efsher some food or maybe just money

gemara last night was discussing mishloach manos and matanos le'evyonim. so why do we give money to the poor? it says you should give mishloach manos ish lreayhu ushtay matanos lshtai aniyim. or something very similar to that. so rashi says manos is delicacies, and then the gemara continues witha story of r ushiya receiving a gift of a cow and barrel of wine from i beleive his son, and he says now you have been mekayim the mitzvah of shaloch manos. well whats the chidush? so the ritvah says the story rerally was first he sent a leg of a cow and a barrel of wine and it was sent back to him and then he sent the whole cow. but rashi didnt learn that girsah. so according to ritvah you have to send something that is befitting the person you are sending to. so if your sending to the rav or to any adult for that matter dont send 7 raisins and 6 popcorns. your not yotze the mitzva. the next piece of gemara discusses that rava sent to mari through abaye some sweet kernels and something else, so abaye says when you're a simple villager thats ok to send but now your the rav of pumpidisa you have to send something nicer, so now we se that you also have to send something thats is befitting to yourself. so the real question is why send shaloch manos, is it to be friendly or is it to help someone with their meal? so now to the gift to the poor. if its to make friends then send him a some food and if its for a meal send better food. but we dont send better food to a poor person because it says matanos not manos. a poor person just wants a piece of bread not a duck a lamode. he wouldnt know what to do with all the feathers so to the poor person you give a small thing that he can eat to the rich person you send manos , a nice basket with nice things in it. so the question is still money or food to the poor? we couldnt find a reason why all of the sudden in the shulchan aruch he went from food to money. we couldnt see why we dont give food to the poor but everyone gives money. if a guy is starving and he needs to eat a seudah and you give him 20 bucks can he eat it. no hes still hungry. if anyone has a good explanation please let me know. the gemara also says the mari sent back to rava through abaye pepper and ginger, since when can you give spices for shaloch manos? another unanswered question.
efsher someone can give some terutzim lechora.
