Underscoring the risk of consuming desalinated water devoid of magnesium, BIU Prof. Yona Amitai, a public health expert, recommends adding the mineral to drinking water in order to thwart fatal heart disease.
That, in fact, is the conclusion of a joint Israeli study conducted by researchers from BIU and Sheba Medical Center (Tel Hashomer). “In recent years, as desalinated water has begun to be widely used, there has been a higher death rate in hospitals in desalinated-water areas than in those in other regions,” explains Prof. Yona Amitai of the BIU Dept of Management, noting that no significant difference between death rates in these hospitals existed prior to the use of desalinated water. The study is a part of a PhD thesis by Meital Shlezinger.
For Israel, a global leader in the desalination of seawater (DSW) that news is the cause for some genuine concern. DSW accounts for about 70% of the drinking water consumption among Israelis. That means that a significant swath of the local population is drinking tap water with very low magnesium (Mg) content, which can cause adverse health effects, and even increase risk for heart diseases and risk for death.
Presenting at the recent Environment and Health Fund Conference in Tel Aviv, Amitai delineated the importance of magnesium to human health and the implications for sea water desalination.
Notwithstanding the high costs and the possible corrosion of water pipelines, Amitai believes that the benefits (including increased Mg content in produce and improved crop production) outweigh the disadvantages. “Given the increased use of DSW in Israel and the detrimental health effects from low water Mg content (i.e. death toll of over 500 people per year), the decision on adding Mg should not be delayed.”
Postscript: Following the Israeli media’s report on the BIU research, Prime Minister Benjamin Netanyahu recently directed the Health Ministry to proceed with the pilot plan to add magnesium to desalinated water.
