New research: High salt intake may affect memory

13. July, 2026

Researchers followed more than 1,200 older Australians with normal memory and cognitive function over a six-year period.

Participants answered questions about their diet and completed tests of memory, attention, language, and other cognitive abilities every 18 months.

The study was published in the journal Neurobiology of Aging and was reported by Prevention.

Indirect effects on the brain

A high salt intake is already known to increase the risk of high blood pressure.

According to dietitians Jennifer Pallian and Lauri Wright, it can damage blood vessels and increase inflammation in the body, Prevention reports.

Over time, this may affect brain function and memory.

Neurologist Alexander Zubkov also told Prevention that consuming too much sodium may reduce blood flow to areas of the brain that are important for memory.

The World Health Organization recommends that adults consume less than 2,000 milligrams of sodium per day.

One group stood out

The researchers did not find a clear link between high salt intake and poorer cognitive abilities across all participants.

However, when they analyzed men and women separately, a difference emerged.

Older men with a high salt intake experienced a greater decline in episodic memory, which is the ability to remember personally experienced events.

According to the researchers, the study cannot prove that salt is the cause because it is an observational study.

However, the findings support existing evidence suggesting that a high salt intake may affect brain health over time.

How eating green bananas affects your body

How eating green bananas affects your body

Green bananas may look unripe, but that does not necessarily make them a poor choice.

Experts told Fox News that both green and ripe bananas offer health benefits, depending on your nutritional needs.

Green bananas are still worth eating

Even if a banana stays green for a long time, it can still be perfectly edible and provide valuable nutrients.

Early harvesting can affect ripening

If bananas are harvested before they are mature enough, they may struggle to develop the ideal flavor and texture.

The shape can reveal ripeness

According to an expert, less ripe bananas tend to have more angular edges, while ripe bananas are typically more rounded.

Cold temperatures can stop the ripening process

Storage or transportation at temperatures that are too low can interfere with a banana’s natural ripening process.

Cold damage can keep bananas green

Exposure to cold can cause bananas to remain green or greenish-yellow, even after extended storage.

The right temperature is important

Experts told Fox News that bananas should ideally be stored at temperatures between 13°C and 15°C (55°F to 59°F) to prevent damage and allow normal ripening.

Both types contain important nutrients

Both green and ripe bananas provide potassium, vitamin B6, vitamin C, and a range of other essential nutrients.

Green bananas contain more resistant starch

Green bananas contain higher levels of resistant starch, which is digested more slowly and functions in a way that is similar to dietary fiber.

They are less sweet

Because of their higher resistant starch content, green bananas generally have a less sweet taste than ripe bananas.

They may have a gentler effect on blood sugar

According to a dietitian speaking to Fox News, green bananas may have a more moderate impact on blood sugar levels than ripe bananas.

Ripening converts starch into sugar

As bananas ripen, much of their resistant starch is gradually converted into natural sugars.

Ripe bananas are softer and sweeter

As a banana ripens, it becomes softer in texture and sweeter in flavor. Many people also find ripe bananas easier to digest.

The best choice depends on your needs

If you are looking for more resistant starch or want to better manage your blood sugar levels, a green banana may be the better option.

If you prefer a sweeter fruit that is gentler on the stomach, a ripe banana may be the better choice.

Consider your overall diet, not just the banana’s color

The dietitian also recommends viewing bananas as part of your overall diet rather than focusing solely on whether they are green or ripe.

Study of 2.4 million cases finds men more likely to receive late cancer diagnosis

Study of 2.4 million cases finds men more likely to receive late cancer diagnosis

A U.S. study published in Cancer Epidemiology, Biomarkers & Prevention, based on 2.4 million cancer cases, found that men are more likely than women to be diagnosed with cancer after the disease has already spread to the lymph nodes or other organs.

The researchers compared cancers detected at an early stage with cancers that had already spread.

Several possible explanations

The researchers point to several possible reasons for the difference. One is that women generally visit the doctor more often than men, which may lead to symptoms being detected earlier.

Cancer screening may also play a role in certain types of cancer.

At the same time, the researchers believe that, in some cases, men and women may be assessed differently within the healthcare system.

Why more men die from cancer

The study found that men are more likely to be diagnosed with advanced cancers of the tongue, thyroid gland, salivary glands, stomach, and melanoma.

Only a small number of cancer types showed men to be less likely than women to receive a late diagnosis.

The researchers believe the findings may help explain why more men than women die from cancer.

When the disease is detected at a later stage, it is often more difficult to treat.

The researchers therefore emphasize that regular medical check-ups can help detect cancer earlier.

Certain contraceptives linked to increased risk of brain tumors in new study

Certain contraceptives linked to increased risk of brain tumors in new study

Danish researchers analyzed data from women aged 15 to 59 over a 25-year period.

