The challenge of meeting nutrient needs of infants and young children during the period of complementary feeding: an evolutionary perspective

August 11, 2020

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. Preagricultural humans likely had higher intakes of key nutrients, and the author concludes that in low-income countries, where resorting to a preagricultural, non-cereal based diet is not an option, other sustainable strategies for nutritional adequacy must be developed.
