"How long does one survive without fruit and vegetables?"

Do a search about the diet of Eskimos. You will find they can live a long time without.

[Triple Word Score]

The Eskimo survived eating meat only for months at a time because they ate the ENTIRE animal, and generally uncooked. You will become malnourished if you tried to live on only the meat cuts you can get at the supermarket meat counter.

The Eskimo has not fared very well on the Western diet. When carnivores start on sugar and processed starches, their teeth deteriorate very fast. But once you have grocery stores, you use them...you don't go sit in ice water to find a seal any more often than you must.
