David Petrus Ibars/Getty ImagesA new study finds that higher ultra-processed food (UPF) intake is associated with an increased body mass index (BMI).The link between UPFs and higher BMI was most pronounced for soda consumption.The findings also demonstrate how adherence to the Mediterranean diet may impact BMI.The study is relatively small but builds on existing evidence showing the health dangers of consuming ultra-processed foods.

Although ultra-processed food (UPF) is a relatively new term, it has already become a household name. Every new study makes it clearer that many of these products are harmful to human health.

The latest in a long line of studies shows that people who consume more UPFs are more likely to have a higher BMI and increased adiposity the amount of excess fat an individual has.

The Italian study, recently published in the journal Nutrients, also shows that people who follow the Mediterranean diet the least closely are more likely to have a higher BMI. Ultra-processed foods linked to higher BMI, obesity

For this study, researchers recruited 175 people with obesity, all of whom completed a food diary, providing information about their UPF intake and how closely they followed the Mediterranean diet. The scientists also measured their body composition and BMI.

According to their analysis: The data showed an increase in UPF consumption as the BMI increased.

In other words, individuals who consumed the highest amounts of UPFs were more likely to have a higher BMI. At the same time, as UPF intake increased, adherence to the Mediterranean diet decreased.

The scientists found that some UPFs were more closely linked to BMI and adiposity than others, notably soda. This is not the first time soda has been singled out.

Although the recent study is relatively small, it is yet more evidence that reducing UPF intake particularly soda is probably a smart move for health.

The study confirmed what we emphasize to our weight loss patients: Focus on adding lean proteins and vegetables to the diet, Mir Ali, MD, a board certified general surgeon, bariatric surgeon, and medical director of MemorialCare Surgical Weight Loss Center at Orange Coast Medical Center in Fountain Valley, CA, told Healthline.

The more processed the food, he continued, the more it stimulates insulin secretion and fat deposition.

Ali noted that processed foods take less energy to break down and make the person feel hungry sooner. He also told us that highly processed foods can trigger addictive eating behaviors. For all these reasons, limiting UPFs can greatly help a person in their weight loss efforts, he said. Ultra-processed foods linked to multiple chronic diseases

In the United States, more than half of calories consumed are in the form of ultra-processed foods (UPFs).

According to NOVA, the most commonly used classification system for food processing, UPFs are:

Industrially manufactured food products made up of several ingredients (formulations) including sugar, oils, fats, and salt (generally in combination and in higher amounts than in processed foods) and food substances of no or rare culinary use (such as high-fructose corn syrup, hydrogenated oils, modified starches, and protein isolates).

This means UPFs tend to contain large quantities of sugar, fat, and a list of ingredients you would not find in a standard home kitchen. UPFs are produced industrially, are relatively low cost, and have a long shelf life, all of which make them convenient for the customer and the manufacturer. Importantly, theyre also highly palatable and easy to overeat.

In recent years, researchers have linked higher intakes of UPFs to a host of chronic health conditions, including diabetes, cancer, and heart disease.

For instance, a recent study found that greater UPF intake was associated with type 2 diabetes. However, when the researchers broke down their analysis by food type, not all UPFs were as tightly linked to the condition. The closest ties were with sodas, savory snacks, animal-based products, and ready-to-eat dishes.

Additionally, there may be a link between highly processed foods and mental health conditions like depression.

Because of the growing evidence that UPFs are closely linked to worse health outcomes, many experts are calling for stricter regulations on these foods, like sugar taxes and warning labels on packages. However, it remains to be seen whether such restrictions in the ultra-processed food industry will take effect. Reducing ultra-processed food intake

The results of the recent study echo other research on the benefits of a Mediterranean diet for overall health and weight management.

Federica Amati, PhD, MPH, a postdoctoral medical scientist and registered public health nutritionist with the Association for Nutrition (AfN), suggested making dietary changes slowly, particularly when it comes to reducing ultra-processed food intake.

Its clear that certain UPFs are worse for our health than others, so if youre looking to cut down, start with the worst offender: soda. The evidence of links between high intakes of soda and poor health outcomes is now overwhelming. So, if you can cut it out of your diet, youll be doing your health a huge favor, Amati told Healthline.

She recommended replacing soda with water with optional added fruit. Or even better, switch to kombucha a type of fermented tea, which contains live microbes. We know that fermented foods are likely to support your gut health and overall health, she suggested.

If youre cutting back on your UPF intake, Amati continued, you dont have to forgo all of your favorite foods you can still enjoy chocolate, for instance. She suggested looking for products that are at least 75% cocoa with as few ingredients on the label as possible.

Dark chocolate, she explained, is rich in antioxidants and other beneficial plant compounds. So, if you choose the right kind, and eat it in moderation, it can actually benefit your health.

Finally, chips are high in salt and fat and contain no useful nutrients. I suggest swapping these for minimally processed popcorn. Because popcorn is made from whole grains, it contains nutrients, including fiber, which most of us dont consume nearly enough of.

Just make sure you select a product that doesnt contain a raft of additives, sugar, and salt, she advised.

If youre interested in learning more about the benefits of the Mediterranean diet or need additional guidance for reducing your intake of UPFs, talk with your doctor for further guidance. Takeaway

A new study shows increased UPF intake is associated with higher BMI and greater overall adiposity.

Although the study is relatively small, it adds to the growing evidence that overall UPF intake particularly soda intake is linked to worse health outcomes.

At the moment, most of us eat around 60% of our calories as UPFs, Amati said. Removing those products entirely would be nearly impossible, especially if we tried to do it all at once. Instead, make small sustainable changes, with the goal of reducing your total energy intake to around 20% from UPFs.

A good place to start is by replacing the UPFs that are highest in energy, like sodas and pastries, Amati concluded.

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.

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 BESS subsystem to be Bauma highlight

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.

Follow live: Germany’s election results

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”.

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.
