A examine of the well being advantages of a Mediterranean food plan with a low glycemic index

The prevalence of kind 2 diabetes is growing worldwide and is carefully linked to the elevated danger of creating heart problems.

A current examine by nutritionists at Chalmers College of Expertise discovered that consuming a Mediterranean food plan with a low glycemic index (GI), amongst others, has well being advantages that may assist forestall kind 2 diabetes.

In a present examine, in collaboration with Purdue College, Federico II College and Chalmers, the researchers checked out how diets with excessive and low glycemic index, GI, known as postprandial glycemia, affected insulin sensitivity to meals.

“Decreasing postprandial glucose ranges could also be a method to cut back the prevalence of kind 2 diabetes, as excessive food-related glucose can contribute to the event of the illness,” mentioned Theresa Horth, a doctoral pupil in vitamin and vitamin at Chalmers College. , and one of many researchers behind the examine.

Earlier research have proven that carbohydrate-rich meals play an essential position in GI postprandial blood glucose ranges, and that diabetics management glucose management by selecting meals which are low in GI. However there is no such thing as a consensus on how GI impacts non-diabetic folks, particularly within the context of a wholesome consuming sample (HEP).

“There are research displaying that Mediterranean (MED) HEP consumption might scale back the danger of creating kind 2 diabetes, however no earlier research have evaluated the results of high and low GI meals related to the MED-HEP food plan,” mentioned Theresa Hjort. .

Low GI could also be essential for the well being advantages of a Mediterranean food plan

Within the examine, 160 individuals prone to creating kind 2 diabetes accomplished a 12-week dietary intervention assessing the results of MED-HEP with excessive and low GI. Contributors consumed half of their every day carbohydrates as low-GI meals similar to pasta, brown rice, flatbread, or high-GI meals similar to jasmine rice, potatoes, mashed potatoes, and couscous, in addition to fruits, greens, and all carbohydrate-rich meals.

“We predicted that glucose ranges have been decrease after a low GI food plan than after a excessive GI food plan – and the variations between teams elevated over time within the examine. This means that the glucose stage rises after consuming meals with a excessive GI for 12 weeks, ”mentioned Theresa Horth.

In line with the researchers, this examine reveals that GI impacts blood glucose ranges in individuals who don’t have diabetes, though they comply with a correct Mediterranean food plan. That’s: a nutritious diet (MED-HEP) doesn’t change a excessive GI food plan, so it is very important take into consideration the standard of carbohydrates in meals and select meals with a low GI.

“As a result of low-GI meals, similar to pasta, are a part of the normal Mediterranean food plan, our outcomes recommend {that a} low-GI Mediterranean food plan could also be an essential ingredient in well being advantages.”

The outcomes will be helpful when trying to find biomarkers

Chalmers researchers say the outcomes may very well be very helpful when searching for particular biomarkers for meals excessive and low GI.

“Such biomarkers can be utilized in epidemiological research to enhance understanding of the position of GI diets in well being and illness. We additionally use intensive knowledge collected to higher perceive the position of food plan, intestinal microbiota and plasma metabolites in interpersonal communication. Variations in glucose response to food plan.” – says Theresa Hort.

The examine was printed Vitamins.
