Lecture Notes

The definition included on this slide of nutrition is from the American Medical Association, and it focuses mainly on the biochemical and physiological functions of food within our body.

So, I'll quote it here: "The science of food, the nutrients and the substances therein, their action, their interaction, and balance in relation to health and disease, and the process by which the organism ingests, digests, absorbs, transports, utilizes, and excretes food substances." So that's the definition of nutrition.

But simply put, when we talk nutrition, we're concerned with studying the food we eat, and how our bodies use this food for fuel. And so that's what we'll talk about for the rest of this lecture.
