Even Healthy Ultra-Processed Foods May Change Your Insulin Response, New Study Finds

Even Healthy Ultra-Processed Foods May Change Your Insulin Response, New Study Finds

Meta description: New research suggests nutrient-matched ultra-processed foods may trigger a higher insulin response than less processed meals. Discover what the findings mean for your health.

Many people choose packaged foods labelled high in protein, rich in fibre or packed with essential nutrients because they believe these products are healthy choices. However, new research suggests that the degree of food processing may also influence how the body responds after eating.

A study reported by Medical News Today and published in Nature Metabolism found that ultra-processed meals produced a higher insulin response than less processed meals with similar nutritional content. 

What Are Ultra-Processed Foods?

Ultra-processed foods are industrially manufactured products that often contain ingredients and additives designed to improve flavour, texture, appearance or shelf life.

Common examples include packaged crisps, sugary breakfast cereals, instant noodles, fizzy drinks and certain ready-made meals. Some protein bars, packaged snacks and plant-based alternatives may also fall into this category.

However, not every processed food is unhealthy. Frozen vegetables, plain yoghurt, tinned beans and wholemeal bread can be convenient parts of a balanced diet.

What Did the New Study Discover?

Researchers at Virginia Tech investigated whether food processing could influence the body's metabolic response even when meals contained similar amounts of nutrients.

The study included 57 healthy-weight adults aged 18 to 45. Of these, 32 completed both meal-testing sessions, while 52 participated in the brain-imaging analysis.

The meals contained similar amounts of calories, carbohydrates, fat, protein, fibre and sodium, but differed in their degree of processing.

The researchers collected blood samples over the following three hours to measure changes in blood glucose and insulin. They also investigated participants' brain responses to pictures of different foods.

Ultra-Processed Meals Triggered a Higher Insulin Response

One of the study's main findings was that participants experienced a greater insulin response after eating the ultra-processed meal.

It helps regulate blood glucose by allowing cells to take up glucose from the bloodstream and supporting the body's management of energy.

Although the participants' overall blood glucose responses were similar after both meals, insulin levels remained higher following the ultra-processed meal between approximately 40 and 120 minutes after eating.

This suggests that foods with similar nutritional profiles may not always produce identical hormonal responses.

However, the researchers did not establish that the higher insulin response was harmful or that participants had developed insulin resistance. Further research is needed to understand the long-term significance of the difference.

How Did the Meals Affect Energy Use?

The researchers also observed differences in how participants used energy after eating.

Following the ultra-processed meal, participants burned fewer carbohydrates and more fat while expending more energy overall during the observation period.

The team also explored possible relationships between metabolic responses and brain activity when participants viewed pictures of food.

These findings are interesting because they suggest that food processing may influence more than the amount of protein, fat or carbohydrate listed on a nutrition label. Nevertheless, the study was small and examined responses to specific meals over a limited period.

It cannot establish whether these short-term differences lead to weight gain, diabetes or other health problems over time.

Why Nutrient Content May Not Tell the Whole Story

Traditional nutrition labels provide useful information about calories, protein, carbohydrates, fats, fibre and sodium. These details remain important when choosing food.

However, the physical structure of food, the ingredients used during manufacturing and the way a product is prepared may also influence digestion and metabolism.

For example, two meals could contain similar amounts of protein and carbohydrates but differ in texture, ingredient composition and the way the nutrients are presented within the food.

Possible explanations include differences in ingredients, food structure and digestive or hormonal signalling, but the latest study did not establish a single cause.

No. The findings should not be interpreted as proof that every packaged or ultra-processed food is harmful.

The NOVA classification system groups foods according to their degree of processing rather than measuring their overall nutritional value. As a result, foods within the same category can have very different nutritional profiles.

For instance, a packaged product fortified with vitamins and minerals may provide useful nutrients, even if it is ultra-processed. Equally, a minimally processed meal can still be unbalanced if it contains excessive amounts of salt, saturated fat or calories.

The practical message is to consider the overall diet rather than judging a food solely by its processing category or a single nutrient claim.

Simple Ways to Choose Less Processed Foods

People do not need to eliminate every packaged product to improve their eating habits. Small, realistic changes can help increase the variety of minimally processed foods in the diet.

Choose whole fruit more often: Apples, bananas, oranges and other whole fruits provide fibre and essential nutrients.

Include vegetables daily: Fresh, frozen and plain tinned vegetables can all be convenient choices.

