Oddly, I think how you track can matter here. If you do it as a lookup of "I am eating this, and it says it was this many calories" then you are not likely to remember and develop a sense of how many calories things have. However, if you do it as "I am eating this, I think it has X calories, but looking it up I found it was Y" that can help remember.

I can try to find the studies, but basically, "guess and check" is ridiculously powerful in learning. Is part of what makes flash cards so strong. Just "ask and answer", not so much.
