5 Reasons Sauerkraut Could Be Giving You Diarrhea

Excessive Probiotic Intake - The consumption of raw sauerkraut introduces billions of probiotics into the digestive system. These trigger a cascading change in gut bio, which affects the absorption of water in the large intestine leading to diarrhea.

Excessive Dietary Fiber Intake - Consumption of too much dietary fiber can trigger diarrhea. Dietary fiber is water-soluble and draws in fluids, consuming too much of it leads to watery stool and dehydration.

Allergic Reaction - Sauerkraut has an above-normal concentration of histamine - the compound that triggers an immune response to allergens. When the sauerkraut is consumed, the body absorbs the histamines, which can then trigger an inflammatory response in the intestines leading to diarrhea.

Contamination - The presence of harmful contaminants in fermented sauerkraut can trigger an adverse reaction in the digestive system leading to diarrhea. When your digestive system senses the presence of harmful contaminants in the digestive system, it will try to flush them out quickly via diarrhea.

Consuming Too Much Too Fast - Consuming too much sauerkraut can trigger diarrhea, especially if it's your first time trying out sauerkraut.

1.  Eat Smaller Servings

Starting off with small serving amounts will give your digestive system time to adapt to a sauerkraut diet. The daily intake can then be scaled up as needed over a couple of days to avoid any adverse effects on your digestive system.

Kombucha - Kombucha is a fermented drink that's prepared by aerobically fermenting sweetened tea in the presence of a SCOBY. The SCOBY introduces billions of live bacteria and yeast cells in the brew, which feed on the sugar and caffeine in the tea. The resulting brew is not only rich in probiotics but also free of Lacto bacteria.

Water Kefir - Water kefir relies on kefir grains to introduce a culture of lactic and acetic acid bacteria that break down the sugar in the water giving the drink its characteristic fizziness.

Strong Belgian Beers - Strong beers, particularly Belgian ones, undergo double fermentation, which increases the flavor and probiotic content. However, it's important to remember that alcohol can be harmful to the gut bio if consumed in excessive amounts.