Prepare simple meals: Eggs, beans, lentils, fish, chicken and vegetables can form the basis of nutritious meals.

Read nutrition labels: Check added sugars, sodium, saturated fat and fibre alongside protein and calorie content.

Choose whole grains: Oats, brown rice and wholemeal bread can provide fibre and other important nutrients.

Make gradual substitutions: Replace some packaged snacks with fruit, plain yoghurt or unsalted nuts when practical.

These changes can improve overall dietary quality without requiring expensive ingredients or complicated recipes.

What Does This Research Mean for Diabetes Prevention?

Insulin plays a central role in blood glucose regulation, making thestudy relevant to ongoing research into metabolic health.

However, a higher insulin response after one meal does not automatically indicate diabetes or insulin resistance. Insulin levels naturally rise after eating, and the body's response depends on several factors, including the type and amount of food consumed.

The researchers did not demonstrate that eating the tested ultra-processed meal caused diabetes or increased participants' long-term risk of developing the condition.

People concerned about diabetes should focus on established healthy habits, including regular physical activity, balanced meals, adequate sleep and appropriatemedical screening. Anyone with diabetes or another metabolic condition should follow individual advice from their healthcare professional.

What Happens Next?

Larger and longer studies will be needed to determine whether the observed metabolic differences persist across different foods, populations and eating patterns.

Researchers also need to investigate which aspects of processing matter most and whether the effects differ according to age, metabolic health or other individual characteristics.

The study provides an important starting point, but it is not a reason to panic about occasional packaged meals. Instead, it encourages scientists and consumers to look beyond nutrient numbers when evaluating food quality.

Conclusion

The new study suggests that even when two meals contain similar amounts of calories, protein, carbohydrates, fat, fibre and sodium, their degree of processing may influence the body's response after eating.

Participants experienced a higher insulin response after an ultra-processed meal, despite similar overall blood glucose responses. However, the research does not prove that the response is harmful or that all ultra-processed foods cause metabolic disease.

For everyday eating, the most practical approach is to prioritise a varied diet rich in vegetables, fruit, whole grains, beans and other nutritious foods while limiting reliance on highly processed products.

Pakistan Imposes Emergency in Khyber Pakhtunkhwa: Political Crisis Deepens as Imran Khan's PTI Government Is Suspended

Pakistan has entered a new phase of political uncertainty after President Asif Ali Zardari imposed emergency rule in Khyber Pakhtunkhwa (KP) on 11 October 2026, suspending the provincial government led The decision has intensified tensions between the federal government and the opposition at a time when security concerns and political protests are already creating pressure across the country.

The federal government says the emergency is necessary to address rising militant violence and improve coordination on counterterrorism. PTI, however, has strongly criticised the move, describing it as an attack on democracy and provincial autonomy. The decision also comes ahead of a planned PTI march towards Islamabad, where supporters intend to demand the release of Imran Khan.

UAE prosecutors claim that a Flydubai co-pilot started radicalising in Australia.

UAE prosecutors claim that a Flydubai co-pilot started radicalising in Australia.

The United Arab Emirates has revealed new details about the alleged attempted hijacking of a Flydubai passenger aircraft, saying the co-pilot accused of attacking the captain began showing signs of extremist radicalisation while studying in Australia.

The revelations have triggered further questions about aviation security, international intelligence sharing and how the 29-year-old Omani national was able to obtain work as a commercial pilot despite concerns that had reportedly emerged earlier in his career.

What Happened on the Flydubai Flight?

According to UAE prosecutors, the co-pilot, identified as Hammam al-Hammami, allegedly attacked the captain inside the cockpit with an emergency axe and attempted to seize control of the aircraft.

The situation quickly became extremely dangerous. The captain, despite being seriously injured, managed to open the cockpit door, allowing other people to intervene. An off-duty relief pilot, cabin crew members and passengers helped restrain the attacker and regain control of the aircraft.

The plane was eventually diverted and landed safely at Tabuk airport in Saudi Arabia.

Prosecutors Say the Aircraft Was Intended as a Weapon

According to prosecutors, al-Hammami allegedly intended to seize control of the aircraft and crash it into the passenger terminal at Ben Gurion Airport near Tel Aviv.

Authorities say the suspect admitted during questioning that he had acted alone, although the investigation is continuing to establish whether anyone else was involved.

Prosecutors believe those journeys were used to familiarise himself with the route and airport before the alleged attack.

Radicalisation Allegedly Began in Australia

One of the most significant revelations concerns al-Hammami's time in Australia.

Australian authorities have now launched an investigation into his time in the country and any possible links to extremist networks.

He Studied at RMIT University

Al-Hammami reportedly studied engineering at RMIT University in Melbourne but left Australia without completing the qualification.

RMIT has confirmed that he was a student between 2015 and 2017. Australian security agencies are examining what he did during that period and whether there were any warning signs or connections that should have attracted attention at the time.

The investigation does not mean that the university itself was responsible for his alleged actions.
9/11 Attacks Allegedly Influenced Him

Prosecutors say this eventually became connected to his decision to pursue a career in aviation.

Investigators also allege that he prepared himself physically and psychologically for the planned attack.

However, these claims remain part of an ongoing criminal investigation, and authorities are continuing to examine the evidence surrounding his motives and activities.

Questions Over His Aviation Career

The case has raised major questions about how al-Hammami progressed through the aviation industry.

He reportedly worked for Oman Air between 2020 and 2024, later spent several months with Royal Air Maroc in 2025 and joined Flydubai in January 2026.

Earlier reports also indicated that concerns about extremist views had emerged during his time with Oman's national airline. He was reportedly removed from flying duties and moved to an administrative position.

This has created an important question for investigators: how did someone who had reportedly attracted security concerns later become a commercial co-pilot flying an international passenger route?

How Did He Pass Security Checks?

The UAE investigation says al-Hammami met the professional and security requirements required for employment at Flydubai.

He reportedly possessed the necessary pilot licence, provided a certificate of good conduct and completed the required checks. Prosecutors said those procedures did not reveal indications of extremist beliefs or an intention to carry out an attack.

That finding is likely to become a major focus of the continuing investigation.

Aviation security depends heavily on identifying risks before an individual reaches a cockpit. The incident has therefore prompted renewed debate about whether existing background checks are capable of identifying gradual radicalisation that may not appear in conventional criminal or employment records.

Australia and New Zealand Investigate

Australia is not the only country examining al-Hammami's history.

New Zealand authorities have also launched an investigation because he reportedly received flight training there after leaving Australia.

The involvement of several countries demonstrates the international nature of modern aviation careers. A pilot can study in one country, receive flight training in another, work for several international airlines and eventually operate flights across multiple jurisdictions.

Captain and Passengers Helped Prevent Disaster

The actions of the captain, crew and passengers have received widespread attention.

Despite being seriously injured, the captain managed to help open the cockpit door. An off-duty pilot who was travelling on the aircraft noticed unusual activity around the cockpit and intervened.

Several passengers and crew members then helped restrain the suspect.

Investigation Remains Ongoing

Although the suspect has reportedly confessed to acting alone, UAE authorities have stressed that investigations are continuing.

Authorities are also investigating the suspect's background, his international travel and employment history, and the circumstancesunder which he was able to work as a commercial pilot.

What the Case Means for Aviation Security
Traditional screening systems can identify criminal records, forged documents or known security threats, but detecting gradual ideological radicalisation can be considerably more difficult.

At the same time, investigators will need to distinguish between genuine security failures and information that only became significant after the alleged attack.

Conclusion

The alleged Flydubai cockpit attack has raised serious international questions after UAE prosecutors said the co-pilot began his path towards extremism while studying in Australia.

Authorities say the 29-year-old allegedly planned to use the passenger aircraft in a suicide attack against Ben Gurion Airport and had previously flown the route to familiarise himself with the destination.

Australian and New Zealand authorities are now examining his time in their countries, while UAE investigators continue to investigate his aviation careerand whether anyone else was involved.

The incident also highlights the importance of the captain, crew, relief pilot and passengers who intervened during the flight. Their actions helped prevent a potentially catastrophic outcome and will remain a central part of the investigation into one of the most serious aviation security incidents of 2026.

Human Milk Provides a New Window Into Mammary Gland Function and Infant Growth

Human Milk Provides a New Window Into Mammary Gland Function and Infant Growth

Human breast milk may reveal much more than what a baby is eating. New research suggests that milk can provide scientists with a valuable, non-invasive window into the biological condition of the mammary gland and may help explain how maternal nutrition is connected with infant growth.

The study, led by researchers at NYU Grossman School of Medicine and published online in Science, examined thousands of molecular measurements in human milk from mothers in three geographically and nutritionally diverse populations. Researchers found molecular patterns that were associated with maternal nutritional status, mammary gland function and infant growth.
