Is buttermilk acidic or alkaline?

Buttermilk is slightly acidic, it has a pH of 4.4-4.8, however, it is not very acidic, so it should be safe for people with acid reflux.

The pH of the stomach is usually between 1.5 and 3.5 (very acidic), however, while eating this can increase up to 6. Buttermilk helps to keep the acidity in the ideal range, neither too acidic, nor too alkaline.

Is buttermilk high in fats?


According to Live Science, a cup of buttermilk contains about 2.2 grams of fat, while milk contains about 8 grams.

Actually, about 90% of buttermilk is water, the rest is lactose, protein, and fat.

This relatively low-fat content is great news for people suffering from acid reflux or GERD, as it means it is easier to digest buttermilk than milk.

Is buttermilk good for acidity?

Yes, a cup of buttermilk after large meals has many benefits for people suffering from acidity.

Every time you consume hard-to-digest fatty foods, red meat, fried foods, or spicy foods, you make your body vulnerable to acid reflux and heartburn.

Many people find that buttermilk – or other fermented milk products is a good remedy for their acid reflux symptoms. Buttermilk helps digestion in two ways:

Buttermilk and acidity

As mentioned above buttermilk is slightly acidic with a pH of around 4.5.

After a large meal, the acidity of the stomach might increase up to a pH of 6. When the pH in the stomach is too high, digestion slows down and this might trigger all kinds of symptoms.

Buttermilk helps to reduce this increased stomach pH and keep it in the ideal range for digestion.

Buttermilk and lactic acid

Buttermilk is a dairy product, and it occurs naturally as a probiotic, meaning that it works well in helping digestion.

A glass of cold buttermilk is a perfect antidote for acidity. This is because buttermilk contains lactic acid. This is how it helps to relived reflux symptoms:

  • Probiotics: Probiotics contain bacteria that ensure that there is no bloating or gas build-up. When these two are dealt with, it is unlikely to suffer from acid reflux.
  • Coats the stomach: Lactic acid is responsible for soothing the stomach because it coats its lining, thus reducing the symptoms of acid reflux and any irritation resulting from it.

The daily consumption of buttermilk or similar supplements – like yogurt, or probiotic capsules – can be perfect for preventing acid reflux.

Buttermilk for heartburn

Buttermilk is a popular and effective heartburn remedy.

Heartburn happens when stomach acids are allowed to flow back (reflux) into the esophagus. The digestive juices irritate the lining of the esophagus, causing a burning sensation around the middle of the chest, called heartburn.

Eliminate acid reflux offer

Heartburn is a common symptom of acid reflux and GERD (gastroesophageal reflux disease, the chronic form of acid reflux, more than two episodes per week).

The probiotics in buttermilk increase gut motility, which reduces pressure in the stomach, and undigested food spends less time in the stomach. Both of these reduce the risk of heartburn.

Does buttermilk cause gas?

Buttermilk should not cause gas in healthy people when consumed in moderate amounts. On the contrary, it should relieve gas and bloating problems after eating.

This is because buttermilk is full of good bacteria (probiotics) that help digestion and prevent gas forming.

However, some people might experience gas after consuming buttermilk. The possible reasons are:

  • If you’ve just started drinking buttermilk and your body is not used to it, the body might need a short adjustment period to get used to the new food and during this period you might experience some gas.
  • While moderate amounts prevent gas and bloating, too much buttermilk can cause gas and diarrhea. It can also increase the sodium level of the body, which might trigger other symptoms.
  • Even though it is easier to digest buttermilk than milk, those who are lactose intolerant might still experience unpleasant gastrointestinal symptoms, like gas.

Substitutes if you have lactose intolerance

Buttermilk might or might not trigger symptoms for people with lactose intolerance. However, if you are allergic to milk, you should avoid buttermilk, too.

Lactose intolerance is a situation where your body is incapable of breaking the lactose in milk.

Buttermilk contains bacteria that help in the digestion of lactose, however, it also contains lactose, so depending on how sensitive you are to lactose, you might experience symptoms.

Possible alternatives are lactose-free buttermilk, or plant-based milks, like:

  • soy milk
  • almond milk
  • rice milk
  • coconut milk

Make sure to check the contents of plant-based milks, as it might be very different from cow milk or buttermilk.

Final thoughts

To sum up, the probiotics in buttermilk facilitate digestion and neutralize acidity, therefore buttermilk is considered to be an effective and natural heartburn remedy.

Buttermilk can be used to relieve after-eating symptoms like heartburn or chest pain, but it is also effective in preventing the symptoms to develop.

In case you suffer from acid reflux, you might try to drink a glass of buttermilk after meals to see if it helps with your symptoms.

If you have lactose intolerance then buttermilk might need to be substituted with a plant-based alternative or lactose-free dairy products.
