Reduced fat intake may cut diabetes risk without weight loss - FYI

[Guest guest]

Reducing the proportion of fat in the diet could significantly reduce the

risk of developing type-2 diabetes, even without weight loss, according to a

new study.

The research, published in the *American Journal of Clinical Nutrition*,

challenges the idea that weight loss is necessarily a crucial factor for

reducing risk of type-2

The researchers, from the University of Alabama at Birmingham (UAB) provided

69 healthy overweight individuals with one of two calorically identical

diets for eight weeks - either a reduced carbohydrate, higher fat diet (43

percent carbohydrate, 39 percent fat), or a standard diet of 55 percent

carbohydrate and 27 percent fat.

They found that after eight weeks, the group on the lower

fat<http://www.foodnavigator-usa.com/content/search?SearchText=lower+fat & FromNew\

s>diet

had significantly higher insulin secretion and better glucose

tolerance

and tended to have higher insulin sensitivity.

* " These improvements indicate a decreased risk for diabetes, " * said UAB

department of nutrition professor and lead author of the study Barbara

Gower.

*Quality not quantity*

The researchers took into account any minor fluctuations in weight during

the study, and provided participants with the amount of food necessary to

maintain weight, they said.

Gower said: * " People find it hard to lose weight. What is important about

our study is that the results suggest that attention to diet quality, not

quantity, can make a difference in risk for type 2 diabetes. " *

The proportion of the population diagnosed as diabetic has been rising

rapidly in recent years. According to the International Diabetes Federation,

8.5 percent of the European population now has diabetes, and that figure is

expected to rise to 10 percent by 2030. In North America and the Caribbean,

the figure is even higher - 11.7 percent of the population in the region is

diabetic, expected to rise to 13.6 percent by 2030.

*Particular significance for blacks*

The risk of developing type-2 diabetes is higher for black people, and this

latest research found that results for African-American study participants

on the lower fat diet were more significant that for European-Americans.

Gower said that a stronger difference in insulin secretion for blacks on the

lower fat diet, compared to the lower carb group, could indicate that diet

composition is an important factor for mitigating diabetes risk in this

population in particular.

Study co-author and UAB dietician Lee Goree said that the 39 percent

fat or 27 percent fat proportions of the diets used in the study* " were

actually fairly moderate. " *

Current dietary advice in the US recommends an ideal proportion of fat

intake to be 20 to 35 percent of daily calories, with less than 7 percent of

total calories from saturated fat.

* " Individuals at risk for diabetes easily could adopt the lower fat diet we

employed, " * said Goree. * " Our findings indicate that the lower-fat diet

might reduce the risk of diabetes or slow the progression of the disease. " *
