Researchers uncover varying links between added sugar sources—like sweetened drinks, treats, and toppings—and risks for conditions such as heart failure, stroke, and aneurysms.

Cardiovascular disease (CVD) is a leading cause of disease and death in Europe. Multiple studies support the association between CVD and unhealthy dietary habits; however, the impact of added sugar and different types of CVD remains unclear.

A recent study published in Frontiers in Public Health examines the risk of seven different types of CVDs associated with added and free sugar in foods and beverages. The regulation of sugar intake

The incorporation of sugar into food products can cause consumers to overeat high-calorie, nutrient-empty foods at the cost of nutritious foods. Furthermore, added sugar increases the risk of tooth decay and weight gain.

Nordic guidelines recommend that less than 10% of total energy intake is provided by added and free sugar, including sugars naturally occurring in fruit juice concentrates, fruit juices, honey, and syrups. Likewise, both the American and World Health Organizations recommend less than 10% added and free sugar intake, respectively.

The European Food Safety Authority (EFSA) points to evidence that the risk of cardiometabolic disease rises with increased consumption of sugar-sweetened beverages (SSBs). Moderately strong evidence for obesity and high blood cholesterol levels with increased added and free sugar intake has also been reported.

Despite these observations, it remains unclear whether added and free sugar intake is directly associated with an increased risk of CVD. Moreover, the association with overall CVD risk does not correlate with the risk for individual cardiovascular conditions due to contradictory findings. Most studies that have examined this association have relied on a single measurement of added sugar consumption for their analyses and lack long-term follow-up data. About the study

The current study examines how the consumption of added sugar, sugar-sweetened foods (SSFs), and SSBs is associated with the risk of ischemic stroke (IS), hemorrhagic stroke (HS), myocardial infarction (MI), heart failure (HF), aortic stenosis (AS), atrial fibrillation (AF), and abdominal aortic aneurysm (AAA).

The study included 69,705 individuals in two Swedish cohorts. Data on added sugar intake (ASI) were collected in 1997 and 2009 in over 60% of study participants. The average body mass index (BMI) was 25.3 kg/m2, with a mean age of 59.9 years.

SSFs were classified as treats such as pastries, ice cream, and chocolates or toppings like marmalades, jams, sugar, and honey. SSBs included sweetened sodas and fruit drinks, excluding pure fruit juices.

The mean ASI was 9.1% of energy intake (E%) in 1997. Being male, doing more exercise, and having less education were associated with greater ASI, along with older age and higher energy intake. Low-to-moderate added sugar intake

After compensating for the effects of age, sex, and energy intake, ASI was associated with all seven CVDs; however, these associations were weakened after adjusting for lifestyle factors, BMI, and diet.

The highest category of ASI, over 20 E%, was associated with a 31% increased risk of AAA compared to the lowest intake category of five E% or less. At over 15-20 E%, the risk of IS was 9% higher.

For most outcomes, the lowest ASI was associated with the highest risk. The risk for most CVDs was lowest at 5-7.5 E%. Thus, MI, AF, IS, HF, and AS risks were reduced by 5-9% in this category compared to the lowest intake.

With ASI exceeding 7.5-10 E%, the risk of HF and AF was reduced by 6% and 4%, respectively. At over 10-15 E%, the risk of HF, AF, and AS decreased by 5%, 4% and 17% respectively. Higher ASI was associated with a greater AAA and IS risk among obese individuals, whereas higher HF risk was observed in normal-weight individuals. SSB intake

SSB intake was linearly associated with the risk of IS, HF, AF, and AAA. Consuming over eight SSB servings each week increased AF, IS, HF, and AAA risk by 11%, 18%, 19%, and 31%, respectively.

Analysis of the 2009 survey indicated an increased risk of IS and HF with greater artificially sweetened beverage consumption but not SSBs. This could be due to the small sample size for sweetened beverages, as current literature indicates a positive correlation of SSBs with increased CVD risk. SSF consumption

The lowest CVD risk was observed in the highest treat intake category, whereas the highest risk was observed among those who consumed two or fewer treats each week.

Although the mechanism remains unclear, this association might be due to better social health. In Sweden, coffee and pastries are part of fika, customary social gatherings, and may not indicate an overall unhealthy lifestyle.

Topping intake showed a mixed pattern, as those who consumed toppings had a 10% reduced risk of HF as compared to the lowest intake category. AS risk was reduced by 14-20% with increasing ASI, whereas AAA risk increased by 34%. Conclusions

The study findings do not support lowering the recommendations for added sugar intake to below five E%.”

A low to moderate intake of added sugar is associated with lower CVD risk at 5-7.5 E% as compared to either over five E% or 10 E%. Both the sugar source and the studied clinical outcome affect the nature and direction of the association.

