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.

Bitcoin’s physical infrastructure is the industry’s most overlooked asset

Bitcoin’s physical infrastructure is the industry’s most overlooked asset

Opinion by: Scott Buchanan, chief operating officer of Bitcoin Depot

A new proposal to install Bitcoin ATMs in federal buildings highlights an important question: Can crypto truly go mainstream without a stronger physical presence? For years, the industry has focused on software and decentralization, but its reluctance to invest in real-world infrastructure is starting to show. Without physical access points, crypto risks becoming an exclusive, insiders-only system, rather than the open alternative it sets out to be.

Everyone loves to talk about decentralization. There’s a good reason behind this. It defines the movement, shapes the technology, and supports the vision of a better financial system. While the industry focuses on code and algorithms, it lacks something basic. A decentralized system that exists only online is not genuinely decentralized.

Physical infrastructure is the missing link

Bitcoin’s physical infrastructure is the missing link. Without tools like ATMs, kiosks and access points at traditional retail locations, crypto remains out of reach for millions. Decentralization is not just about removing intermediaries. True decentralization requires expanding access. Without real-world touchpoints, even the most advanced network becomes limited to a closed circle of insiders.

For crypto to become mainstream, it must be easy to reach digitally and physically. That means showing up in places people already go and seamlessly integrating into people’s lives. Many groups in the American population still rely on cash or don’t have access to traditional banks. According to the latest Federal Deposit Insurance Corporation report, around 5.6 million American households don’t have a bank or savings account. Bitcoin ATMs give these users access without needing an app, a bank account or a crash course in blockchain. Most crypto tools today assume a level of financial fluency and infrastructure that millions simply do not have. The result is a digital-only ecosystem that locks out newcomers and widens the divide between early adopters and everyone else.

User-friendly screen in the right place

Physical infrastructure helps address this issue. A Bitcoin ATM in a grocery store or gas station is not just a convenience but a bridge to financial inclusion. It is an invitation to someone who has never bought crypto, telling them they can participate. No bank, no broker, just a user-friendly screen in a familiar place.

These machines also generate new economic activity. Local businesses benefit from increased foot traffic as the kiosks create passive revenue. For many communities, they provide access to a parallel financial system that was previously out of reach. This is a tangible example of crypto’s real-world utility. It is already happening, and it is measurable.

The crypto industry’s blind spot

The industry often treats physical infrastructure like an afterthought. The obsession with building new digital solutions has created a blind spot. Innovation without usability builds systems that serve the few but exclude the many. If someone can buy Bitcoin (BTC) at the same place they buy their morning coffee, that is when crypto stops feeling like an obscure digital asset and starts becoming part of everyday life.

As governments increase regulation, trusted and transparent interfaces will become more important. When operated within regulatory frameworks, Bitcoin ATMs offer a way to provide access between traditional finance and digital assets. They are familiar, easy to monitor and offer a more approachable entry point for the general public.

Like any financial tool, Bitcoin ATMs have drawn scrutiny, particularly in cases where bad actors use them. Rather than dismissing the machines themselves, we should focus on investing in better oversight, stronger consumer education and smarter regulation. The overwhelming majority of people who use Bitcoin ATMs do so for legitimate reasons: to send remittances, to move money securely or to access digital assets without traditional banking barriers. Building trust does not mean avoiding or dismantling physical access, but improving it.

The first time someone uses Bitcoin should not involve reading a white paper or navigating a tutorial. It should be as familiar as using an ATM or tapping a payment terminal. This is not an argument against innovation. Software and protocols will continue to evolve and play an important role. Physical infrastructure provides something those tools cannot: trust through presence. When people can see and use crypto in their neighborhood, at a store they already visit or in a format they already understand, it changes how they think about crypto and who it is for.

According to Coin ATM Radar, there are over 30,000 Bitcoin ATMs in the US. It’s a meaningful start, but still only a small step toward widespread access.

Crypto’s long-term success will depend not just on innovation but also on inclusion. That means building more than networks; it means building presence. When people can interact with crypto in the physical world, it stops being abstract and becomes usable. That is how digital finance becomes everyday finance.

