Food is a basic necessity of life. A balanced intake of carbohydrates, fats and proteins constitutes the ideal diet. The body also requires other essential vitamins and minerals which can be obtained from various food sources and salt. The energy provided by food is measured in units called calories. The calories required by each individual depend upon the individuals height, weight, age and gender. On average, however, the ideal Pakistani diet should provide 2550 calories per head. Since 1992-3, the food available in Pakistan has been sufficient for the food needs of the country through the heavy import of wheat, edible oils and milk products. In view of the rapid population increase and the decline of the economy, Pakistan has to seriously consider how it will feed its population in the future.
Unfortunately, the food available in the country is not equitably distributed. The poor in Pakistan do not eat a sufficient quantity of meat, eggs, milk products and fruits to maintain a balanced diet. Many suffer from malnutrition.
