Power Up Your Gut with Fermented Foods

Fermented foods may be setting trends on The Huffington Post, but these nutrient-potent foods have been around for thousands of years in Japanese, Chinese, Indian, and German cultures. For people living without modern medicine and refrigeration, fermentation was a simple means of food preservation and a way to imbue foods with the health-enhancing properties of the live bacteria the gut needs to stay in balance. Fermented foods are a potent source of probiotics, which research has shown are essential to powering up the mucosal immune system in your digestive tract and producing antibodies to pathogens. Both are key to helping you maintain vibrant health.

You may not even realize just how many fermented foods you already enjoy in your diet (see list). Incorporate more of these probiotic powerhouses into meals, and put those good-for-you organisms back into action in your gut.

Fermented Foods Short List

• Cultured Dairy: Yogurt, kefir, buttermilk, sour cream, some cheeses
• Veggies: Beets, radishes, tomatoes, onions, garlic, kimchi, green beans, sauerkraut
• Condiments fermented at home or commercially: ketchup, relish, salsa, chutney
• Other: Miso, tempeh, tofu, soy sauce

Fermented Food Facts & Tips

• All fermented foods must be kept cool to maintain the live cultures.
• Food labels must be marked "fermented."
• Fermented and "pasteurized" do not go together. Pasteurization kills live cultures.
• Pickled is not the same as fermented (unless indicated on the label). Pickled foods are soaked in vinegar or brine.
• Choose organic, non-GMO items or locally farmed products.
• Start with small servings of fermented foods, one to two times a day.
• Toss fermented veggies into salads; enjoy as a snack or as a side dish.
• Add a spoonful or two to your morning smoothie (e.g., beets, kefir).

Probiotics

With 80% of your immune system located in your gut, having balanced intestinal flora is a major factor in defending your body against disease. Balanced gastrointestinal (GI) flora is critical to the functioning of the immune system, synthesis of nutrients, and detoxification. Balanced GI flora is also necessary for regular and normal bowel movements.

Flora imbalances can be caused by poor diet, illness, use of antibiotics, and stress.  Symptoms can include persistent gas, bloating, constipation, or diarrhea. To maintain or rebalance GI flora, consider adding probiotics to your diet.

Probiotics are live microorganisms (in most cases, bacteria) that are similar to the beneficial microorganisms naturally found in your GI tract. The most common probiotic bacteria come from two groups, lactobacillus or bifidobacterium, although many other types of bacteria are also classified as probiotics. Scientific evidence shows these probiotics

• boost the immune system by enhancing the production of antibodies;
• support the synthesis of vitamins and other nutrients;
• relieve the effects of, and treat, intestinal illness (diarrhea, constipation, IBS);
• prevent and treat vaginal yeast infections and urinary tract infections; and
• may reduce the risk of colon or bladder cancer.

Two ways to boost healthy GI flora are to take a probiotic supplement or add probiotic-containing foods to your diet. Probiotic supplements come in liquid and capsule forms and many are sold refrigerated. Check with your Dr. Bossio to be sure you select a product that meets your personal health needs. It is important to follow the storage instructions for your supplement--failure to do so could kill off the live, healthy bacteria it contains.

Probiotic-boosting foods include fermented foods and cultured dairy products. Be sure the food labels state "fermented" or, for dairy, "live and active bacterial cultures."
