Cancer doctor: Ice cream can be part of a long and healthy life

16. July, 2026

According to oncologist and bioethicist Zeke Emanuel, living a long and healthy life is not about expensive wellness trends but about simple habits backed by scientific evidence, NPR reports.

A simple approach to health

According to Emanuel, many popular wellness products are expensive and lack strong scientific support.

Instead, he has chosen a simpler approach to maintaining good health.

More fiber benefits the body

Emanuel recommends eating more fiber, as it helps support the beneficial bacteria in the gut.

Fermented foods matter

Yogurt, cottage cheese, kimchi, and sauerkraut are among the foods he highlights as excellent choices for maintaining a healthy gut microbiome.

Sleep should be a priority

Emanuel describes sleep as a fundamental part of a healthy lifestyle.

It plays a vital role in brain function, memory, and the body’s ability to repair itself.

Too little sleep can lead to weight gain

A recent study published in Annals of Internal Medicine found that people who consistently slept too little for six weeks began to gain weight.

Sleep deprivation also affects the hormones that regulate hunger.

Keep your body active

Regular exercise is another key recommendation from Emanuel.

Both cardiovascular exercise and strength training are important, while taking a walk after a meal may help stabilize blood sugar levels.

Work provides structure

One of Emanuel’s most debated recommendations is to avoid retiring completely.

He believes that work provides structure, mental stimulation, and valuable social connections.

Having a sense of purpose

For those who leave the workforce, Emanuel recommends creating a meaningful daily routine with a clear sense of purpose.

Research published in The American Journal of Geriatric Psychiatry suggests that people with a strong sense of purpose have a lower risk of cognitive decline.

Volunteering can make a difference

Emanuel points to volunteering, teaching, or joining a club as ways to build social connections while continuing to use one’s skills and experience.

Social conversations matter

He encourages people to take the initiative to engage in conversations with others.

Even brief encounters and casual conversations can have a positive impact.

Avoid unnecessary risks

Emanuel advises avoiding smoking and vaping, limiting alcohol consumption, avoiding distracted driving, and staying away from activities that carry a high risk of serious injury.

Keep learning

According to Emanuel, curiosity and lifelong learning help keep the brain active and may reduce the risk of cognitive decline.

Ice cream does not have to be off-limits

Emanuel believes that enjoying an ice cream can fit into a healthy lifestyle.

However, he emphasizes that moderation is essential.

Research points to the ice cream paradox

He refers to research published in BMC Medicine indicating that people who eat ice cream more frequently appear to have a lower risk of metabolic diseases.

This phenomenon has become known as the “ice cream paradox.”

Dairy products may play a role

According to Emanuel, data from 2015 suggest that dairy products may help reduce the risk of developing type 2 diabetes.

At the same time, the research does not establish a direct cause-and-effect relationship.

Whey protein may be part of the explanation

Dairy products contain whey protein, which may help regulate blood sugar levels.

This could be one explanation for the findings.

New study: Vaping may affect your blood vessels

New study: Vaping may affect your blood vessels

The use of e-cigarettes has increased in several countries, with more people taking up vaping, according to The Sun.

At the same time, several countries are introducing new rules on packaging, colors, and flavor options to make these products less appealing, particularly to people who do not smoke.

Although e-cigarettes are generally considered less harmful than traditional cigarettes, researchers still do not know enough about their long-term effects.

Researchers tested participants

A study conducted by Manchester Metropolitan University and published in ERJ Open Research, as cited by The Sun, examined 75 people aged 30 or younger.

The participants were divided into three groups: smokers, e-cigarette users, and people who neither smoked nor vaped.

They completed a cycling test on a stationary bike while researchers measured, among other things, oxygen uptake, blood samples, and blood vessel function.

According to the study, both smokers and e-cigarette users became short of breath more quickly than participants with no nicotine habits.

The difference was significant

The researchers also found evidence that the blood vessels of e-cigarette users functioned less effectively.

This may make it more difficult for the body to transport oxygen during physical activity, potentially leading to earlier fatigue.

People who used e-cigarettes had around 15 percent lower physical capacity than those who neither smoked nor vaped.

