If a person could buy Pat Yisrael should he refrain from buying Pat Palter?

ב"ה S halom In the Shulchan Aruch (יורה דעה סי' קיב:א-ב ) the Mechaber writes that in "she'at Hadchak" meaning in difficult circumstances, one may eat Pat Palter , or what is called Pat Nachtom, when no other bread is available. This is what Sefardim should follow. However, Rav Ovadia Yoseph zt"l in Yechaveh Da'at (חלק ה' סי' נג ) pointed out that in many Sefardi communities Pat Palter was eaten even where the was Pat Yisrael, simply because there wasn’t enough Pat Yisrael. According to the Rema (Shulchan Aruch ,ibid) Pat Palter may be eaten even where there is Pat Yisrael and the Shach writes that this is the minhag which became widely accepted. So Ashkenazim may follow this ruling. However, the Pat Palter must have kosher ingredients and it is not to be assumed automatically that this is the case. Furthermore, as you know, the law is not the same in for bread baked privately by a non-Jew. All the best
