Is Yogurt Low FODMAP? A Complete Guide to Yogurt and IBS
Whether yogurt is low FODMAP depends on the type. Lactose-free yogurt is safe, while regular yogurt is high FODMAP. Learn about Greek yogurt, coconut yogurt, and kefir.
Whether yogurt is low FODMAP depends entirely on the type you choose. Lactose-free yogurt is low FODMAP and safe for people with IBS. Regular yogurt — including most Greek yogurt — is high FODMAP due to its lactose content. Coconut yogurt and other plant-based yogurts are generally safe, but you need to check for hidden high-FODMAP ingredients. The key FODMAP in yogurt is lactose, a disaccharide that many people with IBS absorb poorly.
Yogurt is a valuable food nutritionally, providing protein, calcium, and beneficial probiotics. Finding a low-FODMAP version that works for you means you can enjoy these benefits without triggering symptoms.
Why Is Regular Yogurt High FODMAP?
Regular yogurt contains lactose, the naturally occurring sugar in milk. Lactose is a disaccharide made up of glucose and galactose bonded together. To digest lactose, your small intestine produces an enzyme called lactase that breaks this bond. Many people — and a disproportionate number of people with IBS — produce insufficient lactase, a condition called lactose malabsorption.
When undigested lactose reaches the large intestine, gut bacteria ferment it rapidly, producing gas, bloating, cramping, and diarrhea. This is the same mechanism behind the symptoms caused by milk and other high-lactose dairy products.
While yogurt fermentation does reduce some lactose (the bacterial cultures consume a portion during the culturing process), the reduction is typically only 20 to 30 percent — not enough to bring standard yogurt below the threshold for most sensitive individuals.
FODMAP Breakdown: Yogurt Types
| Yogurt Type | Serving Size | FODMAP Level | Primary FODMAP | Notes |
|---|---|---|---|---|
| Regular plain yogurt | 3/4 cup (170g) | High | Lactose | Not safe during elimination |
| Regular flavored yogurt | 3/4 cup (170g) | High | Lactose + possible fructose | Added sugars compound the issue |
| Greek yogurt (regular) | 3/4 cup (170g) | Moderate–High | Lactose | Lower lactose than regular, still significant |
| Lactose-free plain yogurt | 3/4 cup (170g) | Low | None | Safe choice |
| Lactose-free Greek yogurt | 3/4 cup (170g) | Low | None | Best option for protein |
| Coconut yogurt (plain) | 3/4 cup (170g) | Low | None | Check for added inulin |
| Almond milk yogurt | 3/4 cup (170g) | Low | None | Lower in protein |
| Soy yogurt (from soy protein) | 3/4 cup (170g) | Low | None | Check it’s not from whole soybeans |
| Kefir (regular) | 1 cup (250ml) | Moderate–High | Lactose | Fermentation reduces some lactose |
| Kefir (lactose-free) | 1 cup (250ml) | Low | None | Safe and probiotic-rich |
What About Greek Yogurt?
Greek yogurt gets special attention because it is strained, which removes much of the liquid whey — and with it, some lactose. A standard Greek yogurt contains roughly 4 to 6 grams of lactose per serving compared to 8 to 12 grams in regular yogurt. This is meaningfully less, and some people with mild lactose sensitivity may tolerate small amounts of Greek yogurt.
However, for the purposes of the elimination phase, Greek yogurt is still considered moderate to high FODMAP unless it is specifically labeled lactose-free. During elimination, it is best to use lactose-free Greek yogurt, which gives you the same thick, protein-rich texture with no FODMAP concerns.
Coconut Yogurt and Plant-Based Alternatives
Plant-based yogurts made from coconut, almond, oat, or soy are naturally lactose-free, which eliminates the primary FODMAP concern. However, not all plant-based yogurts are automatically low FODMAP. Watch out for these common additives:
- Inulin or chicory root fiber: Added for texture and marketed as a prebiotic, inulin is a fructan and is high FODMAP
- Honey or agave: High FODMAP sweeteners sometimes used in flavored varieties
- Apple juice concentrate: Contains excess fructose
- Large amounts of coconut cream: Coconut in very large amounts can become moderate FODMAP, though typical yogurt servings are fine
- Soy from whole soybeans: Soy yogurt made from whole soybeans contains GOS; those made from soy protein isolate are low FODMAP
Plain, unsweetened coconut yogurt is generally your safest plant-based option. It pairs well with low-FODMAP fruits like blueberries, strawberries, and unripe bananas.
Kefir: Is It a Better Option?
