Researchers: These supplements may be necessary for older adults

10. June, 2026

Dietary supplements are often marketed as an easy way to gain more energy, strengthen the immune system, and live longer.

However, for most people, they provide only limited benefits if the body is already receiving the nutrients it needs.

For older adults, the situation is somewhat different. As people age, their appetite may decline, and illness or medication can make it more difficult for the body to absorb important vitamins and minerals.

Not for everyone

According to researchers writing for The Conversation, supplements should only be used when there is a genuine deficiency.

This applies in particular to vitamin B12, vitamin D, and folate, which older adults are more likely to lack than younger people.

At the same time, the researchers emphasize that several studies have found no evidence that multivitamins improve health or increase longevity in otherwise healthy individuals.

Can cause problems

Dietary supplements are not entirely risk-free. Excessive amounts of certain vitamins can be harmful, and some products may interfere with the effectiveness of medications.

For this reason, it is recommended that people first determine whether they actually have a deficiency before starting any new supplements.

Too little protein

While many people focus on vitamins and minerals, the researchers point to something else that is often overlooked.

Many older adults do not get enough protein through their diet. This can lead to a loss of muscle mass, reduced strength, and a greater risk of falls.

The researchers therefore conclude that the most important step for many older adults is not necessarily taking more pills.

Instead, it may be ensuring adequate protein intake and maintaining a varied, balanced diet. Supplements can be useful, but only when they address a documented nutritional need.

These foods can support your vision in everyday life

Many hours spent in front of screens, dry air, and advancing age can place more strain on the eyes than most people realize.

According to Apetit, a varied diet that includes specific nutrients may help support eye function and protect against common age-related changes.

Antioxidants are important for the eyes

The retina and the macula rely on nutrients such as lutein, zeaxanthin, vitamins A, C, and E, zinc, and omega-3 fatty acids.

These compounds help protect the eyes from oxidative stress and act as a natural defense against blue light.

Diet can help protect vision

A well-balanced diet cannot eliminate the need for glasses, but it may help reduce the risk of cataracts and support retinal health throughout life.

Carrots

Carrots are rich in beta-carotene, which the body converts into vitamin A as needed.

Vitamin A is essential for vision in low-light conditions and helps keep the surface of the eye healthy and well-moisturized.

Vitamin A has several functions in the eye

A deficiency in vitamin A may be linked to dry eyes and a reduced ability to see in the dark.

This is why the vitamin plays a crucial role in maintaining normal eye function.

Fat

When carrots are eaten with a small amount of fat, the body can absorb their beneficial nutrients more effectively.

Carrots cannot correct vision problems

Although carrots are highly nutritious, they cannot cure nearsightedness or farsightedness.

Sweet potatoes

One medium-sized sweet potato can provide the recommended daily amount of vitamin A.

In addition, it supplies dietary fiber and potassium.

Dark green vegetables

Spinach, kale, and other dark leafy greens contain high levels of lutein and zeaxanthin, which accumulate in the part of the eye responsible for the sharpest vision.

Lutein and zeaxanthin

These plant compounds help filter blue light and may reduce the risk of cataracts while supporting retinal health.

Egg yolks

Egg yolks contain less lutein than spinach, but the body can absorb the nutrient efficiently thanks to the fat content of the egg.

Eggs

In addition to lutein, eggs also provide vitamin D and protein, making them a valuable part of a balanced diet.

Pistachios stand out among nuts

Pistachios are highlighted as the only nut that contains lutein. They also provide antioxidants and healthy fats.

Almonds and sunflower seeds contain vitamin E and zinc

These nutrients help protect eye cells from damage caused by free radicals.

Fish

Salmon, mackerel, and sardines are excellent sources of omega-3 fatty acids, which are important structural components of the retina.

Omega-3 may help with dry eyes

These fatty acids support the function of the tear glands and may benefit people who experience dry eyes due to prolonged screen use.

Vitamin C supports blood vessels in the eyes

Oranges, lemons, blueberries, and blackcurrants contain vitamin C, which helps protect the small blood vessels in the eyes and supports collagen production.

Berries

Berries are rich in antioxidants that may help protect the eye’s lens from clouding.

Consistency is more important than quick fixes

Apetit emphasizes that the eyes benefit most from a varied diet maintained over time rather than short-term diets or supplements.

Potatoes, rice or pasta? Here is the healthiest choice

Potatoes, rice or pasta? Here is the healthiest choice

Rice, pasta and potatoes are known for being rich in carbohydrates, which provide the body with energy. As a result, they are a staple part of many meals.

At the same time, they are often criticized for being less filling or for causing blood sugar levels to rise quickly.

However, according to the German Nutrition Society (DGE), as cited by UTOPIA, the impact largely depends on which type you choose.

Whole-grain products contain more dietary fibre and nutrients than their more processed counterparts, providing a longer-lasting feeling of fullness.

Major differences

Rice is one of the world’s most important staple foods, but its production requires large amounts of water.

According to UTOPIA, citing the Sustainable Rice Platform, rice cultivation uses a significant share of the world’s freshwater resources.

