The objective of this research has been identify an optimal combination of intake food items to satisfy the daily nutritional requirements by including millets. This research uses a modified form of the classic Diet problem. Using this mathematical model, an optimal combination of food items to be included in daily meal is found out. Apart from satisfying the nutritional need optimally, this research also takes into consideration to include the dietary preference of people. After solving for multiple scenarios, it has been concluded that that daily RDA cannot be fulfilled without including millets in the meal. Millets can have transforming impact on the nutritional intake of people and they can be highly beneficial in combating dietary nutrient deficiency.
