Avos D’Rebbi Nassan 26:5 says (translation is from Artscroll, and brackets are from their footnotes):
הוא היה אומר האוכל אוכלין שאינם עולים על גופו עובר משום ג' לאוין שביזה את עצמו וביזה את האוכלין ומברך ברבה שאינה כתיקונה
He used to say: One who eats foods that do not agree with his body [that is, he eats food that is repulsive to him] commits three transgressions: (1) He has demeaned himself [i.e. he has caused himself to become disgusted, and thereby transgressed the prohibition (Leviticus 11:43), Do not make yourselves abominable], (2) he has degraded the foods that he ate [and thereby violated the prohibition (Deuteronomy 20:19), Do not destroy... This applies to any destructive or wasteful act. Since a different person who is not repulsed by the foods could have benefited from them, this person is considered to have wasted food], and (3) he has recited a blessing improperly.
I’d never heard of this before, and as such, was wondering if this Braisa is ruled in Halacha.
- Is one really not supposed to make a Beracha on food one doesn’t like? If so, if one eats a particular food for the first time and therefore isn’t sure if he will like it or not, should he make a Beracha, since we’re lenient on a doubt by Berachos (or, perhaps, eat another food he does like that would have the same Beracha)?
- Are parents in violation of לפני עור for feeding their kids food they don’t like (read: vegetables)?
Particularly for the second question above leaves me wondering whether we don’t pasken like this Braisa. Looking for actual sources in the Poskim.