According to the researchers, vaping may therefore affect the lungs and cardiovascular system in a way that resembles the effects of tobacco smoking.

Pythons could help shape the next generation of medicines

Pythons could help shape the next generation of medicines

Researchers are not only searching for new treatments in laboratories. They are also studying animals that have developed unique abilities through evolution.

According to NPR, such traits could inspire new medicines.

A research team from the University of Colorado Boulder has therefore spent several years studying pythons.

The researchers aim to understand how the snakes’ bodies function and whether that knowledge can be applied to medical research.

The body responds differently

Pythons can survive for long periods without food. When they finally eat, their metabolism increases dramatically, and several of their organs temporarily increase in size.

After some time, the organs return to their normal state.

According to NPR, the researchers hope this process could provide new insights into heart disease in humans.

The scientists are also investigating a molecule whose concentration rises sharply in the snakes’ blood after a meal.

A study published in the journal Nature Metabolism found that the molecule caused obese mice to eat less and lose weight.

The researchers therefore plan to investigate whether it could be used in future treatments.

Could lead to new medicines

Pythons also lose very little muscle strength, even though they can fast for several months.

According to NPR, researchers are investigating whether this ability could be used to develop treatments for muscle wasting.

The scientists emphasize that the research is still at an early stage.

Nevertheless, the findings suggest that the unique biology of pythons could become an important source of new knowledge for the treatment of conditions including heart disease, muscle loss, and obesity, NPR reports.

New powder stops severe bleeding in seconds

New powder stops severe bleeding in seconds

Many of the products currently used work best on flat wounds.

They can be difficult to use on deep or irregular injuries, and some are sensitive to heat and moisture, according to Science Daily.

Researchers have therefore developed a powder that can adapt to different types of wounds.

The powder can also be stored for at least two years without losing its effectiveness, even in hot and humid conditions.

Different trials

The powder is made from naturally derived materials. When it comes into contact with blood, it quickly forms a gel that seals the wound.

According to the scientific study published in Advanced Functional Materials, laboratory tests showed that the material is gentle on blood cells and has antibacterial properties.

Animal studies also showed faster wound healing and reduced blood loss compared with existing products.

Can stop bleeding in one second

In the study, the powder was able to stop severe bleeding in about one second by rapidly forming a protective gel over the wound.

The technology was originally developed for use on the battlefield, but researchers believe it could also be be used in ambulances, hospitals, and during natural disasters.

These groups face a higher risk when swimming in warm sea water

These groups face a higher risk when swimming in warm sea water

Health experts say the likelihood of infection rises when sea temperatures exceed 20°C, particularly during extended periods of hot summer weather.

As coastal waters continue to warm, cases of bacterial infections could become more common.

Although these infections remain rare, they can be serious in some cases.

Warm water encourages bacterial growth

The bacteria thrive in warm coastal waters with relatively low salinity and are most active during the summer months, especially in July and August.

Health data show that infections occur most frequently among adults aged 65 to 79, although people of any age can be affected.

Who is most at risk?

People with open cuts, wounds, or weakened immune systems are at greater risk because the bacteria can enter the body through damaged skin.

Most infections affect the skin and soft tissue around a wound.

In rare cases, however, the bacteria can spread into the bloodstream, leading to a severe and potentially life-threatening illness.

Health authorities advise anyone who develops a fever, increasing pain, swelling, or severe redness around a wound after swimming in the sea to seek medical attention promptly.

People in higher-risk groups should consider avoiding swimming when sea temperatures rise above 20°C.

If they do enter the water, any cuts or wounds should be properly covered and cleaned thoroughly afterward.

Early warning signs in your eyes that could signal cancer

Early warning signs in your eyes that could signal cancer

Eye cancer can be difficult to detect because its symptoms are not always obvious.

Some cases are only discovered during a routine eye examination, according to Cancer Research UK.

Bulging eye

One possible symptom is that one eye begins to protrude more than usual.

This change may develop gradually over time and should be examined by a healthcare professional.

Partial or complete vision loss

Eye cancer can cause vision to deteriorate or result in partial or complete vision loss.

If your vision changes without an obvious explanation, it should be taken seriously.

