Swedish Paediatric Association: “No screen time for children under two”

Published 5 November 2023

Screen time has significant negative effects on young children.

Children under two years of age should not use screens at all, according to the new advice from the Swedish Paediatric Society. Children between the ages of 2-5 are recommended to use screens for no more than one hour a day.

Research indicates that children’s development can be negatively affected if they start using screens too early. Among other things, screens can block important training during the early years that the child needs during that developmental period. A later screen debut is also linked to better language development. Studies suggest that there is also a correlation between early use of screens and poorer development of cognitive abilities as well as risks for myopia and overweight, the Swedish Paediatric Society points out in their new advice.

The Swedish Paedriatic Society’s advice is in line with the public health authorities of both Norway and Denmark, which also discourage screen time for children under two years of age. The World Trade Organization has also advised completely against screens for 1-year-olds since their advice was issued in 2019.

Both the National Agency for Education and the Public Health Agency are currently in the process of developing their own recommendations. The Swedish Paediatric Society had initially intended to publish their advice in conjunction with the completion of those investigations, but it may take an additional one or two years, and they believe that the recommendations are in demand now, which is why they chose to publish them.

– We think there is such a great demand from the public, child health centers, and preschools, and at the same time research has accumulated. There has been so much research on small children, screen time, and language development that we feel we must share this with the country’s parents, says Ulrika Ådén, chairperson of the Swedish Paediatric Society, to the tax-financed SVT.

Engaged adults

The Swedish Paediatric Society believes that it is the engagement of adults that is important for children’s development and that children in no way miss out on anything when they do not learn to use screens early.

“Children learn best in interaction with adults, and there is still no evidence that digital tools could be as good at teaching your child new things as you are”, the recommendations state.

Furthermore, they advise against using screens to divert negative emotions, instead recommending bringing along a small toy or book if needed.

“If you distract or comfort the child with a screen, this risks creating more conflicts, more nagging about screens over time, as well as preventing the child from developing their ability to regulate their emotions in the best way”.

Use of obesity drugs surges in Finland

Published 27 May 2025

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

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.

Ultra-processed food may increase the risk of cardiovascular disease

Published 21 May 2025

Extra-processed foods and sugar-sweetened beverages are linked to a particularly increased risk of premature death from cardiovascular disease, according to a study from Lund University.

Ultra-processed food is food that has undergone extensive processing and contains a high proportion of added chemicals compared to “regular” processed food. This type of food is often cheap, heavily marketed and has become an increasingly important part of the Western diet in recent years.

In the study, published in Clinical Nutrition, researchers followed 27 670 participants from the Malmö Diet Cancer Study over 23 years, with funding from the Swedish Heart and Lung Foundation.

The results show that a high intake of highly processed foods and sugar-sweetened beverages is linked to an increased risk of premature death, death from cardiovascular disease and death from respiratory disease. There is an increased risk for women.

– Over-processed foods are often rich in salt, fat and added sugars, but often poor in fiber, vitamins and nutrients. Limiting intake can reduce the risk of premature death, says Emily Sonestedt, associate professor at Lund University and lead researcher of the study, in a press release.

Ultra-processed food is markedly different from what humans have been eating for thousands of years, but the long-term effects on health have yet to be studied in depth. However, links between this type of food have previously been made to depression and type 2 diabetes. At the same time, the researchers point out that more studies are needed on the subject.

–  More research is needed to better understand how ultra-processed food affects the body. In future studies, we will be able to analyze current dietary data in the Swedish population and learn more about the relationship with cardiovascular disease, says Kristina Sparreljung, Secretary General of the Swedish Heart-Lung Foundation.

Sauerkraut may help your stomach

Published 11 May 2025

Sauerkraut may protect the intestinal lining from inflammation, according to an American study. During fermentation, the nutritional content of cabbage changes – including an increase in levels of lactic acid, amino acids, and other beneficial substances that are formed during the breakdown and can promote gut health.

Fermentation is a natural process where microorganisms like lactic acid bacteria and yeast break down sugars in food. This often results in the conversion of sugar into lactic acid or alcohol. The process not only helps preserve the food – it also produces probiotics, meaning live bacteria that are beneficial for the gut.

Fermented foods have been eaten for thousands of years around the world. For example, eating fermented vegetables makes the nutrients in the food easier for the body to absorb, and some studies show that vitamin levels can actually increase. There are also studies that suggest fermented foods can have positive effects on health, particularly for digestion and the immune system.

Sauerkraut better than raw cabbage

Researchers at the University of California Davis in the USA tested whether the nutrients in sauerkraut could help protect intestinal cells from inflammation-related damage. The study compared sauerkraut, raw cabbage, and the brine left over after the cabbage fermentation process.

The experiments were conducted on an artificial intestinal wall exposed to inflammation by adding so-called cytokines – which are known to damage the intestinal lining. These can be activated in the gut, for example, by consuming too much ultra-processed food or too much sugar or salt.

Fermentation increases beneficial substances

The results showed that sauerkraut can protect the intestinal lining from inflammation caused by cytokines. Raw cabbage and the brine, however, did not help protect the gut. It didn’t matter whether the sauerkraut was store-bought or homemade.

Chemical analyses show that fermentation changes the nutritional profile of cabbage and increases the amount of beneficial metabolites such as lactic acid, amino acids, and plant compounds, which in turn are linked to gut health. These changes may explain why fermented foods are often associated with digestive benefits.

– Some of the metabolites we find in the sauerkraut are the same kind of metabolites we’re finding to be made by the gut microbiome, so that gives us a little more confidence that this connection we found between the metabolites in sauerkraut and good gut health makes sense, says Professor Maria Marco in a press release.

The researchers have found hundreds of different metabolites that are formed during fermentation and that they are now working to determine which ones play the biggest role in supporting long-term gut health. The next step in the research is to conduct studies in humans to see if the gut-protective metabolites found in sauerkraut can have the same positive effects when included in the daily diet, as was shown in the lab.

A little bit of sauerkraut could go a long way, she says. We should be thinking about including these fermented foods in our regular diets and not just as a side on our hot dogs.
