Some of the types of milk you can use include the following:

  • goat
  • sheep
  • cow
  • soy
  • rice
  • coconut

Kefir is made using starter grains that are a combination of bacteria and yeast. As it interreacts with milk, it creates a fermented drink that boosts your nutrients and promotes health. Since it is fermented, it might taste slightly carbonated but still maintain a creamy consistency.

Much of the kefir benefits are due to its high probiotic content. Probiotics are living organisms that promote gut health and other conditions. While kefir is healthy, there are some risk factors to be aware of for some people.

If you have a milk allergy, you shouldn’t consume kefir. It is safe for those with lactose intolerance, but a milk allergy could pose a problem.

Another thing to consider is that many pre-packaged kefir options contain high amounts of added sugar. The added sugar negates many of the health benefits and could lead to further health issues for you. Try to avoid any kefir that contains high sugar levels so that you can ensure you consume the healthiest option.
