Red rajma, also known as red kidney beans, are high in fiber, iron, vitamins, and minerals, and are a good source of protein and carbohydrates. They are often used in Indian curries and salads, and can be eaten with rice for a healthy, protein-rich meal. Red rajma also has a low glycemic index, making it healthier for people with diabetes.

Rajma might help in reducing diabetes, controlling heart diseases, weight management and fighting against cancer. These potential effects need to be confirmed by further research and you should consult a doctor for health-related issues.