In addition, rice often contains small amounts of arsenic.

Brown rice contains more nutrients than white rice, while parboiled rice retains a greater proportion of its nutritional value.

Pasta primarily provides energy. Whole-grain pasta contains more fibre, vitamins and minerals than regular pasta and is therefore considered the best option within its category.

The clear winner

When the three foods are compared directly, information from the Bayerische Landesanstalt für Landwirtschaft points to one clear favourite.

Potatoes are relatively low in calories, provide a strong feeling of fullness, and contain nutrients such as vitamin C, B vitamins, potassium and magnesium. They also have a lower climate footprint than both rice and pasta.

As a result, potatoes are considered the healthiest choice of the three when prepared without deep-frying. They are followed by brown rice and whole-grain pasta.

These drinks may keep the body hydrated longer than water

These drinks may keep the body hydrated longer than water

For most people, water is the obvious choice when thirst strikes. It is healthy, calorie-free, and easy for the body to process, according to Kölner Stadt-Anzeiger.

However, researchers at the University of St Andrews in Scotland investigated whether other beverages remain in the body longer than water. Their study was published in the American Journal of Clinical Nutrition.

In the experiment, 72 healthy men drank one litre of various beverages. Researchers then monitored their urine output over a four-hour period to determine how much fluid the body retained.

Sugar does not always help

The researchers also examined drinks containing sugar, coffee, and alcohol. A high sugar content does not automatically make a beverage better for hydration.

In fact, excessive amounts of sugar can temporarily draw fluid out of the body.

Coffee performed similarly to water when consumed in moderate amounts, equivalent to around two to three cups of coffee.

Alcohol, on the other hand, has a diuretic effect. The more alcohol a drink contains, the more fluid the body loses.

The best drinks

Skim milk was the most effective beverage for retaining fluid in the body. It was followed by oral rehydration solutions, whole milk, and orange juice.

One explanation is that milk contains protein, fat, and sodium. These components slow the rate at which fluid leaves the stomach, allowing it to remain in the body for longer.

Water remains an excellent everyday choice. However, during periods of extreme heat, intense exercise, or situations where drinking frequently is not possible, skim milk may help the body retain fluid more effectively, according to the study.

More time sitting may increase pregnancy complication risk, study finds

Health problems such as gestational diabetes, high blood pressure during pregnancy, and preterm birth have become more common in recent decades, according to HealthDay. As a result, researchers are looking for ways to reduce these risks.

A new study published in the scientific journal JAMA examined whether daily activity habits could play a role.

Activity levels among pregnant women

The study included 470 pregnant women from several U.S. states. All participants were in the early stages of pregnancy and wore an activity tracker for one week.

The device recorded how much the women moved and how long they remained sedentary throughout the day.

Researchers then compared the participants’ activity levels with the occurrence of complications later in pregnancy.

Surprising findings

The study found that women who spent more than 10 hours a day sitting had a significantly higher risk of complications than those who spent around seven hours sitting daily.

Among the women with the most sedentary time, approximately two in five experienced complications. Among women who spent less time sitting, the figure was about one in five.

The researchers therefore suggest that the solution is not necessarily intense exercise. Instead, simply standing up more often and incorporating short periods of movement throughout the day may be beneficial.

According to the researchers, reducing time spent sitting could help lower the risk of complications during pregnancy.

Future dementia test may be performed by the eye doctor

Dementia affects a growing number of people, and diseases such as Alzheimer’s can develop for many years before the first symptoms appear, according to Der Standard.

As a result, researchers around the world are working to find methods for earlier diagnosis.

At the same time, developing new medical products remains challenging.

The healthcare sector places high demands on documentation, and new solutions must undergo extensive approval processes before they can be put into use.

New technology

The Austrian start-up Thyra Imaging is working with a technology that was originally developed for astronomical telescopes.

In astronomy, it is used to create sharp images of objects far out in space.

Researchers have adapted the technology so that it can capture highly detailed images of the retina instead.

The images are then analyzed using artificial intelligence to identify small changes in the tissue.

The company is now working to make the equipment more compact so that it can be used in research centers and, later, in healthcare settings.

A window to the brain

Research shows that certain brain diseases can also be detected in the retina. For this reason, researchers describe the eye as a potential window to the brain.

The goal of the project is to develop a scan that can detect cellular changes associated with dementia and other neurological diseases in just a few seconds.

If successful, the technology could make it possible to identify these diseases many years before the first symptoms appear.

17,000 people reveal their toilet habits – many suffer in silence

Constipation is a common problem in many countries, yet the topic remains surrounded by stigma.

A major international survey conducted by Movicol among nearly 17,000 adults reveals how widespread the issue is and how it affects everyday life.

Constipation is a global problem

Nearly 17,000 adults from nine countries took part in the survey about constipation and their experiences with the condition.

Nine countries participated in the survey

Participants came from Australia, Denmark, France, Germany, Italy, Norway, Spain, Sweden, and the United Kingdom.

