INTRODUCTION
The rise in overweight, obesity and malnutrition
worldwide is a major public health challenge.
Malnutrition is a major contributor to the total global
disease burden. In a few developing countries, up to
20% of children under-five are overweight (WHO, 2009).
Citizens in developed countries can afford to purchase
food. Without considering the nutrients requirement,
spending much money cause over nutrient that will harm
to our body system. For example consuming high
amount of fat, cholesterol and sugar exposes people to
obesity, high cholesterol, or diabetic.
Raffensperger (2008) discussed that the least-cost of
low-carbohydrate is more expensive than the least-cost
of low-fat diet. The study also identified which nutrients
had the greatest effect on cost for a low-carbohydrate
and low-fat diet.
Meanwhile Cadenas et al. (2004) employed the fuzzy
optimization to diet problems in Argentinean farms. It
used a Decision Support Systems (DSS) named SACRA
(a Spanish acronym for support system for the
construction of cattle diets) that specially developed for
the problem.
Htun et al. (2005) examined the effect of dietary protein
quality on the black tiger shrimp and how food
consumption and diet quality can affect the shrimp
growth and survival. The used model can predict
population of the shrimp under shrimp aquaculture
conditions. It presented simple models for describing
and predicting growth and feed requirement of black
shrimp under shrimp aquaculture conditions.
Raffensperger (2008) has proposed the model of
Minimize Cost Diet Problem (MCDP) as the following:
