The research was published in the prestigious Journal of Agriculture Food Chemistry.
Aviram and his team, including Dr. Hamutal Borochov-Neori of Southern Arava Research and Development, have been studying the health benefits of dates for some time.
The most effective varieties are the yellow Barhi, Deri, Medjool and Halawi. The other date varieties are Amari, Deglet, Noor, Hadrawi and Hayani.
There are about 20 date varieties growing in various parts of the world, including North Africa and Arizona in the US, but the Israeli varieties growing in the Jordan Valley and the Arava (and in Jericho in the Palestinian Authority) are the best, said Aviram.
Aviram told The Jerusalem Post on Sunday that it doesn’t matter if dates are eaten fresh or dried, but consuming silan – date syrup – can offer little improvement to healthy cardiovascular systems.
