A diet high in fruits, vegetables, and whole grains allows beneficial bacteria to dominate and inhibits the growth of harmful strains. Here are some general tips for helping microbes in our body, however more research is needed on what the optimal solution is:
- Focus on fruits and vegetables: A plant based diet rich in vegetables, fruit, legumes and high in dietary fiber and polyphenols seems to help the microbiota. These foods offer prebiotics.
- Fermented foods may affect microbiota by influencing the gene expression of the bacteria that already exists. Yogurt and kefir are both naturally fermented foods with live active cultures and sauerkraut, kimchi, tempeh, and raw vinegar are high in Lactobacillus bacteria.
- Garlic and leeks contain natural sources of prebiotic inulin.
- Focus on minimum processed foods and limit sugar and unhealthy fats.
- Consider taking a probiotic supplement (L. acidophilus, L. reuteri, B. longum and B. bifidium) — during and after antibiotic use to help manage antibiotic-induced diarrhea. Antibiotics kill all bacteria (good and bad!), so it is helpful to take probiotic supplements two hours before or after taking antibiotics.
