Red kidney beans (or rajma) are a staple in Indian cuisine and are also widely used in Mexican and Brazilian cooking. They can be enjoyed in gravies, curries and salads. Rajma is rich in both soluble and insoluble dietary fibre, which helps lower cholesterol, aid digestion and regulate blood sugar. It is a protein-rich food that provides ample amounts of essential vitamins and minerals like B1, calcium, potassium and manganese, as well as antioxidants.
