>We care quite a lot about the form energy takes not just absolute quantities.

Yes, I've already mentioned this:

>However, we shouldn't assume health and diet are simply a matter of calories as input.

In the context of the discussion, it's an error IMO to compare energy as if they are interchangable. People aren't just consuming beef just for it's caloric value. The "form" of energy (protein & fat) is an important consideration too.

>In comparison with bio fuels, green hydrogen

The constant digression of a topic focused on nutrition into one merely about energy makes for a tiresome conversation and largely misses the point. Just because you can make a loose connection with the topic at hand doesn't mean that discussion is relevant.
