Rose hip lowers cholesterol and blood pressure in obese individuals

This study investigated whether daily intake of 40 g rose hip powder over 6 weeks exerts beneficial metabolic effects in obese individuals. A total of 31 obese individuals with normal or impaired glucose tolerance were enrolled in a randomized, double-blind, cross-over study in which metabolic effects of daily intake of a rose hip powder drink over 6 weeks was compared with a control drink. The results showed that in comparison with the control drink, 6 weeks of daily consumption of the rose hip drink resulted in a significant reduction of systolic blood pressure (-3.4%), total plasma cholesterol (-4.9%), low-density lipoprotein (LDL) cholesterol (-6.0%) and LDL/HDL ratio (-6.5%). The Reynolds risk assessment score for cardiovascular disease was decreased in the rose hip group compared with the control group (-17%). The authors conclude "Daily consumption of 40 g of rose hip powder for 6 weeks can significantly reduce cardiovascular risk in obese people through lowering of systolic blood pressure and plasma cholesterol levels".
