The Science Behind Curd and Acidity
Curd is a fermented dairy product containing probiotics, beneficial bacteria that support a healthy gut microbiome and efficient digestion, which can help prevent acidity. The cool, thick texture of fresh curd can also temporarily soothe the burning sensation of acidity by coating the stomach lining. However, the fermentation process produces lactic acid, making curd acidic. As curd ages and becomes sour, its acidity increases, potentially irritating a sensitive stomach. High-fat dairy can also relax the lower esophageal sphincter, allowing stomach acid to flow back into the esophagus and worsen GERD symptoms.
When Curd Helps with Acidity
- Probiotics: Aid digestion and support a balanced gut, reducing acidity.
- Soothing Effect: Fresh curd can provide temporary relief by coating the stomach lining.
- Efficient Digestion: Contributes to a healthier gut microbiome, reducing excess gas and stomach acids.
When Curd Can Worsen Acidity
- Sour or Aged Curd: Higher acidity can irritate the stomach lining.
- High-Fat Content: Can relax the lower esophageal sphincter, increasing reflux risk.
- Incorrect Timing: Eating curd late at night can slow digestion and increase fermentation.
A Comparison: The Good, the Bad, and the Buttermilk
| Feature | Fresh Plain Curd | Aged Sour Curd | Buttermilk (Chaas) | 
|---|---|---|---|
| Effect on Acidity | Generally beneficial and soothing | Can trigger or worsen symptoms | Very beneficial, cooling, and lighter | 
| Probiotic Count | High | High, but acidity may outweigh benefits | Good | 
| Acidity Level | Moderately acidic, but alkaline-forming effect once consumed | Highly acidic due to prolonged fermentation | Low, diluted with water | 
| Fat Content | Varies, low-fat is best | Varies | Low-fat, light on the stomach | 
| Best Consumption Time | Afternoon or with lunch | Should be avoided by those with acidity | Afternoon, especially after lunch | 
Best Practices for Consuming Curd with Acidity
To make curd a digestive ally, choose fresh, plain curd in moderation, consumed during the day. Buttermilk is a lighter alternative. Pair curd with compatible foods like cooked grains or non-citrus fruits, and avoid incompatible combinations that cause bloating and gas. Always listen to your body and adjust consumption as needed.
What to Avoid: Common Curd Pairings that Trigger Acidity
Certain combinations with curd can trigger acidity. Avoid mixing curd with raw onions, spicy or fried foods, citrus fruits, and high-water content fruits like watermelon or cucumber. Excessive processed sugar can also disrupt gut bacteria and slow digestion.
Conclusion: The Final Verdict on Curd for Acidity
The impact of curd on acidity depends on several factors. Fresh, plain, low-fat curd consumed during the day can be beneficial due to its probiotics and cooling effect. However, aged or sour curd, high-fat versions, or incompatible food pairings can worsen symptoms. Mindful consumption and listening to your body are key. Buttermilk is often a safer alternative. For persistent acidity, consult a healthcare professional.
