If eating red meat...

...is bad for you, how did my parents -- two of the world's greatest carnivores -- live so long? (My dad passed away two years ago at age 90 and my mother is still going strong at age 92.) 

The Los Angeles Times has an article, "All Red Meat is Bad For You, New Study Says," which reports (my emphasis): 

Eating red meat — any amount and any type — appears to significantly increase the risk of premature death, according to a long-range study that examined the eating habits and health of more than 110,000 adults for more than 20 years. 

For instance, adding just one 3-ounce serving of unprocessed red meat — picture a piece of steak no bigger than a deck of cards — to one's daily diet was associated with a 13% greater chance of dying during the course of the study. 

Even worse, adding an extra daily serving of processed red meat, such as a hot dog or two slices of bacon, was linked to a 20% higher risk of death during the study. 

I'm a goner.
