When Should You Not Eat Sauerkraut?

pregnant, woman, belly

Pregnant women or any individual with compromised immunity should avoid eating unpasteurized sauerkraut. This is because it is rich in bacteria and when your immunity is compromised it increases your risk of developing a bacterial infection.

Patients consuming monoamine oxidase inhibitors (MOIs), best known as anti-depressant should avoid eating sauerkraut. If you are hypertensive, you should also be careful with consuming sauerkraut because of its high sodium content. Speak to your doctor before incorporating sauerkraut into your diet.

Individuals suffering from small intestinal bacterial overgrowth (SIBO) because these patients already have a lot of bacteria in their small intestine instead of their large intestine, so eating high-fiber and probiotic-rich foods will increase the number of the microbiome in your small intestine, leading to bloating.

Should Diabetics Eat Sauerkraut?

Diabetics can eat sauerkraut but be careful about the amounts you consume in one sitting. A cup of sauerkraut contains 923 mg of sodium. You would normally consume a quarter cup as a side which will provide 360 mg of sodium. The American Heart Association recommends consuming 1,500 mg of sodium per day for diabetics, so this amount gives you more than one-fifth of your recommended intake.

Sauerkraut will not affect your sugars because it is low carb and is a low glycemic index food. The only concern to look at is its sodium content. The other thing to look out for is the acidity of this food. Most diabetics suffer from acid reflux so it may not be too smart to pack on large amounts of acidic sauerkraut. Kimchi and kefir are less acidic fermented foods you can enjoy if you suffer from gastroesophageal reflux disease (GERD).

My suggestion spread out your sauerkraut throughout the day instead of eating the whole quarter cup in one sitting. However, in small amounts, you don’t have to worry about it spiking your sugars. It is a low-carb food after all so it will keep you in ketosis!

Bottom Line

Sauerkraut is a great addition to your keto foods considering what it can do to your gut and how many carbs in sauerkraut. Take advantage of not only the flavor but the benefits it can have to your overall health. You can have sauerkraut without worrying about its effects on your blood sugar since it is a low glycemic index food.
