While chana, rajma, and moong are good sources of protein, relying solely on them might not be sufficient to meet your daily protein needs, especially if you have higher requirements due to activity level or other factors. A varied diet is generally recommended.
Chana (chickpeas), rajma (kidney beans), and moong (mung beans) are legumes, and legumes are indeed a valuable source of plant-based protein. However, protein requirements vary based on individual factors like age, sex, weight, and activity level. A sedentary adult generally needs around 0.8 grams of protein per kilogram of body weight per day. Active individuals or those looking to build muscle may need more.
To determine if these legumes alone are sufficient, you need to calculate your daily protein needs and then estimate the amount of protein you're getting from a typical serving of chana, rajma, and moong. While they contribute significantly, they might not provide the complete amino acid profile or the total quantity required. Furthermore, relying on a single food group can lead to nutrient deficiencies. It's best to incorporate other protein sources like lentils, tofu, nuts, seeds, dairy (if you consume it), or meat/fish/poultry (if you consume them) to ensure a balanced intake of all essential amino acids and other vital nutrients.
Combine legumes with grains like rice or quinoa. This combination creates a complete protein, as grains provide the amino acids that legumes are lower in, and vice versa, maximizing the protein's usability by your body.
