An interesting page detailing the natural carcinogens in our
thnksgiving dinners. The whole site is worth a look at.
Below is an excerpt from the holiday page:
The primary risk factor in holiday meals—other than the risk of
food poisoning from
the improper handling or preparation of
food—is getting too
much of a good thing. A hungry holiday eater
can easily consume
2,000-plus calories at one sitting. A
consistent intake of
excessive calories contributes to obesity,
with its attendant
higher risk of heart disease. Interestingly,
excessive caloric
intake has been called the "most striking"
carcinogen in rodent
carcinogenicity studies. Body weight is a
good predictor of a
rat's risk of cancer as shown in comparisons
of rats on
calorie-restricted diets and rats permitted to eat all
they want.
