Blueberries Lower Fat-Induced Gut Inflammation in New Study
Wageningen, Tuesday, 13 October 2026.
Wageningen University research shows blueberries can reduce fat-triggered gut inflammation by up to 46%, counteracting the harmful absorption of bacterial toxins driven by oils like palm oil.
How Dietary Fats Trigger Intestinal Inflammation
In the intersection of food science, medicine, and healthtech, researchers at Wageningen University & Research (WUR) in Wageningen, Netherlands, have uncovered critical insights into how specific dietary fats interact with the human gut [1]. Led by PhD candidate Aina Casademont Roca, the research team utilized an advanced laboratory-simulated small intestine model containing human intestinal and immune cells to study the intestinal absorption of lipopolysaccharides (LPS) [1]. LPS is a bacterial compound known to trigger mild, systemic, long-term inflammatory responses when it breaches the intestinal barrier and enters the bloodstream to interact with immune cells [1].
The Protective Mechanism of Berries
To mitigate fat-induced inflammatory spikes, the WUR research team evaluated the therapeutic potential of dietary fruits [1]. Freeze-dried blueberries, blackberries, and bananas were introduced into artificial gut models to observe their capacity to tone down inflammatory pathways [1]. Blueberries delivered the most substantial mitigation, dampening the palm-oil-induced inflammatory reaction by up to 46 percent [1]. Blackberries also exhibited inhibitory effects against gut inflammation [1].
Broader Applications in Healthtech and Agri-Food Education
Looking ahead, the Wageningen team plans to transition to more complex biological systems, including organoids—three-dimensional mini-organs that replicate human intestinal architecture—followed by animal studies to fully elucidate the molecular pathways before evaluating human trials [1]. Beyond laboratory discovery, WUR is actively connecting nutritional science with public education [4]. In October 2026, WUR’s Smaaklessen team announced a joint initiative with LekkerBoer starting in January 2027 to consolidate the Food Challenge and Smaaklessen onto a single digital learning portal for secondary education across Dutch provinces including Overijssel, Flevoland, Groningen, and Utrecht [4].
