Polydextrose Dietary Fiber May Reduce Calorie Intake
A recent study suggests that consuming polydextrose dietary fiber may reduce calorie consumption by up to 15%.
For their analysis, researchers from DuPont Nutrition & Health and the University of Oxford examined data from seven studies. In all of the studies, polydextrose was consumed either alone or with other foods.
The separate subjective feelings of appetite reported in the studies were Hunger, Satisfaction, Fullness, Prospective Food Consumption and the Desire to Eat.
In order to be able to make a meaningful comparison of the results obtained using widely differing criteria, the researchers developed a new methodology to estimate changes in appetite before and after a meal. They found that consuming between 6.25 and 25 grams of polydextrose dietary fiber was associated with up to a 15% reduction in calorie consumption. Hunger between meals was also reduced.
The researchers wrote that this was the first study to show that polydextrose reduces the Desire to Eat during Satiation period.
The study was published January 14, 2016, in Nutrients.
Polydextrose dietary fiber is a soluble fiber. Previous studies have linked fiber consumption with lowering total cholesterol and LDL cholesterol, and regulating blood sugar for people with diabetes.
Soluble fiber can be found naturally in oats, peas, beans, apples, citrus fruits, carrots, barley and psyllium. Insoluble fiber can be found in whole wheat and grains, brown rice, fruit, broccoli, cabbage and dark leafy vegetables.
