> First, these are two separate thoughts

Sure they are, sorry for mixing them up. Food for me represents both. Eating an avocado toast in the morning both makes me happy and gives me energy that I will use until around 12-13

> Do you understand it to be of short-term (i.e. energy levels before lunch) or long-term importance?

Both: short term as in energy needed during the day, and long term from a psychological point of view. This is subjective, of course.

Actually "proper nutrition" and "enjoyment of food" are closely related. Although our bodies are selfish. For example, we like sugar so much because it's good yet used to be scarce. Now we finally can get plenty of it, but our body gets greedy and we overeat it.

I don't think that is the case for the vast majority of people. If I would only eat according to my "enjoyment of food" I would probably only eat cake and chocolate.

I don't do that, of course, because I value "proper nutrition" for my body above my "enjoyment of food". I see relatively few people around me that would take broccoli over cake if they are eating for "enjoyment of food".

That's what I said in 2nd part of my comment. We still crave for sugar which was hard to get. And our bodies are greedy and abuse it. Yet historically it was needed for proper nutrition.

Broccoli may suck, but there are lots of tasty veggies. I love to snack on fresh carrots or cucumbers. Don't get me started on how tasty nuts or berries are...

For me, it's the opposite. Of course I enjoy snacks, but I'd rather prefer to eat something both tasty and healthy. I'd prefer carrots and hummus to a cake 99% of the time
