Yoghurt is often one of the foods people question when they experience acid reflux. Some people find that dairy products aggravate their symptoms, while others find yoghurt to be a convenient, well-tolerated snack that sits comfortably in their stomach.
But could yoghurt actually help with reflux?
Interestingly, emerging research suggests that certain probiotic-containing yoghurts may have a beneficial effect on gastro-oesophageal reflux symptoms. While the evidence is still developing, there are some promising findings worth exploring.
Let’s take a closer look at what the research says, whether all yoghurts offer the same benefits, which probiotic yoghurts are worth considering and how much yoghurt you should include in your diet.
First, what is acid reflux?
Gastro-oesophageal reflux occurs when stomach contents travel backwards into the oesophagus (the tube connecting your mouth to your stomach).
This can cause symptoms such as:
- Heartburn or a burning sensation in the chest.
- Regurgitation of stomach contents into the throat or mouth.
- An unpleasant sour or acidic taste.
- Symptoms that worsen after eating or when lying down.
Occasional reflux is relatively common. However, when reflux becomes frequent or troublesome, it may be diagnosed as gastro-oesophageal reflux disease (GORD).
Diet can influence symptoms, but there is no universal list of foods that everyone with reflux needs to avoid. Individual tolerance, meal size, fat content and eating habits can all play a role.
Does yoghurt make acid reflux worse?
Not necessarily!
Yoghurt is sometimes included on lists of foods to avoid when experiencing reflux, particularly because dairy products can contain varying amounts of fat.
Higher-fat meals may influence lower oesophageal sphincter function and gastric emptying in some individuals. This may contribute to reflux symptoms, particularly when meals are large.
However, this does not mean that all yoghurt causes reflux.
In fact, there is insufficient evidence to suggest that yoghurt needs to be routinely excluded from the diet of someone experiencing GORD.
It is therefore worth considering the type of yoghurt, its fat content and individual tolerance rather than automatically eliminating dairy.
Can probiotic yoghurt actually help acid reflux?
This is where things become particularly interesting!
Probiotics are live microorganisms that, when consumed in adequate amounts, provide a health benefit to the person consuming them.
Certain probiotic strains have been investigated for their potential effects on gastrointestinal function, including digestive symptoms associated with reflux.
A systematic review published in 2020, titled Gastroesophageal Reflux Disease and Probiotics: A Systematic Review, examined the available research investigating probiotics and reflux.
The researchers identified potential improvements in:
- Heartburn.
- Regurgitation.
- Reflux-related symptom scores.
- Gastrointestinal discomfort.
Some of the studies investigated probiotic-containing fermented dairy products, including yoghurt.
However, the studies varied considerably in their design, probiotic strains, doses and duration. The results should therefore be interpreted cautiously.
What did the 2022 systematic review and meta-analysis find?
A particularly relevant paper was published by Martin and colleagues in 2022 in Clinical Nutrition ESPEN.
The researchers investigated the effectiveness of dietary interventions, nutraceuticals and probiotics for managing gastro-oesophageal reflux symptoms.
Their review identified 6,608 records, with 21 studies ultimately included.
Interestingly, probiotic yoghurt was among the interventions associated with clinically and statistically significant improvements in reflux symptoms.
However, this finding was based on one intervention study rather than a pooled analysis of multiple probiotic yoghurt trials.
The authors concluded that the overall evidence for dietary management of reflux remains limited and that dietary strategies should be individualised.
This is an important distinction. While the findings are promising, probiotic yoghurt should not currently be considered an established treatment for GORD.
How might probiotics help with reflux?
Researchers are still investigating exactly how probiotics may influence reflux symptoms.
Some proposed mechanisms include:
1. Supporting gastrointestinal motility
Certain probiotic strains may influence gastrointestinal motility and gastric emptying. This is potentially relevant because delayed gastric emptying can contribute to post-meal fullness and discomfort in some people.
