This black berry may not be as tasty as blueberries, but it is just as healthy. With high levels of fiber, antioxidants, and vitamin C, the crowberry is a super berry in all its glory that is both widely eaten and used in folk medicine.

The crowberry is a black berry similar to the blueberry, but smaller, harder and with larger seeds. Its leaves are coniferous, making it easy to recognize and not to be confused with other plants. They are found in most parts of the country and are almost as common as blueberries, but unlike blueberries, crowberries do not stain hands and clothing. The berry can be picked from July until the first snow falls. Overripe berries can be picked in the spring.

Not food for crows

According to archaeologists, crowberries were one of the earliest plants to appear after the Ice Age. The oldest traces found in fecal remains are 10,000 years old and were found in Balltorp outside Gothenburg. In Sweden, however, there is a difference between where they have been eaten most. In the northern parts of the country, with a border at Gävle and Falun, crowberries are said to have been eaten a lot. But not so much in the southern parts. The reason may be that there are two different types of crowberries, a northern and a southern variety. The northern berries are said to be tastier, but it is difficult to tell them apart with the naked eye.

The name does not imply that it is a berry that the crow eats, but rather that it is something that the bear likes to eat along with blueberries. Historically, however, the crow was considered unlucky, and darker berries were often considered inedible, which may be the reason for the name “crowberry”. The crow also appears in the name of the berry in Swedish, kråkbär, Finnish variksenmarja, and German krähenbeere.

Although the crow may not eat the berries, other birds do. Because the berries do not spoil during the winter, they are an important food source for returning migratory birds. Smaller animals such as stoats also like to eat them.

The berries have been very important in Sami culture, where they were eaten in soups or with hot reindeer fat. It was also common to mix crowberries with milk or whey, according to Finnish national broadcaster Yle. According to a book on the Finnish Scots written by the late ethnographer Samuli Paulaharju, crowberries were the only berries that the Sami people gathered for the winter.

They were also widely eaten in Finland and Norway. In Norway, they may also be called “silence berries” or “comfort berries”, probably because they were a source of comfort when there was nothing else available for a dry throat while hiking in the forest, according to the Norwegian Helsemagasinet. The berries were also often used to make ink or paint for clothing or fishing nets.

Folk medicine

Crowberries have been used as a diuretic and laxative in folk medicine, where they have been called “pee berries” in Norway. Children are said to have been warned not to eat them in the evening because of the risk of bedwetting. They were also used to treat scurvy and mouth ulcers, which could be treated by gargling decoctions of the berries. According to Skogsskafferiet, a tea made from unripe green berries was used to treat kidney stones.

They have also been used to treat headaches, fever, and fatigue.

Health benefits

Along with blueberries, crowberries contain the highest levels of anthocyanin, an antioxidant and the substance that gives the berries their dark color. A 2008 Japanese study identified thirteen different anthocyanins in crowberries. Researchers analyzed the total anthocyanin content of crowberries, blueberries, and eight other common berries and found that crowberries had the highest levels.

They also contain flavonoids, which also act as antioxidants. Antioxidants can, for example, protect against oxidative stress caused by free radicals.

According to a Finnish study, crowberries grown in areas prone to early frost have higher levels of anthocyanins. They also contain more vitamin C than lingonberries.

Crowberries are also high in fiber, more than most imported fruits. The berries are also said to have anti-inflammatory and antibacterial properties.

Crowberry Uses

Crowberries can taste a bit rough, bitter and sour, but can be eaten fresh in the forest, they are perfect if you need some extra energy on a hike. However, they should taste better when pickled or juiced. They should also be good in jams or juices with other berries, such as currants. The leaves can be used to make tea. If you want to preserve the benefits of the berries a little longer, you can make unheated juice, as Anu Tossavainen does. She makes the juice without boiling it and sweetening it with honey instead of sugar.

– You can’t ruin your day if you start it with a glass of crowberry juice, she says, according to Yle.

You can also dry the berries and use them in porridge or a smoothie. You can also freeze the berries and use them later. Like lingonberries, you can also keep fresh berries in water in a jar in the fridge, where they will stay fresh longer.

Crowberry wine

It is said that crowberry wine has been made in Norway since the 12th century, during the reign of King Sverre Sigurdsson. It is said that German merchants imported so much wine to Norway that it became as cheap as beer, which also increased the number of drunks in the country. King Sverre found this problematic and told the Norwegians that it was the people’s duty to look after themselves and maintain public order, which the people listened to and the German merchants were no longer allowed to import wine. The king, who is said to have had a good knowledge of nature after growing up in the Faroe Islands, suggested that instead of importing German wine, they should make their own from crowberries. This is still the case today, and several Norwegian companies produce crowberry wine. Crowberries can also be used to flavor spirits.

Social media feeds young people junk food ads

A large majority of food advertisements that young people are exposed to promote unhealthy products such as fast food, snacks or sugar-sweetened drinks.

The majority of food advertising that young people encounter on social media promotes unhealthy products. This is according to a new study from Karolinska Institutet, where TikTok is identified as the platform with the highest exposure.

The survey is based on data from young people aged 13-16 who, over the course of a week, documented the advertising they saw in their social media feeds. They were given a choice of platform, with most choosing Tiktok or Instagram.

