For example, a study found that the consumption of rajma led to decreased body mass index (BMI), body weight, and waist circumference in overweight and obese adults. It also led to more significant weight loss and improved lipid profiles in overweight and obese individuals compared to a control group. Additionally, research shows that regular intake of white kidney beans has been shown to induce weight loss in obese individuals.

Other Health Benefits of Rajma 

Rajma, or kidney beans, is a nutritious food that offers several health benefits beyond just aiding weight loss. Therefore, as per a study, increasing the consumption of beans is beneficial. Below are the advantages of consuming Rajma and how it can contribute to overall health.

Good for Heart Health

Rajma is rich in dietary fibre, protein, vitamins, and minerals, which can benefit heart health. A study found that regularly consuming kidney beans lowers LDL cholesterol, improving overall heart health. In addition, kidney beans have low saturated fat and protein content, contributing to a healthy heart. Moreover, the potassium in kidney beans promotes better heart muscle activity, improving heart health.

Cancer Prevention

Consuming Rajma can also lower the risk of certain cancers, such as pancreatic and colon cancer. Rajma is high in fibre, which promotes anti-cancer actions in the gut. The bacteria in the colon ferment the fibres, causing the development of chemicals that lower the risk of colon cancer. According to a study, regular consumption of Rajma reduces the risk of colorectal polyps by a similar method.

Controls Metabolism

Metabolism is the chemical process that occurs in the cells of an organism. Specific proteins regulate these processes, such as transforming food into energy, allowing you to perform activities such as moving, thinking, and growing. According to a study, consuming kidney beans improves overall metabolic health, aiding in regulating the chemical reactions in our bodies.

Enhances Memory

Rajma contains vitamin B1, which contributes considerably to optimal cognitive functioning. Vitamin B1 synthesises acetylcholine, an essential neurotransmitter that promotes healthy brain function and improves focus and memory. Furthermore, a study reveals that consuming Rajma delays the negative impacts of Alzheimer’s and dementia.

Nutraceuticals for Human Supplementation

Beans can be a good source of nutraceuticals for human supplementation, mainly compounds that disappear with cooking conditions but exhibit crucial biological activity. These nutraceuticals aid in fighting some of the significant health issues of our time, including obesity, cardiovascular diseases, cancer, osteoporosis, arthritis, diabetes, cholesterol, and more. A study reveals that increasing the consumption of beans is beneficial, which could be due to the presence of nutraceuticals.


Rajma’s numerous health benefits make it an excellent addition to any diet. Its cholesterol-lowering properties, anti-mutagenic and anticancer effects, prevention of obesity and lifestyle diseases, and enhancement of heart health, metabolism, and memory are some of the many advantages of consuming Rajma.

Rajma Consumption: Potential Side Effects

Harmful Chemical Component

The covering of uncooked Rajma contains a hazardous chemical component known as phytohemagglutinin (PHA) and lectins, which can harm gut health. As a result, vomiting and diarrhoea may occur. To avoid these side effects, it is recommended to soak Rajma for at least 5 hours and fully prepare them by boiling them for at least 30 minutes.


Antinutrients in rajma can reduce the nutritional value of other foods. In addition, substances such as protease inhibitors and starch blockers may impede digestion by inactivating various digestive enzymes. However, soaking the beans before boiling them can swiftly remove these chemicals. Therefore, soaking them for 30 minutes is sufficient.


Overeating rajma can lead to gas, constipation, and bloating. Therefore, watching portion sizes while cooking rajma is essential to avoid these side effects. Moreover, consuming too much of any food can result in weight gain, so it is crucial to eat in moderation.


Rajma is a nutrient-dense food with numerous health benefits when consumed in moderation. However, to avoid potential side effects, it is essential to soak and cook the beans thoroughly and watch portion sizes. Additionally, a healthcare professional or registered dietitian can help you ensure your diet is well-balanced and meets your nutritional needs.