The aim was to investigate whether the use of hormonal contraception could be linked to the development of meningiomas, the most common type of brain tumor in adults, according to The Sun.

The study included 1,473 women diagnosed with meningiomas and 14,717 women without the condition.

Information on contraceptive use was obtained from the Danish National Prescription Registry, and the findings were published in JAMA Network Open.

The risk is small

The researchers emphasized that more studies are needed before the observed association can be explained.

Other experts also pointed out that the overall risk is very low and that the study does not provide sufficient evidence to justify changes to current clinical practice.

They also stressed that contraception remains an important tool for preventing unintended pregnancies and that decisions about contraceptive methods should be made in consultation with a doctor.

Some types showed a higher risk

The study found that some progestin-only contraceptives were associated with a higher risk of meningiomas than in women who did not use hormonal contraception.

The highest risk was observed among women who received medroxyprogesterone acetate injections.

An association was also found for certain types of combined oral contraceptive pills, progestin-only pills, and hormonal intrauterine devices (IUDs).

The risk was highest among women who were using the contraceptives at the time of the study or had used them within the previous year.

For most contraceptive products, the increased risk disappeared within five years after treatment had been discontinued.

Dietitians warn against combining coffee and grapefruit

Dietitians warn against combining coffee and grapefruit

Many people start their day with a cup of coffee. While that is not necessarily a problem, what you eat alongside it can make a difference.

According to several dietitians interviewed by Parade, food can influence how the body absorbs caffeine.

For example, eating a meal can slow the absorption of caffeine, which may help reduce feelings of jitteriness and discomfort.

Some people should be especially cautious

Experts also point out that certain foods can affect how the body breaks down both caffeine and specific types of medication.

As a result, caffeine may remain active in the body for longer than usual. At the same time, some medications may also stay in the body for an extended period.

This includes certain cholesterol-lowering drugs, blood pressure medications, and medicines used to treat heart rhythm disorders.

People taking medication should therefore consult their doctor or pharmacist if they are unsure.

Coffee can also cause heartburn in some people. The risk may increase if coffee is consumed together with acidic foods, particularly on an empty stomach.

This fruit may prolong the effects of caffeine

The fruit experts are warning about is grapefruit.

According to the dietitians cited, both grapefruit and grapefruit juice may cause the body to take longer to break down caffeine.

For some people, this may lead to jitteriness, heart palpitations, or sleep disturbances.

However, research published in the British Journal of Clinical Pharmacology has not reached a definitive conclusion, and the effect does not appear to be the same for everyone.

If you are particularly sensitive to caffeine or take medication known to interact with grapefruit, it may be a good idea to avoid combining the two.

Early warning signs in your stomach that could signal cancer

Early warning signs in your stomach that could signal cancer

Stomach cancer can initially cause symptoms that are easy to mistake for common digestive problems. A gastroenterologist is urging people to pay attention to warning signs that keep coming back, reports LADbible.

Common symptoms can hide a serious illness

According to Dr. Yoga Andredi, many people believe stomach cancer only causes severe pain. He explains that the disease often begins with much more subtle symptoms.

An aggressive form of cancer

The doctor describes stomach cancer as an aggressive disease, adding that an early diagnosis can improve the chances of successful treatment.

A burning sensation in the stomach

Persistent burning or discomfort in the stomach may be an early warning sign, especially if the symptoms continue over a longer period.

When indigestion does not improve

If indigestion or acid reflux does not get better despite using common remedies, the symptoms should be investigated further, according to the doctor.

Feeling full very quickly

Another possible sign is becoming full after eating only a small amount of food, even when you would normally have a bigger appetite.

The stomach may hold less food

Dr. Andredi explains that a growing tumour can reduce the stomach’s capacity and affect how it functions.

Unexplained weight loss

Losing weight without changing your diet or exercise routine can be one of the early symptoms of stomach cancer.

Loss of appetite

A reduced appetite is one reason why people with stomach cancer may begin to lose weight, the doctor says.

Persistent nausea

Ongoing nausea or a constant feeling that you may vomit should not be ignored if it continues.

Vomiting may occur

As the disease progresses, the tumour can affect how the stomach fills and empties, which may lead to episodes of vomiting.

Black stools

Bleeding in the stomach can result in black stools because the blood changes as it passes through the digestive system.

Blood loss may lead to anaemia

According to the doctor, bleeding from the stomach can cause a low red blood cell count due to blood loss, making it an important warning sign.

New research: Peppermint oil may lower blood pressure

New research: Peppermint oil may lower blood pressure

High blood pressure is one of the leading causes of cardiovascular disease worldwide, according to SciTechDaily.

