Replacing some of the refined sugar we consume with maple syrup would have positive effects on certain risk factors associated with cardiometabolic health.

We would do well to replace some of the refined sugar we consume daily with maple syrup, suggests a study just published in the scientific journal The Journal of Nutrition. "We observed significant cardiometabolic effects by replacing around 20% of the calories consumed daily in the form of sugar with maple syrup. From a practical point of view, this is a dietary modification that can easily be envisaged", comments the person in charge of the study, André Marette , professor at Laval University’s Faculty of Medicine and researcher at the Centre de recherche de l’Institut universitaire de cardiologie et de pneumologie de Québec and at Laval University’s Institut sur la nutrition et les aliments fonctionnels.

A few months ago, Marette’s team published the results of a study carried out on mice fed a diet rich in fats and sugars. Analyses had shown that replacing a quarter of the sugar consumed daily with maple syrup reduced insulin resistance, refined sugar digestion, intestinal glucose absorption and liver inflammation.

In the light of these results, the research team conducted a similar experiment with a group of 42 people who were overweight (average body mass index 28), but not yet suffering from any major health problems. For 8 weeks, the subjects were asked to modify their diet so as to replace part of their daily sugar intake with maple syrup. This substitution was equivalent to 5% of the total calories consumed each day, or between 20 and 40 ml of maple syrup.

Analyses revealed that this substitution was associated with improved glucose metabolism, reduced blood pressure and lower abdominal fat reserves. "This last result seems particularly important to us because these fats are a major risk factor for cardiometabolic diseases", stresses Professor Marette.

The researcher puts forward two hypotheses to explain the beneficial effects of maple syrup. "Firstly, the polyphenols present in maple syrup could reduce the activity of an enzyme, intestinal alpha-glucosidase, which splits sucrose into glucose and fructose. As a result, fewer absorbed carbohydrates would enter the bloodstream, resulting in less variation in blood glucose levels. On the other hand, the changes we observed are associated with modifications in the composition of the intestinal microbiota. These changes could have repercussions on the host’s inflammatory response."

Maple syrup is a sugar and should be consumed in moderation," says Professor Marette. However, our study suggests that this sweetener could mitigate some of the negative effects of refined sugar. It could therefore be beneficial to replace some of the sugar we consume with maple syrup."
