The simple onion has long been a staple in Indian kitchens, appearing in almost every household dish. Onions have been an essential part of our diet for centuries, used by our ancestors in age-old culinary traditions. For example, mixing leftover fermented rice with buttermilk, chopped onions, and chillies created a simple yet highly nutritious meal that supported digestion and overall health. This daily practice shows how onions were naturally integrated into a healthy diet long before modern nutrition science. Even today, in modern kitchens and Western cooking, onions remain ever-present, enhancing sandwiches, curries, stir-fries, soups, and more with their distinctive flavour, texture, and aroma. While we may take this everyday kitchen hero for granted, the onion offers remarkable Ayurvedic benefits that go far beyond taste. Let’s explore what Ayurveda has to say about this incredible bulb and the ways it can enhance our health and wellbeing.
