Dietary Choices Impact Oral Microbiome and Overall Health
Translated & summarized from Vesty by baba
A Ynet article highlights how the oral microbiome, influenced by diet, impacts overall health. Beneficial bacteria thrive on nitrates found in vegetables, while sugar feeds cavity-causing bacteria. Hard cheeses and fermented foods support oral health, whereas processed carbs and red meat can be detrimental. Dr. Sagi Levin advises against harsh mouthwashes, stressing the importance of brushing, flossing, and a balanced diet for maintaining beneficial oral bacteria and systemic well-being.

- Dietary choices significantly impact the oral microbiome, affecting dental and overall health.
- Nitrate-rich vegetables like beets and spinach support beneficial oral bacteria by raising pH.
- Hard cheeses and fermented foods like kefir promote saliva and beneficial bacteria, aiding oral health.
- Processed, starchy foods and red meat can negatively affect the oral microbiome and gum health.
- Dr. Sagi Levin advises against alcohol-based mouthwashes, recommending brushing, flossing, and a diverse diet.
The balance of bacteria in the mouth, known as the oral microbiome, affects not only dental health but also the entire body, according to an article on Ynet. While around 700 species of bacteria, along with viruses and fungi, inhabit the mouth, the focus is shifting from identifying specific harmful bacteria to understanding the overall microbial balance and its interaction with the immune system. For instance, Streptococcus mutans, linked to cavities, thrives on sugars, producing acids that erode tooth enamel. Conversely, beneficial bacteria like Streptococcus salivarius and Streptococcus sanguinis compete with harmful ones and can produce substances that inhibit pathogens. Imbalances can lead to deep pockets between gums and teeth, fostering bacteria like Porphyromonas gingivalis, which can cause severe gum inflammation and bone loss.
The oral microbiome's health is increasingly linked to systemic conditions. Research suggests connections between gum disease and an elevated risk of cardiovascular disease, Alzheimer's, diabetes complications, arthritis, inflammatory bowel disease, premature birth, and certain cancers, including pancreatic and colorectal cancer. Some studies also indicate a link between reduced oral bacterial diversity and depression.
Diet plays a crucial role in maintaining this balance. Foods rich in inorganic nitrates, such as spinach, arugula, kale, and beets, can be converted by beneficial bacteria into nitrites, raising oral pH and inhibiting harmful bacteria. Beetroot juice, for example, has been shown to lower blood pressure. Polyphenol-rich foods like green and black tea, dark berries, and cranberries can inhibit odor-causing bacteria and prevent plaque formation. Hard cheeses like Parmesan and cheddar stimulate saliva production, which washes away sugar and neutralizes acids, while their casein and calcium content strengthen enamel. Fermented foods like kefir and yogurt promote beneficial bacteria, though their effectiveness in the mouth can vary.
Conversely, processed, starchy foods that stick to teeth, such as crackers, cookies, and white bread, can prolong acidity and promote cavity-causing bacteria. Frequent consumption of red meat has also been associated with more severe gum disease, possibly due to protein creating a favorable environment for anaerobic bacteria.
Dr. Sagi Levin from Ichilov Hospital's dentistry department cautions against overreliance on antibacterial mouthwashes, especially those with high alcohol content, which can dry out the mouth and potentially lead to the formation of carcinogenic acetaldehyde. Medicated mouthwashes with chlorhexidine are intended for short-term use. For daily oral hygiene, Dr. Levin recommends proper brushing, flossing, and interdental brushes, emphasizing that a diverse diet is paramount for supporting beneficial bacteria and overall health.
