The Ancient Elixir Gone Viral
From TikTok to Instagram, wellness influencers are showcasing their homemade fermented rice water, often called kanji, as a gut-friendly superdrink. This humble beverage is essentially the liquid left over after soaking cooked rice in water, left to ferment overnight
or for up to a couple of days. The result is a slightly sour, tangy liquid that is being hailed for a wide range of holistic health benefits, from boosting digestion to improving skin radiance. This social media phenomenon is reintroducing a practice that has been a nutritional staple in many cultures, especially in India and other parts of Asia, for centuries.
A Tradition Steeped in History
In India, fermented rice water is far from a novelty. It's a traditional food known by many names, including 'Pazhankanji' in Kerala, 'Pakhala Bhata' in Odisha, and 'Saddhi Annamu' in Telugu-speaking regions. Traditionally, leftover cooked rice was soaked in water, often in an earthenware pot, and left to ferment overnight. Consumed the next morning, sometimes with additions like buttermilk, shallots, or chillies, it was valued as a cooling, hydrating, and energy-providing meal, especially for farmers and labourers. This practice wasn’t just about avoiding waste; it was a time-honoured method of enhancing the nutritional value of a simple staple food.
Decoding the Health Claims
Modern wellness creators are promoting fermented rice water for a host of benefits, many of which echo traditional beliefs. The primary claim centres on gut health. The fermentation process fosters the growth of beneficial bacteria, such as Lactobacillus, making the water a natural source of probiotics. These probiotics are said to improve digestion, reduce bloating, and support a healthy gut microbiome, which is linked to overall immunity. Other touted benefits include increased energy, clearer skin, and even weight management support, with claims that the process enhances the bioavailability of vitamins and minerals like iron, calcium, and B vitamins.
What Does Science Say?
There is a growing body of scientific evidence to support some of these claims. The fermentation process does indeed create a probiotic-rich beverage. Studies show that fermenting rice increases its nutritional profile, enhancing minerals and breaking down anti-nutritional factors, which can improve nutrient absorption. The presence of probiotics, prebiotics (which feed good bacteria), and postbiotics (beneficial byproducts of fermentation) can contribute to a healthier gut environment. Some research suggests these properties may help with digestive issues like irritable bowel syndrome (IBS) and reduce inflammation. However, while many benefits are linked to probiotics in general, large-scale human clinical trials specifically on fermented rice water are still limited. Much of the evidence remains rooted in traditional use and smaller studies.
Should You Try This At-Home Elixir?
Incorporating fermented rice water into your diet can be a simple and inexpensive way to potentially boost your gut health. It is easy to prepare at home using leftover cooked rice and water. However, it's not a magic potion. The nutritional content can vary based on the type of rice, fermentation time, and preparation method. For most people, it's a safe and healthy addition to a balanced diet. It's a natural, whole-food-based drink that aligns with a focus on gut wellness. While it may not deliver miraculous transformations overnight, it represents a return to traditional food wisdom that prioritizes natural processes to enhance nutrition.
