yes we do

Question

Do we acquire the energy located in our food when we eat it?

The eating of the food is just the first step in extracting the energy.

Since this is not my area of expertise, I searched Google under the key words "digestion" to get these possible sources:

http://www.kidshealth.org/kid/body/digest_noSW.html
http://www.nutristrategy.com/digestion.htm

I hope this helps a little more. Thanks for asking.
