Dear Plutarch: It is very true that many people eat far more meat than is desirable.
Unfortunately there are some vegetarians who pay a high price for going to extremes.
About a year ago, in DISCOVER magazine there was an article about a man my age
who was jogging five miles a day, until he developed brain damage from eating no
meat whatsoever. Quite recently there was an item in the news of two children being
born with brain damage because their mothers ate no meat. Moderation in all things
is wise.