Pain in or around the eye

Pain in or around the eye can occur, but it is a relatively uncommon symptom of eye cancer.

Most people with the disease do not experience pain in its early stages.

Pale raised area on the surface of the eye

A pale, raised lump on the conjunctiva or cornea may be a possible symptom.

This change may be visible on the surface of the eye and should be assessed by a healthcare professional.

Blurred vision

Blurred or unclear vision can be one of the signs of eye cancer.

If your vision remains blurred, it is important to have your eyes examined.

Changes in the appearance of the eye

A change in the appearance of the eye may be a symptom of the disease.

It may involve a visible change that was not previously present.

Lump on or around the eyelid

A lump on the eyelid or around the eye may be a possible sign of eye cancer.

This is a change that should be examined further.

Spots or flashes of light in your vision

Some people experience spots, flashes of light, or wavy lines in their field of vision.

These visual disturbances may be among the possible symptoms.

Reduced peripheral vision

The disease can cause a loss of peripheral vision while central vision remains clear.

This means you may have difficulty seeing objects located to the sides.

Dark spot on the iris

A dark spot on the colored part of the eye may be a symptom, especially if it increases in size over time.

Such a change should be evaluated by a doctor or an optometrist.

Irritation or red eye

Persistent irritation, a red eye, or chronic inflammation of the conjunctiva may also be symptoms.

If these symptoms do not go away, it is important to have them examined.

Pain may be caused by increased pressure

If pain develops, it may be because the cancer has spread beyond the eye or because the pressure inside the eye has become too high.

Get your symptoms checked

Eye cancer is a rare disease, and many of its symptoms can also be caused by other eye conditions.

For this reason, it is recommended that you contact a general practitioner or an optometrist if you experience one or more of these symptoms.

Early detection can improve treatment

The earlier eye cancer is detected, the easier it is generally to treat.

An early diagnosis also increases the likelihood that treatment will be successful.

New research reveals inequality in cancer screening among LGBTQ+ people

New research reveals inequality in cancer screening among LGBTQ+ people

The study, published in the journal Cancer, is based on responses from nearly 664,000 adults in the United States, of whom around 1.6 percent identified as LGBTQ+.

Participants were asked, among other things, whether they had undergone the recommended cancer screenings.

The researchers examined several types of cancer screening. However, they found no significant differences in colorectal cancer screening.

Barriers in the healthcare system

According to the researchers, the differences may be due to barriers within the healthcare system.

They point out that more inclusive language and better training for healthcare professionals could make it easier for more people to participate in screening programs.

The study also notes that alternative methods, such as HPV self-testing for some transgender individuals, may help.

The researchers believe that these measures could improve access to preventive cancer screening.

Lower participation

The results show that lesbian and bisexual women were 16 percent less likely to have undergone breast cancer screening and 8 percent less likely to have received cervical cancer screening than heterosexual women.

The difference was even greater for transgender individuals.

They were 76 percent less likely to have undergone breast cancer screening and 42 percent less likely to have received cervical cancer screening compared with cisgender individuals.

According to the researchers, the findings indicate that inequalities in access to preventive cancer screening persist.

New study: Iron supplements may reduce aggressive behavior

New study: Iron supplements may reduce aggressive behavior

The first years of life are crucial for brain development, and iron is essential for the brain to develop and function normally.

At the same time, researchers are still unable to measure how much iron is available in the brain itself.

Blood tests only show the body’s overall iron levels, Umeå University said in a press release sent to VIA.

The researchers therefore plan to follow up with the same children when they are eight years old to determine whether the findings remain consistent over the longer term.

Researchers urge caution

The study, published in Scientific Reports, included 221 healthy children from Sweden and Poland.

Half of the children received a small daily iron supplement from the age of four to nine months.

The other half received a placebo, a supplement containing no active ingredients.

The researchers emphasize that the findings are not sufficient to recommend iron supplements for all infants.

According to Umeå University, further studies are needed, including research that takes factors such as genetics and upbringing into account.

Effects appeared later

When the children reached the age of three, their behavior was assessed.

The results showed that children who had received iron supplements displayed fewer aggressive and externalizing behavioral problems than those in the placebo group.

The researchers also examined difficulties with concentration and withdrawn behavior.