2. Influencing the gut microbiota
Probiotics may help influence the composition and activity of the gastrointestinal microbiota. Changes in the gut microbiota have been investigated in relation to several gastrointestinal conditions.
3. Improving overlapping digestive symptoms
Some probiotics have demonstrated benefits for symptoms such as bloating, abdominal discomfort and digestive irregularity.
These symptoms can occur alongside reflux, although improving bloating or digestive discomfort does not necessarily mean that the amount of acid reflux is reduced.
It is also important to remember that probiotic effects are strain-specific. Different probiotic species and strains can have different effects, so simply choosing a yoghurt that contains live cultures does not guarantee the same benefits.
Not all yoghurts are probiotic yoghurts! Here’s what to look for
This is an important point when choosing a yoghurt.
All traditional yoghurt contains live bacterial cultures used during fermentation. These commonly include:
- Streptococcus thermophilus.
- Lactobacillus delbrueckii subsp. bulgaricus.
However, these traditional starter cultures are not automatically classified as probiotics.
To be considered a probiotic, a microorganism needs to have demonstrated a health benefit when consumed in adequate amounts. This means that a yoghurt containing live cultures is not necessarily equivalent to one containing additional, researched probiotic strains.
When shopping, look for products that identify their probiotic cultures and, ideally, specify the strain and the number of colony-forming units (CFUs).
Which probiotic yoghurts are available in Australia?
There are several Australian supermarket options that specifically identify additional probiotic cultures.
1. Vaalia Probiotic Yoghurt
Vaalia is a particularly useful option to consider.
Its probiotic range contains a combination of:
- Lactobacillus rhamnosus GG (LGG).
- Bifidobacterium animalis subsp. lactis BB-12.
- Lactobacillus acidophilus LA-5.
Vaalia’s product information identifies these additional probiotic cultures and their quantities.
Its natural low-fat yoghurt is also a useful source of protein, providing approximately 9 g per 150 g serve, with relatively little fat.
This may be a practical choice for someone who finds higher-fat dairy products aggravate their reflux symptoms.
2. Activia Probiotic Yoghurt
Activia contains the specific probiotic strain Bifidobacterium animalis subsp. lactis CNCM I-2494, also marketed as Bifidus ActiRegularis.
Its natural yoghurt provides approximately 4.4 billion CFU per 125 g serve, according to product information.
Activia also offers flavoured varieties, including vanilla and strawberry, which can be convenient options.
The manufacturer recommends consuming 250 g daily for its digestive discomfort benefit as part of a healthy diet and lifestyle. This recommendation relates to general digestive comfort, not a clinically established reflux treatment dose.
3. Jalna Greek+ Probiotics
Jalna Greek+ Probiotics is another option, containing a combination of additional probiotic cultures, including:
- Lactobacillus acidophilus.
- Bifidobacterium.
- Lactobacillus casei.
- Lactobacillus rhamnosus.
- Lactobacillus paracasei.
The manufacturer lists more than one billion probiotic organisms per serve.
One consideration is that this product is made with whole milk and cream and has a considerably higher fat content than reduced-fat yoghurt.
For someone who experiences reflux after higher-fat foods, a lower-fat option may be worth trialling first.
A note about choosing probiotic yoghurt: Product formulations can change, so check the ingredients and probiotic information on the packaging. Not every Greek, natural or high-protein yoghurt is a probiotic yoghurt.
How much probiotic yoghurt should you eat?
An important question is whether there is an established therapeutic dose of yoghurt for reflux.
At present, there is no universally established probiotic yoghurt dose for treating GORD.
However, some of the research provides useful information.
Research investigating Lactobacillus gasseri OLL2716 (LG21) has examined yoghurt containing approximately one billion CFU of this specific probiotic strain, consumed daily over 12 weeks.
These findings are interesting, but it is important to recognise that the specific LG21 strain used in these studies is not the same as the probiotic strains found in the Australian supermarket products listed above.
We cannot assume that 118 g of any probiotic yoghurt will produce the same results.
