If light is a particle, can it be eaten? Does light have calories?

Or alternatively, are we breathing in light particles into our lungs all the time?

Light isn’t a particle like a dust particle. In physics a particle means a unit that has consistent properties.

Imagine you have a long rope. You wave one end of it and a wave starts to travel down the rope. You can view that wave as a unit. A light particle is similar to a wave on a rope. But it has other weird properties so it’s not like a wave on a rope with minor changes in behavior.
