The Claim

Replacing refined sugars with maple syrup for 8 weeks significantly reduces the abundance of Klebsiella species in the gut microbiota of overweight adults with mild metabolic alterations, compared to substitution with sucrose syrup.

Source: Substituting refined sugars with maple syrup decreases key cardiometabolic risk factors in individuals with mild metabolic alterations: a randomized, double-blind, controlled crossover trial.

Cause and effect
1 study reviewed
In plain English

In overweight adults with mild metabolic alterations, replacing refined sugars with maple syrup for 8 weeks results in a lower abundance of Klebsiella species in the gut microbiota than replacing refined sugars with sucrose syrup.

See the scientific wording

Replacing refined sugars with maple syrup for 8 weeks significantly reduces the abundance of Klebsiella species in the gut microbiota of overweight adults with mild metabolic alterations, compared to substitution with sucrose syrup.

Why this might work

Maple syrup contains special plant compounds and fiber that feed good gut bacteria and slow down sugar absorption. This changes what the bad bacteria like Klebsiella can eat and how they behave, causing them to die off. At the same time, the good bacteria produce substances that calm down inflammation in the gut, making it harder for Klebsiella to survive and multiply.

  1. Study: Substituting refined sugars with maple syrup decreases key cardiometabolic risk factors in individuals with mild metabolic alterations: a randomized, double-blind, controlled crossover trial.

    This study found that when overweight people swapped their regular sugar for maple syrup for two months, the bad gut bacteria called Klebsiella went down—but didn’t go down when they used regular sugar instead.