My practical recommendation
For someone wanting to include probiotic yoghurt as part of their diet, I would suggest:
- Start with 100–150 g in your diet, although there is currently no established therapeutic dose for reflux. Including yoghurt with other tolerated foods can also improve acceptance.
- Choose a yoghurt that identifies its probiotic strains and CFU content.
- Consider a lower-fat option if higher-fat foods appear to trigger symptoms.
- Include it regularly rather than expecting an immediate effect.
- Monitor symptoms and adjust the portion or product according to individual tolerance.
A 100–150 g daily serve is a practical food-based starting point, not a proven therapeutic dose for reflux.
If someone wishes to trial a probiotic yoghurt specifically for digestive symptoms, an 8–12 week period may be reasonable for monitoring tolerance and any perceived changes. However, this duration has not been established as an optimal reflux treatment protocol.
Yoghurt Provides Your Body with Much More Than Probiotics
While we are talking about yoghurt, it is worth remembering that it can also make a valuable contribution to your daily nutritional requirements.
According to the Australian Guide to Healthy Eating (AGHE), 200 g of yoghurt is equivalent to one serve from the milk, yoghurt, cheese and alternatives food group.
For adults aged 19–50 years, the general recommendation is 2.5 serves from this food group each day.
Yoghurt provides several important nutrients, including:
- Calcium: Supports bone and dental health.
- Protein: Supports muscle maintenance and repair.
- Vitamin B12: Important for normal nervous system function and red blood cell production.
- Riboflavin (vitamin B2): Supports normal energy metabolism.
- Phosphorus: Helps maintain healthy bones and teeth.
So, a 200 g tub of yoghurt can be a convenient way to contribute towards your daily dairy requirements while also providing live probiotic cultures, depending on the product selected.
Remember, the 200 g dairy serve recommendation is a food-group serving guideline, not a proven therapeutic dose for reflux.
You also don’t need to consume 200 g specifically to obtain probiotic benefits. A smaller portion may be more comfortable for someone who experiences symptoms with larger meals or snacks.
Other things to consider when choosing yoghurt for reflux
Probiotic content is not the only consideration.
Fat content
If high-fat meals aggravate symptoms, consider starting with reduced-fat or low-fat yoghurt.
Lactose tolerance
Some people experience bloating, gas and abdominal discomfort after consuming lactose. While yoghurt is often better tolerated than milk because fermentation reduces some of its lactose content, tolerance varies.
Lactose-free yoghurt may be worth considering if lactose causes additional gastrointestinal symptoms.
Portion size
Larger meals and snacks can increase stomach distension and contribute to reflux in susceptible individuals. A smaller yoghurt serve may be more comfortable than a large bowl.
Timing
Avoid lying down immediately after eating. People experiencing troublesome reflux are generally advised to leave approximately 2–3 hours between their last meal and lying down.
Individual tolerance
There is no requirement to eat yoghurt if it consistently aggravates symptoms. Other sources of probiotics and beneficial dietary microorganisms may be considered, depending on individual tolerance.
Take Home Message
Yoghurt does not need to be automatically excluded from the diet when someone experiences acid reflux.
In fact, emerging research suggests that certain probiotic-containing yoghurts may have a beneficial effect on reflux-related symptoms.
The 2022 systematic review and meta-analysis by Martin and colleagues identified probiotic yoghurt as a promising dietary intervention, although the finding was based on a single study.
If you are interested in trying probiotic yoghurt, look for products that contain specifically identified probiotic strains, such as Vaalia, Activia or Jalna Greek+ Probiotics, rather than assuming all yoghurts offer the same benefits.
A daily serve of approximately 100–150 g is a reasonable starting point for inclusion in the diet, although there is currently no established therapeutic dose for reflux.
For general nutrition, remember that 200 g of yoghurt counts as one serve from the Australian Guide to Healthy Eating’s milk, yoghurt, cheese and alternatives food group.
Most importantly, dietary management should be individualised. There is no need to unnecessarily eliminate nutritious foods that are well tolerated.
