Is Cheese Bad for Acid Reflux?
Acid reflux, also known as gastroesophageal reflux disease (GERD), is a condition where stomach acid frequently flows back into the esophagus, causing irritation. Diet plays a significant role in managing acid reflux, and certain foods can exacerbate symptoms. This article explores whether cheese is one of those foods.
Acid-Forming Potential of Different Cheeses
Potential Renal Acid Load (PRAL) and Cheese Types
Cheese can have varying effects on acid reflux depending on its type and composition. The acid-forming potential of cheese is often measured using the Potential Renal Acid Load (PRAL) index, which considers the content of protein, phosphorus (P), chloride (Cl), sodium (Na), potassium (K), magnesium (Mg), and calcium (Ca).
- Fresh Cheese: Fresh cheese has a lower PRAL value, around -0.8 mEq/100g, indicating it is less likely to contribute to acid load in the body.
- Hard Cheese: Hard cheeses like Cantal and blue-veined cheese such as Fourme d’Ambert have higher PRAL values, 25.3 mEq/100g and 28 mEq/100g respectively, suggesting they are more acid-forming.
Impact of Lactate Content
Interestingly, despite their high PRAL values, hard cheeses are rich in lactate, which might make them less acidifying than their PRAL values alone would suggest. This means that while hard cheeses have a higher potential to form acid, their actual impact on acid reflux might be mitigated by their lactate content.
Probiotics in Fresh Cheese and Acid Reflux
Lactic Acid Bacteria (LAB) and Gastrointestinal Health
Fresh cheeses, particularly those produced with probiotic bacteria, can enhance the survival of beneficial lactic acid bacteria (LAB) through the gastrointestinal tract. These probiotics can potentially improve gut health and may help in managing acid reflux symptoms by maintaining a healthy balance of gut flora.
- Survival in Acidic Conditions: Fresh cheese has been shown to significantly improve the survival of LAB in acidic conditions (pH 2.5), which are similar to the stomach environment.
- Protection Against Gastrointestinal Juices: Fresh cheese also protects LAB against bile salts and pancreatic enzymes, enhancing their delivery to the gut.
Conclusion
The impact of cheese on acid reflux largely depends on the type of cheese consumed. Fresh cheeses, with their lower PRAL values and probiotic benefits, might be less likely to exacerbate acid reflux symptoms. In contrast, hard cheeses with higher PRAL values could potentially contribute to acid load, although their lactate content might offset some of this effect. For individuals with acid reflux, opting for fresh cheese and monitoring their body's response can be a practical approach to managing symptoms.
