Only 5 per cent of your daily calorie intake should be from sugar, agency says
Just try sugar-coating this: The World Health Organisation says your daily sugar intake should be just 5 per cent of your total calories - half of what the agency previously recommended, according to new draft guidelines published yesterday (March 5).
After a review of about 9,000 studies, WHO’s expert panel says dropping sugar intake to that level will combat obesity and cavities. That includes sugars added to foods and those present in honey, syrups and fruit juices, but not those occurring naturally in fruits.
Dr Francesco Branca, WHO’s director for nutrition, conceded the new target was somewhat aspirational.
Eating too much meat and eggs is ‘just as bad as smoking’, claim scientists
A new study by Ben Marzeion from the University of Innsbruck and Anders Levermann from the Potsdam Institute for Climate Impact Research said that from the Statue of Liberty in New York to the Tower of London and the Sydney Opera House -- sea-level rise will not only affect settlement areas but also numerous world heritage sites listed by Unesco.
Nearly one-fifth of world cultural heritage sites would be affected by global warming of a further three degrees Celsius, they said.
If global average temperature increases by just one degree Celsius more than 40 of these sites will be threatened by the water during the next 2000 years.
With a temperature increase of three degrees, about one fifth of the cultural world heritage will be affected in the long term.
Among the world heritage sites affected are the historical city centres of Bruges, Naples, Istanbul and St Petersburg and a number of sites in India and China.
"If large ice masses are melting and the water is disper .. throughout the oceans, this will also influence the Earth's gravitational field," Levermann said.
"Sea-level rise will therefore vary between regions," he added.
They calculated future sea-level rise for all world regions and compared these projections with today's coastal settlement areas and the sites of the cultural world heritage. "Our analysis shows how serious the long-term impacts for our cultural heritage will be if climate change is not mitigated," Levermann said.
"The global average temperature has already increased by 0.8 degrees compared to pre-industrial levels. If our greenhouse-gas emissions increase as they have done in the past, physical models project a global warming of up to five degrees by the end of this century".
The physical processes behind the global rise of the oceans are gradual, but they will continue for a very long time," says climate scientist Ben Marzeion.
"This will also impact the cultural world heritage".
Angry people 'risking heart attacks'
Five episodes of anger a day would result in around 158 extra heart attacks per 10,000 people with a low cardiovascular risk per year, increasing to about 657 extra heart attacks per 10,000 among those with a high cardiovascular risk.
The Harvard School of Public Health researchers say the risk with a single outburst of anger is relatively low - one extra heart attack per 10,000 people per year could be expected among people with low cardiovascular risk who were angry only once a month, increasing to an extra four per 10,000 people with a high cardiovascular risk.
They identified a dangerous period of about two hours following an outburst when people were at heightened risk.
The meta-analysis found in the two hours immediately after feeling angry, a person's risk of a heart attack increased nearly five-fold (4.74%), the risk of stroke increased more than three-fold (3.62%).
Senior Cardiac Nurse at the British Heart Foundation Doireann Maddock said, "This research found that people's risk of heart attack and stroke increased for a short time after they lost their temper. It's not clear what causes this effect. It may be linked to the physiological changes that anger causes to our bodies, but more research is needed to explore the biology behind this.''
