Programmes led by the World Food Programme operate within Tanzania. The Supplementary Feeding Programme (SFP) aims to target acute malnutrition by supplying blended food fortified with vitamins to pregnant women and mothers to children under 5 on a monthly basis. Pregnant women and mothers to children under 2 have access to the Mother and Child Health and Nutrition Programme's "Super Cereal" which is supplied with the intent of reducing stunting in children. World Food Programme supplementation remains the main food source for Tanzania's refugees. Super Cereal, Vegetable Oil, Pulses and Salt are supplied as part of the Protracted Relief and Recovery Operation to meet the average persons minimum daily caloric requirement of 2,100 kcal. UNICEF state that continued investment in nutrition within Tanzania is of the utmost importance: Estimates predict that Tanzania stands to lose $20 billion by 2025 if nutrition within the country remains at its current level, however improvements in nutrition could produce a gain of around $4.7 billion
