I think that the concept of energy density makes sense if it is used as a
pair with nutrient density. I general it makes sense to eat nutrient dense
foods instead of energy dense foods. But there are exceptions of this rule,
as you mentioned. There are some studies to support eating nutrient dense
foods and avoiding energy dense foods. Eating energy dense foods has been
associated with weight gain in some studies. On the other hand eating
nutrient dense foods is associated with longevity in elderly people.

Density refers to the amount of something, nutrient or energy here, per unit
weight. I remain unconvinced that the concept of "density" with respect to
foods in the diet has any merit whatsoever.

It's just that one of the things that satisfies in a meal is stomach
fullness, and so the less energy you ingest to achieve this, the
better. Assuming you are getting a balanced diet. jack

But there is no evidence that weight is what makes you feel full. Volume has
some evidence in its favor, but not weight.


Aren't weight and volume much the same for most foods?
What food varies much from the specific gravity of water?
As weight is easier to determine with solids, that is what is usually
used, but yes, volume would be more accurate if such accuracy was all
that necessary here. jack

They are very different. Compare a liquid (milk, olive oil, tea) with dry
foods like bread or oat bran. Weight is not the same as volume. There is no
basis for the claims made for energy and nutrient density.
