Fermented foods for digestion -

Justin and Erica Sonnenburg and Christopher Gardner are co-senior authors. The lead authors are Hannah Wastyk , a PhD student in bioengineering, and former postdoctoral scholar Gabriela Fragiadakis, PhD, who is now an assistant professor of medicine at UC-San Francisco.

A wide body of evidence has demonstrated that diet shapes the gut microbiome, which can affect the immune system and overall health. According to Gardner, low microbiome diversity has been linked to obesity and diabetes.

The researchers focused on fiber and fermented foods due to previous reports of their potential health benefits. While high-fiber diets have been associated with lower rates of mortality, the consumption of fermented foods can help with weight maintenance and may decrease the risk of diabetes, cancer and cardiovascular disease.

The researchers analyzed blood and stool samples collected during a three-week pre-trial period, the 10 weeks of the diet, and a four-week period after the diet when the participants ate as they chose.

The findings paint a nuanced picture of the influence of diet on gut microbes and immune status. On one hand, those who increased their consumption of fermented foods showed similar effects on their microbiome diversity and inflammatory markers, consistent with prior research showing that short-term changes in diet can rapidly alter the gut microbiome.

The results also showed that greater fiber intake led to more carbohydrates in stool samples, pointing to incomplete fiber degradation by gut microbes. These findings are consistent with other research suggesting that the microbiome of people living in the industrialized world is depleted of fiber-degrading microbes.

In addition to exploring these possibilities, the researchers plan to conduct studies in mice to investigate the molecular mechanisms by which diets alter the microbiome and reduce inflammatory proteins. They also aim to test whether high-fiber and fermented foods synergize to influence the microbiome and immune system of humans.

Another goal is to examine whether the consumption of fermented food decreases inflammation or improves other health markers in patients with immunological and metabolic diseases, and in pregnant women and older individuals.

Fermented-food diet increases microbiome diversity, decreases inflammatory proteins, study finds. There are no official recommendations for how often you should eat fermented foods, but research suggests that regularly including them into your diet may help bolster gut health and fight inflammation.

One small study reported that people who consumed six servings of fermented foods daily for 10 weeks experienced significant reductions in inflammatory markers and an increase in gut microbiome diversity compared to study participants who doubled their dietary fiber intake and did not eat fermented foods during the trial.

Whether you need to consume six servings of fermented foods every day in order to reap their benefits remains to be seen. For now, try incorporating at least one fermented food into your diet daily by enjoying kefir at breakfast, sipping on some kombucha with lunch, or adding a spoonful of sauerkraut to a grain bowl at dinner.

To properly ferment foods at home, you will need sterilized glass jars, salt, a cloth napkin or cheesecloth, and whatever ingredients you intend to ferment. Here are general steps for making fermented vegetables at home:. Common side effects of eating fermented foods can include digestive symptoms, such as abdominal bloating and gas, in sensitive individuals.

Preparing fermented foods at home without following proper food safety standards such as not washing your hands properly or not using sterilized jars can increase the risk of harmful microbes growing in your food.

Improper storage of fermented foods can also heighten the risk of contracting a foodborne illness after consumption. Eating fermented foods may also pose risks for people diagnosed with a histamine intolerance, those who suffer from migraines , and individuals taking monoamine oxidase inhibitors MAOI medications.

If this is you, talk to your healthcare provider about whether regularly eating fermented foods is safe for you.

Fermented ingredients are those that are produced with microorganisms such as bacteria or yeast and undergo chemical changes as a result. Some ingredients are fermented but do not contain any active bacteria. Here are a few examples:. Other fermented foods contain active bacteria, but have not yet been confirmed to act as probiotics.

According to the International Scientific Association of Probiotics and Prebiotics, in order for a fermented food to be accurately labeled as a probiotic, it must:. If fermented foods are new to you, start slowly by incorporating one to two servings of fermented foods daily to assess your tolerance.
