Dehydrated Potato Study

In partnership with the University of Arizona and with support from the U.S. Potato Board, an industry-funded group, Counterpart International (Counterpart) led a major study in maternal child health and nutrition clinics to develop a dehydrated potato flake and isolated soy protein food ration that can be used to treat malnourished children.

As a country, Senegal faces malnutrition levels as high as 17 percent of children under 5 years old (Human Development Index). The likelihood of becoming malnourished is exacerbated in the rural areas, where rainfall is limited, temperatures soar above 120 degrees Fahrenheit and food is scarce. Poor diets, low literacy rates and limited sanitation cause a general lack of education on proper nutrition for children.

Dehydrated potato products were blended with soy as a protein source and fortified with micronutrients to provide a similar nutrient profile to the well established corn-soy blend (CSB) product commonly used in food assistance programs. The new ration, called DPSB (dehydrated potato soy blend), is being compared to others used in rehabilitation clinics. The study's participants are children from 2-5 years old who attend Counterpart's USAID-supported maternal and child health and nutrition clinics or participate in our feeding programs.

Research Highlights:

• The potato-based product was culturally appropriate and equivalent to existing products in improved growth measures in the targeted group of children under 5 years old. There was no significant difference in weight gain between children who received the DPSB versus the CSB, which had an equivalent density of key micro-nutrients. It was determined that the DPSB was as effective for treating malnourished children as the CSB when provided as part of a home distribution food aid program. Children in both groups demonstrated catch-up growth during the four month follow-up period. 
• Results from the trial of dehydrated potato products in Senegal's National Agency for Little Children's Homes showed significant benefits to participating children, the most striking improvements appeared to be the impact on health markers, particularly diarrhea and school attendance. 
• Other positive benefits: dehydrated potato flakes were culturally acceptable and complementary to locally available food supplies while measurements proved that growth was maintained or improved in children consuming the products.
