Basikhohlisa ngesidingo sokusela iiglasi ezisibhozo zamanzi kunye nesi sixa esicetyiswayo sokusela

"ayixhaswanga ngokwesayensi"

UYosuke Yamada weZiko leSizwe uthe ukusungula izinto ezintsha I-Biomedical, Health and Nutrition eJapan, kunye nomnye wababhali bokuqala bolu phando lokuba "ingcebiso yangoku (o.k.k. ukusela iikomityi ezisi-8) ayixhaswanga ngokwesayensi konke konke," wongezelela ngelithi "izazinzulu ezininzi aziqinisekanga ngomthombo wesi sincomo. .”

Enye yeengxaki, ngokutsho kwephephandaba laseBritani, kukuba uqikelelo lwangaphambili lweentswelo zabantu zamanzi luyayibetha ngoyaba into yokuba ukutya kwethu kunamanzi, nto leyo enokuba negalelo kumlinganiselo omkhulu wokusetyenziswa kwethu xa kukonke.

Imozulu eshushu nefumileyo

Ukongezelela, uphando, olupapashwe kwiphephancwadi iSayensi, luvavanye ukusela kwamanzi abantu be-5 phakathi kweminyaka eyi-604 kunye ne-8 iminyaka evela kumazwe angama-96.

Kodwa olu phando ludize ukuba abo bahlala kwiindawo ezishushu nezifumileyo nakwindawo eziphakamileyo kwakunye neembaleki nabasetyhini abakhulelweyo nabancancisayo kufuneka basele amanzi amaninzi.

Kwakhona ndaphawula ukuba amadoda aphakathi kweminyaka engama-20 ukuya kwengama-35 ayenomlinganiselo “wojikelezo” lwamanzi oluyi-4.2 ilitha ngosuku. Oku kwehle ngobudala ukuya kumyinge weelitha ezi-2.5 ngosuku kumadoda aneminyaka engama-XNUMX, nto leyo exhomekeke kumandla asetyenziswa ngumzimba.

Ngokubhekiselele kubafazi abaphakathi kweminyaka engama-20 kunye ne-40, izinga "lokujikeleza" kwamanzi emzimbeni laliyi-3.3 ilitha, kwaye lehla ukuya kwi-2.5 ilitha ekufikeleleni kwiminyaka engama-90 ubudala.

iyaselwa

Unjingalwazi uJohn Speakman weYunivesithi yaseAberdeen, umbhali-mbhali wophando, wathi: "Olu pho nonongo lubonisa ukuba isiphakamiso esiqhelekileyo sokusela iiglasi ze-8 zamanzi - okanye malunga neelitha ezimbini ngosuku - mhlawumbi liphezulu kakhulu kubantu abaninzi."

Nangona kungekho ngozi icacileyo ngokusela amanzi amaninzi, iphephandaba laseBritani lithi ukufumana amanzi acocekileyo okusela kunokubiza imali eninzi kule mihla.
