regularly. Which foods are good
sources of protein?
INTRODUCTION

Conservation of low quality roughages to food
and fiber for humans
Conservation of grains to high quality protein
and nutrients

DEVELOPMENT IN THIRD
WORLD COUNTRIES
Less sophistication of livestock
production
 Smaller sized units of livesotck
production
 Developing nations consume large
quantities of aquatic animals


Amount of protein is considerable less than
that consumed in Western nations
