Often we see that economist and social scientist working on food security look up to food grains as the only source of food for humans. they often ignore the importance of non-vegetarian food as source of food. when most of humans in the world are non-vegetarian then ignoring non vegetarian source of food is a blunder while analyzing food security of a nation or region. Even I ignored the importance of non vegetarian sources of food in my presentation on food security http://www.slideshare.net/AgriGouravvani/food-security-in-india-myths-and-realities ,
