They call it a “meat eater”. Outside of Polar Bears, most bears that I am familiar with are quite omnivorous, and enjoy their huckleberries and honey greatly.
But I think this stuff generally falls into the area of "unsubstantiated guesswork".

Wednesday, July 23, 2008MOSCOW, Russia -- A pack of enormous bears searching for food killed and ate two men at mines in Russia's Pacific Kamchatka region and have kept hundreds of geologists and miners from reaching the mine, news agencies reported Wednesday.
A pack of up to 30 Kamchatka bears -- which are similar to grizzlies -- prowled around two mines of a local platinum mining company where they killed the two guards on Thursday, local officials were quoted by the Russian ITAR-Tass news agency as saying.
About 400 company workers have refused to return to the mines for fear of the bears, which stand 10 feet (three meters) tall on their hind legs and weigh up to 1,500 pounds (700 kilograms), Interfax reported.

These bears were different. I believe they concluded they must have been mainly meat eaters, becasue they couldn’t sustain that size in that ecosystem without eating a lot of meat.