Kefir is a fermented milk drink made with kefir grains, which contain a more diverse culture of bacteria and yeasts than yogurt. The extended fermentation process reduces lactose further than standard yogurt production, and some studies suggest that kefir may be better tolerated by people with lactose malabsorption.
However, regular kefir still contains enough residual lactose to be problematic for many people with IBS. Lactose-free kefir is available and is a safe low-FODMAP option that also delivers a wider range of probiotic strains than most yogurts.
Probiotics, Yogurt, and IBS
There is growing research interest in the role of probiotics for IBS management. Yogurt and kefir naturally contain live bacterial cultures, and some evidence suggests that regular consumption of specific strains may help with:
- Reducing bloating and gas production
- Improving stool consistency
- Modulating the gut-brain axis
- Supporting the gut microbiome diversity that is often reduced in IBS patients
The challenge is that the probiotic benefit must not come at the cost of FODMAP-triggered symptoms. If regular yogurt causes you bloating, the probiotic bacteria in it are not going to offset the immediate discomfort from undigested lactose. Choose lactose-free yogurt with live active cultures to get the best of both worlds.
How to Choose the Right Yogurt for IBS
Follow these guidelines when shopping:
- Check the label for “lactose-free”: This is the single most important thing. If it says lactose-free, the manufacturer has added lactase enzyme to pre-digest the lactose.
- Choose plain over flavored: Flavored yogurts often contain high-FODMAP sweeteners, fruit purees, or additives like inulin.
- Look for live active cultures: These are listed on the label and indicate the yogurt contains beneficial probiotics.
- Check protein content: Lactose-free Greek yogurt typically provides 12 to 18 grams of protein per serving, making it one of the most nutrient-dense low-FODMAP foods available.
- Scan the ingredients: If you are unsure whether a yogurt is safe, use FODMAPSnap to quickly check the ingredients against known FODMAP data.
Yogurt in Cooking and Baking
Yogurt is a common ingredient in marinades, dressings, baked goods, and sauces. In all cases, simply substitute lactose-free yogurt for regular yogurt in a 1:1 ratio. The taste, texture, and cooking properties are virtually identical. Lactose-free yogurt works perfectly in:
- Smoothies (blend with low-FODMAP fruits and a handful of spinach)
- Marinades for chicken or lamb (yogurt tenderizes the meat)
- Salad dressings (mix with herbs, lemon, and olive oil)
- Baking (replace regular yogurt in muffins, cakes, and pancakes)
Reintroduction: Testing Your Lactose Tolerance
During the FODMAP reintroduction phase, you will test lactose by consuming increasing amounts of regular yogurt or milk over three days. Many people discover they have a partial tolerance — perhaps a few tablespoons of regular yogurt are fine, but a full serving causes symptoms. This threshold information helps you decide whether you can occasionally enjoy regular yogurt or should stick with lactose-free versions long-term.

Frequently Asked Questions
Is Greek yogurt low FODMAP?
Regular Greek yogurt is not low FODMAP, though it contains less lactose than standard yogurt due to the straining process that removes whey. A small serving (about 3/4 cup or 170g) of Greek yogurt still contains enough lactose to trigger symptoms in people with IBS who are sensitive to lactose. However, lactose-free Greek yogurt is available from several brands and is a safe low-FODMAP choice.
Is coconut yogurt low FODMAP?
Most coconut yogurt is low FODMAP because it is naturally lactose-free. However, you should check the ingredients for added high-FODMAP sweeteners like honey, agave, or inulin (chicory root fiber), which some brands include. Plain, unsweetened coconut yogurt is generally the safest option. Some coconut yogurts use coconut cream, which is low FODMAP at standard yogurt serving sizes.
Does the fermentation process reduce lactose in yogurt?
Yes, fermentation does reduce lactose content in yogurt compared to plain milk. The bacterial cultures (Lactobacillus and Streptococcus species) consume some of the lactose as fuel during fermentation, converting it to lactic acid. However, the reduction is typically only 20 to 30 percent, which is not enough to make regular yogurt safe for most lactose-sensitive IBS patients. Longer fermentation times reduce lactose further, which is why some traditional yogurts may be better tolerated.
Can probiotics in yogurt help IBS?
Some research suggests that specific probiotic strains found in yogurt, particularly Lactobacillus and Bifidobacterium species, may help reduce IBS symptoms over time. However, the probiotic benefit does not outweigh the FODMAP risk if the yogurt contains lactose that triggers your symptoms. Choose lactose-free yogurt with live active cultures to get the potential probiotic benefit without the FODMAP load.
