WeightControl.com Interview with: Britt Burton–Freeman, Ph.D Director of the Center for Nutrition Research at IFSH Associate Professor, Food Science and Nutrition Illinois Institute of Technology
WeightControl.com: What is the
background for this study? What are the main findings?
Response: Red raspberries contain appreciable amounts of dietary fiber and a
variety of other nutrients, such as vitamin C, vitamin K, magnesium and
potassium. They also contain phytochemicals, such as polyphenols with
documented biological activity suggesting metabolic benefits. However, there is
limited data assessing the potential effects of red raspberries in humans,
particularly in those people who might benefit the most, ie., people at risk
for diabetes mellitus.
We investigated the health benefits of consuming 1-2
cups of red raspberries in a group of people who were overweight/obesity and had
prediabetes and insulin resistance.
The results showed that when a breakfast meal was
consumed with raspberries, less insulin was needed to manage blood sugar
compared with a meal with no raspberries. Moreover, when two cups of red
raspberries were included in the breakfast meal, blood sugar concentrations
were significantly lower compared to consuming breakfast without raspberries.

What is the background for this study? What are the main findings?
weight loss is prescribed at the rate of 1 to 2 pounds per week. However,
this is largely based on the observation that weight losses faster than 2
pounds per week put patients at an increased risk for gallstones. It is
unclear whether this is the optimal rate of weight loss for CVD or diabetes
outcomes. Furthermore, fast weight loss has historically thought to be
associated with poorer long term weight loss. However, this was largely
based on research using liquid diets. Recent evidence suggests that
faster weight loss may be similar to slower weight loss when more sensible
lifestyle interventions are used. Thus, if there are additional benefits
of faster weight loss for CVD or diabetes outcomes, then there may a rationale
for prescribing faster weight loss as the overall rate of gallstones is fairly
observed that those who lose weight faster than 2lb/wk tend to lose more weight
overall, but for the same overall weight loss, there is no difference in terms
of health benefits with fast or slow weight loss.
