To study the effect of rose hip powder on type 2 diabetes and heart disease risk, researchers randomly gave 31 obese people with normal or impaired glucose tolerance a drink that contained 40 grams of rose hip powder, or a control drink, containing no rose hips. The beverages, which were consumed daily for six weeks, looked and tasted similar; the study participants and researchers did not know who was taking rose hips and who was not.
After six weeks, the subjects consumed no drinks for a two-week washout period, and then the groups were switched. As with the first study phase, the participants and researchers did not know who was taking rose hips. In comparison with the control drink, six weeks of daily consumption of the rose hip drink resulted in a significant reductions of:
There were no differences in body weight, diastolic blood pressure (the bottom number), glucose tolerance, HDL cholesterol, triglycerides, and markers of inflammation between the two groups in either study phase.
According to the study authors, these study findings indicate that rose hip powder “may represent an attractive alternative to statin treatment for people that, because of muscle pain and increases in liver and muscle enzymes, do not tolerate statins.”
This study found that a daily rose hip powder supplement may reduce heart disease risk in obese people by lowering systolic blood pressure and cholesterol levels. If you are interested in trying rose hips to lower your heart disease risk, keep the following in mind:
