Animal
Fat Intake Associated With Diabetes Risk
Consumption
of animal fat and not carbohydrates appears to be linked to the
development of diabetes.
That,
according to findings published in the February issue of Diabetes.
Dr.
Basil G. Karamanos, of Athens University, Greece, and colleagues
examined the effect of dietary factors on the development of type 2
diabetes. Included in the study were 204 subjects with recently
diagnosed diabetes (RDM), 42 with undiagnosed diabetes (UDM), and 55
with impaired fasting glucose (IFG).
The
researchers compared each group of subjects with a matched control
group of nondiabetics. Nutritional habits were assessed for all
groups. In the RDM group, nutritional habits before diabetes diagnosis
were evaluated.
Forty-nine
percent of patients in the RDM group had a family history of diabetes,
compared with 14.2% of controls (p < 0.001). RDM patients exercised
and more often had sedentary professions. Carbohydrate contribution to
the energy intake was lower in RDM patients (53.5%) than controls
(55.1%; p < 0.05). Conversely, total fat (30.2% versus 27.8%; p
< 0.001) and animal fat (12.2% versus 10.8%; p < 0.01)
contributed more to energy intake.
Similarly,
those with undiagnosed diabetes more frequently had a family history
of diabetes than controls (38.1% versus 19.0%; p < 0.01), and more
often had sedentary professions. Carbohydrate contribution was also
lower among UDM patients (47.6% versus 52.8%; p < 0.005), while
total fat (34.7% versus 30.4%; p < 0.05) and animal fat (14.2%
versus 10.6%; p < 0.05) contributed more to energy intake.
"IGF
differed only in the prevalence of family history of diabetes (32.7%
versus 16.4%; p < 0.05)," Dr. Karamanos and colleagues report.
Thus,
they conclude that "increased animal fat in the diet may
contribute to increased incidence of diabetes." Diabetes

===============================
FACT:
In
1999, approximately 450,000 deaths occurred among people with diabetes
aged 25 years and older. This figure represents about 19% of all
deaths in the United States in people aged 25 years and older. CDC
