Rowan – healthy berries and magic powers

Published October 6, 2024 – By Editorial staff
Rowanberries are great for freezing or drying.

The rowan berry is extremely rich in vitamin C and antioxidants, but it has also long been a revered protective tree, described as magical in ancient folklore and Norse mythology.

The rowan is a common tree in Sweden that many people today may pass by without giving it much thought, but in the past the rowan had a very special place in the Nordic landscape and was thought to protect against evil forces, for example. The berries that fall in autumn are also rich in nutrients and can be frozen or dried. There is also the question of whether there is any truth in the old saying that the tree can predict what sort of winter there will be.

A year-round tree

The rowan grows in many parts of Europe, North America and Asia. It is often considered to be a typical autumn tree, but it is a tree that is beautiful all through the whole year and makes a good garden tree. It is easy to grow, often healthy and fast-growing, but does not live more than 50 to 60 years. There are several different types of rowan, for example there are yellow-fruited trees and also a variety called the sweet rowan.

Three berries a day

Rowan berries may not have been considered very edible in the past, but they have had a renaissance in recent years. The berries are in fact small apple-like fruits and often have a rather bitter and sour taste. After the first frost, the berries should be more palatable.

The berries are extremely rich in vitamin C and just three berries a day should provide the daily requirement. It is worth noting that rowan berries also contain the sugar alcohol sorbitol, which is often used as a sweetener in foods, and eating large amounts can have a laxative effect. For this reason, the berries may be good for constipation.

They also contain antioxidants in the form of polyphenols and some beta-carotene. The berries also contain small amounts of several other vitamins and minerals. Like lingonberries and cranberries, rowan berries are also thought to prevent urinary tract infections. In the past, they were also used to treat scurvy, joint pain and kidney stones.

Freeze or dry

Rowan berries can be frozen, so you can pick them before the first frost and still get the milder flavour. It is also common to dry rowan berries and then use them in a bowl of yoghurt or porridge. Dried rowan berries can also be ground into a powder.

Alternatively, the berries can be used to make jam, marmalade or jelly. The berries usually go well with apples. Similar to lingonberries, rowan berries contain benzoic acid, which is a natural preservative. Rowan berries can be used in bread. Dried rowan berries can also be used to brew tea, which can also be made with young rowan leaves.

Think of the birds

After the frost, when the berries become milder, rowan berries also become food for several species of birds and are an important source of food for them during the winter. Even though rowan trees can grow very tall and we can seldom reach all the berries, it can be a good idea to leave berries for the birds. If you like, you can also freeze them and save them for the bird feeders in late winter.

Magic powers

Rowan (Swedish: rönn) is an Old Norse name for 'red' and the tree has a special place in the Nordic landscape. In the northern parts of Sweden it was a common guardian tree, a tree that served as a kind of link to the spirit world and could also be seen as a living guardian of the farm. Especially on farms in the forest, where the so-called forest Finns lived, the rowan was often the guardian tree, as it was an important symbol for the migrating Finns: in the Finnish national epic, the Kalevala, it is said that "the holy rowan is on the farm". In Finland it is still common to have rowan trees on the farm.

In the Skáldskaparmál, part of Snorri's Edda, the Aesir Thor saves himself from a stream with the help of a rowan tree, and according to folklore the rowan tree was then given power by Thor in gratitude for its help. The rowan tree was thought to protect against lightning, witchcraft and the so-called Lady of the Woods. The flying rowan, i.e. a rowan that has sprouted from another tree and grown as a separate tree, was considered particularly magical and protective.

One of the most famous sayings about the rowan is that it can predict what winter will bring. If the rowan has many berries, there will be a cold winter to come. However, Ulf Sperens, a former researcher at Umeå University, says this is nothing but a myth.

– The rowan cannot predict the future, quite the opposite, Sperens told country life magazine Land.

Study shows rising life expectancy but more young people are dying

Published today 12:48 pm – By Editorial staff

Global mortality is declining, but not among all age groups. Researchers are now warning that the world faces a growing crisis – namely an increasing number of deaths among adolescents and young adults.

Today, people live an average of 20 years longer than in the 1950s, and age-standardized mortality is 67 percent lower – according to the annual Global Burden of Disease study, which has analyzed data from 204 countries and territories between 1990 and 2023.

