German researchers have found that eating fibre-enriched bread for as little as three days improved insulin sensitivity in overweight and obese women by eight percent.
The researchers from the German Institute of Human Nutrition randomized 17 overweight or obese women, with normal glucose metabolism to eat nine macronutrient-matched portions of fibre-enriched bread or control bread for a 72-hour period.
The fibre-enriched bread provided 31.2 grams of insoluble fibre per day, while the control bread was standard white bread.
Researchers found the fibre enriched bread significantly improved glucose disposal, equivalent to an eight percent improvement in insulin sensitivity.
This latest study, published in the journal Diabetes Care adds to the number of studies linking whole grains to lower risks of disease. Good sources of insoluble fibre include wheat bran, whole grains, nuts, seeds, and many fruits and vegetables.
