Comparing gallstone attack rates in omnivores versus vegetarians.
"Normal" cholesterol redefined.
The number one digestive reason people are hospitalized, though, is because of a gallbladder attack. Every year, more than a million Americans are diagnosed with gallstones, and about 700,000 have to get their gallbladders surgically removed. What are gallstones made of? In 80-90% of cases, the gallstones are made out of cholesterol. Here’s a picture of someone’s gallbladder packed with gallstones. All that yellow you see making up the stones is pure crystallized cholesterol that built up in this person’s body.
If the only source of dietary cholesterol is animal foods, one might expect meateaters to be at higher risk. Turns out you have to go all the way to Katmandu to find some good science. Non-vegetarians were found to be at higher risk for gallstones than vegetarians, but not just a little more risk. Nine times the risk. 9 to 1 odds of getting gallstones; nonvegetarians versus vegetarians.