At the same time, they found that the iron supplements had not reduced the risk of iron deficiency as measured by blood tests.

The findings therefore suggest that iron may influence brain development in ways that cannot be detected through blood tests.

How to boil new potatoes to perfection

Ida-Marie Palm Varbæk

16. July, 2026

According to chef Lisa Gudberg Ballisager from Denmark, timing within the growing season is important.

She explains that new potatoes harvested later in the season have spent more time in the ground, giving them a richer flavour than the first potatoes to reach the market.

At the same time, prices tend to fall as the season progresses, making them more affordable.

She also notes that new potatoes differ from winter potatoes because they have a milder flavour and a subtle natural sweetness.

Preparation matters

Lisa Gudberg Ballisager recommends leaving the skins on new potatoes.

Instead, they should be washed thoroughly and gently scrubbed clean, as the skins contain both flavour and valuable nutrients.

Place the potatoes in cold, salted water before bringing it to a boil.

They only need to cook for a few minutes, depending on their size, before being left to rest briefly in the hot water. Leaving them in the water for too long can make them soft and watery.

The chef’s advice

Lisa Gudberg Ballisager says this is the ideal time to enjoy new potatoes.

In her view, they offer the best balance of flavour and value at this stage of the season.

For that reason, she believes even people who do not usually choose potatoes should consider giving fresh new potatoes a try.

How fish oil can affect your blood pressure if you eat it regularly

How fish oil can affect your blood pressure if you eat it regularly

Fish oil is a major source of omega 3 fatty acids, but research has not reached a clear conclusion about how much fish oil supplements affect blood pressure. Several factors may influence any potential benefit, reports Health.

Omega 3 is known for its heart health benefits

Fish oil contains omega 3 fatty acids that have long been associated with heart health. They are particularly well known for helping lower triglyceride levels.

Research findings are mixed

Studies examining fish oil and blood pressure have produced inconsistent results. Some have reported modest reductions in blood pressure, while others have found no meaningful effect.

People with high blood pressure may benefit the most

A 2022 analysis found that consuming 2 to 3 grams of omega 3 fatty acids per day was associated with a modest reduction in blood pressure. The greatest benefit was observed among people with elevated blood pressure.

Normal blood pressure is usually unchanged

According to experts, people with normal blood pressure generally experience little or no change in their blood pressure when taking fish oil supplements.

Fish oil may also have side effects

Fish oil is generally well tolerated, but some people experience a fishy aftertaste or heartburn. More serious concerns that have been reported include a possible increased risk of atrial fibrillation, stroke, elevated LDL cholesterol, and bleeding complications.

Supplements are not regulated like prescription medicines

Unlike prescription medications, dietary supplements are not reviewed for safety and effectiveness before reaching the market. Experts recommend choosing products that have been tested by an independent third party for quality and accurate labeling.

Food is the preferred source of omega 3

Experts generally recommend getting omega 3 from food instead of supplements. Good sources include salmon, mackerel, albacore tuna, trout, and sardines, while the American Heart Association recommends eating two 3.5 ounce servings of fatty fish each week.

Fish oil products are not all the same

Fish oil supplements contain different amounts of the omega 3 fatty acids DHA and EPA. This variation may help explain why studies have produced different results.

The dose may make a difference

Researchers have tested a wide range of fish oil doses. Some appear to influence blood pressure, while others do not, so the role of dosage remains uncertain.

Fish oil may improve blood vessel function

Studies that have reported positive effects suggest that fish oil may help blood vessels relax and widen. This could improve how blood vessels function.

Omega 3 may reduce oxidative stress

Researchers also believe omega 3 fatty acids may reduce oxidative stress. Free radicals can damage cells and are thought to contribute to elevated blood pressure.

Lifestyle has a greater impact

Experts say healthy eating and lifestyle habits have a greater effect on blood pressure than fish oil supplements. Prioritizing sleep, exercising regularly, limiting sodium and alcohol, and managing stress are all recommended.

Speak with a healthcare professional first

Before starting a fish oil supplement, it is recommended to consult your doctor or a pharmacist. They can help assess the potential benefits and risks based on your health and any medications you are taking.