In the study, published in The Lancet, thousands of researchers have analyzed data and produced estimates for 375 diseases and injuries as well as 88 risk factors by age and sex – globally, regionally, and nationally for all countries.

It shows that half of the world's diseases are preventable and are driven by various risks such as high blood pressure, air pollution, smoking, and obesity.

Non-communicable diseases such as heart disease, stroke, and diabetes account for nearly two-thirds of the world's total mortality and morbidity.

Suicide and drugs among young people

Despite the decline in global age-standardized mortality, researchers are sounding the alarm about a concerning trend: mortality among young adults is increasing in several parts of the world.

Among adolescents and young adults, the largest increase in deaths was recorded among people aged 20 to 39 in high-income countries in North America between 2011 and 2023, where suicide, drugs, and alcohol were the main causes.

During the same period, deaths also increased in the 5-19 age group in Eastern Europe, high-income countries in North America, and the Caribbean.

The evidence presented in the Global Burden of Disease study is a wake-up call, urging government and health care leaders to respond swiftly and strategically to the disturbing trends that are reshaping public health needs, says Christopher Murray, director of the Institute for Health Metrics and Evaluation at the University of Washington.

In sub-Saharan Africa, more young people are also dying, but there infectious diseases and accidents are claiming young lives.

Mental illness increasing

Furthermore, mental illness continues to increase globally – with anxiety syndromes having increased by 63 percent and depression by 26 percent since 1990.

Geographic differences remain significant. Life expectancy varies from 83 years in high-income countries to 62 years in sub-Saharan Africa. Today, the global average life expectancy is 76 years for women and 71.5 years for men.

It’s never too late – older adults can regain their health

Published November 22, 2025 – By Editorial staff

Older adults can regain full health and quality of life even after serious health problems, shows a new study. Nearly one in four people over 60 with poor well-being had completely recovered after three years.

In the study, researchers from the University of Toronto examined data from the Canadian Longitudinal Study on Aging (CLSA), a long-term study that collects data on aging in Canada. First, they examined people who had reduced health and quality of life and were 60 years or older during the years 2011–2015.

They then followed up with these participants three years later, during 2015–2018, to see how their health had changed and, above all, whether it had improved. A total of 8,332 people participated in the study.

Participants' well-being was measured through the absence of serious physical, cognitive or emotional problems as well as high self-reported physical and mental health, happiness and life satisfaction. Furthermore, researchers also examined whether participants had a healthy body weight, regular physical activity, good sleep, avoided smoking and whether they participated in social activities.

The results, which were published in PLOS One, show that nearly one in four people over 60 who reported poor well-being at the start of the study had regained optimal health and quality of life after three years. Those who already had strong psychological and emotional well-being at the beginning were more than five times more likely to regain optimal health.

It's incredibly encouraging to see that, with the right supports and lifestyle, many older adults can reclaim full health, happiness, and independence - even after serious health challenges, says lead author Mabel Ho to Medicalxpress.

Often, studies about older adults focus on health deterioration and functional decline, but this study does the opposite – it shows that it is possible for older adults to regain good health and that it is not uncommon either.

We want this study to reshape how society views aging. With the right environment, resources, and supports, older adults don't just survive after struggling with health or well-being issues -  they thrive, says Ho.

Wireless earbuds may cause thyroid nodules

Published November 11, 2025 – By Editorial staff

Prolonged use of wireless earbuds can cause thyroid nodules, according to various studies. Furthermore, research shows that these types of earbuds expose users to varying degrees of magnetic fields.

Abnormal growths in the thyroid gland typically manifest as localized swellings in the thyroid tissue. Most thyroid nodules are benign, asymptomatic and require no treatment, but some can be malignant – something that has increased dramatically in the population over the past 15 years according to a study published earlier this year.

A study from 2024 showed that prolonged daily use of wireless earbuds that transmit 2.4 GHz Bluetooth microwaves is strongly linked to an increased risk of thyroid nodules, writes the Swedish Radiation Protection Foundation. This is explained by the fact that the thyroid gland, which is very sensitive to radiation, is one of the most exposed organs when using such earbuds as well as a mobile phone. The study also showed that sensitivity to developing thyroid nodules increased with advancing age.

"Our study highlighted a significant impact relationship between prolonged Bluetooth headset use and increased thyroid nodule risk, emphasizing the importance of considering health impacts in the use of modern technology, especially for devices like Bluetooth headsets that are frequently used daily", the researchers conclude.

