Early-life nutrition is arguably the most critical determinant of future health. It
provides the energy and critical building blocks for all development, determines
our future tastes and eating behaviors, and supplies the crucial substrate for the
establishment of a healthy microbiome, now recognized as one of the most important
determinants of immune and metabolic health. Our diets are also an
increasing source of exposure to adverse elements in the environment, including
contaminants and pollutants in our food and water supply, which have greater
potential to affect human health early in life than at any other stage.
