Grizzlies show no clinical signs
of disease following short-term consumption of saturated fats but scientists
question long-term health

Campgrounds and cottages are
getaways for humans. They are also locations where grizzly bears are acquiring
appetites for human foods that are high in saturated fats. Diets high in
saturated fats are associated with many diseases in humans. Does the health of
a bear suffer too?
A new study published today in
the Canadian Journal of Zoology found that captive bears fed a diet high in
saturated fats and low in "healthy" polyunsaturated fats did not show
symptoms of disease typically observed in humans eating foods high in saturated
fats such as insulin resistance, a precursor to type 2 diabetes.
Researchers from Washington State
University (WSU) fed adult bears one of two diets prior to hibernation, one
high in polyunsaturated fats with oats and salmon and the other high in
saturated fats containing beef and cheese. The bears fed from May to the end of
October and then hibernated over winter. In spring when they woke it was time
for a health check-up.
