Risks and contraindications of kombucha tea

Before deciding to drink this drink, you must be aware that in certain cases it is not advisable to take it, since it can cause adverse reactions or other health problems and, therefore, it is convenient to know what the risks and contraindications of kombucha tea are :

  • Pregnant and lactating women: because they are microorganisms of this type, it is recommended that pregnant and lactating women avoid their consumption, as it can affect both the fetus and the newborn baby. In addition, derived from the fermentation process, alcohol is produced, which at the end of the drink is reduced to less than 1% by the action of bacteria, but which is still contraindicated for these women.
  • Children under 12 years of age: their digestive system is not yet ready for this type of drink.
  • Diabetics: the base of this tea contains a lot of sugar and, although most of it is fermented by the microorganisms that are introduced, in the resulting drink sugar levels can persist that alter blood glucose and, therefore, affect those who suffer type 1 and type 2 diabetes .
  • Patients with a weak immune system: as it is a colony of microorganisms, it is very risky to take it if our immune system is too weakened. Although it strengthens the defenses, if we have them too low, it is most likely that health will deteriorate.

Likewise, it is contraindicated in cases of kidney, liver, heart disease and clotting problems. In addition, if we prepare this drink at home, there are more health risks, since during the process there can be cross contamination that results in the tea containing other types of bacteria and fungi . For this reason, it is more advisable to buy the drink already prepared, since the supervision of the quality of the tea at home is less precise than in a manufacturing process that must pass quality tests by law.

It should also be taken into account that it is a drink with an acidic pH (between 2 and 3) and that therefore it can cause metabolic acidosis if consumed in excess.
