Are the rabbis trying to make us sick?

Here’s a link showing the amount of matzah, wine, and maror that one is required to eat at a seder, according to some traditional rabbinic opinions.  The amounts are roughly almost three sheets of machine-made matzah or about one and two-thirds sheets of hand-made matzah, wine equaling the approximate equivalent of one and a half cans of soda pop, and, for us masochistic Ashkenazim, about a shot-glass worth of ground horseradish.  And all of those are supposed to be eaten or drunk within a prescribed amount of time, usually only a few minutes, if I understand correctly.  This is how the rabbis show concern for our health?

Then there’s the matter of kitniyot (again, for us crazy Ashkenazim).  There’s some controversy regarding whether the South American grain quinoa is or is not kitniyot.  Those of us who have health problems that limit how much matzah we can eat and/or what kind of matzah we can eat and/or whether we can eat any kind of matzah at all, need alternatives, all the more so if we also have problems eating potatoes.  So why is it that the rabbis are so obsessed with eliminating one of the few alternatives to matzah that are permissible on Pesach?  Do the rabbis consider it irrelevant to ensure that people with dietary limitations have “starches” that we can eat on Pesach without risking our health?  😡