Many people experience constipation

The results show that a significant number of people have experienced constipation during the past year.

The problem is more widespread than many think

The survey suggests that constipation is a common issue across all the countries included in the research.

Stigma makes it difficult to talk about

Although many people experience constipation, there is still considerable reluctance to discuss bowel function and bowel movements.

Stigmatization affects people

Stigma surrounding bowel movements makes it harder for individuals to acknowledge symptoms and seek help.

Many suffer in silence

Many people deal with the problem on their own without being aware of available treatment options.

Lack of treatment can have consequences

The report highlights that constipation can have long-term consequences if left untreated.

Constipation affects more than the stomach

According to the research, the condition can impact several aspects of daily life and not just digestion.

Working life is affected

Constipation can reduce productivity in the workplace.

Some people miss work

In the United Kingdom, 19 percent reported being absent from work several times a year or more often because of constipation.

Energy levels can decline

People experiencing constipation report lower energy levels, increased stress, poorer concentration, and less positive social behavior.

Great relief after a bowel movement

The survey describes the phenomenon known as “poophoria,” referring to the feeling of satisfaction and relief following a successful bowel movement.

How constipation develops

When stool moves slowly through the intestines, it loses water and becomes harder and more difficult to pass.

Early action is important

The report emphasizes the importance of recognizing symptoms early, as the condition can become more difficult to manage over time.

Treatment can help

The report aims to raise awareness that constipation and hard stools can be treated and that it is worthwhile to take action at an early stage.

Which protein source is best for muscle health? Study compares animal and plant proteins

Which protein source is best for muscle health? Study compares animal and plant proteins

In the U.S. Dietary Guidelines, foods such as meat, eggs, beans, and nuts are often compared nutritionally based on standard serving sizes.

However, researchers from Purdue University point out in their study published in Nutrients that these foods contain different amounts of protein and essential amino acids.

Essential amino acids are nutrients that the body cannot produce on its own and that play an important role in muscle health, among other functions, according to SciTechDaily.

Trial involving adults

The study included 55 healthy adults divided into a younger group and an older group.

During separate test meals, participants consumed either lean pork, eggs, black beans, or almonds.

Following the meals, researchers collected blood samples over a five-hour period to measure how many essential amino acids entered the bloodstream.

The researchers also examined whether age influenced the results.

A clear difference

The results showed that meals containing pork and eggs produced higher levels of essential amino acids in the blood than meals containing beans and almonds.

There was no significant difference between the younger and older participants.

However, the researchers emphasize that the study does not demonstrate whether different protein sources lead to greater muscle growth or better long-term health outcomes.

The findings therefore suggest that two equal-sized servings of protein do not necessarily provide the body with the same nutritional benefit.

Blood pressure medication may be linked to kidney damage

Many people with type 2 diabetes take medication to protect their kidneys and keep their blood pressure under control.

Several different drugs are often combined to reduce the risk of complications, according to HealthDay.

A new study presented at the European Renal Association Congress in Glasgow examined how different treatments affect patients with diabetic kidney disease.

More than 31,000 patients

Researchers analyzed health data from more than 31,000 adults with type 2 diabetes between 2016 and 2021.

All participants received two types of medication that are commonly used to protect kidney function.

Nearly four out of ten patients also received a third type of blood pressure medication known as DCCB.

This medication is often prescribed as an additional treatment when further blood pressure reduction is needed.

The researchers followed the patients for approximately three and a half years and compared their outcomes.

33 percent higher risk

The researchers believe the medication may affect blood flow in the kidneys in a way that increases strain on the organs. However, this has not yet been proven.

Patients who received DCCB alongside their other treatment had a 33 percent higher risk of developing serious kidney problems than patients who did not receive this class of medication.

The researchers emphasize that the study only shows an association and does not prove that the medication is the cause.

They therefore recommend further research before any changes are made to treatment guidelines.

More young adults are developing oral cancer – here’s how to protect yourself

Researchers do not yet know exactly why more people are developing oral cancer.

According to the Finnish Dental Society Apollonia, cited by the media outlet Iltalehti, the disease is now occurring more frequently than before.

Oral cancer primarily affects people over the age of 60, but international studies show that an increasing number of people under 45 are also being diagnosed with the disease, according to Iltalehti.

There is still limited knowledge about how products such as nicotine pouches and e-cigarettes may affect the risk.

Known risk factors

Tobacco and alcohol are among the most significant risk factors. The risk becomes even greater when the two are used together.

Diet may also play a role. According to Apollonia, high consumption of sugar, refined carbohydrates, and fatty foods may increase the risk.

Poor oral hygiene and severe gum disease may also contribute.

Important to take action

Oral cancer can be difficult to detect in its early stages. It is often found along the edge of the tongue and may spread to the lymph nodes in the neck.

Changes in the mouth that do not disappear after two to three weeks should be examined.

The same applies to pain on one side of the mouth or tongue.

When the disease is detected at a later stage, treatment becomes more difficult. According to Apollonia, between 30 and 40 percent of oral cancer patients die from the disease.
