A randomized controlled trial was performed in which 38 hyperlipidemic patients were separated into two groups, with one group receiving 90 g/day of black seed raisins and the other group receiving no intervention. Researchers analyzed blood pressure, lipid profile, high-sensitivity C-reactive protein (hs-CRP), malondialdehyde (MDA), and serum total antioxidant capacity (TAC). At 5 weeks, participants’ cardiovascular risk factors were examined and it was shown that the blood pressure significantly reduced for those who consumed raisins and that the TAC was significantly increased. Moreover, the serum level of MDA was lower in the raisin group compared to the control group. The other factors showed no significant changes.
In conclusion, the results suggest that consuming black seed raisins could lead to beneficial effects on some cardiovascular risk factors like blood pressure and serum antioxidant capacity in individuals with hyperlipidemia.
