Do Chinese people not use "和"? I'm currently taking a Chinese class with native speakers, and one criticism I've gotten a lot on my writing is that I use “和” way too much. I understand that Americans say "and" more than would be culturally appropriate in China, but my teacher has recommended I take out all ands, including in lists (eg. 这家餐馆有水饺、米饭，和面条 --> 这家有餐馆水饺、米饭、面条。). It sounds strange to me not to use "and" at al, but again, not a native speaker. Should I just use something like 而且 instead and avoid 和，or just try as hard as I can never to use "and", even in lists? Or do Chinese people use "和“ more than my teacher seems to indicate? Also, is there a difference between writing and speaking in the matter?

EDIT: feel free to add a Chinese translation! I wasn't sure on quite a few words and phrases and figured it'd be better to call in some outside help on this one.
和 comes from old verb "to mix two things into one". From "to mix" 和 developed meaning "with" and "and". But the old meaning still lingers there, that's why 和 can't be used in some situations.


  老板喜欢咖啡和茶。


works like charm cause you literally can "mix" coffe and tee.


  今天和明天都可以吗？


the same here.
but 


  *我去了超市和买了水果


-- not good. WHat are you "mixing"? "market" and "buying"? Noun and verb? 

about而且:


且 means 'further'. It was used as a future tense marker in old Chinese, just like 'will' is used in English.
而 is a subordinate conjunction. That is, it serves functions of 'but, and, where, who, when ect.' thus subordinating one sentence clause to the other. But how one should translate 而 is unknown (to me at least), it's quite volatile in it's meaning.
而且 means "further than this", 'but more' or 'even more'. 


So 而且(even more) and 和 (to mix) are quite different in their meaning.
