Halakhah su Deuteronomio 8:9

And there are those among our rabbis whose opinion it is that the Torah obligated us to recite a blessing after all of the seven species, such as dates, wine and fig-cakes (see Berakhot 12a) - as it obligated us in truth to recite a blessing after those of them that are nourishing - and said that it was said about all of them, "And you shall eat and be satiated, and you shall bless" (Deuteronomy 8:10). And they also said that satiation from Torah writ it only with [as much as] a kabeitsah; as with this [quantity] the mind of a [hungry] person is put at ease. And I see a bit of proof for their words from that which they said at the beginning of the chapter [entitled] Keitsad (Berakhot 35a), in the give and take which is in the Gemara to find the obligation of blessing from the Torah: It is said over there, "Just as the seven species is something that has benefit and requires a blessing; so too, any item that has benefit, requires a blessing." It appears from this that there is no distinction in the seven species between those that give nourishment and those that do not, such that there is an obligation for blessing from the Torah for all of them. But in any event, I saw in Rambam, may his memory be blessed, (Mishneh Torah, Laws of Blessings 1:1 and see 3:12 and Kessef Misneh there) and others are with him, such that it appears to me from their words to say that the central obligation of blessing by Torah writ is only on being satiated in the eating of nourishing food, and not on other species, even if they are from the seven species; such as pomegranates, grapes, fresh figs and dates - since they are not nourishing. As the Torah only obligates on nourishing foods; and because of this, [it] put bread adjacent to the blessing - as it is written (Deuteronomy 8:9), "you shall eat bread in it," and then it reverts, "And you shall eat and be satiated." But we shall listen to the great ones in our generation concerning the laws of the Torah.
