Nutritional deficiencies are due to inadequate amounts of particular categories of food and nutrients in what you have to eat and drink. All of the conditions here involve essential nutrients without which you cannot survive. You need large amounts of protein and carbohydrates, and small amounts of minerals and vitamins. Fats are essential to obtain some vitamins from food. Nutritional deficiencies are the sum of the following (with their contribution to the total nutritional deficiency deaths in 2002):
1. Starvation [Protein-energy malnutrition], Map 412, (54% of deaths).
2. Iodine deficiency, Map 413, (1% of deaths).
3. Vitamin A deficiency, Map 414, (5% of deaths).
4. Iron-deficiency anaemia, Map 415, (28% of deaths).
5. Other nutritional disorders, no map, (12% of deaths).
Nutritional deficiencies caused 0.85% of all deaths worldwide in 2002, an average of 78 deaths per million people per year.
