Milk Products – Cultured / Fermented

Acceptable Keto IngredientWhat are Cultured Milk Products?

Cultured milk products are created when milk ferments with specific kinds of bacteria called Lactobacilli or Bifidobacteria. Fermentation means the milk is partially digested by the bacteria. This makes the milk product easier to digest, especially for people who have milk allergies or are lactose intolerant.

Also, fermentation increases how long the milk product will last on the shelf. Cultured cream or sour cream is cream that has gone through a fermentation process. This process consists of the bacteria converting milk sugars into lactic acid. Aroma compounds, mostly diacetyl, are produced – diacetyl is responsible for the more “buttery”, fuller flavor of cultured cream.

Keto Status?



Cultured Milk Products are considerably low carb as ingredients, but are even considered keto-friendly if drinking plain. They contain 10-12 carbs per 1 cup serving, so go easy, but they will fit a ketogenic diet. They are also linked to many health benefits including:

  • Antibacterial properties
  • Improve bone health and reduce the risk of osteoporosis
  • Improve digestion and minimize symptoms of IBS
  • Treat yeast infections, such as an overgrowth of candida
  • Boost immunity
  • Improve allergy and asthma symptoms
  • May fight cancer-causing free radicals

Possible Side Effects From Ingesting Cultured Milk Products?

I Heart Keto Mart Rating Guide

I Heart Keto Mart rates all ingredients through a “keto diet” & “low carb diet” lens. As an example, peas would be rated as “Acceptable” on a non-keto healthy diet; however, due to their carbohydrate level, we rate them “Objectionable”. We also rate all sweeteners that typically cause a rise in blood sugar and insulin levels as “Objectionable”. If you prefer a natural sweetener, like honey, over a sugar alcohol like erythritol, you may not agree with our “Objectionable” rating. I Heart Keto Mart rates all ingredients based first and foremost for those that have a sugar/carbohydrate addiction. Ingredients are rated for those who must moderate if not completely abstain from any sugars. If you have questions about this, please refer to this article: Why Some Whole Foods Are Not Keto Friendly


I Heart Keto Mart is not a health care provider. We are an online keto educational site that shares keto approved products and low carb products and defines and rates their ingredients. I Heart Keto Mart’s hope is that our viewers will educate themselves on “all things ingredients” so they can easily identify keto approved ingredients and eliminate or greatly restrict unacceptable keto ingredients. I Heart Keto Mart is the best online keto store and online low carb store with 1000s of products and an informative blog that shares keto articles and keto recipes, interviews keto coaches and keto product manufacturers and so much more.  We are keto affiliates and each of the keto approved products we rate is linked to the vendor’s site where the product may be purchased. I Heart Keto Mart may earn a small commission from these sales. Amazon is one of these affiliates.
