STUDY: People Who Eat High Fiber Diets Live Longer, Or Vice Versa

This is one of those "associations" in science where you can't tell cause and effect.

Here's a quotation from the media's article on the research that appeared in the Archives of Internal Medicine."  (Miami Herald Health, Feb 22)
Researchers used data from the National Institutes of Health-AARP Diet and Health study that asked people ages 50 to 71 what they ate for the last year and how often they ate it. Researchers followed the participants for an average nine years, in which time 20,126 and 11,330 women died.  Those who consumed diets higher in fiber had a lower risk of death. The 20 percent of men and women who ate the most fiber (29.4 grams per day for men and 25.8 grams for women) had a 22 percent lower risk of dying compared with those who ate the least amount (12.6 grams per day for men and 10.8 for women).
The title of the news article was "Study links high-fiber diet to longer life."  Parse the words carefully...the media was careful not to explicitly state that eating high fiber will tend to make you live longer.  They just said there's a "link."
The link could be that healthier people who would naturally live longer happen to eat more fiber.
So, where's the beef?
