OK. Thanks bengurionji for providing the inputs.
Proteins are made up of smaller units called amino acids. There are about 20 different amino acids, essencial eight of these must be present in a healthy diet, all of which you have mentioned by name in your post.
You are absolutely right - unlike animal proteins, plant proteins may not contain all the essential amino acids within a single source. So just the kidney beans or just the broad beans may not have all types of amino acids.
But remember no sane vegetarian eats just daal or just rice or just the rotis or just drinks milk. A normal vegetarian diet includes a mixture of at least pulses-bread-rice and vegetables. This mixture makes up for all the essential amino acids you have mentioned. Combining plant proteins, such as a grain with a pulse, leads to a high quality protein which is just as good, and in some cases better, than protein from animal foods. (By the way, if someone considers Milk as vegetarian - then he should not have any issue at all with protein diversity - since milk and milk products are as rich in protein as meats).
Also, excess dietary protein may lead to health problems too! One of the benefits of a vegetarian diet is that it contains adequate but not excessive protein.
Another very important point. While you did mention, righly, about chicken meat being well-packed with protein in all types of amino constituents - You chose to ignore other contents of chicken meat.
Important one being <b>CHOLESTROL</b> the bad one. A serving of 145 grams of chicken meat contains as much as 641 mg of cholestrol, while the serving of the same amount of daal, rice, roti or vegitables has NIL or negligible cholestrol, in fact some good cholestrol.
Another very important thing to compare. The same serving size of chicken meat has absolutely NIL dietary fiber, resulting in other hazards. On the contarary, the vegetarian diet is such a rich source of the same.
Now about the price and economy. Let me do some research and get back to you.
