Functional Nutrition and Lifestyle Strategies to Promote Microbiome Health During & After Antibiotic Therapy

Weight loss help. Professional weight loss program by Biljana Sofronijoska-Rece

Since the discovery of penicillin in the 1920`s, countless lives have been saved in fight with bacterial infections. Their use continues to be crucial in modern day medicine, and their role remains to be of utmost importance. More and more research studies continue to evaluate possibility of adverse events and negative impact this mode of therapy might  have on our overall gut health & microbiome diversity, it`s correlations with chronic disease when proper nutrition and lifestyle strategies are not being used hand in hand during and post their administration.

In 2018, the Federation of European Microbiological Societies (FEMS) reported administration of antibiotics to over 10% of European children, and accounted 25% antibiotic prescriptions to the pediatric population in USA per 2008 retrospective cohort study review(1). They also included a review of the effects of antibiotics on microbiome in children, correlating them to long lasting complications of obesity, behavior and neuro-development, allergies, autoimmunity, IBD, and weight gain.

Multiple studies have demonstrated the ability of antibiotic treatment to alter both infant and adult microbiome composition causing microbial imbalance known as dysbiosis, which in turn is correlated with impaired health and chronic inflammatory diseases if systematically left untreated. In a 2011 Nature Review Microbiology, looking at “how host genetics and environment shape the gut microbiota and how all of them may interact in the context of chronic disease”, are noted multiple disorders associated with altered gut microbiome.(4) The list includes, but is not limited to: IBS, IBD, gallstones, Colorectal Cancer, recurrent C.Diff infections, arthritis, asthma, autoimmune disorders, diabetes, eczema, metabolic syndrome, mood disorders, multiple sclerosis, obesity, etc. Hippocrates words” All diseases begin in the gut” might hold great truth after all.

Insight into what happens to gut microbiome after antibiotic therapy was published by Palleja et al in 2018. They followed 12 healthy adults over 6 month time period, after 4 day intervention with a cocktail of 3 antibiotics, commonly used in ICU (meropenem, gentamicin and vancomycin). (3) At ~ 45 days, shotgun sequencing –based metagenomics analysis showed gut microbiota has recovered near base line composition. At 6 month mark, 9 common species which were present in all subjects prior to the treatment remained undetectable. Study results confirm the hypothesis that broad spectrum antibiotics may alter the diversity and richness of gut microbiome. It is poor diversity, decrease in beneficial species, and subsequent increase in pathogenic ones that is associated with obesity, certain autoimmune conditions, metabolic disorders, and overall poor health. Even though researchers described the ability of antibiotic exposure to effect the gut microbiota of healthy young adults as“mild, yet long lasting imprint”, and noted the resilience of gut microbiome to regenerate, however, one might agree with the concern of what happens to the diversity and richness of our gut microbiome, after MULTIPLE exposures to antibiotics we might endure during our lifetime, and how that affects our overall health and well being and how is correlated to chronic disease?

The role and effect of probiotic intake during antibiotic therapy was published by Wieërs, Grégoire et al in 2021 in a randomized placebo controlled trial of 120 patients ,age median of 78 years old, with multiple co- morbidities. More specifically, they were looking whether probiotic intake during in-hospital antibiotic treatment will prevent colonization of gut microbiota with multi-drug-resistant bacteria. They were treated for 10 days with amoxicillin-clavulanate antibiotics comparing the effects of a 30 days treatment with placebo Saccharomyces boulardii and a probiotic mixture containing S. boulardii, L. acidophilusL.paracasei,  and B.lactis . Treatment was initiated within 48 hrs  within antibiotic administration. Stool samples were collected at the time of the inclusion of the trial, at the end of the antibiotic treatment and at the end of the study treatment. Results showed that taking probiotic mixture containing strains of  S. Boulardi combined with Lacto and Bifidobacterium “influenced the antibiotic treatment by counteracting the colonization of the colon microbiota with antibiotic- resistant pathogens”.(2)

This research study relays good news regarding gut health maintenance and antibiotic therapy.  Simply by incorporating probiotics with antibiotic therapy to assure integrity and maintenance of gut microbiome, and I would add from functional nutrition perspective, incorporating food and lifestyle practices to continue to feed and support diversity of gut microbiome would be an overall win-win scenario, in which one can enjoy the benefits and the therapeutic reason of antibiotic administration while protecting gut integrity. Following guidelines and nutrition recommendations sometimes tends to feel like a full time job which is quite easy to be non-compliant with. And so, how I like to remember and try to make it as a lifestyle pattern rather than a job to do would be by asking myself 3 questions, for there is no such thing as one intervention to fit and fix everything:

  1. Did I feed my gut today by recalling 3 P`s + S meaning Pre-Probiotic and Polyphenol rich foods + Soluble fiber.
  2. Did I avoid simple sugars?
  3. Did I invest time in self care?

