Scientists announced that the results of their recent diet study showed that multiple, rather than just single, foods with anti-inflammatory effects greatly reduce inflammation in the body, decrease bad cholesterol by 33%, blood lipids by 14%, blood pressure by 8% and a risk marker for blood clots by 26%, while improving memory and cognitive function.
“The results have exceeded our expectations! I would like to claim that there has been no previous study with similar effects on healthy subjects,” says Inger Bjorck, professor of food-related nutrition at Lund University and head of the University’s Antidiabetic Food Centre.
Forty-four healthy, overweight people between the ages of 50 and 75 took part in the diet study. For four weeks they ate foods which are presumed to reduce low-grade inflammation in the body, a condition which in turn triggers metabolic syndrome and thus obesity, type 2 diabetes and cardiovascular disease.
The test diet was high in antioxidants, low-GI foods (i.e. slow release carbohydrates), omega fatty acids, wholegrain products, probiotics and viscous dietary fiber. Examples of foods eaten were oily fish, barley, soy protein, blueberries, almonds, cinnamon, vinegar and a certain type of wholegrain bread. Some of the products in the food portfolio are not yet available in the shops, but were developed specifically for the study.
“Our purpose was to find out which preventive effect can be obtained on established risk markers by combining food concepts with an expected positive impact on inflammation.”
Inger Bjorck believes that the study may have a broader impact on society. “We hope that these results on healthy subjects will inspire more intense preventive efforts in society.”
It is not possible to tell precisely which food factors have greater or lesser impact on the research results.
“That’s the point. We believe in the idea of combined effects. Drug or specific products with health claims affect only one or maybe a couple of risk factors. By a combination of food you can in a simple and striking way affect many risk parameters simultaneously,” explains Inger Bjorck.
