Being the most populous countries of South Asia, India, Pakistan and Bangladesh together represent about 37% of the world total undernourished population. In the article, there are calculated the expenditure elasticities and the own and cross non-compensated price elasticities of main vegetable products of these countries by using the LA-AIDS model. Th ere are used the elasticity estimates to decompose the recent demand fl uctuations into price eff ect, income eff ect and population eff ect for each country. Th en the ways for the government to improve the protein and energy intake after cal- culating the vegetable protein and calories elasticities are compared. Wheat and rice in these countries are relatively price inelastic. For these three countries, the population development (as well as the revenue for India and Bangladesh) appears to be the most important and regular cause of the augmentation of demand for vegetable products. A combination of in- come and price policies may be more eff ective in infl uencing the consumption pattern. Th e government should aim at im- proving the income level of most vulnerable consumers (low income group) in these countries.
