This paper provides an evolutionary perspective on why modern complementary food diets are often inadequate, asserting that inadequate diets and nutritional deficiencies have likely been a part of the human condition since the agricultural revolution.

Mothers in the rural Boucle de Mouhoun Region of Burkina Faso had low levels of knowledge of IYCF and practices, according to this study: 60% of children had the minimum meal frequency, while only 18% benefited from the minimum dietary diversity and 13% received minimum acceptable diet.
