This special supplement of the Food and Nutrition Bulletin summarizes the most outstanding results of the INCAP Longitudinal Study. The unique cohort of this study is the longest followed since birth in a developing country. It is made up of people who, from conception or before they turned 7 years of age, participated as beneficiaries of a nutritional supplementation intervention during the period from 1969 to 1977 and who in the last follow-up (2015-2017) were men and women aged between 42 and 57 years. This is an intervention in that participants or their mothers when they were younger than 6 months of age, of 2 pairs of villages of the Department of El Progreso in Guatemala, were provided on demand 1 of 2 types of supplement: (1) an energy and proteinrich gruel called “atole” or (2) a low-calorie and nonprotein drink called “fresco.” Both supplements contained the same amount of micronutrients. In addition to the nutritional intervention, a health education program and primary healthcare assistance were provided, particularly aimed to mothers and young children. To date, this study has had 7 important followups over 50 years. The rigor with which the INCAP Longitudinal Study was implemented has generated strong and consistent evidence to support the need to invest in nutrition, health, and child care during the first 1000 days of life (from conception to 2 years) to achieve better childhood development, well-being, and human capital later in life. In addition, we are sure that there will be more follow-ups in the future, which will continue to provide invaluable knowledge to understand, prevent, and treat the most prevalent nutritional problems globally and their consequences on health, and even for the resolution of emerging nutritional problems. We have brought together a group of 12 worldwide prestigious researchers, who have contributed to the INCAP Longitudinal Study over several years, to prepare this commemorative supplement. In addition, 5 researchers in training who participated in the latest study follow-up (articles 4 and 7 in this supplement) and 2 researchers from the World Bank (last article in this supplement) were appointed, the later 2 to have an external perspective on the contribution of this longitudinal study to public health and nutrition globally. The authors of each article of this supplement have pointed out the main evidence with which the INCAP Longitudinal Study has
