Yoghurt and Gut Health
Yoghurt is a cultured dairy product known for its probiotic potential and creamy texture. Its impact on gut health depends on factors like lactose content, fermentation, and individual sensitivities. Yoghurt can be beneficial for many, but may trigger symptoms in those with lactose intolerance, histamine intolerance, or milk allergy.
- FODMAP content depends on lactose level and portion size
- High in histamine due to fermentation; may trigger symptoms
- Contains live cultures that can support gut microbiota
- No fiber content in plain yoghurt
- Milk allergy risk; not suitable for people with dairy allergy
- Lactose content varies by type and brand
Yoghurt and FODMAPs
Yoghurt contains lactose, a FODMAP that can cause digestive symptoms in sensitive individuals. However, fermentation reduces lactose content, making small portions of regular yoghurt (up to 125 grams) often tolerable for people with lactose intolerance or IBS. Larger amounts or certain brands may still trigger symptoms, so portion control is important.

Histamine and Biogenic Amines in Yoghurt
Yoghurt is high in histamine due to the fermentation process. It may also contain other biogenic amines like tyramine. People with histamine intolerance or sensitivity should be cautious, as even small servings can provoke symptoms such as headaches, flushing, or digestive upset. Some individuals may also react to yoghurt as a histamine liberator.

Lactose Content and Tolerance
Lactose is present in yoghurt, but fermentation by live cultures reduces its amount. Many people with mild lactose intolerance can tolerate small servings of yoghurt, especially if it contains active cultures. Lactose-free yoghurts are also available for those who are highly sensitive.
Probiotics and Gut Microbiota
Yoghurt often contains live bacterial cultures such as Lactobacillus and Bifidobacterium. These probiotics can support a healthy gut microbiota, aid digestion, and may help reduce symptoms like bloating or irregularity in some individuals. The probiotic benefit depends on the type of yoghurt and whether live cultures are present at consumption.
Milk Allergy and Yoghurt
Yoghurt is a milk product and contains milk proteins that can trigger allergic reactions in susceptible individuals. Symptoms may include hives, swelling, digestive distress, or more severe responses. People with a diagnosed milk allergy should avoid yoghurt and opt for suitable dairy-free alternatives.

Fiber Content in Yoghurt
Plain yoghurt does not contain dietary fiber. Its effects on gut health are related to its probiotic content rather than fiber. Some commercial yoghurts may have added fibers or prebiotics, but standard plain yoghurt is fiber-free.
