Rajgira flour, also known as amaranth flour, is a popular choice during Navratri fasting. It is naturally gluten-free and provides plant-based protein, carbohydrates for energy, and minerals such as calcium, iron and magnesium. Rajgira can be used to prepare rotis, cheelas and other traditional fasting dishes.

However, nutrition experts point out that gluten-free does not automatically mean healthier. A balanced fasting diet should include adequate protein, fibre, fruits, vegetables and fluids. Avoid excessive fried foods and overeating, and choose suitable portion sizes to maintain energy throughout the nine days.
