To combat malnutrition, the president of Zambia promised on pint of milk per days to each school-age child in the country. He soon found his promise impossible to keep. Thankfully, Alex Buchanan was able to help. It was the early 1970s, and Buchanan ('60 MS dairy bacteriology and agricultural economics) had recently developed nutritionally fortified biscuits that would help the president keep his promise. Promoted with the slogan, "eat more milk," an intense publicity campaign encouraged people to feed the nutritious biscuits to their young children. The president wore the ring-shaped cookies on a string around his neck, and Buchanan was photographed feeding them to his own daughter.
