Understanding Yogurt and FODMAPs
For individuals following a low FODMAP diet, understanding why traditional cow's milk yogurt can be problematic is the first step. The primary FODMAP in dairy products is lactose, a disaccharide sugar. People with lactose intolerance have insufficient lactase enzymes to properly break down this sugar, which leads to fermentation in the gut and can cause symptoms like bloating, gas, and abdominal pain. The good news is that yogurt undergoes a fermentation process that naturally reduces its lactose content compared to milk, and many lactose-free and dairy-free options are now widely available.
Low FODMAP Yogurt Options
Several types of yogurt are suitable for a low FODMAP diet, provided you choose plain, unflavored varieties and check the ingredients list carefully for hidden FODMAPs.
Lactose-Free Dairy Yogurt
This is often the safest and most straightforward option for those who want to consume dairy. These yogurts have the lactase enzyme added during production to break down the lactose, making it easily digestible. Monash University has tested plain, lactose-free yogurts and found generous low FODMAP serving sizes.
- Plain, Unsweetened Lactose-Free: These are the most versatile and safest options, as they do not contain added sugars or flavorings that could be high in FODMAPs.
- Lactose-Free Greek Yogurt: The straining process for Greek yogurt removes more lactose than regular yogurt, and when made with lactose-free milk, it's a gut-friendly, higher-protein choice.
Dairy-Free Plant-Based Yogurts
For those with a dairy allergy or a preference for plant-based foods, several dairy-free yogurts can be low FODMAP.
- Coconut Yogurt: Plain coconut yogurt is a popular and safe low FODMAP choice in a standard serving size (around 1/2 cup or 125g). Be sure to check the label, as some brands may add high FODMAP ingredients.
- Almond Yogurt: While almonds are low FODMAP in small quantities, almond milk yogurts have been tested by Monash University to be low FODMAP in reasonable servings (around 1/2 cup). Look for products made with soy protein isolate, not whole soybeans, and avoid high FODMAP additives.
- Soy Yogurt: Only soy yogurt made from soy protein isolate is considered low FODMAP. Avoid yogurts made from whole soybeans, as they are high in FODMAPs like GOS and fructans.
Greek Yogurt
Regular Greek yogurt has lower lactose than regular yogurt because of the straining process. While some people with IBS may tolerate small amounts (as little as 23g or ~3 tbsp), it is considered moderate to high FODMAP in larger servings by Monash University. Choosing a lactose-free Greek yogurt is the safest option during the elimination phase of the diet.
What to Avoid When Buying Yogurt
Reading the ingredients list is crucial, as many seemingly innocent products contain hidden high-FODMAP ingredients. Be vigilant for:
- High FODMAP Sweeteners: High-fructose corn syrup, honey (in large amounts), agave syrup, and sugar alcohols like sorbitol, xylitol, and mannitol.
- High FODMAP Fruits: Avoid yogurts with high FODMAP fruits like mango, peach, cherry, or larger quantities of apples.
- Added Fibers: Inulin or chicory root fiber are often added for texture or health claims but are high in FODMAPs.
- Whey Protein Concentrate: This can be added to some yogurts and may be a source of concentrated lactose.
Finding the Right Low FODMAP Yogurt for You
Comparison Table: Low FODMAP Yogurt Choices
| Type of Yogurt | Lactose Content | FODMAP Consideration | Safe Serving Size (approx.) |
|---|---|---|---|
| Lactose-Free Dairy | Negligible | Made safe by adding lactase enzyme; versatile option. | Generous (often up to 500g, check label) |
| Greek (Regular) | Lowered by straining | Moderate FODMAP in standard servings; very small portions may be tolerated. | 23g (~3 tbsp) |
| Coconut Yogurt (Plain) | None | Naturally low FODMAP; check for high FODMAP additives. | 125g (1/2 cup) |
| Almond Yogurt (Plain) | None | Untested by Monash, but small portions are likely fine; check ingredients. | 1/2 cup |
| Soy Yogurt | None | Only safe if made from soy protein isolate, not whole soybeans. | Varies, check for isolate |
The Importance of Certified Products
To make shopping easier, look for products certified by organizations like Monash University or FODMAP Friendly, which will have a specific logo on their packaging. This guarantees the product meets low FODMAP standards at the recommended serving size. You can also utilize the Monash University FODMAP Diet App for the most comprehensive and up-to-date food database.
Conclusion
While traditional cow's milk yogurt is typically high in lactose and should be avoided during the elimination phase of a FODMAP diet, many excellent alternatives exist. Lactose-free dairy yogurts, plain coconut yogurt, and soy yogurt made from protein isolate are safe, compliant options when selected carefully. The key is to always read the ingredient list to avoid hidden FODMAPs, be mindful of serving sizes, and listen to your body to determine your individual tolerance. This empowers you to enjoy yogurt and its benefits without triggering digestive discomfort.

Frequently Asked Questions
Q: Is all lactose-free yogurt low FODMAP? A: Not necessarily. While lactose is removed, the product can still contain other high FODMAP ingredients like inulin, honey, or fruit purees. Always check the ingredients list for added FODMAPs.
Q: What is a safe serving size for Greek yogurt on the FODMAP diet? A: Monash University lists a small serving of 23g (or about 3 tablespoons) of regular Greek yogurt as low FODMAP. For larger servings, opt for a lactose-free Greek yogurt variety.
Q: Can I have flavored yogurt on a low FODMAP diet? A: It's best to stick to plain, unflavored yogurts during the elimination phase. Many flavored yogurts contain high FODMAP sweeteners (like high-fructose corn syrup) or fruit purées (like mango or cherry).
Q: Is soy yogurt safe for a low FODMAP diet? A: Yes, but only if it's made from soy protein isolate. Soy yogurts made from whole soybeans are high in FODMAPs like GOS and fructans and should be avoided.
Q: How do I know if a plant-based yogurt is low FODMAP? A: Check the base ingredient (e.g., coconut is usually fine, almond is likely fine in small servings, soy must be protein isolate) and read the label for high FODMAP sweeteners and added ingredients like inulin. Certified low FODMAP products are the safest bet.
Q: Are probiotics in yogurt helpful for IBS? A: Some studies suggest that probiotics in yogurt may help with IBS symptoms. Choosing a yogurt with live cultures that is also low FODMAP can be a good way to get these potential benefits.
Q: Is frozen yogurt low FODMAP? A: Frozen yogurt is typically high in FODMAPs due to added sugars and ingredients. It is not a recommended choice. Look for frozen lactose-free yogurt or sorbets made from low FODMAP fruits instead.
