how long until food is available as energy

jjpptt2

I'm sure there are a bunch of factors, but speaking in fairly general terms, how long does it take food to be digested/absorbed and available as energy?

Something like gatorade (liquid, primarily simple sugars) I assume is pretty quick.
Energy gels, slightly longer due to the consistency, but probably not meaningfully so?
Jelly beans or rice crispy treats (solid foods, but basically all sugar)?
What about something like a snickers bar (fats and sugars, solid food)?


Thanks.

I'm not sure if it being food or liquid makes a large difference considering that even table sugar needs to be broken down into components, and any solid foods are already pretty liquid through chewing and the chemical breakdown caused by saliva.

According to this article, they all occur within a few hours of each other, with carbohydrates (simple to complex) being the quickest (within an hour), then protein (1-2 hours), then fat (several hours). A large amount is going to take longer just because of volume.

Edit: These time estimates look like what it would take for the food to reach the small intestine, not to travel through the whole digestive track.

Thanks. Those numbers are slightly longer than what I've heard before, but not drastically so.
