Going into the most recent study, the team was aware of the individual benefits provided by pomegranates and dates. Pomegranate juice, rich in polyphenolic antioxidants (derived from plants), has been shown to most significantly reduce oxidative stress. Dates, which are rich sources of phenolic radical scavenger antioxidants, also inhibit the oxidation of LDL (the so-called “bad cholesterol”) and stimulate the removal of cholesterol from lipid-laden arterial cells. Prof. Aviram had a hunch that since dates and pomegranate juice are composed of different phenolic antioxidants, the combination could thus prove more beneficial than the sum of its parts.
In a trial performed on arterial cells in culture, as well as in atherosclerotic mice, the Technion team found that the triple combination of pomegranate juice, date fruits and date pits did indeed provide maximum protection against the development of atherosclerosis because the combination reduced oxidative stress in the arterial wall by 33% and decreased arterial cholesterol content by 28%.
The researchers conclude that people at high risk for cardiovascular diseases, as well as healthy individuals, could benefit from consuming the combination of half a glass of pomegranate juice (4 ounces), together with 3 dates. Ideally, the pits should be ground up into a paste and eaten as well, but even without the pits, the combination is better than either fruit alone.