One third of all the ads young people were exposed to were for food or drink – and 70% of these were for unhealthy products such as fast food, snacks or sugar-sweetened drinks.

Exposure was highest on Tiktok, where participants could encounter up to 26 food-related ads per hour. On Instagram, the average was 13.

– In focus group interviews, participants said they were often tempted to make impulse purchases by the design of the ads. At the same time, several expressed a feeling of powerlessness in the face of the amount of advertising they encounter daily, said Sofia Spolander, researcher at the Department of Medicine, Huddinge in a press release.

Childhood obesity doubled

In the focus group, the young people also described how the advertising affected them and increased their cravings for unhealthy food, and that it was difficult to resist consumption.

Overweight among Swedish children aged 11–15 has more than doubled in the past 30 years, and obesity in this age group has quadrupled, according to the study. Young people are eating more unhealthy food than before, while consuming fewer fruits and vegetables. Unhealthy eating habits are one of the leading causes of poor health and premature death in Sweden.

The food environment influences our eating habits, and marketing is an important part of that environment. This study shows that the advertising young people encounter on social media goes against the dietary guidelines, says Spolander.

The study forms the basis of a new report from UNICEF Sweden and the Swedish Heart-Lung Foundation, which highlights how advertising for food and drink in social media affects the health of children and young people.

Young dog owners’ lifestyles negatively affect their dogs

Today, many people get a pet to fit into their passive lifestyle - rather than adapting to the animal's needs themselves.

Stressed and overweight dog owners feel their lifestyle also impacts their dogs, according to a new Novus survey commissioned by Arken Zoo’s veterinary services. The effect is especially noticeable among younger owners, who report that their own health issues spill over onto their pets.

The survey, conducted between March and April 2025, gathered responses from 1,046 Swedish pet owners aged 18 to 84 about their own and their dog’s well-being. The results reveal a strong link between owner lifestyle and pet health.

Half of pet owners consider themselves overweight, with two in ten not exercising at all. A quarter of dog owners say they walk their dog for an hour a day at most, while 18% say their dog is overweight. Veterinarian Per Bransell says the results are “alarming”, but not surprising.

– Today, many people get an animal to fit into the owner’s lifestyle instead of the owner adapting to the animal. Getting a pet is a commitment every day, not just on weekends and holidays, he said in a press release.

Young adults struggle so do their dogs

Among pet owners aged 18 to 34, 31% say they walk their dogs no more than an hour a day, and 23% report their pets are overweight.

Young owners also experience higher levels of stress: 42% see themselves as stressed, and 24% believe that stress affects their dogs. Staff at Hundstallet, a dog shelter that rehomes animals, say the survey aligns with what they see every day.

– People are increasingly unwell, and it has a direct impact on animals. We see a clear rise in dogs arriving in both poor physical and mental condition — often depressed, lacking proper veterinary care or stimulation, says Johnny Kroneld, Head of Communications & Fundraising at Hundstallet.

Use of obesity drugs surges in Finland

Sales of obesity medication have skyrocketed in Finland in just a few years.
1 minute read

The use of obesity medication increased significantly in Finland last year – many more Finns were treated for obesity compared to 2023. At the same time, opinions are divided on the effectiveness of the treatment.

A total of 75,000 Finns used medicines for weight loss or obesity treatment in 2024. This is an increase of 20% compared to 2023, according to the Social Insurance Institution of Finland (Kela). In five years, the number of users has increased more than elevenfold.

Semaglutide, sold under brands such as Ozempic and Wegovy, is the most popular. Originally designed as a drug for the treatment of type 2 diabetes, this type of medicine is not reimbursed if it is used for obesity alone. This means that Finns have to foot the bill themselves, which can be over €260 each month.

It is also unclear how effective this type of weight loss medication really is, but Pia Pajunen, an expert physician at Kela, says it is not a quick fix for losing weight.

If you stop using the obesity medication, the weight often starts to increase again quickly. It’s important that both doctors and patients are aware that research shows these medications generally need to be used long-term, she says in a press release.

Good fitness may prevent dementia

People at risk of dementia can reduce their risk by improving their fitness, according to a study from Karolinska Institutet. The study shows that the risk can be reduced by up to 35%.

In the study, published in the British Journal of Sports Medicine, researchers used data from 61,214 dementia-free people, drawn from the UK Biobank database. The participants, who were aged between 39 and 70, were followed over a period of 12 years.

On enrollment, participants completed a six-minute cycle test to measure fitness, and neurological tests were done to estimate their cognitive function. The researchers also examined genetic predisposition to dementia.

During the 12-year follow-up period, a total of 553 people were diagnosed with dementia, representing 0.9%.

The results show that better fitness is linked to reduced dementia risk and improved cognitive function. According to Weili Xu, Professor of Geriatric Epidemiology in the Department of Neurobiology, Care Sciences and Society, good fitness can reduce the risk of all forms of dementia by up to 35%.

– Our findings suggest that maintaining good fitness may be a strategy for preventing dementia, even among people with high genetic susceptibility, she says in a press release.

The researchers also emphasize that this is an observational study, so it is not possible to determine cause and effect. The number of dementia cases may also have been underestimated, they add, as UK Biobank participants are generally healthier than the general population.
