- Researchers used metabolic analysis to investigate the health effects of a healthy Scandinavian diet (HND).
- They found that diet had a positive effect on glucose metabolism, cholesterol, and cardiac metabolism risk.
- They conclude that metabolic analysis is an effective way to assess dietary outcomes.
HND is composed of berries, fish, root vegetables and canola oil.Known to benefit various aspects of health, including
Studies also show that HND reduces risk
Since research usually relies on subjective tools such as food consumption questionnaires, nutritional research often faces challenges due to lack of objective means.use Biomarker Instead, researchers can more accurately measure the health effects of their diet.
In this study, Scandinavian researchers used data from randomized controlled trials to assess the metabolic effects of HND on glucose metabolism, blood lipid profiles, and inflammatory markers.
Examination of participants’ blood and urinary metabolites showed a link between tighter dietary adherence and greater benefit to low-grade inflammation and lipid profiles, as well as indicators of glucose metabolism. I found that there is.
“The original analysis compared participants in the intervention group. [with] Dr. Christina C. Dahm, an associate professor of public health at Aarhus University in Denmark, Today’s medical news.. Dr. Dam was not involved in the study.
“This reanalysis uses plasma and urinary metabolites to group people with high levels of metabolites supplied by either an intervention diet or a control diet,” she added.
The study will be displayed in Clinical nutrition..
The 2013 study enrolled 200 participants in overweight and metabolic syndrome. The average age of the participants was 55 years.
After the first four weeks of participants eating a typical diet, researchers randomly assigned them to follow either the HND or control diet, which is defined as the average nutritional intake across Scandinavian countries.
The researchers then instructed HND Group participants to increase their consumption of whole-grain products such as rye and barley, in addition to berries, fruits and vegetables.
Control groups were instructed to eat low-fiber wheat products, including refined white bread and pasta, and not curb consumption of vegetables and fruits.
Both diets contained the same amount of calories to stabilize participants’ weight throughout the study. Researchers followed participants for 18 or 24 weeks and were asked to provide blood and urine samples at the beginning and end of the intervention, and at week 12.
In the current metabolic profiling study, researchers analyzed data from 98 participants in the HND group and 71 participants in the control group.
They found that most people who stick to HND have different fat-soluble metabolites in their blood than others. Researchers have linked these metabolites to better glucose regulation, improved cholesterol profiles, and reduced risk of cardiac metabolism.
These findings, based on the initial results of 2013, state that HND has a positive effect on lipid profile and inflammation, but not on glycemic metabolism.
“Participants with high levels of metabolites fed from the Scandinavian diet had lower triglyceride levels than participants with low levels of metabolites, even though none of them lost weight during the study. “Dr. Derm said.
“Assuming that eating more Scandinavian diets results in higher levels of blood metabolites, this means that a higher quality diet can improve some health parameters, even if you are not losing weight. . “

But Dr. Darm said he didn’t know how clinically important the results were.
To explain their findings, researchers say that fish, flaxseed, sunflower, and rapeseed (all HND’s staple foods) contain healthy fats.
“We can only speculate why changes in fat composition bring so great benefits to our health,” said Lars Ove Dragsted, one of the authors of the study. “But we can see that the lack of highly processed foods and the low levels of saturated fat in animals have a very positive effect on us.”
“The fat composition of the Nordic diet, which is high in omega 3 and omega 6 unsaturated fats, [probably explains many of] “Even if a participant’s weight remains constant, the health effects of a Scandinavian diet,” he adds.
Dr. Christopher Gardner, Professor Remborg Farkhar of Stanford University, said he was not involved in the study MNT The findings are not surprising. “Interventions focus on health foods, especially berries, vegetables, fish, whole grains, [low fat] Dairy products, canola oil. “
“I can think of multiple mechanisms for the benefits of heart metabolism, regardless of weight loss: less saturated fat, more unsaturated fat, more fiber, and lower sodium. All will have beneficial effects on fats, glucose, blood pressure and inflammation, “he added.
The authors of this study conclude that assessing metabolites is an effective way to assess the health benefits of different diets.
However, they say there are some limitations to their findings. For example, their analysis may have overlooked some metabolites that may have been detected by other profiling techniques. They also say their sample size was relatively small.
Dr. Gardner added that these results may be due to a generally healthy diet rather than something specific to HND.[The results could have arisen from the] Scandinavian, Mediterranean, Vegetarian, DASH, [or] All foods Plant-based diets, or other half a dozen.Many of the components of [HND] Similar to these [other diets].. “