Prebiotic & Probiotic rich foods -> aid in microbiome health and maintenance.

  • Fermented anything: kefir, yogurt, fermented vegetables such as cabbage, pickles, red bell peppers, green tomatoes massively used in Mediterranean cuisine. When opting to purchase fermented vegetables, please start practicing reading labels, and do your best to buy real foods with minimal to none preservative ingredients with names that are hard to pronounce. Remember regarding food choices, simple is better, variety and color even more so, modesty is the key
  • Allium Vegetable family: garlic, onion, leeks and chives. Using them in soup is a good strategy.
  • Green Color vegetables: asparagus, Jerusalem artichoke, peas, soybeans
  • Legumes->bean, peas, chickpea, lentil, peanut and soybean.
  • Fruits-> such as bananas, apples, and berries
  • Honey-> prebiotic(food) for beneficial strains due to prebiotic oligiosacharides and antibacterial components, which when ingested with a probiotic strains synergistically enhance the probiotic strain efficacy against pathogens.(11)

Oral probiotic-> look for mixture containing strains of  S. Boulardi combined with Lacto and Bifidobacterium. Given that supplement industry is not heavily regulated, on more tips and guidance on how to pick clean and safe supplements refer to another informative read ” The ultimate guide to buying safe supplements” article on ProjectofHealth.com

Polyphenols-> bioactive compounds found in colorful plant foods. Once ingested, depending on the degree of structural complexity and polymerization, may be readily absorbed in small intestine (5-10 %), or accumulated in large intestinal lumen where are subjugated to enzymatic activities of gut microbial community for extensive breakdown to metabolites which might be responsible for the health effects from colorful rich foods.(7) Researchers conclude “dietary polyphenols and their metabolites contribute to the maintenance of gut health by modulation of gut microbial balance through stimulation of growth of beneficial bacteria and inhibition of pathogen bacteria, exerting prebiotic-like effects.”

  • Epigallocathechin-3-gallate (EGCG) -> sensitizes methicillin resistant Saureus(MRSA)to beta-lactam antibiotics; increases cell wall thickness; may alter bacterial cell wall and inhibit  bacterial cell growth. Food Sources: Green Tea, Matcha Tea, berries, grapes, red wine, chocolate and apples
  • Resveratrol-> promotes growth of Bifidobacterium and shifts microbiome growth towards beneficial species. Found in skin of red grapes, tea, berries, pomegranates, nuts (peanuts, almonds), blueberries, and dark chocolate.
  • Quercitine: -> inhibits DNA & RNA bacterial synthesis. Food sources: apples, onion, broccoli, kale, green beans, broccoli, alfalfa sprouts, apples, apricots, berries, nuts, seeds, tea, wine, cocoa.

Soluble Fiber -> Increases beneficial SCFA’s (short chain fatty acids) known for their role in strengthening gut barrier, gut motility, immune-modulator role as well as being fuel for intestinal epithelial cells. (5) Food sources: oat bran, barley, nuts, seeds, beans, lentil, citrus fruits, berries, apples.

Avoid-> Simple Sugars: Recent 2020 study looking at mechanisms underlying the pro-inflammatory effect of dietary fructose showed that it is due to “changes in composition microbiota and metabolic function of resident enteric microbiota”.(6)Regarding food sources, my rule of thumb is: if it comes in a box or plastic bottle and has a vibrant beautiful artificial color, or is as white  as a sugar cube, it is a no no, for that is a route down a rabbit hole I truly do not want to partake.

Practice Self Care Daily: Lifestyle as Medicine: the reality of modern industrial times is the fact that we must put effort into strategies for self care that includes basic human practices that we have learned to sacrifice in order to keep up. And so, adequate Sleep; Movement and Physical Activity 30 min/5 days /week;  Stress-> coping; stress relief techniques such as breathing, singing, walking in nature etc would be some very common ones that we have taken granted for. For all these lifestyle modifications if not practiced, have been found not to only alter gut composition, but also play role in inflammation, immunity resilience, and pro-inflammatory cytokine production via multiple mechanisms.