Future studies are needed to elucidate the mechanisms involved in these associations and the role of body weight. Furthermore, confounding factors like sodium intake, an independent CVD risk predictor, should also be considered. Journal reference: Janzi, S., Gonzalez-Padilla, E., Ramne, S., et al. (2024).

Pope Francis has ‘initial, mild’ kidney problem and still in critical condition, says Vatican

Pope Francis has 'initial, mild' kidney problem and still in critical condition, says Vatican

The Pope remains in a critical condition and is now showing an “initial, mild” kidney problem – but is “vigilant” and took part in Mass in hospital with those caring for him.

The Vatican statement said Francis hadn’t had any more “respiratory crises” since Saturday evening.

However, a problem with his kidneys has emerged, with blood tests showing “an initial, mild, renal insufficiency, which is currently under control”, according to the update.

The 88-year-old Pope is still having “high-flow oxygen therapy” into his nose, while his hemoglobin value has increased after being given blood transfusions on Saturday.

The Pope has been at Rome’s Gemelli hospital since 14 February and is being treated for double pneumonia and chronic bronchitis.

Sunday evening’s statement said he was “vigilant and well oriented”, but due to the complexity of his case the prognosis is “reserved”.

“During the morning, in the apartment set up on the 10th floor, he participated in the Holy Mass, together with those who are taking care of him during these days of hospitalization,” the update added.

On Sunday morning, the Vatican said the Pope had a “tranquil” night and confirmed he would not lead prayers for the second week running.

Instead, Francis, who has been Pope since 2013, prepared words to be read on his behalf at the recitation of the Angelus.

‘I ask you to pray for me’

The Pope’s message said: “I am confidently continuing my hospitalisation at the Gemelli Hospital, carrying on with the necessary treatment; and rest is also part of the therapy!

“I sincerely thank the doctors and health workers of this hospital for the attention they are showing me and the dedication with which they carry out their service among the sick.

“In recent days I have received many messages of affection, and I have been particularly struck by the letters and drawings from children.

“Thank you for this closeness, and for the prayers of comfort I have received from all over the world! I entrust you all to the intercession of Mary, and I ask you to pray for me.”

The message is understood to have been written in the last few days.

‘The Pope is like family to us’

On Saturday night, the Vatican said the Pope was in a critical condition after a “prolonged respiratory crisis” that required a high flow of oxygen.

It said he’d had blood transfusions after tests revealed thrombocytopenia, which is associated with anaemia.

Millions around the world have been concerned about his increasingly frail health – and his condition has given rise to speculation over a possible resignation.

Faith is never lost but it feels optimism is fading

By Lisa Holland, Sky correspondent in Vatican City

It’s hard to imagine a Sunday in the Vatican City without the Pope. Every week – unless he’s travelling – he is a constant, appearing at the same Vatican windows to deliver his message.

Instead, his written words were distributed by Vatican officials. In his message, the Pope thanked his doctors and people around the world for their good wishes.

But it seems the upbeat message was written before the dramatic downturn in the Pope’s health, which has left him in a critical condition. The business and the events of the Church are continuing in his absence.

Faith is never lost but it feels like optimism is fading and we are living through the last days of Pope Francis.

In St Peter’s Square the sun shone – and a gentle light fell on the ancient stone of the basilica.
The beauty and pageantry of columns of deacons and visitors filing in for a special mass as part of the Catholic Church’s jubilee year sat awkwardly with the prognosis of the Pope’s ailing health.

The visitors and deacons who’d come from around the world to take part, and hoped to see the Pope, were left disappointed. Though they said they felt his presence. “It is what it is,” said one.

They know the Pope is an 88-year-old man who has spent the last few years assisted by a wheelchair and walking stick. Throughout his life he has been dogged by lung issues.

It leaves an almost philosophical mood ahead of what the coming days may bring.

Doctors said on Friday that he was “not out of danger” and was expected to remain in hospital for at least another week.

They also warned that while he did not have sepsis, there was always a risk the infection could spread in his body.

Sepsis is a complication of an infection that can lead to organ failure and death.

Pope Francis has a history of respiratory illness, having lost part of one of his lungs to pleurisy as a young man. He also had an acute case of pneumonia in 2023.

Volvo Penta set to show off its new BESS subsystem at bauma 2025

Volvo Penta will debut its latest modular and scalable battery energy storage system (BESS) platform for the off-grid construction and mining industries at the bauma equipment show – here’s what you can expect.

