Brown rice water is the starchy liquid left over after cooking or soaking brown rice. It has several potential benefits for hair and skin. Here, we will explore the benefits of brown rice water, how to make it and potential risks and side effects to be aware of.
Health Benefits Of Brown Rice Water
Brown rice water, the nutrient-rich liquid, has been gaining attention in health circles. But is it just another passing fad, or does science back up its purported benefits? Let’s dive into the research and explore 12 evidence-based advantages of consuming brown rice water, along with practical tips to maximize each benefit.
1. Enhanced Digestive Health
Brown rice water is a digestive powerhouse, thanks to its high content of resistant starch. This indigestible carbohydrate acts as a prebiotic, feeding the beneficial bacteria in your gut.
A 2019 study published in the Journal of Nutritional Science found that resistant starch consumption led to significant increases in butyrate-producing bacteria, which are crucial for colon health.
But how does this work? When these good bacteria ferment resistant starch, they produce short-chain fatty acids (SCFAs), particularly butyrate. Butyrate is the primary fuel source for the cells lining your colon, helping maintain the integrity of your gut barrier. A 2021 review in the journal Nutrients highlighted butyrate’s potential in alleviating symptoms of inflammatory bowel diseases like ulcerative colitis and Crohn’s disease.
Want to supercharge these benefits? Try fermenting your brown rice water at room temperature for 12-24 hours before drinking it. This process allows beneficial bacteria to multiply, enhancing its prebiotic properties. For an extra gut health boost, pair your rice water with other fermented foods like kimchi or kefir.
Summary: Brown rice water supports digestive health by feeding good gut bacteria and producing compounds that maintain a healthy colon lining. Fermenting the rice water can amplify these benefits.
2. Blood Sugar Regulation
If you’re watching your blood sugar, brown rice water might be your new best friend. It’s rich in gamma-aminobutyric acid (GABA), a compound that’s been shown to have anti-diabetic effects. A 2017 study in the Journal of Functional Foods found that GABA stimulates pancreatic beta cells to release insulin, improving glucose uptake and utilization.
But that’s not all. Brown rice water also contains phytic acid, which slows down carbohydrate absorption in your digestive tract. This means a more gradual rise in blood glucose levels, preventing those dreaded sugar spikes. A 2018 study in the International Journal of Environmental Research and Public Health demonstrated that phytic acid consumption led to improved glycemic control in individuals with type 2 diabetes.
Here’s a pro tip: Add a splash of apple cider vinegar to your brown rice water. The acetic acid in vinegar has been shown to improve insulin sensitivity and reduce postprandial glucose levels. A small 2015 study in Diabetes Care found that consuming vinegar with a high-carb meal reduced blood sugar levels by 20% compared to the same meal without vinegar.
Summary: Brown rice water may help regulate blood sugar by promoting insulin release and slowing down carbohydrate absorption. Adding apple cider vinegar can enhance this effect.
3. Improved Hydration and Electrolyte Balance
Forget those neon-colored sports drinks – brown rice water is nature’s electrolyte solution. It’s packed with essential minerals like potassium and magnesium, which play crucial roles in maintaining proper hydration and fluid balance.
A 2021 study in the Journal of the International Society of Sports Nutrition found that natural electrolyte drinks like rice water were just as effective as commercial sports drinks in rehydrating athletes after intense exercise. The researchers attributed this to the optimal ratio of carbohydrates to electrolytes in rice water, which allows for rapid absorption in the small intestine.
But brown rice water isn’t just for athletes. Its isotonic nature makes it an excellent choice for anyone dealing with mild to moderate dehydration, whether from illness or a hot day. To maximize its hydrating potential, try adding a pinch of high-quality sea salt. This simple addition increases the sodium content, further enhancing the electrolyte balance and improving overall hydration.
