These types have this attitude of not minding such "trivialities", however, Subdued Si translates in taking it condescendingly (from someone else), while Valued Si in welcoming that someone thinks about it. It is up to you to tell which is the case, just make sure you don't take this too literally and think about cases in your real life.
Besides, Si is not only about food and body sensations, that is an very small part of it - and one of the greatest misinterpretations among Socionics enthusiasts. Si is rather the precise perception of limits, requirements, consequences and necessities (in everything!), what we can do and what we can't. What we need in order to do something, and if we have it satisfied. What necessarily (not possibly!) happens if we do this or that. I strongly believe that I won't ever be able to find one Si Ego to believe in such things like mind over body, meditation to have a greater strength, or resist cold or hunger for large periods of time. And this is not strictly about the human body, but about how things work.
