FOREWORD
Understanding the nature and dimensions of the world food problem and the policies available to alleviate it has been the focal point of the IIASA Food and Agriculture Program since it began in 1977.
Inadequate food consumption by a large number of people is the major food problem of the world. Though there is agreement among scholars that the prob- lem is widespread, estimates of the number of hungry people vary considerably.
Controversy also surrounds methods of estimating nutritional norms from data on household consumption surveys. Thus it is important to look at nutrient requirements from a physiological point of view.
Michel Loewik in this paper provides such a review of nutritional require- ments and diet.