Polygon-backed, high-yield blockchain launches for institutional adoption

Polygon-backed, high-yield blockchain launches for institutional adoption

The Katana Foundation, a nonprofit focused on decentralized finance (DeFi) development, is launching its private mainnet, aiming to unlock greater crypto asset productivity via deeper liquidity and higher yields for users.

The Katana Foundation launched a DeFi-optimized, private blockchain, Katana, on May 28, incubated by GSR Markets and Polygon Labs, with the public mainnet launch set for June.

The new blockchain will enable users to earn higher yields and explore DeFi in a “unique, optimized yield environment” that unlocks latent value through an ecosystem that makes every digital asset “work harder,” according to an announcement shared with Cointelegraph.

“DeFi users deserve ecosystems that prioritize sustainable liquidity and consistent ‘real’ yields,” wrote Marc Boiron, the CEO of Polygon Labs and core contributor at Katana, adding:

“Katana’s user-centric model turns inefficiencies into advantages, establishing a truly positive-sum environment for builders and participants alike.”

Katana aims to solve the crypto industry’s liquidity fragmentation issue, which can cause significant price slippage, as one of the main barriers limiting institutional DeFi participation

To reduce the value slippage in DeFi, Katana’s blockchain concentrates the liquidity from numerous protocols and collects yields on all potential sources to create an ecosystem with deeper liquidity and more predictable lending and borrowing rates.

Institutional participation in DeFi is set to triple over the next two years to 75% from 24% of 350 surveyed institutional investors, according to management consulting firm EY-Parthenon.

To tackle the growing institutional liquidity needs, Katana’s liquidity pool is composed of multiple protocols, including lending protocol Morpho, decentralized exchange (DEX) Sushi and perpetual DEX Vertex, enabling users to trade “blue-chip assets” without needing crosschain transfers.

Katana has also incorporated Conduit’s sequences and Chainlink’s decentralized oracle network.

Katana to compound DeFi yield from “Ethereum-based opportunities”

Katana aims to boost sustainable yield by building a cohesive DeFi ecosystem. For instance, VaultBridge deploys bridged assets into overcollateralized, curated lending strategies on Ethereum via Mopho to earn yield, which is routed back and compounded on Katana.

The protocol will reinvest network fees and a portion of application revenue back into its ecosystem.

“This reduces reliance on short-term incentives, generates consistent yield, and as it grows, acts as an increasingly stable backstop during periods of volatility and liquidity shocks,” Polygon Labs’ Boiron told Cointelegraph, adding:

“Yield is distributed pro-rata to each chain using VaultBridge protocol based on their share of total deposits into VaultBridge.”

“So if Katana supplies 20% of the total vault deposits, it receives 20% of the yield back,” he added.

Katana will subsequently allocate its share of yield to users through boosted DeFi incentives across “core apps” such as Sushi, Morpho or Vertex. The yield is generated from “Ethereum-based opportunities and then enhanced through Katana’s core applications,” said Boiron.

Polygon Labs’ CEO previously criticized DeFi protocols for fueling a cycle of “mercenary capital” by offering sky-high annual percentage yields (APYs) through token emissions.

Beyond infrastructure-related limitations, regulatory uncertainty remains another significant barrier to institutional DeFi adoption.

Regulatory concerns were the main barrier to entry, flagged by 57% of institutional investors as the main reason for not planning to participate in DeFi activities.

Hamas’s Gaza chief ‘eliminated’, says Netanyahu – but military sources say they cannot confirm death

Hamas's Gaza chief 'eliminated', says Netanyahu - but military sources say they cannot confirm death

Hamas’s Gaza chief Mohammed Sinwar has been “eliminated”, according to Israel’s Prime Minister Benjamin Netanyahu.

But Israeli military sources have said they are not yet able to confirm the death.

Hamas has also not yet confirmed the apparent killing of its leader.

Meanwhile, with Gaza on the brink of famine, the Palestinian ambassador to the United Nations broke down in tears as he spoke of the suffering of its people.

Riyah Mansour told the Security Council: “Children are dying of starvation. The images of mothers embracing their motionless bodies. Caressing their hair, talking to them, apologising to them, is unbearable.”

