re you a food lover?
We are too. In fact, most people fall into one of two camps—
those who live to eat and those who eat to live. Te saying “you are what you eat” is
true in that part of the food we eat is converted to our living flesh. In other words,
our bodies use some nutrients to build cell structures, replace worn-out parts, and synthe-
size functional molecules. However, most nutrients we ingest are used as metabolic fuel.
Tat is, they are oxidized and transformed to
ATP
, the chemical energy form used by cells.
