How much protein is in 100g of boiled rajma?

3 min read

According to USDA data, 100 grams of boiled kidney beans, or rajma, contains approximately 8.7 grams of protein. This makes boiled rajma a significant and accessible plant-based protein source for vegetarians and vegans.

Quick Summary

A 100g serving of boiled rajma offers about 8.7g of protein, along with significant fiber and essential micronutrients. Learn how to maximize its nutritional value.

Key Points

  • 8.7g Protein: A 100-gram serving of boiled rajma contains approximately 8.7 grams of high-quality plant-based protein.

  • Incomplete Protein: Rajma is not a complete protein on its own and should be combined with grains like rice to provide all essential amino acids.

  • Preparation is Key: Soaking and thoroughly boiling rajma is crucial to deactivate harmful toxins and improve digestibility.

  • Fiber Rich: Besides protein, boiled rajma is packed with about 6.4g of dietary fiber per 100g, which aids digestion and promotes satiety.

  • Boost Absorption: Pairing rajma with Vitamin C-rich foods like tomatoes or lemon enhances the body's absorption of its non-heme iron.

Protein Power: The Nutritional Breakdown of Boiled Rajma

Boiled rajma, a staple in many cuisines, is more than just a delicious component of classic dishes like rajma chawal. It is a nutritional powerhouse, particularly valued for its high protein and fiber content. For individuals following a vegetarian or vegan diet, understanding the protein contribution of staples like rajma is essential for meeting daily nutritional requirements.

The Specifics: Protein in 100g of Boiled Rajma

As confirmed by nutritional data, a standard 100-gram serving of boiled rajma contains around 8.7 grams of protein. This impressive amount of plant-based protein helps support muscle repair, growth, and overall body function. It's an affordable and nutrient-dense alternative to animal proteins, providing satiety and contributing to a balanced diet.

Full Nutritional Profile of 100g Boiled Rajma

Beyond protein, boiled rajma offers a wealth of other vital nutrients. A 100g serving contains approximately:

  • Calories: 127 kcal
  • Carbohydrates: 22.8 g
  • Dietary Fiber: 6.4 g
  • Fat: 0.5 g
  • Water: 67%

Boiled rajma is also rich in essential vitamins and minerals, including:

  • Folate (Vitamin B9)
  • Iron
  • Phosphorus
  • Copper
  • Magnesium
  • Potassium
  • Zinc

Raw vs. Boiled Rajma: A Nutritional Comparison

The cooking process significantly alters the composition of rajma. Boiling makes the beans safe to eat by deactivating harmful lectins, and also causes them to absorb a large amount of water, which affects the protein density per 100 grams. A comparison highlights these changes:

Feature Raw Rajma (approx. per 100g dry) Boiled Rajma (approx. per 100g)
Protein ~24-25g ~8.7g
Carbohydrates ~60g ~22.8g
Calories ~333 kcal ~127 kcal
Water Content Low High (~67%)

It is crucial to note that while the protein appears lower in boiled rajma per 100g, this is due to the weight gained from water absorption. The overall protein content of the cooked beans (starting from a dry weight) is still very high.

Making Rajma a Complete Protein Source

Rajma, like most legumes, is an 'incomplete protein,' meaning it lacks sufficient amounts of certain essential amino acids, particularly methionine and cysteine. However, by combining it with a complementary protein, you can create a 'complete protein' meal that provides all the essential amino acids the body needs. A classic example of this is the traditional combination of rajma and rice, a pairing that ensures a complete amino acid profile. Other combinations include pairing rajma with quinoa or whole wheat bread.

Tips for Maximizing Protein Absorption from Rajma

To enhance your body's ability to absorb the protein and other nutrients in rajma, consider these preparation techniques and pairings:

  • Soak Before Cooking: Soaking dried rajma overnight significantly reduces anti-nutrients like phytic acid, which can hinder mineral absorption. Always discard the soaking water and use fresh water for boiling.
  • Cook Thoroughly: Raw or undercooked rajma contains a toxic lectin called phytohaemagglutinin (PHA). Proper boiling is essential to destroy this compound and make the beans safe and digestible.
  • Pair with Vitamin C: The absorption of non-heme iron from plant sources like rajma can be significantly improved by pairing it with a source of Vitamin C, such as a squeeze of lemon juice or tomatoes in your curry.
  • Include Digestive Spices: Adding spices like cumin (jeera), asafoetida (hing), and ginger during cooking can aid digestion and reduce potential gas or bloating issues.

Conclusion

In conclusion, 100g of boiled rajma provides a respectable 8.7g of high-quality plant-based protein, along with an abundance of fiber, vitamins, and minerals. When prepared correctly by soaking and thoroughly cooking, it is not only a safe and healthy addition to your diet but also a cornerstone of a balanced vegetarian or vegan meal plan. By pairing it with a complementary grain like rice, you can create a complete protein source, maximizing the nutritional benefits for muscle health, weight management, and overall well-being.

Frequently Asked Questions

There is approximately 8.7 grams of protein in 100 grams of boiled rajma, making it a valuable plant-based protein source.

No, rajma is an incomplete protein. It lacks sufficient amounts of certain essential amino acids. However, combining it with grains like rice creates a complete protein meal.

Boiling does not significantly reduce the protein content of rajma, but it does cause the beans to absorb water, which lowers the protein concentration per 100 grams compared to raw, dry beans.

Eating undercooked or raw rajma can be harmful due to a toxic lectin called phytohaemagglutinin. This can cause severe gastrointestinal distress, including nausea, vomiting, and diarrhea. Proper, thorough cooking is essential.

To improve digestion, soak rajma for 8-12 hours before cooking, discard the soaking water, and cook thoroughly. Adding digestive spices like cumin and ginger can also help. Portion control is also important.

Rajma is beneficial for heart health due to its fiber content, helps manage blood sugar because of its low glycemic index, supports weight management by promoting fullness, and provides a good source of iron and other minerals.

While rajma can significantly contribute to daily protein needs, it is best to consume a variety of protein sources for optimal nutrition. Overconsumption of any single food can lead to imbalances.