He added: “I have grandchildren. I know what they mean to their families. And to see this situation over the Palestinians without us having hearts to do something is beyond the ability of any normal human being to tolerate. Flames and hunger are devouring Palestinian children. This is why we are so outraged as Palestinians everywhere.”

Sinwar was one of Israel‘s most wanted and the younger brother of the Palestinian militant group’s former leader Yahya Sinwar.

The older sibling was the mastermind of the October 7 2023 attack, which killed 1,200 people in Israel, with around 250 others taken hostage into Gaza.

The attack triggered Israel’s assault on Gaza which decimated the territory, with more than 53,000 people killed, mostly women and children, and over two million displaced, according to health officials, who do not distinguish between civilians and combatants in their tally of fatalities.

Yahya Sinwar was killed in a gun battle with Israeli troops in Gaza last October. His younger sibling was believed to have then become the head of Hamas’s armed wing.

Speaking to the Knesset on Wednesday, Mr Netanyahu included Mohammed Sinwar in a list of Hamas leaders killed in Israeli strikes. Later, Israel Defence Forces (IDF) sources said they were not yet able to confirm the death.

The prime minister said: “We have killed tens of thousands of terrorists. We killed (Mohammed) Deif, (Ismail) Haniyeh, Yahya Sinwar and Mohammed Sinwar.” He did not elaborate.

Mohammed Sinwar had reportedly been the target of an Israeli strike on a hospital in southern Gaza on 13 May and Mr Netanyahu said on 21 May that it was likely he had been killed.

The Israeli military had said it struck a Hamas command centre under the European Hospital in the Sinwars’ hometown of Khan Younis, and it declined to comment on whether Sinwar was targeted or killed.

At least six people were killed in the strike and 40 wounded, Gaza’s health ministry said at the time.

Sinwar rose through ranks

Like his older brother, Mohammed Sinwar joined Hamas after it was founded in the late 1980s as the Palestinian branch of the Muslim Brotherhood. He became a member of the group’s military wing, known as the Qassam Brigades.

👉Listen to The World with Richard Engel and Yalda Hakim on your podcast app👈

Sinwar rose through the ranks to become a member of its so-called joint chiefs of staff, bringing him close to its longtime commander, Deif, who was killed in a strike last year.

“In the last two days, we have been in a dramatic turn towards a complete defeat of Hamas,” the Israeli leader told the Knesset.

Mr Netanyahu also spoke about how Israel was “taking control of food distribution”, a reference to a new aid distribution system that has been criticised and boycotted by humanitarian groups and the UN.

One killed at site of aid hub

The development comes after one person was killed and 48 others injured when forces opened fire on a crowd that overwhelmed an aid hub in Gaza, according to local health officials.

Palestinians have become increasingly desperate for food after almost three months of Israeli border closures. A blockade has recently been eased.

People broke through fences around the distribution site on Wednesday, and a journalist with the Associated Press said they heard Israeli tank and gunfire, and saw a military helicopter firing flares.

It was not yet known whether the death and injuries were caused by Israeli forces, private contractors or others.

The Israeli and US-backed Gaza Humanitarian Foundation, which set up the hub outside Rafah, said its military contractors had not fired on the crowd but “fell back” before resuming aid operations. Israel said its troops nearby had fired warning shots.

The UN and other humanitarian organisations have rejected the new system, saying it will not meet the needs of Gaza’s 2.3 million people and allows Israel to use food to control the population.

Israel has vowed to seize control of Gaza and fight until Hamas is destroyed or disarmed and exiled, and until the militant group returns the last 58 hostages, including around a third thought to be still alive.

‘This is a man-made catastrophe’

Meanwhile, a US trauma surgeon who has been working in Gaza urged the UN Security Council to not “claim ignorance” about the humanitarian devastation.

Dr Feroze Sidhwa said: “Let’s not forget, this is a man-made catastrophe. It is entirely preventable. Participating in it or not allowing it to happen is a choice.

“This is a deliberate denial of conditions necessary for life: food, shelter, water and medicine. Preventing genocide means refusing to normalise these atrocities.”

The UN World Health Organization has documented around 700 attacks on healthcare facilities in Gaza during the war. Israel accuses Hamas of using hospitals as command centres and to hide fighters.
