The culinary versatility of onion is no secret to the world. It is a must-have vegetable in almost every global recipe. But did you know that it also helps managing diabetes? A study, published in the journal Environmental Health Insights, found a link between fresh onion and reduced blood glucose levels in type-1 and type-2 diabetics. Hence, adding onion water in your diet may help benefit your overall health. Add 2 chopped onion, 1 teaspoon lemon juice and a pinch of rock salt with a cup of water and blend everything together and drink. Do not strain the drink to make it fibre-rich.
