It‟s official... chocolate is good
for you!
Sweet news: a recent study backs up earlier findings that found a
potential positive link between chocolate and heart health.
It‘s the news that chocoholics have been waiting for - a bar of the dark
stuff is officially good for your health. It has long been believed that a
small amount of cocoa-rich dark chocolate can be beneficial because
of its high antioxidant and anti-inflammatory properties.
A major study has now suggested that eating large amounts of
chocolate could also be associated with a one-third reduction in the
risk of developing heart disease.
Dr Oscar Franco from the University of Cambridge carried out a large
scale review of the existing evidence to see the effects of eating
chocolate on heart attacks and strokes.
He analysed the results of seven studies, which had involved more
than 100 000 people with and without existing heart disease. Five
studies reported a beneficial link between higher levels of chocolate
consumption and the risk of cardiovascular events.
They found that the highest levels of chocolate consumption were
associated with a 37 per cent reduction in cardiovascular disease and
a 29 per cent reduction in stroke compared with lowest levels.
The studies did not differentiate between dark or milk chocolate and
included consumption of chocolate bars, drinks, biscuits and desserts.
But despite the findings, he said they should be taken ‗with caution‘.
This was because commercially available chocolate is high in calories
- around 500 calories for every 100 grams - and eating too much of it
could lead to weight gain and put eaters at risk of diabetes and heart
disease.
The findings were published in the British Medical Journal.
Dapper krieke sal sterf vir die liefde
Mans dapper genoeg om hul lewens vir hul bemindes af te staan kan
ook in krieke waargeneem word, het navorsers bevind.
Die navorsers het bevind krieke is nie net romanties van aard as dit
by hul musikale gekriek kom nie, maar ook in hul toegewydheid aan
die leifde.
―Baie mense dink sulke dapper gedrag vind slegs by mense of ander
soogdiere plaas,‖ het die navorser Rolando Rodrìguez-Muñoz gesê.
―Asof dit met intelligensie of opvoeding verband hou.‖
―Ons het bevind selfs klein manlike insekte, wat mens nie gewoonlik
as slim of liefdevol sal beskryf nie, kan dapper en beskermend oor hul
maats wees,‖ het Rodrìguez-Muñoz, van die Universiteit van Exeter in
Brittanje, gesê.
Die navorsers het 200 000 ure se beeldmateriaal van krieke
bestudeer en bevind by paartjies vergroot die wyfie se kanse op
oorlewing as die twee aangeval word terwyl die mannetjie s‘n
verklein.
―Krieke se verhoudings is baie anders as wat ons verwag het,‖ het
Rodríguez-Muñoz gesê. ―Hulle boelie glad nie hul maats nie.‖
―Inteendeel, mannetjies is baie dapper en beskerm die wyfies.‖
Die navorsing is in die joernaal Current Biology gepubliseer.
Mans met diep stemme laat vroue
luister
Mans wat woordjies van liefde in hul beminde se ore wil fluister,
moet dit in ‗n diep stem doen as hulle wil hê die meisie moet hulle
onthou.
Navorsers het gesê ‗n nuwe studie oor vroue se voorkeure van
mansstemme dui aan die mens se geheue is ingestel op dinge wat
ons voortbestaan sal verseker.
Die navorsers van die Universiteit van Aberdeen in Skotland en die
McMaster-universiteit in Kanada het vroue prente van voorwerpe
gewys terwyl óf ‗n diep stem óf ‗n stem met ‗n hoë toonhoogte die
naam van die voorwerp uitspreek.
Daarna is die vroue prente van twee soortgelyke, maar nie
identiese, voorwerpe gewys en gevra watter een hul vroeër gewys
het.
Die meeste vroue het die voorwerpe onthou wat deur die diep stem
begelei is.
―Dit help vroue om ‗n maat te kies,‖ het die navorser Kevin Allan
gesê. "Dit is uiter belangrik, want ‗n swak keuse kan slegte gevolge
vir die mens se voortbestaan inhou."
Wetenskaplikes het reeds geweet mans se stemme is belangrik vir
potensiële maats om te onderskei of mans geneties sterk is en of
hulle dalk emosioneel koud is.
"The most important thing that a father can do
for his children is to love their mother."