Magnetic fields

Wireless earbuds emit radiation, but studies also show that they emit magnetic fields. In a study published in 2023, researchers examined six models of in-ear earbuds. These provided exposure to static magnetic fields from 20 mT at the surface to tens of μT in the inner ear. The researchers note that more research is needed on the combination of exposure to elevated magnetic fields and microwaves – recommending the use of air tube headphones.

Apple's wireless AirPods, for example, "communicate with one another using a magnetic induction field, a variable magnetic field sends through your brain to communicate with the other", explained Dr. Joel Moskowitz in the Daily Mail, who is one of the leading experts in the field of health risks from electromagnetic radiation and a member of the International Commission on the Biological Effects of Electromagnetic Fields (ICBE-EMF). He noted that research on the health effects of this exposure is completely lacking.

Probably carcinogenic

Microwave radiation is something that research has shown can damage cellular DNA, cause oxidative stress and damage brain cells and function, which can have effects such as headaches, impaired memory, cognitive ability and sleep – and it is precisely this type of radiation found in wireless earbuds, something the Swedish Radiation Protection Foundation has written about.

The World Health Organization's International Agency for Research on Cancer (IARC) has classified microwave radiation as possibly carcinogenic, class 2B. Many researchers today believe that the radiation should be considered carcinogenic.

PFAS during pregnancy alters child’s brain

Published October 16, 2025 – By Editorial staff
Research shows for the first time how PFAS in pregnant women can alter children's brain structure several years later.

For the first time, researchers can demonstrate how PFAS in pregnant women affects their children's brains long-term. The Finnish-Swedish study shows that structural changes can be observed in children when they are five years old.

The study, which has been published in Lancet Planetary Health, is a collaboration between Örebro University (Sweden), Åbo University (Finland), and Turku University Hospital (Finland), and is part of the EU project INITIALISE (Inflammation in human early life: targeting impacts on life-course health).

PFAS consists of a range of chemicals that are difficult to break down and have been found not only in nature, but also in humans and animals. Some of these chemicals can be harmful to health. Research has shown that PFAS can affect the immune system and is also suspected to have effects on metabolism, hormonal balance, and brain development.

Because PFAS remains in the body, it can also pass from a pregnant woman to the placenta, which means the child can be exposed. Previous studies have, for example, indicated that if pregnant women have PFAS in their blood, there is a greater risk that the child will become overweight later in life.

Affected brain structure

This study is the first of its kind to examine the entire brain simultaneously in a brain scanner in children in relation to PFAS exposure during pregnancy – several years after birth.

The study was conducted using the FinnBrain Birth Cohort Study, which was established at Åbo University (Finland) in 2011. It is a long-term study that follows thousands of children and mothers from pregnancy onward. Some of the children underwent brain scans, and these results have been compared with the levels of PFAS measured in the mothers during pregnancy.

The results show that there is a connection between higher levels of PFAS in pregnant women and changes in both the brain's structure and in the connections between different brain regions in their children. These changes were observed five years later.

This is the first time researchers have been able to describe how PFAS in pregnant women can be linked to changes in their children's brains several years later.

This is an important piece of the puzzle in understanding how chemicals can affect children's development. Step by step, we are gaining more knowledge about how different environmental factors interact and can contribute to health problems, says Tuulia Hyötyläinen, professor at Örebro University, in a press release.

Exposure to PFAS during pregnancy and also during early development in the child is considered particularly sensitive, the researchers say, because the brain and other organs grow rapidly and are formed during that time. More research is now needed on how PFAS affects brain function.

Overall, the research shows that PFAS can affect brain development even at low levels. More research is needed on how chemicals affect cognition and brain function in children, what the causes are, and what it leads to, says Hyötyläinen.

Researchers' tips to avoid PFAS while awaiting stronger legislation:

  1. Eat fish, but avoid fish from lakes contaminated with PFAS. For more information about contamination levels, contact your local municipality. Also reduce consumption of takeaway food and microwaveable meals in grease- and water-repellent paper packaging.
  2. Avoid cooking with non-stick products.
    Avoid makeup, soap and beauty products containing PFAS. In ingredient lists, look out for: PTFE, polytetrafluoroethylene, "...perfluoro..." or "...polyfluoro...".
  3. PFAS is often found in water-repellent functional clothing. Since most PFAS is released during production, buying second-hand clothes can help reduce these chemicals in nature.