Many people take medication to manage the condition, but treatment can be expensive and may cause side effects.

Researchers from the University of Central Lancashire have therefore investigated whether peppermint oil could serve as an alternative.

Peppermint contains natural compounds such as menthol and flavonoids, which may affect the body.

A 20-day trial

The study, published in PLOS One, involved 40 adults aged between 18 and 65 with mildly elevated blood pressure. The participants were divided into two groups.

One group received peppermint oil daily for 20 days, while the other group received a placebo product without active ingredients.

During the trial, researchers monitored blood pressure, heart rate, sleep, and overall well-being.

Clear difference

The results showed that participants who received peppermint oil lowered their systolic blood pressure by an average of 8.5 mmHg.

Systolic blood pressure is the top number in a blood pressure reading.

According to the researchers, only minor changes were observed in the placebo group.

They therefore believe peppermint oil could become a simple and affordable way to help people with mildly elevated blood pressure.

However, the researchers stress that more studies are needed before the treatment can be widely recommended.

PFAS are everywhere – here’s how to avoid them in daily life

PFAS are everywhere – here’s how to avoid them in daily life

PFAS are chemicals found in many everyday products.

The French Ministry of Health is therefore recommending several simple changes at home, according to Libération.

Among the recommendations is avoiding old plastic containers and nonstick frying pans.

Instead, the authorities suggest using glass, stainless steel, and cast iron. They also advise against heating food in plastic containers.

In addition, people are encouraged to use fewer water- and grease-resistant products, such as waterproofing sprays and certain types of packaging.

Air and food

The Ministry of Health also recommends airing out homes for ten minutes every day. Floors should be cleaned with simple products such as soap or vinegar.

When it comes to food, the advice is to eat a varied diet and preferably choose seasonal and homemade foods. Organic products are also mentioned as a possible option.

Although there is concern about PFAS in drinking water, the authorities still recommend tap water over bottled water.

This is because tap water is continuously monitored.

Particularly vulnerable groups

According to the Ministry of Health, some groups are more vulnerable than others. This includes pregnant women, infants, and employees at companies that work with PFAS.

PFAS are often referred to as “forever chemicals” because they break down very slowly in nature.

According to the authorities, the substances may be linked to elevated cholesterol, fertility problems, and certain types of cancer.

New drug may reduce risk of another stroke by 26 percent

New drug may reduce risk of another stroke by 26 percent

A stroke is a serious condition that affects many people every year.

According to the U.S. health authorities at the CDC, nearly one in four strokes occurs in people who have already experienced the condition once before.

Research published in the journal Stroke also shows that a recurrent stroke often carries a greater risk of severe complications or death than the first.

As a result, researchers are working to find better treatments for patients who have already been affected.

New method being tested

Today, many patients receive blood-thinning medication or cholesterol-lowering treatment after a stroke. The challenge is that these medications can increase the risk of bleeding.

According to Parade, researchers have now examined a blood protein called factor XI. People with low levels of this protein appear to have a lower risk of developing blood clots.

Researchers have therefore developed a drug called asundexian, which targets this protein in a new way.

Results offer hope

A large international study published in The New England Journal of Medicine, involving more than 12,000 participants, showed that asundexian reduced the risk of new strokes by 26 percent compared with a placebo.

The drug is now being evaluated by the U.S. Food and Drug Administration (FDA). If approved, it could reach the market in early 2027.

Experts stress, however, that a healthy diet, exercise, good sleep, and reduced tobacco use remain important in preventing strokes.

Passion fruit gains attention among nutrition experts

Many people try to eat healthier before summer, but staying full throughout the day can be difficult. Cravings and unnecessary snacking often become the biggest obstacle, especially during busy afternoons and evenings.

According to nutrition experts and reports highlighted by the Hungarian outlet Kiskegyed, one tropical fruit is now gaining attention for its potential health benefits and ability to support healthy eating habits.

More than exotic

While citrus fruits like lemons and grapefruit are often linked to weight loss, experts say other fruits may offer similar advantages.

Passion fruit is now being highlighted for its combination of low calories and high fibre content. Nutrition specialists explain that fibre helps slow digestion, which can increase feelings of fullness and reduce the urge to snack between meals, reports Newsner.

Because of this, the fruit is becoming increasingly popular among people trying to improve their diet before summer.

Why experts are interested

Health experts also point to the antioxidants and plant compounds naturally found in passion fruit. Some studies suggest these nutrients may help support metabolism and contribute to more stable blood sugar levels throughout the day.

Researchers stress that no single food can remove belly fat on its own. However, they say passion fruit can be a useful addition to a balanced lifestyle that includes regular exercise and healthy eating habits.

The fruit can easily be added to yoghurt, smoothies or eaten fresh as a simple snack.
