To read the full abstract: Nature Communications 2018;9:636We know that good nutrition early in life has profound and long-lasting effects on body weight in later life. Malnutrition during pregnancy or infant formula feeding may be stored on the offspring genome as epigenetic memory and persist into adulthood, thereby influencing the susceptibility to metabolic diseases, such as obes...
