Is there such a thing as פת מדינה?

Question

In Bereishit, Hashem said to Adam

בזעת אפך תאכל לחם

This would seem to imply that bread is universal to all people.

We also know that bread has a particular definition: it has to be made from one of the five grains. Bentching after eating bread (כדי שביעה) is a Torah obligation, so this is a Torah level definition (at least according to the accepted halacha, Rabbi Akiva in Berachot 6:8 says you can bentch on any full meal).

But there have been cultures that didn't have bread. The Aboriginal Australians, before European contact, had something called bush bread, but it was made from plants other than the 5 grains, at least according to their standard identifications. Although there is a kind of barley native to North America, it seems that most Native Americans (again, pre-European contact) made their bread from other crops, like corn.

For havdala, and possibly for kiddush and other purposes, we can use חמר מדינה instead of wine. The Rashbam (Pesachim 107a) says another drink can become חמר מדינה if there is no real wine in the city; the Rambam is more lenient and says that if the people primarily drink something else instead of wine it becomes חמר מדינה.

Is there a similar concept of פת מדינה, in a place where there is no bread made from the 5 grains? Would you be able to bentch on this "bread", or make kiddush on it according to those who say that חמר מדינה works for kiddush?

Answer 1

Since all people can from Adam and Adam ate bread, it is the bread of all people, if a group of people decided (to move to a different land and) not to eat bread, it does not change the definition of bread even if they decide to call it that (unless the Torah also calls it that)

Even goyim came that people did not always live in Australia and America they came there from places where bread grows

My understanding is that the drink of the media can be used, becouse that what is says in the law, but we do not say hagofen on it, and not the meain shalosh

The idea is that the rabbinic law to make havdolo on an important drink did not mean sposificly wine but the most important drink that is available (which has some importance) so wine was always preferable

The law is learnt from the Torah to make an after brocho on bread made from wheat or barely which the rabbis explain include the 5 types of grains, (which seem to be the only grains with glutain)

The idea of the drink of the country is regarding the drinks importance

But by bread (its importance is secondary) the legal thing needed is that it should be included in wheat and barley so the costom of the country should not change the law

Answer 2

Lechem in this context probably doesn't literally refer to bread alone.

You find other places in the Torah where Lechem was not a reference to bread but rather to life-sustaining food.

For example, The Monn which certainly wasn't bread was also referred to as Lechem

וַיִּרְא֣וּ בְנֵֽי־יִשְׂרָאֵ֗ל וַיֹּ֨אמְר֜וּ אִ֤ישׁ אֶל־אָחִיו֙ מָ֣ן ה֔וּא כִּ֛י לֹ֥א יָֽדְע֖וּ מַה־ה֑וּא וַיֹּ֤אמֶר משֶׁה֙ אֲלֵהֶ֔ם ה֣וּא הַלֶּ֔חֶם אֲשֶׁ֨ר נָתַ֧ן
