Proteins

Its protein contents are 3.5 times that of rice and 2.5 times that of wheat. It provides an excellent source of protein, particularly for those adopting vegetarian diets or diets which do not contain much meat. It is typically around 25% protein by dry weight, giving it a comparable protein content to meats. However, by weight, cooked (boiled) dal contains 9% protein, 70% water, 20% carbohydrates (includes 8% fiber), 1% fat.[1] Note that as extra water is added to cooked dal, as in the case of Sambar, proportion of proteins and other nutrients will reduce further. Protein contents of cooked Dal[2]are one third that of cooked chicken.[3] Most Dals (except Soybean, being exceptionally higher) have similar amount of protein. Within vegetarian group, only Soybean has complete protein (has constituent amino acids in right proportions). All other Dals including Toor Dal do not have individual amino acids within protein in ideal proportion (unlike, eggs and meats). However, if Dal is eaten with rice or wheat(roti), it provides, amino acids in the right proportions making it complete protein. ( See Protein combining). Bioavailability of proteins from Dals is less than those from eggs and meats.
