I saw a show on TV about the fattest people on earth--the people of the island nation of Tonga in the South Pacific. They used to eat what they could catch in the sea, the taro root they could grow and the coconuts they would shimmy up the palms to harvest. Now the inhabitants look like brown Michelen men (and women.)
WWII came along and the natives got a taste of Spam, which has become is their favorite meat, loaded as it is with fat and salt. Also a big favorite is corned beef. A shot inside a grocery store showed giant cans that looked to be about 5lb. size, of corned beef that are sent especially to Tonga with a much higher fat content than what Americans are used to. Diabetes and high blood pressure are rampant. This nation of really obese people are eating themselves literally to death.
Since everything has to be brought to Tonga in ships, if their food supply were ever cut off, they would eventually starve to death. Never worry--send them to Mississippi, home of the fattest folks in the US, and they will fit right in.
