Beckham booed by fans

It is among the greatest health debates of our time; splashed across newspapers with contradicting headlines - is coffee good for you or not?

Depending on what you read, it is either a cancer-causing, sleep-depriving, stomach ulcer-inducing black death or the secret to long life, cutting the chance of stroke, diabetes and cancer.

The latest research - a study of 8,412 people across the UK who each underwent an MRI heart scan - is intended to put to bed (caffeine allowing) conflicting reports of the pros and cons of consumption.

The study, funded by the British Heart Foundation, contradicted previous findings that it stiffens arteries, putting pressure on the heart and increasing the likelihood of a heart attack or stroke, leading to warnings to cut down.

Numerous studies have recognised the benefits of coffee in cutting oral and esophageal cancer, the risk of a stroke and cirrhosis of the liver. 

The benefits are often linked to biologically active compounds including caffeine, flavonoids, lignans, and other polyphenols, which benefit the body. These and othetr coffee compounds regulate genes involved in DNA repair, have anti-inflammatory properties and are associated with lower risk of insulin resistance, which is linked to type-2 diabetes.

But as doctors warn, too much of anything is inadvisable. The British Heart Foundation found the heaviest coffee drinkers in the study were most likely to be men who smoked and drank alcohol regularly.

Excessive amounts of coffee also unsettle the stomach causing or contributing to stomach ulcers. It also stains the teeth over time, hampers absorption of minerals and vitamins like zinc and iron.

It also raises blood pressure, which is largely problematic for people with existing conditions.

So the heaviest drinkers of the black stuff - some in the study had up to 25 cups per day - may want to rein it in.

Torno Subito by Massimo Bottura

When the W Dubai – The Palm hotel opens at the end of this year, one of the highlights will be Massimo Bottura’s new restaurant, Torno Subito, which promises “to take guests on a journey back to 1960s Italy”. It is the three Michelinstarred chef’s first venture in Dubai and should be every bit as ambitious as you would expect from the man whose restaurant in Italy, Osteria Francescana, was crowned number one in this year’s list of the World’s 50 Best Restaurants.

Akira Back Dubai

Another exciting opening at the W Dubai – The Palm hotel is South Korean chef Akira Back’s new restaurant, which will continue to showcase some of the finest Asian food in the world. Back, whose Seoul restaurant, Dosa, won a Michelin star last year, describes his menu as,  “an innovative Japanese cuisine prepared with a Korean accent”.

Dinner by Heston Blumenthal

The highly experimental chef, whose dishes are as much about spectacle as taste, opens his first restaurant in Dubai next year. Housed at The Royal Atlantis Resort & Residences, Dinner by Heston Blumenthal will feature contemporary twists on recipes that date back to the 1300s, including goats’ milk cheesecake. Always remember with a Blumenthal dish: nothing is quite as it seems.

Hydrogen has an estimated $11 trillion market potential, according to Bank of America Securities and is expected to generate $2.5tn in direct revenues and $11tn of indirect infrastructure by 2050 as its production increases six-fold.

"We believe we are reaching the point of harnessing the element that comprises 90 per cent of the universe, effectively and economically,” the bank said in a recent report.

Falling costs of renewable energy and electrolysers used in green hydrogen production is one of the main catalysts for the increasingly bullish sentiment over the element.

The cost of electrolysers used in green hydrogen production has halved over the last five years and will fall to 60 to 90 per cent by the end of the decade, acceding to Haim Israel, equity strategist at Merrill Lynch. A global focus on decarbonisation and sustainability is also a big driver in its development.
