(4) No - and if he does it for healing, it is permitted even if he is disgusted by it, as explained above in Siman 388, Seif 20. Even without healing, if it is something that is necessary for a person and the way of the world is to do this need with food, it is also permitted. For this reason, they sprinkle the ground with wine (for the aroma), smear the body with wine and oil (to soften the skin), as explained in the Gemara in several places. It is forbidden to injure olives to wash hands with water coming out of them (since they are strong and remove dirt) because the olives are made disgusting by this action and there is a loss of food (Gemara)

(7) (If it is) Full, etc. - But when it is not full, it is permissible to lean it (the bowl or pot) even though he uses bread. For a person can use bread for his needs, as we have said, and the same is true that it is permissible to cover a vessel with it [Tur].

(9) And do not throw bread - And it is explained in the Bais Yosef and Shaarei Poskim (other authorities) that bread is considered more significant than other foods, and it is forbidden to throw it even if it does not become disgusting through throwing. For example, if one throws it on a clean place, it is a disgrace (zilzul) to the bread.

(11) For example, nuts etc. - which are hard and do not crumble. And it speaks of when he threw them in a clean place, because otherwise it is forbidden even with nuts, as will be explained in seif (paragraph) 4. When we see food lying on the ground, it is forbidden to go and leave them there, but one must pick them up, unless in a place where there is reason to suspect witchcraft, such as a whole loaf (Eruvin 64). It is stated in the Gemara (Taanis 20) that Rav Huna holds: that human food should not be fed to an animal (and the same applies to birds). However, in the Elyah Rabbah it is doubtful whether the halacha follows Rav Huna in this matter, and see in the Machzis Hashekel who argues that if he has nothing else to feed, everyone agrees that human food is permissible, and perhaps for this reason people are accustomed to allow feeding birds bread.

(15) In place of a spoon - because a person can use his bread as he needs where it does not disgust (or ruin), and here it does not disgust this person since he himself ate the daisa (porridge) with it.

(16) And he should eat it etc. - because for another person it is disgusting, and there could be a loss of food.

(17) Those who are meticulous etc. - who are concerned about using a wooden utensil/spoon with food because it is a disgrace (bizui), therefore they eat a little bit of the bread [with the daisa (porridge) each time they put it in their mouths], so that appears as if he wrapped the (daisa in) bread.

(19) We draw wine through pipes/straws - which is done as a good sign, for their peace and goodness, and it speaks of a wooden tube that is not disgusting.

(20) And it is received - because otherwise there is a concern of loss of food.

(21) It makes them disgusting - Even though nuts have a shell and the food inside does not become disgusting, nevertheless during the rainy season when there is mud and dirt, they become dirty and disgusting to pick up and there is a loss of food. There are places where they have the custom today to throw dates in front of the groom on Shabbat before his wedding when they call him up for Maftir. And what they are doing is not appropriate/nice because they are soft and become disgusting through this.
