Number of people who cannot afford a nutrient adequate diet
The cost of a nutrient adequate diet is the lowest-cost set of foods available that would meet nutritional requirements of calories, protein, fats and all essential vitamins and minerals. A diet is defined as unaffordable when its cost, plus basic non-food needs like housing and transportation, exceeds daily income.
