Oat water is a gentle yet highly effective remedy recommended for irritated stomach, acidity, heartburn, reflux, or slow digestion. This liquid obtained by soaking oat flakes has a soothing, emollient, and protective action on the gastric mucosa, supported by numerous studies in the field of phytotherapy and nutrition.
What Does Oat Water Contain?
Oat flakes contain:
- Beta-glucans – soluble fibers with anti-inflammatory effects
- Mucilages – form a protective film on the stomach walls
- Avenanthramides – antioxidants with anti-irritant effects
- Easy-to-digest plant proteins
- Magnesium, zinc, vitamins B1 and B5 – support the recovery of irritated tissues
How Does It Act on the Stomach?
- Soothes the irritated gastric mucosa
Oat water coats the stomach walls, reducing the sensation of burning, pain, or discomfort. - Regulates acidity
Soluble fibers absorb excess gastric juices and create a more balanced pH. - Accelerates recovery after mild gastritis
Beta-glucans and minerals from oats help regenerate the irritated mucosa. - Slows down the digestion of carbohydrates
Thus, it reduces bloating and the feeling of abdominal pressure.
