"Finally, attention must be drawn to one of the most important consequences of colonialism on African development, and that is the stunting effect on Africans as a physical species. Colonialism created conditions which led not just to periodic famine but to chronic undernourishment, malnutrition, and deterioration in the physique of the African people. If such a statement sounds wildly extravagant, it is only because bourgeois propaganda has conditioned even Africans to believe that malnutrition and starvation were the natural lot of Africans from time immemorial. A black child with a transparent rib cage, huge head, bloated stomach, protruding eyes, and twigs as arms and legs was the favorite poster of the large British charitable operation known as . The poster represented a case of kwashiorkor—extreme malignant malnutrition. Oxfam called upon the people of Europe to save starving African and Asian children from kwashiorkor and such ills. Oxfam never bothered their consciences by telling them that capitalism and colonialism created the starvation, suffering, and misery of the child in the first place. There is an excellent study of the phenomenon of hunger on a world scale by a Brazilian scientist, Josue de Castro. It incorporates considerable data on the food and health conditions among Africans in their independent pre-colonial state or in societies untouched by capitalist pressures; and it then makes comparisons with colonial conditions. The study convincingly indicates that African diet was previously more varied, being based on a more diversified agriculture than was possible under colonialism. In terms of specific nutritional deficiencies, those Africans who suffered most under colonialism were those who were brought most fully into the colonial economy: namely, the urban workers."