Best-known for its marine engines and gensets, Volvo Penta is the power production arm of the Volvo Group, specializing in putting energy to work. Operating under the tagline, ‘Made to Move You’, Volvo Penta is headed to bauma 2025 with a plan to keep construction, port shipping, and mining operations moving productively and competitively throughout their transitions to battery and (in theory, at least) hydrogen power.

To that end, the company will show off a job site ready version of the scalable and modular BESS subsystem concept shown last year.

Volvo says its new, modular BESS subsystem will enable other OEMs and third party system integrators to seamlessly deploy electric power to meet the ever-exceeding energy needs in construction and mining.

“Our modular and scalable battery-electric platform is designed to support the electrification ecosystem—combining high-performance drivelines with the crucial energy storage subsystems for efficient charging and operation in construction and mining,” says Hannes Norrgren, President of Volvo Penta Industrial. “We want to meaningfully collaborate with our customers on value-added customization that will enable them to stay productive, efficient, and future-ready.”

The Penta substation at bauma will be built around the company’s “Cube” battery pack, an energy-dense solution with a favorable C-rate designed to make it easy for BESS manufacturers to offer more compact job site solutions capable of charging and discharging energy with high levels of speed and efficiency, enabling both stationary and mobile BESS configurations that can change and grow to meet the evolving needs of a given asset fleet or project.

A Volvo Penta-developed DC/DC unit converts the voltage from the Cube battery packs (600 V) into lower voltage (24 V) for powering auxiliaries and portable offices.

Electrek’s Take

Volvo Penta has always provided power. Historically that’s been from combustion, but the company is looking ahead, developing products that will bring energy to job sites, tractors, and more long after the last ICE engine shuts down.

Exit poll may appear decisive – but path to coalition is not clear yet

Exit poll may appear decisive - but path to coalition is not clear yet

Initial exit polls appear to confirm what we have known for weeks: that the conservative Christian Democrats (CDU) and their Bavarian sister party the Christian Social Union (CSU) have got the most votes in the federal election, with Friedrich Merz most likely to be the next chancellor.

While this result isn’t a surprise, it doesn’t mean the path to power will be easy.

First off, the CDU-CSU don’t have a majority so they need to try to build a coalition.

Their most obvious choices as partners are the third-place Social Democrats. A two-party coalition is preferred as it can avoid excess bickering but the SPD and CDU disagree on several key points including sending long-range Taurus cruise missiles to Ukraine.

Forming a government can take months but Mr Merz is keen to speed up the process – aware of the pressing issues both at home and abroad.

One of those is the rise of the far right, with the Alternative for Germany (AfD) party celebrating historic results.

The initial results suggest that for the first time since the Second World War, a far-right party has got the second highest number of votes.

That could also cause serious issues for the next government.

As a result of Germany‘s Nazi history, mainstream parties have a long-running pact known as the “firewall” which says they will not work with the far right.

Even before the polls had closed, AfD leader Alice Weidel echoed Donald Trump and released a video statement urging people to “observe” the ballots being counted and to “protect democracy”.

How will Germany election impact Europe?

Many of the AfD’s supporters have said not allowing the second most popular party into government is undemocratic, threatening to take to the streets.

The US vice president JD Vance also sparked outrage when he spoke out against the firewall at the recent Munich Security Conference and suggested the new Trump administration would be ready to work with the AfD.

Conversely, in the run-up to the election, hundreds of thousands of Germans have protested to demand that the firewall remains.

In January, Mr Merz caused controversy when a draft motion got through parliament with AfD support, he’s since vowed he will not go into government with them.

If he sticks to that pledge then he is likely to see right-wing demonstrations as well becoming a target of prominent AfD backers including Elon Musk.

The AfD’s result also cannot be ignored. While some of the vote may be a protest, the party has expanded its traditional base in the east to pick up support in the west.

Dissatisfaction over migration, the economy, rocketing prices and the war in Ukraine have all helped to grow its ranks as people feel ignored by mainstream parties.

Mr Merz has already tried to win back some of its voters by proposing tough migration reforms including permanent checks on the borders and potentially turning away some asylum seekers when they try to enter.

If he fails to deliver on these promises then the AfD will continue to make gains.

Other urgent to dos for the next government include sorting out Germany’s economy following two years of recession and restoring its position at the centre of the EU.

Ministers must also face up to the fact their traditional allies are no longer guaranteed.

The Trump administration appears to be ripping up the rule book when it comes to being a protector of Europe and its ongoing support for Ukraine.

If America steps back, as Europe’s largest power and Ukraine’s largest European backer, Germany will have to step up.

Again, that’s going to be a big challenge as its military needs to be transformed.

The final results are not even confirmed yet but whatever form it takes, the next government knows it has four years to fix Germany, if it fails then populists are highly likely to ride to power in 2029.
