On what basis is the significance of pulses understood in a low-cost diet?

Correct answer: They can be an affordable source of plant protein

Pulses such as lentils, beans, peas, and chickpeas are important in a low-cost diet because they provide substantial plant protein at a relatively affordable price. They may also supply complex carbohydrates, fibre, iron, and other nutrients. They do not cure every disease or replace all foods, so option A is the only accurate and appropriately qualified answer.
