Changes In Antioxidant Status, Blood Pressure, And Lymphocyte DNA Damage From Grape Juice Supplementation
Notes for this study:
||(umol/L). Mean + SEM. Placebo: before 59.07 ± 5.70, after 68.16 ± 6.70. Grape: before 63.61 ± 5.69, after 68.72 ± 5.70.
|Number of Subjects
In a randomized, double-blind, placebo-controlled trial, 40 healthy but borderline hypertensive participants were allocated to take 5.5 ml/kg of grape juice or a calorie-matched non-fruit juice daily for 8 weeks while on a diet low in fruits and vegetables.
Funding issues for this study:
Systolic and diastolic blood pressure were reduced significantly more in the grape juice group than the placebo group. There was no statistically significant difference in lipid profile, antioxidant potential, vitamin C, or catalase, while there a small reduction in DNA damage.
Funding not disclosed. Welch Foods Inc provided juice.
