If someone has gum disease and his gums frequently (or always) bleed when he eats, is he restricted to a liquid diet on Shabbos and Yom Tov?


The recently-published sefer Orchos Shabbos suggests that one whould be allowed to eat in this situation, based on Dagul MeRevavah (quoted by Mishnah Berurah 340:17, concerning the consumption of food with words written on it) who rules that a psik reishah d'lo nicha lei (unwanted consequential act) is allowed in a case where the result is damaging (m'kalkel) and the act is done in an unusual manner (k'lachar yad). He cites Rav Nissim Karelitz shlit"a as being lenient regarding this issue.

    It sounds like the basis is a derabanan with tarti l'rei'usa. How does it play out in this case where mekalkel is chayav? Now that you mention a psik reisha d'lo nicha lei, it should be very easy to permit this case since many poskim hold that that is mutar straightaway. – YDK Aug 29 '10 at 15:28

Perhaps it's a shvus (doesn't want it) d'shvus (netilas neshama isn't done with food) bemakom tzaar or mitzva. Although I don't know if that's the case when he's in pain/not oneg anyway.

There's probably a better answer.

  • "Netilas neshama isn't done with food" - why does that make it a shvus? – Dave Aug 29 '10 at 14:10
  • It's the equivelent of your k'lacher yad. It make the melacha a derabanan. – YDK Aug 29 '10 at 15:02
  • What you said is pretty close to what I found in Orchos Shabbos, except that his logic seems to apply even where there is no tzaar or mitzvah (due to the element of m'kalkel?). – Dave Aug 29 '10 at 15:22
