Including red raspberries in the diet can help people with pre-diabetes

A study released today from the Illinois Institute of Technology shows the benefits of including red raspberries in the diet of individuals with pre-diabetes and insulin resistance

The study, published in obesity, investigated the effects of red raspberries in a group of people at-risk for diabetes who were overweight or obese and presented with prediabetes and insulin resistance. A metabolically healthy control group was also included in the study for reference.

Using a randomised, controlled, acute study design, 32 adults between the ages of 20-60 years had their blood tested over a 24-hour period after eating breakfast on three separate days.

The three breakfast meals were similar in calories and macronutrients, but differed in the amount of frozen red raspberries – one meal contained no raspberries, one contained one cup of raspberries and one contained two cups of raspberries.

The results showed that as the amount of raspberry intake increased, individuals at risk for diabetes needed less insulin to manage their blood glucose.

When two cups of red raspberries were included in the meal, glucose concentrations were lower compared to the meal with no red raspberries. The data suggest that simple inclusion of certain fruits, such as red raspberries with meals, can have glucose lowering benefits with indications of improvements in insulin responses.

These effects are particularly important for people who are overweight or obese with pre-diabetes.

“People at risk for diabetes are often told to not eat fruit because of their sugar content. However, certain fruits – such as red raspberries – not only provide essential micronutrients, but also components such as anthocyanins, which give them their red colour, ellagitannins and fibres that have anti-diabetic actions,” said Britt Burton-Freeman, Ph.D., director, Center for Nutrition Research at Illinois Tech.

He added, “For people who are at risk for diabetes, cardiovascular disease and other health risks, knowing what foods have protective benefits and working them into your diet now can be an important strategy for slowing or reversing progression to disease.”
