Oatmeal water (agua de avena) is a beverage created by extracting the soluble components from whole oats into water. It is derived by soaking or boiling oats and then straining the solids to yield a creamy, nutrient-infused drink. It serves as both a dietary supplement and a topical skin treatment.
Key Nutritional Components of Oatmeal Water
The most prominent component is beta-glucan, a form of soluble fiber that contributes to the liquid’s slightly viscous texture. This fiber is responsible for many of the internal health benefits associated with consuming oats.
Avenanthramides, potent antioxidants found almost exclusively in oats, possess anti-inflammatory properties that benefit the body internally and externally. Additionally, the liquid contains saponins, natural glycosides that contribute to a mild, soap-like cleansing action when applied topically.
Internal Benefits for Digestion and Circulation
When consumed, beta-glucan fiber provides support for cardiovascular health. This soluble fiber forms a gel in the digestive tract, binding to cholesterol and preventing its absorption. This promotes the excretion of low-density lipoprotein (LDL), reducing the risk of heart disease.
The gelling action of beta-glucans helps regulate the body’s glycemic response after a meal. By slowing the digestion and absorption of carbohydrates, the fiber helps prevent sharp spikes in blood sugar and insulin levels.
Oatmeal water supports a healthy digestive system, primarily due to its soluble fiber content. Beta-glucan acts as a prebiotic, feeding beneficial bacteria in the gut and promoting a balanced microbiome. This supports gut health and aids in maintaining digestive regularity, preventing constipation.
Topical Uses for Skin Soothing
When oats are finely ground and mixed with water, they create colloidal oatmeal, the active form used for skin care. This substance helps form a protective film on the skin’s surface, acting as a barrier to lock in moisture and prevent water loss.
The avenanthramides provide an anti-inflammatory effect that helps minimize redness and itching. This makes it useful for irritated skin conditions, including mild sunburn, dry skin, and eczema flare-ups. Furthermore, the saponins act as a gentle cleanser, cleaning the skin without causing additional irritation or stripping away natural oils.
Safe Preparation and Consumption Methods
Oatmeal water is generally prepared using one of two methods: cold-soaking or boiling. The cold method involves soaking rolled oats in water overnight, which allows the soluble nutrients to leach into the liquid. The boiling method involves simmering the oats briefly before allowing them to cool, which can sometimes extract more of the starches.
Regardless of the method, the mixture must be thoroughly strained through a fine-mesh cloth or strainer to remove the solid oat particles, leaving only the water-soluble components. Oatmeal water should be stored in the refrigerator and is typically best consumed within three to seven days of preparation.
For daily consumption, a common recommendation is to drink one to two glasses of the strained liquid. Individuals with gluten sensitivities should ensure they use oats that are specifically certified as gluten-free to avoid any cross-contamination. Adding natural flavorings like cinnamon or vanilla can improve palatability without adding excessive sugars.
