Nutrition is traditionally a multidisciplinary field applying principles of
molecular biochemistry and statistical epidemiology to integrative metabol
ism and population health. Genomics, with its global perspective, is now re
inventing the future of human metabolic health. Creative experimental desig
ns are addressing metabolic questions in nutrition ranging from energy regu
lation to aging, and from mechanisms of absorption to the interspecies mole
cular crosstalk of bacteria and human cells within the intestine.
