella Sibariacontained in fermented foodsReduces volatile sulfates for up to 4 weeks compared to controls.

The results of this study were recently BMJ Open.

To conduct the meta-analysis, researchers examined the results of seven randomized controlled trials (RTCs) involving 278 participants.

The number of participants in each study varied from 23 to 68, and the age of individuals ranged from 19 to 70 years.

Each study was analyzed to measure halitosis subjectively and objectively over a period of up to 12 weeks.

Researchers detected halitosis levels from participants who closed their mouths for 1 minute before exhaling into the rater’s nose from a distance of 10 centimeters. A sensory-based sensory score (OLP) was generated.

Volatile sulfate compounds (VSCs) were then measured objectively using a halimator, an instrument that detects and measures the presence of gases.

VSCs are produced by anaerobic bacteria that interact with leftover food in the mouth due to poor dental hygiene.

Michelle Routhenstein, MS, RD, CDE, CDN, Cardiology Dietitian at explained: medical news today:

“Certain bacteria live in your mouth and break down food, leading to the production and release of volatile sulfate compounds that cause bad breath. The bacteria most associated with bad breath are: Gram-negative bacteria

A new study has identified four beneficial probiotics, including Gram-positive bacteria.

Such bacteria “change the oral microbiome to reduce the accumulation of these volatile sulfates,” explained Routhenstein.

The authors of the current study cites growing evidence that probiotics can keep out the bacteria involved in breaking down amino acids and proteins.

The findings show that bad breath was significantly reduced according to both measurement methods they used.

The OLP score was reduced by 58% and the VSC score by 26% compared to the control group.

However, according to VSC scores, the positive effects of probiotics were not sustained beyond 4 weeks. However, improvements in OLP scores were maintained beyond 4 weeks.

The analysis also found that probiotics did not address plaque buildup and tongue coating, two other major causes of bad breath. Some beneficial effects have been shown.

As a meta-study, the authors note weaknesses in the original study that should be considered as limitations of the meta-analysis.

There were significant differences between studies with respect to methodology, reported data, and risk of bias in assessment.

To control bad breath, you can try a variety of remedies, such as scaling your teeth, scrubbing your tongue, and using mouthwash.

Others may try to improve their breath by chewing gum, but this may not be the most effective option in the long run.

“When you chew, you prepare your body to trigger stomach acid and digestive enzymes. When food doesn’t come in, you prepare for GERD. [or] Acid reflux and dental problems are on the rise,” said Lyn-Genet Recitas, nutrition expert and bestselling author of “The Plan” and “The Metabolism Plan.” MNT.

“Oral health, or lack thereof, is associated with many ailments, including rheumatoid arthritis, diabetes, respiratory disease and even heart disease.”

The authors of this study suggest that probiotics may improve oral health by fighting bad breath.

Probiotics are organisms, beneficial bacteria and yeasts that occur naturally in the human body. They may be consumed as supplements or in food.

Both methods can provide benefits, but a 2016 meta-analysis found that consuming probiotics in food sources may be the best way to get them. rice field.

To reap the benefits of probiotics Lactobacillus salivarius, Reuteri bacteriaWhen Streptococcus salivariusRouthenstein recommends fermented foods such as yogurt, kefir, kimchi and pickled beets.

“Consuming a variety of probiotic-rich foods may benefit not only the oral microbiome, but also the gut microbiome, which is particularly important for overall health and heart health. I have.

Recitas added that miso and real sauerkraut, fermented cheese and sourdough bread are other good food sources of probiotics. Weissella cibariais The bacteria in these foods ferment the food.
